INTRODUCTION

Together with the assistance of alliancePROJECT, the City of Anaheim’s sustainability initiative, Anaheim Business Energy Efficiency Solutions (ABEES) is pleased to provide you with this Comprehensive Energy Audit Report at no cost to you. Since 1894, Anaheim Public Utilities (APU) has served the City of Anaheim with low rates and reliable service. Today, Anaheim businesses continue to enjoy low electric rates while being served by one of Orange County’s top-rated electric utilities. APU ABEES, in conjunction with the alliancePROJECT team, is providing recognized engineering excellence to our APU customers and setting a standard of energy efficiency.

Your decision to participate in Anaheim Public Utilities’ ABEES program is a first step toward better control of your energy costs. We hope you make use of this study to develop a comprehensive energy plan for your facility. Concerns with operating costs and environmental issues have prompted many companies to take a second look when purchasing new equipment and implementing operating practices. Improving a building’s energy efficiency is one way to reduce the “Environmental Impact” of the total operation as well as to improve the facility’s “bottom line.” You can consider this report as a ‘Road-Map’ specific to ABC Company, leading you to a more energy-efficient facility, lower environmental impact, and lower utility costs.

UNDERSTANDING INCENTIVE PROGRAMS

APU’s ABEES provides a series of available incentives, “Business Solutions Program,” for particular energy efficiency upgrades conducted by our customers.

Who Can Benefit

Benefits are designed to fit the needs and requirements of all Anaheim Public Utilities commercial, industrial, or institutional electricity customers.

Program Advantages

Financial Savings – In addition to electric cost savings, the program provides funding to assist you in the installation or upgrade to energy-efficient HVAC equipment. Incentives are dependent upon each measure as reduced kW demand or kWh.

Customized Energy Incentives - By upgrading to energy-efficient equipment and processes, energy use will decrease, in turn decreasing electric costs. On average, customers save ten to twenty-five percent (10-25%) on their bill with energy-efficient applications.




YOUR COMPREHENSIVE ENERGY AUDIT REPORT (CEAR)

This CEAR is intended to provide ABC Company with an analysis of the energy-using systems at your facility, and to recommend measures to help you use energy more wisely and efficiently. The CEAR includes information needed to apply for and process incentives, as well as other benefits that are part of the aggregated “Business Solutions Program.”

The alliancePROJECT team of trained energy professionals performed a thorough on-site audit of all your energy-using equipment. The audit includes data collected from: lighting, heating, air conditioning, refrigeration (HVAC&R), and other miscellaneous electrical equipment. Our representatives gathered information on energy consumption (i.e., manufacturer specifications), hours of operation, capacities, and operating & load factors. alliancePROJECT also obtained and reviewed your facility’s utility bills from most recent twelve (12) months and conducted a rate analysis study.

alliancePROJECT used the data obtained during the on-site inspection to develop a comprehensive computer model of your facility’s energy use. From this model, we determined a “base case scenario” representing the total energy loads from all the various points of usage (lighting, cooling, etc.). The model was then benchmarked to match actual energy usage. The benchmarked energy model of the facility was used to calculate an estimate for future energy use. Analyses performed with this model allowed for specifying which strategies can be used to optimize energy efficiency, and which Energy Efficiency Measures (EEMs) were applicable for ABC Company

This report contains the results and details of the efficiency measures recommended. We included Operation & Maintenance EEMs, Short-Term EEMs, and Long-Term EEMs for each of the specified ABEES programs. Each EEM was evaluated for estimated energy operating cost savings, estimated installation cost, projected Simple Payback Period, and anticipated incentive amount. EEMs were then evaluated for other parameters that could impact the ultimate implementation of the EEM including but not limited to: future expansion capability, regulatory compliance & permitting, cost of maintenance, and incentive reimbursements, etc.

ANALYSIS METHODOLOGY

Energy Efficiency Measures (EEMs) were evaluated using the California Energy Commission (CEC) methodology as described in the CEC Technical Assistance report guidelines and ASHRAE Level 2 assessment goals. CEC guidelines require that all Operation and Maintenance (O&M) items be implemented before evaluating measures requiring capital expenditure. After O&M items are implemented, measures are evaluated in the following order:

Note: When using the savings methodology approach for the replacement of any unit, the energy savings are derived by comparing the existing unit’s efficiency rating with the new unit’s efficiency rating.

Each measure was analyzed for estimated savings and estimated costs. When estimating the installed costs, prices were obtained from vendors, recent past projects, and estimating tables. As recommended in the CEC Technical Assistance report guidelines, the measure cost estimates also include: sales taxes, demolition/disposal, engineering/project management, permits, and an inflation factor. We feel that this makes the Payback estimates for these measures rather conservative.

EXECUTIVE SUMMARY

ABC Company is located at 123 Anaheim Blvd. The total estimated area is 50,000ft2 that includes 35,000ft2 Air Conditioned area, 15,000ft2 Out Door Area. alliancePROJECT energy professionals performed a Comprehensive Energy Audit to determine energy efficiency projects to lower their energy by utilizing more energy efficient equipment. Data collected includes an inventory of all equipment, equipment nameplates, building operation schedules, equipment operating hours, and the utility bill history obtained from APU. All energy-using systems were analyzed and evaluated for energy consumption and proper operation by utilizing alliancePROJECT’s Energy Modeling Software. A list of applicable potential Energy Efficiency Measures (EEMs) was created and then evaluated for both cost effectiveness and impact on facility operations. For each EEM requiring a capital investment, a Simple Payback of capital cost divided by annual savings was calculated.

ENERGY CONSUMPTION ANALYSIS

ABC Company maximum billing demand that was determined from their electric account is 145kW from March, 2018 to February, 2019. alliancePROJECT’s Energy Modeling Software Analysis breaks down energy usage percentage by type of equipment. The monthly demand for each equipment type is shown in Table 1.

TABLE 1: kW BREAKDOWN




Energy Efficiency Measures

Energy Efficiency Measure (EEM) recommendations have been broken down into three main categories.

Operation & Maintenance (O&M) EEMs can be accomplished with little or no capital expense; e.g. perform required equipment maintenance, equipment repairs, frequent tune-ups on a regular basis, and/or change operating schemes or time schedules to accurately reflect occupancy and energy requirements. Accurate and efficient O&M policies and systems will help increase the life of your equipment and produce better efficiency.

Short Term EEMs are projects that do not require a great deal of permitting, planning, or engineering design to be implemented. They have a short (5 years or less, per industry standards) Simple Payback and can easily be performed at your facility. Such projects include: lighting retrofit, replacement of older inefficient units with more energy efficient models, etc. These projects require a licensed contractor to perform installations.

Long Term EEMs are projects that require permitting, planning, design, drawings, permit submittals, construction management, and/or start-up services. They have a longer (greater than 5 years, per industry standards) Simple Payback. For Long Term EEMs, we recommend that either an outside engineering consultant or in-house engineer be retained to provide the necessary documentation to complete these detailed and involved measures.

Recommended Program Incentive Projects*

The following general APU ABEES Program incentives are recommended for ABC Company.

*Different aspects of the same project may fall under multiple EEM categories, e.g. Short Term, LongTerm, or O&M. In order to quantify capital investment requirements, Tables 2 and 2.1 categorize each specific EEM in this way. However, for ease of understanding the various energy incentive programs and projects, EEM recommendations are organized below under their specific Program titles.

LIGHTING PROJECTS INCENTIVES may include the replacement of standard Fluorescent lightingsystems, High Intensity Discharge (HID), or Incandescent lamps with new generation Fluorescent,LED, or Induction lamp technologies, etc.

CUSTOMIZED ENERGY PROJECTS INCENTIVES are implemented for replacement of several energysystems such as: older motors with new NEMA rated energy-efficiency motors, adding variablefrequency drive controls, new air compressors, envelope insulation, injection molding machines,energy management controls, or HVAC&R replacements.

Using the industry standards as a guideline, systems need regular maintenance, and aging units should be replaced.

ASHRAE also published “cooling load index” check figures. The values are as follows:

Low: 360 ft2 / Ton

Average: 280-ft2 / Ton

High: 190-ft2 / Ton

ABC Company has an estimated conditioned area of 16,798 ft2. The total space cooling and heating system for the regularly occupied areas has a capacity of 58.5-Tons. The cooling load index for ABC Company is 287 ft2/Ton. If this facility was designed today it would have Average expected load index.




OPERATIONS & MAINTENANCE EEM RECOMMENDATIONS

The following O&M recommendations can immediately be implemented at your facility to: 1) reduce cost and energy, 2) increase equipment life, and 3) reduce energy demand without any major capital investment.

RECOMMEND

For all HVAC units, clean evaporative and condensing coils. Replace air filters every three months which results in better air flow and increases efficiency, and schedule for replacing old units. Estimated energy savings is between 3% - 8% for most HVAC systems.

RECOMMEND

Verify refrigerant levels in your air conditioning system. Low refrigerant levels negatively impact energy efficiency and cooling capacity. For example, a system with an 85% charge has 25% less efficiency than a properly charged system.

RECOMMEND

Verify the programmed schedule and temperature set-points regularly to maintain acceptable occupancy comfort. It is recommended to start cooling when it reaches a maximum temperature of 74°F and start heating when it drops to a minimum temperature of 68°F.

LIGHTING EEM RECOMMENDATIONS

Lighting Retrofit

This audit combines an aggressive approach for de-lamping in some areas, with a more conservative “1-for-1” replacement approach in other areas. A 1-for-1 lamp replacement is recommended in areas where lighting illumination levels are critical, such as labs, test areas, design/drafting rooms, etc. However, it is always recommended that an illumination calculation is made prior to actual retrofitting to ensure that the required illumination foot-candles is not compromised beyond acceptable Illumination Engineering Society (IES) and Code levels.

Studies have shown that more efficient lighting also results in decreased replacement costs due to longer lamp and ballast lifespans, reduction in heat gain (which results in lower area cooling demand), and overall improvements to occupant comfort and productivity.

Every effort was made to accurately obtain a lighting fixture count to be used for analysis in this report. However, the worksheets are intended to be an estimation of lighting energy use, and not a fixture-by-fixture inventory.

RECOMMEND

Replace all interior and exterior non-LED lighting with new LED fixtures or bulbs.




CUSTOMIZED EEM RECOMMENDATIONS

Motion Detectors

Motion detectors, or occupancy sensors, provide efficient lighting control and save energy costs by turning off lights remain in unoccupied spaces. A conservative average savings estimate was calculated at a rate of 35% after installation of these units. (It is noted in the lighting worksheet where some areas have an existing “E” or “x” if a motion sensor is recommended.)

RECOMMEND

Install motion detector, or occupancy sensors, for lighting control in offices, common areas, closets, storage areas, restrooms and conference areas. For open areas it is recommended installing ceiling motions sensor.

Note: Lighting contractors will identify the number of units needed to provide greatest energy savings.

NEXT STEPS

RECOMMEND

Consult with a bonded, licensed mechanical contractor to perform HVAC maintenance and upgrades in accordance with the enclosed recommendations contained herein.

RECOMMEND

Consult with a bonded, licensed lighting contractor to perform lighting retrofits and upgrades in accordance with the enclosed recommendations contained herein, including occupancy and dimming sensor control system.

Apply for all available APU ABEES incentives for the measures described above (see Application details and contact information in the Appendix).

DESCRIPTIONS OF ENERGY EFFICIENCY MEASURES

OPERATIONS & MAINTENANCE (O&M)

RECOMMEND

For all HVAC units that are not replaced, it is highly recommended to clean evaporative and condensing coils, and maintain full refrigerant levels. Clean/repair ductwork systems and replace air filters every three months, as it results in approximately 8% minimum-gain efficiency. If the operation and maintenance measures are not regularly implemented, the performance of the HVAC ductwork system and other equipment will degrade with time due to deposit build-up and overall lower energy efficiency of the system.

LIGHTING

RECOMMEND

Upgrade existing lighting in accordance with Table 6: Lighting Audit worksheet.

Luminance

All foot-candles from any fixture installed must meet Uniform Building Code and/or National Electrical Code requirements in accordance with IES Lighting Handbook 2011 Application Volume. Retrofit of any critical area such as operating rooms, emergency, examination rooms, labs, drafting areas, machinery production areas, etc. that involve installation of reflectors (excludes 1-for-1 bulb replacements) should have attached accompanying calculations signed by a Registered Electrical Engineer showing room retrofitted illumination meets IES Code if required by Plan Check. If illumination prior to installation of retrofit does not meet code, additional light sources must be added until the space complies with IES Code.

Light-Emitting Diode

Light-emitting diode (LED) is a semiconductor light source. LEDs are used as indicator lamps in many devices and are increasingly used for general lighting. Appearing as practical electronic components in 1962, early LEDs emitted low-intensity red light, but modern versions are available across the visible, ultraviolet, and infrared wavelengths, with very high brightness.

When a light-emitting diode is switched on, electrons are able to recombine with holes within the device, releasing energy in the form of photons. This effect is called electroluminescence, and the color of the light (corresponding to the energy of the photon) is determined by the energy band gap of the semiconductor. An LED is often small in area (less than 1mm2), and integrated optical components may be used to shape its radiation pattern. LEDs have many advantages over incandescent light sources including lower energy consumption, longer lifetime, improved physical robustness, smaller size, and faster switching. However, LEDs powerful enough for room lighting are relatively expensive, and require more precise current and heat management than compact fluorescent lamp sources of comparable output.

LIGHTING OCCUPANCY SENSORS

The most effective method of electricity reduction is to TURN OFF THE LIGHTS!!! Occupancy Sensors or Motion Detectors provide the ability to turn off unneeded lights. These devices use an infrared light beam to sense motion within a specified range and this will complete a relay circuit that turns on the lights. After a period of no movement in the area, the sensor breaks the circuit, thus turning off the lights.

Motion detectors are best suited to rest-rooms, offices, storage rooms, classrooms, and janitor areas. They are not generally suited for nurse’s stations, exam rooms, corridors, and surgeries. Sensing range is up to 60 feet with coverage of approximately 180°. Indoor and outdoor types are available. Note that the kWh savings must be compared not to the original base electric usage, but to the new, lower wattage, retrofitted light fixtures. As the retrofitted light fixtures use significantly less kW per fixture, motion detectors will have a reduced return on investment versus being used on non-retrofitted fixtures.

Recommendation(s)

1. Use motion detectors that are adjustable. Set the “No Motion” setting to five minutes and the“Stay On” setting to 10 minutes. If the “Stay On” setting is too short, the higher current draw ofthe energy efficient electronic ballasts will offset any savings.

Below is a simple savings calculation for a sample fixture:

Before Retrofit: 4 lamp 4 Foot F32 T8 Electric Fixture 110W x 500 hrs/yr saved by motion detector x 10-3 kW/W (conversion factor) = 55 kWh saved

After Retrofit: LED Fixture 50W x 500 hrs/yr saved by motion detector x 10-3 kW/W (conversion factor) = 25 kWh saved

QUALIFICATION

The conclusions and recommendations presented in this report are based on the results of the on-site inspection and initial energy audit that was performed at the subject property as well as the review of any drawings, equipment data, and/or utility bills provided. The results of the site investigation are necessarily limited to this specific location and are valid only for the specific time and conditions at which the inspection was performed.

In all cases, a standard of professional care used by comparable consultants performing similar tasks in similar localities was exercised in obtaining, reviewing, interpreting, and verifying all available information. Savings estimates were made as accurately as possible. However, as these figures depend on actual use and information given to us by the facility personnel during the site visit(s), and may vary considerably from month-to-month, the actual savings you receive could be different. The costs shown for installation are based on estimates using current unit costs for labor, equipment, and taxes.

Although every effort has been made to ensure accuracy, exact conditions will vary and you must obtain firm quotes before implementing these measures. The Simple Payback is defined as the capital cost divided by the annual savings. Simple Paybacks have been calculated before taxes for each measure requiring a capital investment. Since the annual savings and capital costs can vary, these Simple Paybacks can also vary.
