How COSC’s Homeowner Handbook Can Help You

The purpose of this manual is to provide owners of existing and newly constructed homes with information and resources to assist them in efficiently operating and maintaining their homes.

The information provided is guided by the fundamental green building principles of durability, sustainability, energy efficiency, healthy indoor air quality, and water and resource management. Properly maintaining your home increases its durability, contributing to the longevity and value of your property. Incorporating green building techniques improves the comfort and health of your family while saving money and environmental resources.

Inside this handbook, you will find a list of maintenance tasks and projects conveniently organized by season, an alphabetical listing of the home’s features with “best practices” advice to consider for each, a comprehensive overview on how to operate your home and a useful list of resources.

Remember to utilize COSC and our broad network of professionals and local experts as your key resource. There are many homeowner manuals out there; however, this is the only one that is uniquely written by local experts with specific guidance on our regional climate and maintenance best practices for Iowa.

We encourage you to refer to COSC’s website often for more current and in-depth information (www.icosc.com). We also encourage you to become members of COSC and engage in our local educational and networking opportunities so that you can connect with the vast resources available to support your steps toward a healthier, more efficient and well maintained home.

Iowa’s Trusted Educational Resource for Sustainable Building

wHaT IS Green bUILdInG?

green building is the practice of creating, retrofitting and rehabbing structures using processes that are healthy, environmentally responsible and resource-efficient throughout a building’s life from site selection to design, construction, operation, maintenance, renovation and deconstruction. This practice enhances and complements the classical building design concerns of economy, utility, durability and comfort. green construction methods can be integrated into buildings at any stage; however, the most significant benefits can be obtained if the design and construction team takes an integrated approach from the earliest stages of a building project. Throughout the planning process, green buildings are designed to reduce the overall impact of the built environment on human health and the natural environment by:

Using energy, water and other resources efficiently•

Protecting occupant health and improving employee productivity and family comfort •

Reducing waste, pollution and environmental degradation •

Minimizing maintenance issues and costs •

Creating durable structures built to last•

For example, green buildings may:

Incorporate sustainable materials in their construction (e.g., reused, recycled-content, or made from renewable •

resources).Create healthy indoor environments with minimal pollutants (e.g., reduced product emissions and good •

ventilation). Include water reduction strategies inside and out (e.g., low flow fixtures, native plants in landscaping, rain •

barrels).

The built environment has a vast impact on the natural environment, human health, and the economy. By adopting green building strategies, both economic and environmental performance can be maximized. Potential benefits of green building can include:

Environmental benefitsEnhance and protect biodiversity and ecosystems•Improve air and water quality•Reduce waste streams•Conserve and restore natural resources•

Economic benefitsReduce operating costs•Create, expand and shape markets for green products and services•Improve occupant productivity•Optimize life-cycle economic performance•

Social benefitsEnhance occupant comfort and health•Heighten aesthetic qualities•Minimize strain on local infrastructure•Improve overall quality of life•

Survey Plat: Many property owners do not have a current survey plat of their property. A legal survey is the only way to know exactly where your property lines and corner pins are located. Often disputes with neighbors over ownership of trees, fences and other lot features can be resolved with a survey plat. Also, the placement of new structures on setback lines requires the exact location of the property lines. It is also important to have your survey plat recorded with the county recorder.

Development/Property Plat: This document is a companion to the survey plat and illustrates the location of your property within a larger development. These may be found at your county assessor’s office or website or from your local city building department.

Topographical Plat: Many county assessor’s or engineer’s offices have topographical maps of their county. This is a valuable document to have in your possession, as it can aid you in designing or installing future property improvements.

Easement(s) Plat(s): Easement agreements and plats are essential to keep in your possession. Easements can affect your ability to construct new property improvements or install new plantings, etc.



Property Photographs: It is a good idea to take photographs of your property periodically and date them and keep them for future reference. Photographs of all property improvements can be very helpful in resolving insurance claims after accidents and severe weather events.

Aerial Photographs: Aerial photographs can be very helpful, especially for rural property owners. There are private companies around Iowa that perform this service.

Soil Survey Information: Each county in Iowa has a soil survey of its entire land area. These surveys are available at no charge and can be very helpful in designing new property improvements and plantings. The survey may also be helpful in obtaining various building or zoning permits. These are available at every county soil conservation office.

Home Inspection Documents: Any home or property inspections that may have been performed on your property should be retained for review.

Building Performance Rater Documents: If a building performance rating or other performance testing has been performed on your property, these documents should be retained to help evaluate the effectiveness of future property performance improvements.

Radon Test Documents: Any radon test results should be dated and retained with other building performance documents. This is important in Iowa because we have the largest percentage (71.6%) of homes above the US EPA action level of 4pCi/L, which is more than any other state in the US. For more information see www.idph.state.ia.us/eh/radon.asp.

Lead Testing/Abatement Documents: Any lead testing or abatement documents should be dated and retained with other building documents. Statewide, the prevalence of lead poisoning among children under the age of six years is more than four times the national average. For more information see www.idph.state.ia.us/eh/lead_poisoning_prevention.asp.

Asbestos Testing/Abatement Documents: Any asbestos testing or abatement documents should be dated and retained with other building documents.

Pest Inspection/Treatment Documents:Any pest inspection or treatment documents should be dated and retained with other building documents.

Heating Ventilation and Air Conditioning (HVAC) Inspection/Servicing/Permits Documents:Any HVAC system inspection or servicing documents should be dated and retained with other building documents.

Building Permit & Inspections:Any required building permits or building inspection documents should be dated and retained with other building documents.


5HOmeOwner HandbOOk

Zoning Permit:Any existing zoning permits should be dated and retained with other property documents.

Electrical Permits & Inspections:Any electrical permits and inspection documents should be dated and retained with other building documents.

Plumbing Permits & Inspections:Any plumbing permits and inspection documents should be dated and retained with other building documents.

Utility Permits:Occasionally, utilities require permits for the installation of their services. If such permits exist, they should be dated and retained with other building or property documents.

Utility Agreements:Any utility easements or other agreements or plats should be dated and retained with other building or property documents.

Utilities Location Documentation:If a utility location service is performed, photographs should be taken of the locate marks. The photographs should be dated and retained with other property documents for future reference.

Utility Incentives Documents:Often, utilities servicing the property offer monetary incentives for various property improvements. If any incentives were utilized on the property, all incentive documents should be dated and retained with other building documents.

Private Well Documents:Some localities require permits, drawings and inspections for the installation of private water wells. If such documents are required, they should be dated and retained with other property documents.

Rural Water Documents:Many rural properties are served by a rural water system. Any agreements, easements, drawings or plats should be dated and retained with other property documents.

Septic System Permit/Inspections & Percolation Tests:Most localities require a permit and inspections for the installation of a private septic system in areas not served by a public sewer system. Any septic permits, drawings or inspection reports should be dated and retained with other property documents.

Driveway/Sidewalk Permits & Inspections:Some localities require permits and inspections for the installation of new driveways or sidewalks. Any permits, drawings or inspection reports should be dated and retained with other property documents.

Curb-Cut Permits & Inspections:Some localities require permits and inspections for cutting street curbs for the installation of property improvements. Any permits, drawings or inspection reports should be dated and retained with other property documents.



Other Permits & Inspections:Depending upon local requirements, other permits and/or inspections may be required. A complete record of theses permits and inspections should be retained with other property documents.

Property Abstract (Note Location Where Stored: ______________________________):A property abstract is the entire legal history of a property. Property abstracts can be very expensive to replace, so it is recommended that property abstracts be kept in a highly secure location such as a safe deposit box. Include a note in this handbook indicating where the property abstract is stored.

Real Estate Market Studies:If real estate market studies have been developed for your property, these documents should be dated and retained with other property documents.

Appraisal(s) (Note Location Where Stored: ______________________________):Property appraisals may be made available to property owners. An appraisal is a professional assessment of the property at a particular moment in time. Appraisals should be kept with other property documents. Because appraisals can be costly to obtain, it may be advisable to store them in a highly secure location such as a safe deposit box.

Real Estate Advertisements:Real estate advertisements for your property may be valuable for future decisions about property dissolution. Retain any real estate advertisements with this handbook.

Property Covenants:Many residential developments attach restrictive covenants to the purchase of the property. Covenants restrict the manner in which the property can be used. Copies of any restrictive covenants should be kept with real estate sales documents.

Real Estate Sales Documents (Note Location Where Stored: ___________________________):Real Estate sales documents should be kept in a highly secure location such as a safe deposit box. A note should be included in this handbook indicating where these documents are stored.

Property Tax Assessment(s):Property tax assessment documents should be retained annually with all other property documents.

Mortgage Documents (Note Location Where Stored: ______________________________):Mortgage documents should be kept in a highly secure location such as a safe deposit box. A note should be included in this handbook indicating the location of mortgage documents.

Insurance Documents:Property insurance policies should be retained in this handbook for future reference in the event of accidents or severe weather events.

Construction Drawings/Specifications/Shop Drawings/Renderings, etc.:Copies of all construction drawings, construction specification, shop drawings, soil analysis reports, renderings or other construction drawings should be dated and retained for future reference.


7HOmeOwner HandbOOk

Construction Agreements/Work Change Orders (General Contractor):If new construction or maintenance has been performed on the property, copies of all construction agreements and/or work change orders from your general contractor should be maintained in this manual.

Subcontract Agreements:It is important to request and retain any subcontract agreements pertinent to all work performed on the property.

All Pertinent MSDS Documents:If new construction or maintenance has been performed on your property, request copies of MSDS (Material Safety Data Sheets) for all materials and products used in the work performed on the property. File these documents with this handbook.

Certificate of Occupancy:In localities where building codes are enforced, a Certificate of Occupancy (COO) is required before any new home or addition can be legally occupied. Attach the COO to the original building permit and retain with this handbook.

Material Price Quotes:If material price quotes for construction materials can be obtained from contractors, it would be beneficial to retain these for potential future reference.

Material Warranties/Service Agreements:Request product and contractor warranty documents and/or service agreements from all contractors for all products and services provided during any construction work performed on the property.

Receipts for all Materials and Labor Purchases Pertinent to the Property(Filed Chronologically for the Entire Period of Interaction with or Ownership of the Property):Materials and labor receipts are essential in preparing tax documents, providing information for insurance claims, or researching sizes, colors and specifications for replacing damaged or outdated materials.

deTaILed InFOrmaTIOn

eXTerIOr FeaTUreS

DecksDecks are most commonly constructed of one of three different types of materials: pressure treated lumber, composite lumber or naturally decay resistant lumber species (Cedar, Redwood, Cypress, etc.). Each material has advantages and disadvantages pursuant to its use. Pressure treated lumber is inexpensive, but the treatment materials can present environmental risks and can present corrosion problems with fasteners and metal structural anchors. In Midwest climates, all wood decks need to be sealed periodically to resist detrimental weathering. Composite lumber is less subject to warping, bowing or cupping.4

DrivewaysDriveways are significant contributors to pollutant runoff into storm drains and streams. In new construction, install pervious driveways using pervious asphalt, concrete, pervious pavers or gravel. For more information contact the Iowa Strom Water Education Program (ISWEP), www.iowastormwater.org.

Exterior GradingAll water should be directed away from the home and other outbuildings at a minimum slope of 6” per 10’ to minimize potential water damage to structures.

Gardens: Flowers/Vegetable/Herbgardens are highly desirable for their aesthetic and nutritional qualities. gardens are, however, subject to predation from insects, animals and diseases. Many homeowners use chemicals to deal with these problems. Although these products are very effective, they can be problematic when absorbed by the vegetables and herbs we consume and when allowed to runoff into our natural freshwater systems. There are many non-toxic options for dealing with garden predation problems. Many of these options are also less expensive that their chemical counterparts. It is preferable to use non-toxic natural methods whenever possible and practical.

gardens also produce large amounts of waste and plant debris. It is beneficial and cost-effective to re-use such plant waste on the property as mulch or through composting rather than disposing of them offsite.

OutbuildingsOutbuildings are subject to the same durability issues as a home. Outbuildings should be constructed a minimum of 6” above the existing grade. grading around outbuildings should provide a minimum slope of 6” in 10’ away from the building. Outbuildings that are built close to other buildings can direct water run-off toward the home or other buildings. Eave spouting systems or water catchment systems should be utilized to control water run-off. All penetrations through the building envelope of outbuildings should be properly flashed.3

PatiosConcrete patios are impervious and have the potential to direct rainwater runoff toward the buildings if settling has occurred near the foundation. Properly constructed concrete patios should be slightly sloped away from the building. Concrete patios often pull away from the building over time. A quality polyurethane sealant should be used to seal the



crack next to the building. Brick or stone patios are more pervious, but can still pose potential drainage problems if the grade has settled near the foundation.

Rain Gardens/Bio-SwalesA rain garden is an area in the natural runoff plane into which storm water is directed and allowed to soak into the soil. Rain gardens are usually planted with native grasses and water-friendly perennial plants that help maintain a healthy soil profile. A general rule of thumb is that the size (area) of the rain garden should be equal to at least 10% of the roof area being drained. The goal of a rain garden is to retain all of the runoff water on the site.8

A bioswale differs from a rain garden in that it is designed to capture some of the runoff water, but usually has an outlet for overflow. Bioswales are also planted with native grasses and plants similar to a rain garden and generally follow the natural drainage path of the site.9

Retaining WallsRetaining walls should be constructed so that they slope back slightly (3-5 degrees) and should be tied into the sub-grade behind them. Also, retaining walls should be well drained to prevent soil saturation behind them and to reduce the effects of freeze/thaw action.5

SidewalksSidewalks are essentially public spaces that the homeowner must maintain. Replacing sections of sidewalks that can present trip hazards is essential in contributing to a safe neighborhood. Winter snow removal is also required in most localities. Concrete sidewalks are also impervious surfaces. When replacing sidewalks, consider the pervious paving options if allowed under local codes.

Subsurface DrainageSubsurface drainages, such as that from foundation drains, can be routed to a sump pump or to surface drainage if the lot grade allows. Either option should result in the drained water being retained on the property to the greatest extent possible by utilizing the strategies mentioned under Water Management previously.

Sump Pump DrainageSump pump drainage should be directed to an area of the property where it can be allowed to slowly soak into the soil as mentioned previously under Water Management.

Surface DrainageSurface drainage and roof runoff are the most problematic in terms of runoff of contaminants and debris. Strategies such as pervious paving, rainwater collection and reuse, rain gardens or bio-swales should be used in an attempt to retain all rainwater on the site.

Trees/Shrubs/Windbreaks, etc.Preventive trimming of large trees in close proximity to buildings will reduce the potential of fallen tree damage to the buildings during windstorm events. Winter is the best time to perform tree trimming because they are in a dormant phase with cold temperatures and are less subject to insect damage and diseases. Trimming of shrubs may be desirable for reasons of appearance, but less trimming improves the wildlife utilization of the shrubs. Properly constructed windbreaks include two or more varieties of deciduous and coniferous trees and shrubs of different heights and densities. Over time, some of the varieties may die and require replacement. Staggering the timing of replacement over several years will prevent a major loss of a single variety at one time within the windbreak.6



Turf/Groundcover, etc.Many homeowners prefer turf grass lawns, and they often use fertilizers, herbicides, and pesticides to improve the visual quality of the lawn. The problem with using these products is that they have the potential to run off with stormwater during rain events and allow them to enter our streams, rivers, and lakes. Minimal use of these products is recommended. greater use of natural prairie grasses and flowering plants will improve soil quality, eliminate the need for chemicals and provide better wildlife habitat.7

Water ManagementMost water runoff problems are the result of impervious surfaces that allow pollutants and debris to make their way into natural fresh water systems. A good goal for a homeowner is to attempt to hold all rainwater on the site allowing it to slowly soak into the soil rather than rapidly runoff. This goal can be achieved by the use of various strategies such as pervious paving, direct rainwater collection and reuse, rain gardens, bio-swales, etc.

Water RunoffAll surface water runoff should be retained on the property to the greatest extent possible. This can be accomplished through rainwater harvesting (rain barrels, cistern, etc.), pervious surfaces, rain gardens, bio-retention cells, etc. The goal is to prevent erosion and to eliminate sediment and pollutant transfer from the property to storm drains or steams.2

Attic VentsAttic vents should be inspected annually to assure that they are free of obstructions that can restrict airflow.

Basement /Egress WindowsBasement and egress windows are unique in that they are often installed below the surface grade and are, therefore, subject to potential water leakage problems. All basement and egress windows should be installed with a drainage system that has the ability to drain rainwater from below the window during severe weather events. Egress windows need to have a minimum area of 5.7 sq. ft. They must have a minimum clear opening width of 20”, and the maximum sill height above the floor is 44”. Egress wells must have a minimum area of 9 sq. ft. Wells that are deeper than 44” must have an integral escape ladder.18

Brick/StoneBrick and stone cladding should always be installed with a drainage/drying air space behind the cladding. Drying is particularly important with brick and stone cladding because of the potential for freeze-thaw damage during winter months. Brick or stone cladding should only be sealed on the exterior with a breathable sealant. A breathable sealant should be available from a masonry or paint vendor.

Door HardwarePeriodic lubrication of exterior door hardware is required. Locking and latching hardware should only be lubricated with graphite (never oil). All exterior door hinges should be lubricated with a light machine oil (3-in-1, etc.).

Eave Spouting/Gutter Systems Eave spouting systems need to be cleaned in the spring and the fall and inspected for leaking joints. Leaking joints need to be completely dried and sealed with a polyurethane or butyl sealant. Eave spouting fasteners should be inspected to insure their tightness. Downspout extensions should extend a minimum of four feet from the foundation and terminate on a splash block or gravel drain. If ice damming occurs and persists, it is advisable to remove the damming before it allows water to infiltrate the structure. This process is dangerous, and great care should be taken to assure safety during the ice dam removal. To help prevent ice dams, a snow roof rake with a long handle and blade can be used to remove snow from the roof.

Exterior DoorsExterior doors are essential for access to, and egress from, homes. Doors are also an essential element of the security function of a home. Because of their constant usage, doors are very prone to wear and damage. Wear and damage reduce the door’s effectiveness at controlling air leakage and providing security. Doors should be inspected semi-annually in the spring and autumn. There are various door types that may require different inspections. Such inspections should include:

Exterior Swing DoorsSwing doors are the most common and most used type of exterior door. Because of their frequent use, problems or malfunctions are often apparent soon after they develop. The most frequent problems involve improper latching, dragging or difficulty closing, noticeable drafts and water leaks.



Water leaks are the primary concern. There are many possible reasons for water leaks with doors. Most often these involve poor flashing or a failed sealant. If you cannot easily identify the source of the leak and repair it, you should consult an experienced carpenter to diagnose and repair the problem.

Most of the homes constructed in Iowa are constructed with wood framing. Wood is a natural material that is subject to movement during its initial drying process as well as during seasonal variations in humidity. This movement can affect the latching and closing of a door. Repairing these conditions may involve shimming or possibly the removal and reinstallation of the door. Such repairs may best be done by an experienced carpentry contractor.

If a door closes properly but does not latch, an adjustment of the strike plate is required. Some strike plates are made to be adjustable. Others may require an experienced carpenter to repair.

To keep the lock mechanism operating properly, an annual application of graphite powder or fluid, commonly found at home improvement stores, into the keyway of the lock mechanism will keep the lock working properly. never apply oils or other liquid lubricants to lock mechanisms.

Inspect all of the door weather-stripping. Look for loose, missing or shrunken weather-stripping and repair or replace as necessary.

Inspect the threshold and door bottom weather-stripping. Some door thresholds are adjustable to correct the effects of wear. Look for the evidence of light between the door and the threshold. If the threshold is adjustable, adjust until light is no longer visible and the door closes properly. If there is visible light below the door and the threshold is not adjustable, you will need to replace the door bottom weather-strip. The replacement process varies by door brand, but most styles of door bottom weather-stripping are available from building supply retailers.

Sliding Exterior DoorsSliding exterior doors are subject to the same problems listed above under Exterior Swing Doors, but sliding exterior doors have the potential for problems that are unique to this type of door.

Because sliding exterior doors slide in a track, debris from foot traffic and wind blown debris can build up in the bottom track of the door causing the door to drag and cause excess wear on the door bottom weather-stripping. Door bottom tracks should be vacuumed regularly to remove debris.

Most sliding exterior doors have the ability to be adjusted for height and freedom of travel. If you have difficulty operating the door, adjustment may remedy the situation.

Sliding exterior doors may also be subject to difficult operation due to settling or sagging of the door header. If you have difficulty operating the door, and have attempted to adjust the door without success, you should contact a qualified carpenter to assess and repair the problem. Swinging Patio DoorsSwinging patio doors are subject to the same inspections as outlined under Exterior Swing Doors above.

Exterior French Swinging DoorsExterior French swinging doors are constructed as two opposing swinging doors. As such, they are subject to the same problems as listed above under Exterior Swing Doors. 16



Fascia and SoffitMany homes have aluminum-wrapped fascia and aluminum soffits. Although wrapped fascia can reduce exterior maintenance, the potential exists for premature deterioration if the fascia is not tightly fastened and sealed at the joints. Aluminum soffits are also prone to damage during wind storms. Aluminum soffit and fascia should be inspected annually and repaired to eliminate water infiltration, which, if left un-repaired, can lead to rapid deterioration as moisture trapped behind aluminum fascia cannot dry out.

FlashingsFlashings typically involve the shedding of water from dissimilar materials or building elements. This leaves them vulnerable to material and building movement that can result in leaks. All roof flashings should be inspected annually on flat roofs and every 3-5 years on sloped roofs.14

Natural VentilationIn this era of inexpensive energy, Americans have become reliant on mechanical systems to condition the air inside of our buildings. Many of us have forgotten or never were trained that nature can provide adequate ventilation and cooling at many times of the year. It is a natural phenomenon that outdoor air becomes cool and dry at night. Opening windows at night from mid-May through September, and closing windows during the daytime can greatly reduce cooling costs and can passively improve indoor air quality. The prevailing summer winds in the upper Midwest move from southwest to northeast. Opening windows on these sides of the home allows natural breezes to move through thus cooling and ventilating the home.

In two story homes or homes with clerestories it is also possible to ventilate during the daytime by capitalizing on the stack effect. Opening intake windows on the south side of the first floor and also opening exhaust windows on the north side of the second floor can provide significant temperature reduction during the daytime. This strategy will not reduce humidity, however.

Mechanical air conditioning is expensive, so utilizing natural ventilation can result in a significant reduction in energy costs.

Overhead Garage DoorsThe primary maintenance issues with overhead garage doors are periodic lubrication of the rollers and track with grease, and the periodic inspection of the weather-stripping. Crushed or damaged weather-stripping should be replaced.

Roofing

Asphalt ShinglesAsphalt shingles are the most common roofing materials used on American homes. Asphalt shingles are inexpensive, easy to install and easy to repair. The lifespan of an asphalt-shingled roof varies from 15-40 years. Asphalt shingles are subject to damage from high winds, hail, falling debris and ice damming. Maintenance of asphalt-shingled roofs consists of visual inspections following extreme weather events. Annual inspections for wear, curling and flashings is recommended.10

Built-Up RoofingBuilt-up asphalt roofing consists of alternate layers of asphalt-saturated roofing felt and liquid bituminous asphalt. Built-up roofs are quite common on large commercial and institutional buildings, but are seldom used on residences. If your home has a built-up roof, it must be inspected every spring. Inspect all flashings, curbs and parapets for separation or deterioration. In Iowa’s climate, built-up roofs require periodic re-coating (typically 2-4 years).13



Membrane RoofingMonolithic membrane roofs are an excellent option for flat or low-slope roofs. Modern membrane roof products are quite durable and have a reasonably long service life. Any flat or low slope roofing material is subject to large amounts of expansion and contraction as well as a large exposure to ultra-violet degradation. For these reasons an annual inspection of all membrane roofs is recommended. Problem areas tend to be seams, flashings, curbs and parapets.

Steel RoofingSteel roofing is gaining popularity in many areas of the country. Steel roofing is the most durable roofing option. Steel has a long service life (50 year minimum), but is expensive and more difficult to install.11 Steel roof panels can be installed with nails or screws and rubber washers. The highest quality steel roof installation method is called standing seam and must be done by a steel roofing professional. Steel offers color options that are not available with any other roofing options. Steel roofs are not problem free, however. Steel tends to amplify the sound of rain and hail and can be annoying to occupants. Steel can be permanently dented and disfigured by hail. The most significant problem with steel roofs in northern climates is snow and ice slide-offs.12 Such slide-offs can result in building damage and pose a potential risk to occupants on the ground. This situation can be remedied by the installation of snow guards or cleats fastened in a fixed pattern to the surface of the roof.

Wood ShinglesWood-shingled roofs were the roof of choice on homes built until the early 20th century. They typically consisted of Cedar sawn shingles or Cedar split shake shingles. Wood shingles have a service life of 20-40 years, but are also much more expensive to purchase and install than asphalt shingles. Wood shingles are also more durable and less subject to storm damage than asphalt shingles. It is critical that wood shingled roofs be allowed to dry out thoroughly following rain events. On heavily shaded sites, the north side of wood shingled roofs may not dry completely, and this situation can foster the growth of moss on the roof. This condition is easily remedied by placing a base copper wire along the length of the north side of the roof just below the ridgeline. Rainwater washing over the wire creates a chemical that kills the moss and better allows the wood shingles to dry.

Siding

Aluminum/SteelAluminum and steel siding are very durable siding products with a long service life. These siding products are susceptible to denting from windstorms and hail. They are also subject to paint wear and fading. These siding products can be repainted and, if properly maintained, can provide an indefinite service life. If the siding is removed, it should be recycled.

Fiber CementFiber cement siding is a very durable siding option with a long service life if properly maintained. Like most building products, fiber cement siding needs to be allowed to dry following wetting events. If fiber cement siding is consistently wet for long periods of time, it will deteriorate. Fiber cement siding cannot be buried in the ground. Please refer to manufacturer’s installation literature.

VinylVinyl siding is manufactured from Poly Vinyl Chloride (PVC). PVC produces very durable products for some applications, but its manufacturing process involves carcinogenic products and produces waste that is dangerous to the environment and disposal of PVC products is problematic. PVC is also vulnerable to ultra-violet degradation and damage from hail and wind-blown debris and PVC has a very high coefficient of expansion (COE).15 These properties make PVC siding a less desirable choice than other siding products.



Wood Lap/Plywood/Wood Shingle/Composite WoodAll wood siding is naturally durable if properly maintained. Wood was wet while it was being grown, and wood can handle being wet frequently as long as it can dry out between wetting events. In new construction, all wood sidings should be installed with an airspace behind them to allow for drying. Damage prevention strategies include effective overhangs, paint or other finishing products, proper flashing, and appropriate caulking and sealing. If wood siding products are protected and allowed to dry after wetting events, they will provide a very long service life.

SkylightsFixed glass skylights are problematic in northern climates because of building movement, high levels of annual rainfall and the potential for interior condensation. Skylights should be checked annually (spring) for flashing or glazing problems. Skylights in northern climates can also experience condensation problems that can lead to cosmetic and structural deterioration.

Storm DoorsStorm doors are installed to provide an additional barrier to weather events. Storm doors should be inspected annually to assure that the latch is securely pulling the door against the weather-stripping. The latch should be adjusted to assure a tight seal against the weather-stripping. Damaged weather-stripping should be replaced.

Storm WindowsTraditional wood storm windows that are installed and removed seasonally need to be annually inspected for paint and screen damage. If repaired and stored properly, wood storm windows should be serviceable for decades.

Metal combination storm windows are relatively maintenance free. Damaged screens or broken glass panes should be repaired.

Stucco

Synthetic StuccoSynthetic stucco, commonly known as EIFS (Exterior Insulation and Finish System) is a moderately durable cladding. EIFS is installed over a polystyrene insulation substrate. EIFS is highly susceptible to puncture damage and water damage as a result of inadequate flashing. A positive aspect of EIFS cladding is that it can easily be colored to match other building elements, and can be shaped into unlimited decorative elements. If not properly flashed, however, EIFS cladding can deteriorate very rapidly.

Traditional Three-Coat StuccoTraditional stucco cladding is very durable and has an indefinite service life if properly maintained. If stucco becomes damaged or if remodeling or other repairs are required, it is very difficult for an inexperienced craftsman to repair traditional stucco. It is advisable to enlist the services of a professional plasterer to make such repairs.

WindowsWindows provide essential daylighting and ventilation functions in homes. Windows are also the most problematic elements of the building envelope in terms of energy loss and air leakage. Operable windows should be inspected on an annual basis. Such inspections should include:

- Observe the interior and exterior of the window. Look for signs of water leakage or condensation damage. Exterior water leakage must be addressed immediately. Determine the source of the leak. Insure functioning overhang, effective flashing, or sealant replacement. Interior condensation damage on wood windows can be merely cosmetic, or can be



structural. Cosmetic damage can usually be repaired by properly refinishing the interior of the window sash and frame. Structural damage may require sash replacement or entire window replacement. If structural damage is apparent, contact a qualified window installer to discuss options. It is important to address interior humidity levels to minimize future condensation damage.- Check the latching hardware and hinges for proper operation. Replace any damaged hardware. Make sure windows latch tightly against weather-stripping.

- Inspect all weather-stripping. Look for damaged or loose weather-stripping. Also, occasionally the weather-stripping can shrink, leaving gaps for potential air and/or water leaks. Re-install loose weather-stripping and replace any that is damaged or shrunken.

- Clean exterior and interior of window glass semi-annually in the spring and autumn.

- Drapes and shades can help reduce glare, fading, overheating and nighttime heat loss. Insulated drapes or movable insulation panels can further reduce heat loss during nighttime hours. Drapes and shades have the potential for increasing condensation on windows by partially isolating the window from normal interior convective airflows. This allows the window surface to become cooler and more prone to condensation. Also, lowering the temperature between the shade and the window raises the relative humidity, which also increases the condensation potential. Drapes and shades that contact the floor and are enclosed in a valance at the top are much less likely to contribute to the condensation problem and will further reduce heat loss through the window on cold nights.

- Movable solid insulation panels are very effective at reducing nighttime heat loss through windows, but the panels must be properly fitted and weather-stripped in order to completely isolate the window from the interior space.

- Drapes, shades and movable insulation panels should be closed in the evening when daylighting is no longer effective. Likewise, they should be opened as soon as daylighting is effective in the morning.

- glazing Replacement:Many energy efficient houses utilize different glazing types on different facades of the structure. In the event that a sash or its glazing need to be replaced, it is important to replace the unit with the same or an equally performing glazing material. Proper record keeping will allow you to identify the proper glazing for the window needing repair.17

Double HungDouble hung windows were designed to facilitate natural ventilation by providing a way to exhaust hot air through the top sash and draw in cool air through the lower sash. Homes with double hung windows should employ them for natural ventilation.



HeaTInG, VenTILaTIOn, & aIr COndITIOnInG (HVaC) SYSTemS

Air Source Heat PumpsAnnual inspection by an HVAC professional is recommended (spring). Clean outdoor condensing unit with garden hose. Turn off the unit with the service disconnect switch (usually mounted on the device or right next to it on the house) prior to cleaning.

Central Air ConditionersAnnual inspection by an HVAC professional is recommended (spring). Clean outdoor condensing unit with garden hose. Turn off the unit with the service disconnect switch (usually mounted on the device or right next to it on the house) prior to cleaning.

DehumidifiersDehumidifiers should be thoroughly cleaned annually. Unplug prior to cleaning. A general rule of thumb in Iowa is that winter interior humidity levels should not exceed 45%. An inexpensive hygrometer can be purchased to monitor the level. Excessive window condensation when outdoor temperatures range from 0-20 degrees F is also a good indicator of excessive interior moisture levels. Dehumidification may be required if high humidity levels are present.23

Ductwork SystemsAs mentioned above, all ductwork should be sealed with duct mastic or mastic tape. Ductwork can also be sealed from the inside by a duct sealing professional. In retrofit situations, duct cleaning is desirable. A one-time duct cleaning followed by regular filter replacement will help insure good indoor air quality. All ductwork in unconditioned space must be insulated to R-8 although a higher R-value is desirable.21 In both new construction and retrofit situations, ductwork systems should be pressure tested and balanced by an HVAC professional.

Electric BoilersElectric boilers do not require the same inspections as gas boilers, but having the element resistance checked by a professional every 2-3 years is desirable22 as sediment build-up on the heating elements can greatly reduce the efficiency of the boiler.

FurnacesFurnaces are complicated mechanical devices that require annual inspection and tune-up by a professional. This is best done in the summer when the service professional can also check the operation of the air conditioning system. In both new and retrofit situations it is highly recommended that the homeowner have a performance testing and system balancing performed to insure that the system is adequately delivering the conditioned air to the living space. All ductwork joints should be sealed with duct mastic or mastic tape. All ductwork in unconditioned space must be insulated to a minimum R-8 (more is better).19 Inspect intake and exhaust piping in the fall and clear any obstructions. Furnace filter(s) should be replaced monthly as needed. Be sure to replace the filter(s) with the same or slightly higher MERV (Minimum Efficiency Reporting Value) rating. High efficiency filters may actually cause excessive wear on the furnace blower, as it was not designed for such high resistance to airflow.20

Gas BoilersBoilers, like furnaces, need annual inspection and tune-up by a boiler professional. Homeowners can visually inspect the boiler and distribution piping for any signs of leaking or corrosion.



Geothermal Heat PumpsAnnual inspection by an HVAC professional is recommended (spring).

HumidifiersHumidifier elements can experience sediment build-up and may require cleaning. Perform the cleaning prior to the heating season. Humidifier elements are inexpensive and are easily replaced if necessary.

Mini-Split Air ConditionersAnnual inspection by an HVAC professional is recommended (spring). Clean outdoor condensing unit with garden hose, making sure to turn the power off.

Safety AlarmsSmoke Alarms: It is recommended that all homes have a smoke alarm installed on each living level of the home and in each bedroom.

Carbon Monoxide Detectors: If combustion appliances exist in the home, a carbon monoxide detector should be installed on each living level of the home. The basement alarm should be installed near the furnace/water heater area.

Static Air CleanersStatic air cleaners may require periodic cleaning or maintenance. Refer to the owner’s manual for instructions regarding the performance of these operations.

ThermostatsAll HVAC systems can benefit from the installation of a programmable thermostat. Programmable thermostats allow homeowners to adjust the operation of their heating and cooling systems to meet their specific lifestyle requirements. This results in both comfort and reduced energy costs. Homeowners should read and become familiar with the programming process. This will allow you to make adjustments in your program without having to rely on an HVAC professional.

Window Air ConditionersClean filters monthly throughout the summer. Clean condenser coils with a garden hose every spring prior to use, making sure to turn the power off.

Bathroom Exhaust FansBathroom exhaust fans are critical in reducing interior moisture build-up in homes without Heat Recovery Ventilators (HRVs), but they are often installed poorly and, therefore, cannot perform to their potential. Typically, bathroom exhaust fans have small, low-CFM blowers that require short, smooth ductwork to operate properly (always make sure that the exhaust fan vents outside and never directly into the attic). Flexible plastic ductwork or metal ductwork with large lengths and numerous elbows can make fans ineffective. Ductwork in unconditioned space must be insulated to prevent condensation. Depending upon the installation, bathroom exhaust fans often move much less air than their rated capacity. By controlling the exhaust fan with a timer rather than a wall switch, you can adjust the run time to help assure that residual showering and bathing moisture is exhausted.

Gas Metergas meters should be kept free of tall grass, plants or shrubs. The meter needs to ventilate occasionally and should have good air movement around it.

HRV/ERV (Heat Recovery Ventilator/Energy Recovery Ventilator)HRV and ERV maintenance is relatively simple. The unit core should be cleaned every six months. The intake and exhaust ports should be inspected periodically for obstructions and must be kept clear of snow during the winter. Many Heat Recovery Ventilators (HRVs) are operated with a time control switch. As with radon ventilation fans, the goal is to provide adequate ventilation with minimal unit operation time. The interior humidity level is a good indicator of adequate ventilation. Interior humidity levels should not exceed 45%.26 An inexpensive hygrometer can be used to monitor interior humidity levels. Another indicator is moisture condensation on windows. The HRV should be operated at a rate that greatly reduces or eliminates window condensation. Adjust the unit run time until the proper humidity level is maintained.

Kitchen Range HoodsKitchen range hoods are of two types, vented (to the outside) and recirculating. Both types employ grease filters in order to capture grease and particulates. In vented range hoods, it is critical to regularly clean the grease filters to prevent grease from entering exhaust ductwork where it can condense and create a potential fire risk. Recirculating range hoods rely on a grease filter to capture grease and particulates and a carbon filter to capture odors. The grease filter must be cleaned periodically depending upon build-up. The carbon filter should be replaced annually.

Whole-House Exhaust FansWhole-house exhaust fans can be very effective in reducing cooling costs, but they are very problematic in that they also present a significant air and moisture leakage problem during the northern heating season. Any summer cooling savings are sacrificed proportionally during the heating season. If a whole-house fan exists in your home, great care should be taken to weatherize the fan opening with an insulated and tightly sealed access panel/door.



Radon Ventilation FansThe operation of a radon ventilation fan depends on the tested radon level within the home. The current recommended safe threshold level is less than 4 pCi/L of radon.24 The goal is to provide adequate radon reduction with minimal fan operation. Radon ventilation fans should be placed on an adjustable time control. A tested level of 4-7 may be remedied by periodic fan operation (Example: On 30 Min./Off 30 min. or On 20 min./Off 40min.). Higher tested levels may require continuous fan operation.25 Since every situation is unique, the only way to determine what strategy is most effective is by trial and error. Try a fan operation strategy and then re-test. Then make adjustments and re-test until the optimum operation strategy is realized.



PLUmbInG

BathtubsBathtubs often have inaccessible drain traps, so removal of hair, etc., from the drain screen reduces the potential for a clogged drain and the need for drain cleaning products or professional drain cleaning. Bathtub caulk should be checked once per year for adhesion and structural integrity. Failed caulking can allow water to enter the walls around the bathtub, creating the potential for structural deterioration or mold and mildew growth.

BidetsBidets are an excellent alternative to a complete shower or bath. Bidets are effective for both females and males. Bidets use a fraction of the water of a shower or bath. Bidets that are not used regularly have the potential to have their drain traps dry out and permit sewer gas to enter the home similar to a floor drain. The problem is remedied by running a small amount of water down the bidet’s drain.

Clothes Washer FaucetIf the clothes washer supply faucets are left open at all times, the potential for a broken hose while the home is unoccupied exists. This can result in catastrophic damage especially if the clothes washer is installed above finished space. A simple solution is to close the faucets when the washer is not in use. Several manufacturers offer a faucet with a single lever handle that turns off both the hot and cold supply lines with one simple action (much like a light switch).

Condensate PumpsCondensate pumps, which are often installed on furnaces and other appliances, can plug or cease operation and may create a wet area on the basement floor that may not be obviously related to the condensate pump. If you suspect a condensate pump is not operating, an HVAC professional or a plumber should be contacted.

Drains and TrapsMany clogged drain problems are the result of build-up in the trap below the sink. Cleaning these traps is simple and well within the capability of most homeowners. Use a large pair of channel-lock pliers to loosen the nuts, remove the trap, clean and replace. Care should be taken on older metal fittings as they can be easily damaged and require replacement. Repair of the trap will eliminate the need for caustic polluting drain cleaners.

Exterior HydrantsExterior hydrants are predominantly used during the spring, summer, and fall when humidity levels are often high. Condensation on the hydrants’ waterlines can be a significant contributor to residual interior moisture. Insulating the hydrant supply lines with pipe insulation (R-3 to R-4) eliminates this problem.

Another potential problem with exterior hydrants is the backflow of caustic chemicals from plant fertilizer and pesticide applicators attached to garden hoses (alternative pest and fertilizer options are encouraged). Unless the exterior hydrant is equipped with a backflow preventer, the potential exists for pollutants to be drawn into the fresh water system within the home. new exterior hydrants should all be equipped with backflow preventers. In retrofit situations, it is recommended never to leave chemical applicators connected to a hose when not being used. All replacement exterior hydrants should be equipped with backflow preventers.



Faucets/FixturesAll faucets should have their aerators cleaned every 6 months. Flow restrictors should be installed in all existing faucets. All new faucets should be low-flow. The following flow rates are recommended: Shower: 1.5 gallons/minute, Lavatory/Utility: 1 gallon/minute, Kitchen Sink: 1-1.5 gallons/minute.

Floor DrainsFloor drains often sit unused for long periods of time. This can allow the water in the drain trap to evaporate and allow sewer gasses to enter the home. If you smell sewer gas, it is most likely coming from a floor drain with a dry trap. Simply pour a pint of water in all unused floor drains every 1-2 months to prevent this problem. nOTE: If sewer gas is present during the winter, and filling the floor drain does not stop the odor, the plumbing vent pipe on the roof has most likely frozen shut and will need to be opened to eliminate the odor.

Hot Tubs/SpasLike whirlpool bathtubs, hot tubs and spas are required to be protected by a gFCI (ground Fault Circuit Interrupter) receptacle or circuit breaker. These receptacles or circuit breakers should be tested by pressing the test button every three months. If the test is not successful, do not use the hot tub or spa until an electrician is contacted to remedy the problem.

Lavatory/Kitchen/Utility SinksAll sinks have the potential for leaking around their rims or at the junction of the countertop or sink top and the walls. Often these leaks are small and are not readily detected, but they contribute to the residual moisture in the home and increase the potential for structural deterioration or mold and mildew growth. Periodic replacement of caulking and rim sealants eliminate this problem.

Main Water Valve Homeowners should locate the home’s main water valve and operate it so that they are familiar with its operation should they need to turn the water off in the event of an emergency.

Rainwater CollectionRainwater collection or “harvesting” is common in areas of the U.S. and the rest of the world where central water systems cannot supply adequate water or where central systems do not exist. Rainwater collection is simple and has several economic and environmental benefits. Collected rainwater can be used to flush toilets, wash clothes and feed exterior hydrants and irrigation systems after simple filtration. After purification it becomes potable and can be used for any purpose.

Rainwater collection also retains rainwater runoff on the site, which is environmentally beneficial. Rainwater collection can be as simple as running downspouts into a rain barrel and then re-using the collected water for plant watering, irrigation, etc. A more complex system directs water into a buried cistern from which it can be pumped for use in toilets, clothes washers and exterior hydrants/irrigation systems. (Sizing rainwater collection systems depends on geographical location, roof collection area and rainwater re-use requirements. There are many online resources that can help you calculate your rainwater system.) A first flush device ($50-100) that removes most of the roof debris during the first few minutes of the rain event is essential.31 A submersible pump and a shallow well pressure system deliver the water as if it were from a central system. Overflow water from the cistern can be directed to a raingarden. Although experimental, rainwater has the potential to provide radiant cooling in homes with hydronic heating systems.

Septic SystemAs a general rule, septic systems work properly for many years without any maintenance. Problems can arise, however. Most problems are related to the materials flushed into the tank, or the effectiveness of the leach field to infiltrate and evaporate effluent.



Septic systems rely on the natural action of bacteria and enzymes to decompose waste solids leaving a liquid effluent, which is dispersed through a distribution box and the leach field. Typically septic tanks have two compartments. The first compartment is where the primary decomposition process occurs. The second compartment contains less solids and completes the decomposition process.

Septic systems are very sensitive to the products flushed into them. Caustic chemicals such as paint thinner, pesticides, motor oil, certain cleaning fluids and drain cleaners, etc., should not be flushed into septic systems, as they can kill the bacteria and stop the decomposition process. This results in a build-up of solids what will eventually plug the system and require pumping the tank and re-starting the decomposition process. Occasionally the stoppage requires excavating the tank and/or distribution box for cleaning.

Another potential problem is flushing large quantities of vegetable waste into a septic system. Plant material is more difficult to breakdown and can build up, eventually requiring pumping of the tank. Small amounts of vegetable waste from a garbage disposal are acceptable, but most vegetable wastes should be composted or disposed of in another manner. The periodic addition of purchased enzymes (Rid-X, etc.) can help assure that the decomposition process is working properly.

Another problem with septic systems is the flushing of solids such as tampons, etc. These products do not decompose in a septic system and tend to collect in the distribution box or in the leach lines plugging them and causing the septic tank to back up into the home. This situation requires excavation to repair and is very expensive and destructive to the yard. Dispose of these items in a different manner.

Some solids may build up in septic systems and may require pumping every several years. If the toilet flushing action becomes slow and sluggish, that is an indicator that the tank should be pumped by a septic system professional.

Sewage EjectorsA sewage ejector is a type of pump that is designed to pump solid materials into a sewer. If you suspect a problem with a sewage ejector, contact a plumber for repair.

ShowersLike bathtubs, showers also often have inaccessible drain traps, so preventing drain-plugging materials from entering the drain can greatly reduce potential clogging products. Also, failed caulking, tile grout, etc. can allow water to enter the surrounding walls creating a potential for structural deterioration or mold and mildew growth.

Sump PumpsSump pumps are often essential to prevent subsurface water from entering basements, etc. In areas where high subsurface water is a regular occurrence, it is highly advisable to have a sump pump with a battery back-up system that will assure that the pump will continue to operate during an electrical power outage.

Sump pump wells or pits have the potential for silt or sand build-up and should be checked after each high water event and cleaned as required.

Another common problem with sump pumps is that they often sit idle for long periods of time (months or even years) before they are needed to operate during a rare high water event. Sump pumps spend their life in a high moisture environment and, if not operated regularly, can rust, corrode or seize up so that they cannot operate properly when called upon to do so. Sump pumps in this situation should be manually operated 3-4 times per year to assure their proper operation when required.27



ToiletsFederal law requires that all toilets sold in the U.S. must use 1.6 gPF (gallons per flush) or less. If an older toilet with a 5 gPF rate still exists in a home, it should be changed. The water savings will rapidly pay for the new toilet. An even better option is to replace any single flush toilet with a dual flush toilet that offers a 0.8-0.9 gPF option for liquids and a 1.28-1.6 gPF option for solids. The incremental cost difference is modest and the life cycle savings in water use are huge.

UrinalsUrinals typically use 0.2-0.4 gPF and can result in significant water savings, especially in families with several male members.

Vent PipingThe primary problem that occurs with plumbing vent piping is the vent outlet freezing shut during very cold periods during the winter. This can cause a build-up of sewer gas in the home. The problem can be solved by breaking or melting the ice from the vent opening. If the problem persists, the size of the vent outlet pipe needs to be increased to 4”.28 The larger pipe size is much less likely to freeze closed.

Water Heaters

Gas/Electric Tank-Type Water HeatersWater heaters may require periodic maintenance depending upon the mineral content of the water. First of all, water heater temperature should be reduced to 125 degrees F. Most water heaters are pre-set to 140-150 degrees F. This temperature is not necessary for any household activities, and can pose a scalding risk. In addition, keeping hot water at higher than necessary temperatures is expensive and energy wasteful. You can check the water heater temperature with a common kitchen thermometer and reduce the setting accordingly.

Older water heaters can benefit from the addition of a water heater insulation blanket, which will reduce energy loss from the tank.

If the mineral content of the water is high, a build-up of condensed minerals can occur in water heater tanks. Most water heaters include an anode rod whose function is to collect mineral deposits. If you know that you have a high mineral content in your water, the anode rod should be checked annually and replaced if necessary. Also, annual flushing of the tank by draining and re-filling will remove the condensed mineral deposits that build-up on the bottom of the tank. If such build-up is not removed, it can greatly reduce the efficiency of the water heater. Gas/Electric Tankless Water HeatersTankless water heaters work on the principle of heating a small volume of water very rapidly. This requires much higher temperatures at the gas-fired heat exchanger or electric heating element. Higher temperatures can result in greater build-up of mineral deposits on the heat exchanger or heating element. This condition can rapidly reduce the efficiency of the heater, and may require regular replacement of the heat exchanger or heating element. The output temperature should be set to 125 degrees F.

Water PipingBoth hot and cold water lines can benefit from the addition of pipe insulation (R-3 to R-4). Insulating hot water lines saves energy and reduces the wait time for hot water. Insulating cold water lines also saves energy and reduces or eliminates the potential for condensation. Pipe insulation should be carefully fitted and glued or taped at all joints with the appropriate products. Manufacturers for each type of pipe insulation recommend a specific type of glue or tape to



use with their product. Pex plumbing can be insulated the same way as other types of water piping. Be sure to separate the hot and cold pipes from each other – do not bundle them together.

Whirlpool BathtubsWhirlpool bathtub electrical circuits are required to be protected by a gFCI receptacle or circuit breaker. These receptacles or circuit breakers should be tested by pressing the test button every three months.30 If the test is not successful, do not use the bathtub until an electrician is contacted to remedy the problem.

eLeCTrICaL

AFCI Circuit BreakersAFCI (Arc Fault Circuit Interrupter) circuit breakers must be tested periodically according to the manufacturers’ instructions.

Circuit OverloadingOverloading electrical circuits presents a significant fire hazard. Increasing the fuse or breaker amperage size will allow more electrical current to pass through undersized wire, which can increase heat build-up and potentially trigger a fire. The safer solution is to move some devices to other circuits. Household extension cords typically have much smaller wire than the wire installed in the home. Excessive loads on extension cords also pose a significant fire hazard. As Americans continue to add new electrical devices to their homes, the fire risk from older electrical systems increases. In retrofit situations, it is recommended that the electrical service entrance be upgraded to a 100 Amp minimum. 150-200 Amp is preferred.34

Electrical MeterThe electrical meter should be periodically visually inspected to verify that the meter seal and glass cover are intact.

Electricity Usage MonitorsElectrical usage monitors are useful in determining the power consumption of appliances and devices and can help a homeowner reduce their power usage. Monitors that check one appliance at a time can be purchased for $30-50. By plugging the monitor in and then plugging the appliance into the monitor the homeowner can see the current usage, the current cost per day, the projected cost for the month, etc.

Whole-house electricity usage monitors are tied to the electrical system and monitor total electrical usage. Some models identify each appliance in the home and provide continuous monitoring of their use. This information is then graphed on a computer so that the homeowner can see when they use the appliance and for what period of time. Most models also allow the homeowner to project energy cost savings based on the altered use of various appliances. These monitors are very effective at identifying the conservation and cost saving opportunities that are available in every home. Quality whole-house electricity usage monitors can be purchased for $150-300 and have many additional features not mentioned here.37

GFCI ReceptaclesgFCI (ground Fault Circuit Interrupter) receptacles must be tested periodically according to the manufacturers’ instructions.

GroundingProper grounding is essential for a safe electrical system. Lightning and surge protection devices are only as effective as the grounding system they are connected to. Households are rapidly becoming more electronic and digital.32 Electronic equipment is very sensitive to lightning strikes and power surges. Utility studies have shown that most residential grounding systems are not optimally effective. Many utilities require two ground rods placed a minimum of six feet apart and tied together in order to increase the grounding potential of the system. grounding systems are required to have a maximum electrical resistance of 25 Ohms. Most utilities will test your grounding system upon request. The addition of a second ground rod may be advisable.33



Lightning protection and surge protection devices are relatively inexpensive. If your system does not have this protection, it is highly recommended that you have them installed. Some insurance companies provide these devices free of charge, as they reduce their risk resulting from a surge event.

Landscape LightingLandscape lighting is an attractive addition to the exterior of a home, but can constitute a significant energy expense if used regularly. Many manufacturers offer solar powered landscape lighting that charges batteries during the day and powers the lights in the evening.

LightingIn 2012, conventional incandescent light bulbs will be phased out of the U.S. market. Only bulbs that have an improved efficiency of 25-30% will be available. CFL (compact fluorescent light), LED (light emitting diode) and others will be the only light bulb choices available.35 FixturesIn anticipation of the 2012 change, manufacturers are producing a wider variety lighting fixtures that have the fluorescent transformers installed in the fixture so that the bulb does not have to have an integral transformer. These bulbs are less expensive and reduce the environmental consequences of CFL disposal. Lamps (Bulbs)CFL lamps typically use 75% less energy to provide the same amount of light as an incandescent bulb. Changing all incandescent lamps to CFL lamps will return the investment in a matter of months and provide significant savings going forward. CFL lamps can last 4-5 times as long as incandescent lamps, but that life can be shortened by frequently turning the lamp on and off.

The general rule of thumb is the 15-minute rule – if you are going to be gone from a room for longer than 15 minutes, turn the lights off. If you are returning within 15 minutes, leave them on as this decreases the wear and tear on the CFL bulb and extends its life.

LED lamps are much more expensive than CFL lamps, but they last 2-3 times longer and generate almost no heat. As the price of LED lamps declines, they will become a more practical and cost effective option.

Lightning Protection SystemComplete home lightning protection systems are less common today than in times past, but considering the potential damage that lightning strikes pose to a home, it is an option worth considering. Contrary to popular belief, the function of a lightning protection system is not to attract and ground lightning strikes but rather to dissipate the electrical charge that builds up in the earth during a thunderstorm. This greatly reduces the potential for a lightning strike.

An economical alternative to a complete lightning protection system is the installation of a lighting arrestor on the home’s electrical system. Lightning arrestors need to be installed by an electrician.

Overhead ServiceAn overhead electrical service (power lines) can be damaged by high winds or other storm damage (falling trees, etc.). Following major weather events the overhead service should be visually inspected to make sure that the wire is not damaged and that the mast is intact and is securely fastened to the building. Any irregularities should be reported to the electrical utility provider.



Phantom LoadsIn 2009, phantom electrical loads accounted for 10% of all the electricity used in the U.S.36 Phantom electrical loads are those numerous small loads that homes have operating 24/7. Any appliance that has a remote control is using energy even when it is off so that it can respond to the remote control when required. All rechargeable devices utilize a transformer that reduces the utility voltage to the voltage amount required by the device. (Cell phones, laptops, electric toothbrushes, cordless shavers, cordless vacuums, etc.). The transformers used to charge these devices are using energy when they are plugged in whether or not the device is being charged, wasting energy and money.

Phantom loads can be eliminated by unplugging or turning off charging transformers and remotely operated devices. This can be done by having transformers plugged into a common outlet strip that can be turned off when it is not required. In new construction, switched circuits can be installed to control phantom loads. Such circuits can be controlled by an occupancy sensor that automatically turns the circuit off when occupants leave the room.

Security LightingExterior security lighting on urban homes should be controlled by a motion sensor and checked periodically for proper function. In rural locations, utilities offer security lighting for a fixed monthly fee. These lights tend to be large with high lumen output and may be required in locations where a large area must be illuminated. If large area coverage is not required, it may be advisable to eliminate the utility provided security light and rely on house mounted CFL fixtures on motion sensors.

Service Entrance PanelThe electrical service entrance panel should only be accessed by an electrician. All electrical service panels must have a cover to prevent accidental contact with energized terminals within the panel. Inspect the panel cover to assure that all unused circuit breaker openings are covered with a protective plug. If all circuits are not listed on the service entrance panel cover, the circuits should be identified and recorded on the panel cover. This can aid in future repairs.

Smoke/Fire AlarmsSmoke and fire alarms should be tested regularly in accordance with manufacturers’ instructions. Low batteries should be replaced immediately.

Switches and ControlsElectricity is the most easily controlled of all energy sources. Timers, motion sensors, occupancy sensors, humidistats, dehumidistats, thermostats, solid state dimmers, photoelectric switches, etc. are a few examples of electrical switches and controls that can be used to reduce electrical usage, increase occupant comfort, modify behavior, and improve the home’s durability.

Underground ServiceOccasionally, underground service wires can become exposed due to earth settling or washout from a heavy rain event. Exposed wires pose a significant safety hazard and should be re-buried immediately by a professional. PVC conduit housing service entrance wires can be damaged by mowers and other power equipment. Most utilities are responsible for all equipment from their transformer to your meter. The homeowner is responsible for all equipment from the meter into the building. An electrician will be required to repair or replace any damaged equipment that is the homeowner’s responsibility.

Appliances offer homeowners the greatest opportunity for energy saving by purchasing energy efficient appliances and then operating them in the most efficient manner. Much of this section was adapted from the Iowa Energy Center’s Home Series Book Four: Major Home Appliances. Refer to the Iowa Energy Center website, www.energy.iastate.edu, for more information.

Clothes Dryersnew clothes dryers offer various energy efficiency features. As with all appliances, homeowners must read the owner’s manual and familiarize themselves with the appliance’s features and proper operation. All appliance owner’s manuals should be retained for future reference. Flexible plastic or flexible metal foil dryer vent hoses can collapse or crush thus allowing them to trap lint and create a fire hazard and are, therefore, not recommended by manufacturers. Only rigid or flexible metal ducts should be used. Significant energy savings can be realized from both new and existing clothes dryers by using the following usage strategies:

- Set dry time according to the type and size of the load.- Avoid overloading the dryer to allow for air circulation and water evaporation.- Separate and shake bulky items before you load them.- Use the moisture sensor if your dryer has one, to avoid over-drying clothes.- Use the cool-down cycle to utilize the residual heat and reduce clothes wrinkling.- Clean the lint screen after every load to enable the dryer to properly vent moisture.- Check and clean the outside clothes dryer vent monthly.- Regularly clean the moisture sensor near the drum to maintain effectiveness.

Clothes Washersnew clothes washers offer many energy and water-saving features. As with all appliances, homeowners must read the owner’s manual and familiarize themselves with the appliance’s features and proper operation. All appliance owner’s manuals should be retained for future reference. The energy efficiency and water efficiency of clothes washers are rated by their Modified Energy Factor (MEF) and their Water Factor (WF). A minimum desirable MEF is 1.72. A minimum desirable WF is 8.0. Significant energy and water savings can be realized from both new and existing clothes washers by using the following usage strategies:

- Wash full loads whenever possible.- Use the lowest water volume setting possible for the load being washed.- Use cold water with a cold-water detergent.- Use easily biodegradable detergent.- Use the right amount of detergent.- Choose a cold-water rinse.- Select an extended spin cycle to reduce more expensive drying time.



DishwashersMany people believe that hand washing of dishes uses much less energy than a dishwasher. In fact, an energy efficient dishwasher can save 5,000 gallons of water and $40 per year in electricity costs over hand washing. new dishwashers offer many energy efficiency features. Dishwashers are rated by their Energy Factor (EF). A new dishwasher should have an EF of .65 or higher. As with all appliances, homeowners must read the owner’s manual and familiarize themselves with the appliance’s features and proper operation. All appliance Owner’s Manuals should be retained for future reference. Significant energy savings can be realized from existing dishwashers as well through proper operation. A few operation tips are:

- Scrape but don’t rinse dishes unless food is dried on, burned-on, or extremely greasy.- Arrange loads so that all dishes are exposed to cleaning and rinse water.- Run only full loads.- Set your dishwasher to air-dry.- Clean the filter regularly.- Occasionally clean the spray-arm nozzles and water jets.

Microwave OvensMicrowave oven can use 80% less energy to do the same cooking job as a conventional range, oven or cooktop. A microwave for use in cooking whole meals should have a capacity of 1.5-2.0 cu. ft. and an energy usage of 1000 Watts or larger.

Ranges, Ovens, CooktopsRanges and ovens are low maintenance appliances and many offer few energy saving features, but some recent models do offer timing and other features that can reduce energy use.

GasIt is important to keep burners clean, and observe the flame for proper combustion. A blue flame indicates proper combustion. A yellow flame indicates that the burners need to be adjusted by an appliance professional. Periodically inspect the oven door gasket for crushed or damaged spots and replace if necessary. As with all appliances, it is recommended that homeowners read the operator’s manual and become completely familiar with the appliance’s various features. All appliance manuals should be retained for future reference.

ElectricHeating elements should be kept clean, as build-up can reduce the heating efficiency and extend required cooking time. Periodically inspect the oven door gasket for crushed or damaged spots and replace if necessary. As with all appliances, it is recommended that homeowners read the operator’s manual and become completely familiar with the appliance’s various features. All appliance manuals should be retained for future reference.

Saving energy using kitchen ranges and ovensWhile it is important to properly clean and maintain kitchen ranges and cooktops, the greatest energy savings can be realized through slight modifications in cooking methods such as:

- Using only as much water as necessary when boiling foods.- Choosing pots and pans that match the size of the burner.- Using the smallest pot, pan or baking dish for the portion you are cooking.- Using flat bottom cookware for the greatest heat transfer from an electric range or cooktop.



- Using lids on pots and pans to retain heat, allowing foods to cook faster and more efficiently. - Keeping cooktops and drip pans clean.- Limiting preheating time to 10 minutes.

Refrigerators, Freezers and IcemakersRefrigerators, freezers and icemakers should be placed on dedicated electrical circuits to reduce the potential of a circuit overload that can result in the power being interrupted to the appliance and food being spoiled. These appliances should never be operated with a household extension cord. When purchasing a new refrigerator, freezer or icemaker, compare the cost, features and the Energyguide label. This will allow you to compare features, energy usage and cost in order to make the best decision for you.

As with most modern appliances, refrigerators, freezers and icemakers offer many convenience and energy saving features. Read the owner’s manual and familiarize yourself with the appliance’s features. The owner’s manual should be retained for future reference.

Periodically check the refrigerator and freezer temperature settings and adjust to the manufacturer’s suggestion. Refrigerators should generally be set between 36-40 degrees F. Freezers should be set no lower than 0 degrees F.

Refrigerator and freezer door gaskets should be inspected periodically for crushing or breakage. The gasket’s sealing integrity can be tested by placing a piece of paper behind the gasket and closing the door. If the paper falls out or is easily pulled out, the gasket is not sealing properly. Damaged gaskets should be replaced.

Trash CompactorsAs with all appliances, homeowners must read the owner’s manual and familiarize themselves with the appliance’s features and proper operation. All appliance owner’s manuals should be retained for future reference.

Wine and Beverage CoolersUnlike conventional and compact refrigerators, countertop, under-counter, and freestanding wine and beverage cooling appliances aren’t required to show an Energyguide label, and none have been qualified by Energy Star. Depending on what they will be storing, these coolers include an adjustable thermostat and generally operate within a narrow temperature range of about 38-65 degrees F.

You can still, however, make an energy-smart choice when buying one of these units. Look for a cooler that uses a thermoelectric or Peltier cooling system which is a small, solid-state heat pump that is much more efficient than a conventional compressor. In addition, choose a unit with an external temperature control and digital display as well as LED lighting instead of a heat-producing incandescent light bulb.

Blower DoorIn new construction, a pressurization/depressurization (blower door) test can be performed prior to the drywall installation in order to identify any air leaks and seal them. In retrofit situations, a blower door test can identify air leakage areas in need of repair. Blower door tests may be offered by utility companies as part of their energy audit process. Home energy raters can also be employed to perform the tests.

Carbon Monoxide TestingEconomical carbon monoxide monitors and test kits are available at most hardware stores. All homes with combustion appliances should have carbon monoxide monitors near the furnace, water heater, other combustion appliances and near the entrance from an attached garage.

HVAC System Testing/BalancingThe rated efficiency of a furnace or air conditioning unit represents the tested efficiency under factory conditions. The actual installed efficiency of an entire HVAC installation is often only 50-60% of the rated unit efficiency. The length, size, and configuration of the ductwork system can significantly affect the overall performance of the installed system. Competent HVAC installers should perform pressure, temperature, and combustion tests and adjust the system so that it delivers a minimum of 90% of its rated capacity to the home. Unfortunately, many installers are not trained in these procedures and, therefore, most systems do not operate at peak efficiency. The purchase of a new HVAC system should include a guarantee that the system will perform to the 90% level. In retrofit situations, independent testing firms can be employed to perform the tests and make adjustments.

Infra-Red ScanningInfrared scanning cameras identify areas of heat loss in a building envelope. Infrared cameras are useful in identifying energy losses, water leaks and air leakage areas. Infrared scanning may be offered by local utilities as part of their energy audit process, but home energy raters may also be able to provide infrared analysis.

Lead & AsbestosLead and asbestos testing is available free of charge through most local municipalities. All homes built prior to 1970 should be tested and, if high levels are discovered, appropriate mitigation strategies should be employed.

Moisture TestingMoisture testing equipment can be used to identify water leaks and potential mold producing conditions. Moisture testing can be performed by cleaning professionals, home inspectors and home energy raters.

Radon TestingRadon test packets are inexpensive and the tests can easily be performed by homeowners. In a newly constructed home, the tests should be performed six months to one year following the completion of the home. In existing homes the tests can be performed at any time. It is recommended that a test be performed on the lowest, regularly occupied level of your home. The EPA recommends fixing, or mitigating, your home if test results show radon levels of 4 or more picocuries of radon per liter (pCi/L). Mitigation involves strategies that provide ventilation from beneath the basement floor slab or the sump pump well ducted to the outside. Following the implementation of a radon mitigation system, the home should be re-tested and adjustments made until the tested level drops below 4.38
