RATIONALE, BENEFITS, AND INTENTIONS

The goal of this chapter is to produce a healthy indoor environment by keeping contaminants and pollutants out of

the interior. Provisions are included that affect the HVAC system installation, limiting sources of indoor air

pollutants from entering the building during construction and post-occupancy.

The IAQ Management Plan (Plan) is a written plan that demonstrates the procedures that will be used and

precautions that will be taken to safeguard indoor air quality during the construction of the building. The Plan will

include procedures for implementing the operation and maintenance of the building and its systems for the

completed buildings, for protecting the duct system during construction, for safely venting specific gas and solid

fuel fireplaces and appliances, and for ensuring that specific prohibited materials are not used in the building.

The Plan will cover the following topics and provide procedures for the following:

HVAC Systems. A plan for protecting the HVAC system, including ducts, must be included to ensure that

the system is protected from contamination from particulates and to ensure that the occupants are

protected during construction.

Ventilation. A plan for providing outside air for construction workers must be included in the Plan. This air

can be provided through either mechanical or natural ventilation.

Prohibited Materials. The Plan will specify specific materials will not be allowed to be used in the project.

BEST PRACTICES AND INNOVATIONS

ASHRAE’s Indoor Air Quality Guide: Best Practices for Design, Construction and Commissioning1 identifies five

critical strategies to managing the design and construction process to achieve good indoor air quality. Each of

these strategies should be addressed in the Plan:

1. Integrate design approach and solutions – as mentioned elsewhere in this User’s Manual, integrated

design is critical to sustainable buildings. Indoor air quality solutions are multi-disciplinary and should be

addressed as such.

2. Commission to ensure IAQ goals are met – include this plan and in the Commissioning plan (as required in

Chapter 9 of the DCGCC) guidance on commissioning as a quality control process for IAQ.

3. Select HVAC Systems to improve IAQ and reduce energy impacts of ventilation – as noted above the HVAC

system requirements and setting will differ between construction phase and occupancy.

4. Employ project scheduling and mange construction activities to facilitate good IAQ – the project schedule

must accommodate proper IAQ procedures

5. Facilitate effective operations and maintenance – addresses the interaction between the design team and

operations and maintenance team to ensure the system operates and provides benefits as intended.

For complete guidance in best practices refer to ASHRAE’S Indoor Air Quality Guide: Best Practices for Design,

Construction and Commissioning.

802 BUILDING CONSTRUCTION FEATURES,

OPERATIONS + MAINTENANCE FACILITATION

KEY REQUIREMENTS

Design HVAC systems and the spaces where they are located to ensure that ducts, air handling units, fans,

coils, and condensate plates are accessible for cleaning and repair

Design HVAC systems to ensure that airflow does not bypass filter racks and that the access panels have

flexible seals to eliminate air leakage around the filter rack


D E S I G N Coordinate HVAC design across disciplines to ensure that simple access is provided to air

handling system, and that filter racks are designed to facilitate a tight fit around filters.

P E R M I T T I N G Provide information in mechanical plans to verify access ports, panels and/or doors are

not obstructed.

I N S P E C T I O N S Verify the HVAC system has been installed based on the approved plans at rough in and

final inspections.




Implement maintenance according to manufacturer’s specification and in accordance

with the Plan, including cleaning of ducts, fans, coils, heat exhchangers, drain pans and

the replacement and maintenance of filters.

Consider post occupancy-system commissioning to ensure the system retains optimal

functionality


The air inside our buildings can be 2 to 5 times more polluted than the outside air due to the presence of

particulates and various chemical compounds. Significant amounts of dust and particulates are generated on

construction sites and unless actions to mitigate those pollutants, they will become entrained throughout the

mechanical system. Once entrained, they will be blown out into the building over time where they can cause

problems for people with allergies or respiratory problems.2

Chapter 8 | 5

The OSHA requirements for Indoor Air Quality in Commercial and Institutional Buildings provide a checklist for

ensuring that the HVAC system, including the filtration systems, is operating properly. The checklist contains

requirements for scheduled cleaning and maintenance for portions of the system that are in direct contact with

the airstream, such as humidifiers, cooling coils, duct and plenum equipment, and filtration systems.

Dust particles can harbor pollens from plants, microbes, and other contaminants that can become allergens if

inhaled. Other airborne pathogens are also present in duct systems that can be minimized by providing the proper

quantity of outside air and an efficient filtration system for recirculated air.3 Ensuring that the HVAC system is

designed to prevent airflow from bypassing filter racks and also providing unobstructed access to parts of the

HVAC system that must be periodically cleaned will help reduce indoor air quality issues.


Advanced air filtration: ASHRAE provides recommendations for removing contaminants through air filtration

systems. The goal is to reduce occupant exposure to a variety of contaminants and improve occupant health,

comfort, and productivity. ASHRAE Standard 52.2, Table 802 provides the recommendations for filter efficiency

based on the objective for the filter. Filter efficiency is designated a MERV value (Minimum Efficiency Reporting

Value) with high number being more effective at cleaning air than lower values.

Ensure access to filter banks: Filter banks can be located in several locations based on performance, access, and

lifecycle cost.4 Filter racks and filter systems are essential for ensuring good IAQ in the building. It is important that

no air is allowed to bypass the filter system. This can be achieved by the design and selection of filter systems that

allow the filters to fit tightly into racks to minimize leakage around them. The duct system coils and heat exchanger

surfaces can remain clean for long periods of time with an effective filter system. This will reduce particulate

matter being transported to spaces in the building through the air system. Section 802 also requires that the doors

used to access the filters do not allow air to leak between the filter system and the doors themselves when they

are closed.

803 HVAC SYSTEMS

KEY REQUIREMENTS

Duct openings must be protected during the construction process to keep contaminants from entering

the duct system

Temporary ventilation systems are required during construction for those working at the building site

Ductless systems or ducted systems using a MERV 8 or higher filter must be used if the space is

conditioned during construction


D E S I G N Include construction phase in indoor air quality management plan.

P E R M I T T I N G

Provide information on which ventilation strategy will be used during construction.

Note on mechanical plans that HVAC openings will be protected during dust-producing

operations, and filters will be replaced prior to building occupancy.

I N S P E C T I O N S Verify the Plan has been followed to verify that the HVAC system is protected



P O S T O C C U P A N C Y ===


Dust and airborne particulates impact both the health of the building occupant and the efficiency of the HVAC

system. Dust can collect on coils and heat exchangers in mechanical systems and reduce the heat and cool transfer

to the air, resulting in a reduction in efficiency. Inhaling particulates can potentially cause lung cancer, asthma, and

cardiovascular problems. Operating the permanent HVAC system during the construction of the building can

introduce moisture, dirt, and debris into the system, which can be prevented by sealing and protecting the duct

openings during construction. The provisions in Section 803 focus on maintaining good air quality by protecting

the HVAC system during construction and also exhausting dust and airborne particulates. The stipulations in

Section 803 do allow the system to operate if the return air filters are replaced prior the building being flushed and

to building occupancy. During construction, ASHRAE Standard 62.1 prohibits running a HVAC system that uses

Chapter 8 | 7

particle filters unless the particle filters are in place.


Planning. Green Code Pro recommends the development of a duct and equipment protection plan that can be

included as part of the IAQ Management Plan. The duct and equipment protection plan would describe the

methods to be used to protect the ductwork during construction to meet the provisions of Section 803. In

addition, Green Code Pro recommends the following practice to protect the HVAC system:

“HVAC Protection: Ensure that dust and construction debris does not accumulate in HVAC ducts. Measures could

include wrapping HVAC ducts and equipment in plastic. Ductwork and equipment should be stored in dry and dust

free areas prior to installation.” 5

Conditioning during construction: If the space is to be conditioned during construction, either a ductless heating

and cooling system or a ducted system with a MERV 8 filter or higher can be used. Temporary ductless systems can

be used for both heating and cooling the space. Portable systems are available for use on site until the building is

to a point where the HVAC system can be started.

ASHRAE recommends that the building site be kept at correctly tempered conditions to allow for proper

construction procedures. “If the construction environment [is kept] at the proper conditions for cleanliness,

temperature, and humidity, workers will be more productive, construction materials (adhesives, paints, drywall,

etc.) will perform as specified, the quality of construction will be improved, and the IAQ for the project will be

improved.”6

Outside air during construction: It is important to provide outside air during construction. Three options are

provided for meeting this requirement.

1. Provide natural ventilation in accordance with the International Mechanical Code. Buildings with low

(greater than or equal to 4% of the floor area in glazing for each space) to moderate window area will

typically meet this requirement prior to the installation of the fenestration.

2. Use fans that produce a minimum of three air changes per hour. The following calculation can be used to

determine the fan size:

(Volume of the Building (ft3) / 60 minutes/hr) X 3 air changes/hr = required cfm of fan.

3. Install an exhaust system for the building or space that is rated at a greater cfm than the supply air serving

the space. This will put the space under negative pressure and will exhaust airborne contaminants instead

of pressurizing the space and pushing the contaminants into adjacent spaces in the building.

805 PROHIBITED MATERIALS

KEY REQUIREMENTS

Asbestos-containing materials are prohibited from use in the project

Urea-formaldehyde foam insulation is prohibited from use in the project


D E S I G N Research material selections to ensure materials are not specified.

P E R M I T T I N G Provide notes on restrictions in drawings.

I N S P E C T I O N S Verify that the products installed are those identified on the plans and specifications

Section 805 prohibits the use of materials that are known human carcinogens or irritants that can cause health issues

including asbestos and urea-formaldehyde. Asbestos has been classified as a known human carcinogen by the U.S.

Department of Health and Human Services, the EPA, and the International Agency for Research on Cancer. Studies have

shown that exposure to asbestos may increase the risk of lung cancer and mesothelioma.7

Asbestos has been used for the following in buildings:

Attic and wall insulation containing vermiculite

Vinyl floor tiles and the backing on vinyl sheet flooring and adhesives

Roofing and siding shingles

Textured paint and patching compounds used on wall and ceilings

Chapter 8 | 11

Walls and floors around wood-burning stoves protected with asbestos paper, millboard, or cement sheets

Hot water and steam pipes coated with asbestos material or covered with an asbestos blanket or tape8

There are several restrictions on the use of asbestos in products including flooring felt, rollboard, and corrugated,

commercial, or specialty paper. Asbestos is also banned in products that have not historically contained asbestos.9

Section 805 prohibits any product containing asbestos from being used in the project.

Urea-formaldehyde foam insulation (UFFI) was used extensively in the 1970s. Homeowners used UFFI as wall

cavity filler at the time in order to conserve energy. In the 1980s, concerns began to develop about formaldehyde

vapor emitted in the curing process as well as during the breakdown of old foam. Emission rates exceeding 3.0-5.0

parts per million (ppm) cause a variety of adverse health effects impacting the eyes, nose, and respiratory system.

Consequently, its use was discontinued. UFFI was usually mixed at the location while constructing the home’s

walls. It was then injected inside the walls and underwent the curing process prior to acting as an insulating agent.

Because less information was known about the toxic health effects of formaldehyde in the 1970s, extra

formaldehyde was often added to the mixture to ensure that the curing process would occur completely. Since the

UFFI was not a well-sealed product [open-celled foam], any excess formaldehyde in the insulation would off-gas

into the home's living space. The early UFFI materials were also affected by moisture and heat, which compounded

the off-gassing concerns since rising temperatures, caused residuals of formaldehyde contained in the insulation to

be released and migrate into indoor air10.

Urea-formaldehyde foam insulation was used in homes in the 1970s. Formaldehyde present in the air at levels higher than

0.1 parts per million (ppm), can cause the following health effects11:

Watery eyes

Burning sensations in the eyes, nose, and throat

Coughing

Wheezing

Nausea

Skin irritation

The intention of this section is not to require the removal of these materials if lawfully in existence in the building

at the time of installation. There are many benefits, risks and costs to weigh along with federal laws on removal of

hazardous materials that should be considered if a project is found to contain asbestos or urea-formaldehyde and

the owner chooses to remediate.

806 MATERIAL EMISSIONS + POLLUTANT

CONTROL

KEY REQUIREMENTS

Composite wood products used inside the approved weather covering of the building must not exceed

the formaldehyde emission limit.

Adhesives, sealants, architectural paints, and coatings used in buildings must not exceed the VOC

emission limits as stated in Chapter 7 of DCMR Title 20 (Environment)

At least 85% of the flooring installed in the building must not exceed the maximum VOC emissions limit

At least 85% of the acoustical tile sealing and wall systems installed in the building must not exceed the

maximum VOC emission limit


D E S I G N Research and select products that do not exceed the designated VOC limits.

P E R M I T T I N G Specify products in drawings and specifications that do not exceed the designated VOC

limits.

I N S P E C T I O N S Verify that the products installed are those identified on the plans and specifications


O C C U P A N C Y

Records for materials used in project should be kept throughout the construction

process and made available as requested prior to Certificate of Occupancy


Ensure maintenance procedures prohibit adhesives, sealants, architectural paints, and

coatings that exceed the VOC emission limits as stated in Chapter 7 of DCMR Title 20

(Environment) and purchasing and requisition processes prohibit materials exceeding

formaldehyde emission limits.


Formaldehyde is a chemical used in the manufacture of building materials. Formaldehyde is also a by-product of

the combustion of fossil fuels and certain other natural processes. Formaldehyde may be present both inside and

outside the building. The intent of this provision is to limit the quantity of formaldehyde introduced inside the

building through building products, and also to limit other VOCs that are introduced in the building from other

products.

Chapter 8 | 14

Volatile organic compounds (VOCs) are emitted as gases from certain solids or liquids. VOCs include a variety of

chemicals, some of which may have short- and long-term adverse health effects. Concentrations of many VOCs are

consistently higher indoors (up to ten times higher) than outdoors. VOCs are emitted by a wide array of products

numbering in the thousands. Examples include: paints and lacquers, paint strippers, cleaning supplies, pesticides,

building materials and furnishings, office equipment such as copiers and printers, correction fluids and carbonless

copy paper, graphics and craft materials including glues and adhesives, permanent markers, and photographic

solutions. The goal of this section is to limit the amount of formaldehyde and other VOC emissions that are

brought in through building materials. Composite wood products that use adhesives free from urea-formaldehyde

are preferred. These products are produced under specific standards and use other types of resins that are derived

from fossil fuels. Products that are sealed with an impermeable sealant on all surfaces are also favorable. On these

products, a polyurethane coating is typically applied to reduce emissions. It is important to note that the emissions

for the products are tested at the point of manufacture and not at the building site, so documentation will need to

be provided for each product that falls under the requirements to demonstrate that it does not exceed the

maximum levels.

Furniture and other fixtures use composite wood that can also emit formaldehyde. These products are exempted

from this requirement primarily because they are not considered permanent and therefore cannot be monitored.

Adhesives, sealants, architectural paints, and coatings all emit VOCs and are therefore regulated by the Title 20 of

DCMR (Environment) for Volatile Organic Compounds and Hazardous Air Pollutants. Each product most be tested

at the point of manufacture to ensure that it does not exceed the maximum limit of VOCs emitted.

Flooring and acoustical ceiling tiles and wall systems that use formaldehyde or other products that emit VOCs are

also regulated by this requirement and must not exceed the maximum VOC levels specified. There are several

products that are considered organic and do not emit VOCs such as gypsum board, concrete, metal and gypsum

plaster. These can be used on floor, wall, and ceiling systems without testing.


Flooring/Ceiling/Walls: Install 100% of the flooring, ceiling, or walls in one of the following low VOC materials to

meet the VOC limits of Table 806.4(2): ceramic and concrete tiles; clay pavers; concrete; concrete pavers; metal;

organic-free, mineral-based materials

Reduce total VOC: Adhesives and sealants, architectural paints and coatings, flooring, acoustical ceiling tiles, and

wall systems and insulation shall have a Total Volatile Organic Compounds (TVOCs) emission limit of ≤ 500 ug/m³.

Further VOC reductions may be eligible for electives in Appendix A, Sections A108.2, A108.3, and A108.4 and

A108.5.
