1. OVERVIEW

A. EXECUTIVE SUMMARY This document presents a Technical Energy Audit prepared by Honeywell Building Solutions (HBS) for energy conservation measures at Elida High/Jr High School, Vocational Agricultural School, Gymnasium and Elida Elementary School. The energy audits are performed under Tasks #3 and #4 of the State of New Mexico Energy, Minerals, and Natural Resources Department (EMNDR) Contract No. 10-521-A073212-0302 for Regional Education Center #6. The purpose of this contract is to identify energy efficiency measures that can be implemented under the Energy Efficiency and Renewable Energy Bonding Act, NMSA 1978, 6-21D-1 et seq. also known as the Clean Energy Revenue Bond (CERB). For the preparation of this Technical Energy Audit, HBS conducted site surveys and reviewed design, operational, and utility information provided by Elida Municipal Schools staff to determine energy and water use and possible energy and water conservation opportunities. The following energy conservation measures (ECM’s) were evaluated for each building:

Energy Conservation Measures 1 Energy policy 2 Energy management system 3 Lighting retrofit with occupancy controls 4 Economizer retrofit to RTU's 5 Weatherization 6 Computer power management 7 Insulate domestic hot water tanks 8 Variable frequency drives 9 Vending machine setback 10 Building insulation 11 Freezer/cooler monitoring/modifications

See individual school section for detailed description of energy conservation measures.

This Technical Energy Audit is based on Honeywell’s best practices and procedures established through years of energy auditing and performance contracting experience. The audit and recommended energy conservation measures represent an accurate and comprehensive report and forms a solid basis for making decisions on implementing the measures included in this report.

• CONCLUSIONS AND RECOMMENDATIONS

A. GENERAL BUILDING AND HVAC DESCRIPTIONS Building: Elida Elementary School was built in 1949. It is a single story masonry building with six classrooms, a multi-purpose room, library and a computer lab. The building is approximately 14,400 square feet. Heating/Cooling/Ventilation System: Heating and cooling for the building will be supplied by combination rooftop air conditioning/gas heating units. Heating and cooling will be distributed by ductwork from rooftop package units. Fresh air will be supplied through outside air intakes on rooftop package units. The units are controlled by programmable thermostats that cycle the units on a call for either heating or cooling. During unoccupied periods the units cycle to maintain unoccupied setpoints. Lighting System: The predominant lighting fixtures are a mixture of four lamp and two lamp 32 watt T8 fluorescent with magnetic ballasts. Incandescent lights are used in the exterior. Average light level in the classrooms at desk height was 52 foot-candles. There are no automatic lighting controls.


02/04/11 Page 9

Building Envelope: The Elementary school is constructed with concrete masonry units (CMU), brick veneer and stucco exterior walls, steel roof deck and slab-on-grade foundation (originally constructed in 1949, with additions in 2002). The steel roof deck is supported by open web steel joists. The building is covered by a one-ply modified bitumen membrane. There are four aluminum-framed, double-glazed skylights above the main hallway. The wall finishes consist of drywall and large windows which are a combination of double-glazed-glass and aluminum frames. The exterior walls are clad with brick veneer and stucco and the exit doors are steel units. The windows are aluminum-framed, double-glazed units. The caulking around the windows and door frames is deteriorated

B. ANNUAL ENERGY USE Below is annual energy usage per utility broken out by end use.


02/04/11 Page 11

Energy Usage Base Year Data: Energy bills were provided by Elida Municipal Schools for two full years, starting with Jan 2008 and going through Nov 2009. These bills were normalized and a base year of Jan 2008 – Dec 2008 was selected. This is the most recent period for which full utility data was available when the technical energy audit began. In general, base year data does not differ appreciably from data for the preceding year. The base year provides a basis for performing energy end use analyses a) to understand how energy is used in a given building and b) to identify savings opportunities during the early stages of the energy audit. Projected energy unit savings are compared to base year energy consumption to ensure that the projected savings are reasonable. “Whole building” energy models were developed for the sites included in the Technical Energy Audit using eQUEST version 3.63, build 6510. The eQUEST program uses “typical meteorological year” (TMY2) weather files rather than weather data files for a particular year. Therefore, utility data for buildings modeled using eQUEST were averaged for a two to three year period (depending on availability of utility data) in order to calibrate the eQUEST models for those buildings properly. Potable water for Elida Municipal Schools is provided by the Town of Elida Water Company. The school district is billed a flat rate per water meter so any savings in water would not result in lower bills. For this reason potable water conservation measures were not evaluated. The annual energy use index (EUI) for Elida Elementary School is:

30,891 BTU/Square Foot. The annual energy cost per square foot for Elida Elementary School is:

$ 0.85/Square Foot.

Initial Savings and Investment Summary for Recommended Project:Elida Elementary School

Commercial rebates are not currently offered by either Roosevelt County Electric Cooperative or Conway Oil Company Association. Energy Conservation Measure Interactions Measure interaction effects have not been calculated since the intent of this study is to identify and prioritize energy savings opportunities. If multiple energy conservation measures are implemented total energy savings could be slightly reduced due to interactive effects depending on which combination of measures are implemented. Implementing lighting retrofits will reduce the heat generated by the lighting system. During the heating season the reduced heat produced by the lights will need to be replaced by the building heating system. During the cooling season the reduced heat produced by the lights will result in reduced energy needed to cool the space. The added heating costs will be roughly negated by the reduced cooling costs. Building weatherization/insulation/windows energy conservation measures will reduce both heating and cooling costs. These measures will reduce the savings attributed to the heating/cooling of the building since it will reduce the base load for the building. The energy conservation measures affected by weatherization/insulation/windows include the energy management system, economizer retrofits, as well as the heating/cooling equipment replacements.


02/04/11 Page 16

Variable frequency drives on supply fan motors will reduce the fan speed depending on the building load thereby reducing the heat generated by the fan. This results in reduced cooling costs during cooling season and increased heating costs during heating season. These load changes are negligible because of the size of the fan motors. Computer power management and indoor vending machine setback will have an effect on the building heating/cooling loads similar to the lighting retrofits, only on a much smaller scale. Insulating domestic hot water tanks will not influence the other loads in the building because most of the water heaters are located in areas that are not actively heated or cooled. Freezer/cooler savings measures will not influence the other loads in the building because most of the equipment is ventilated in areas that are not actively conditioned spaces.

EES1. Energy Policy:

Existing Conditions: The Elida Municipal School district works to manage its energy use. Most thermostats were set up correctly and teachers seem conscientious about turning off lights when leaving the classroom. The school currently has an energy policy that is not highly publicized or well known by members of the school community.

Proposed Upgrades: An active, dynamic Energy Policy is fundamental in order for the District to (a.) reduce the impact utility costs have on the budget, (b.) ensure that energy is used efficiently, and to (c.) maintain a reliable supply of energy to meet the functional needs of the District.

The school district should re-examine their current energy policy and review it to make sure it embraces all aspects of energy conservation. The update of this policy is the joint responsibility of board members, administrators, teachers, students and support personnel and its success is based on cooperation at all levels.

The energy policy should also be highly conspicuous and known to all stakeholders. Copies of the policy and energy conserving posters should be posted in public areas. The policy should be available on the district’s web site. A sample Energy Policy is included in the appendix. The Elida Municipal School District may wish to use this sample as a guide to modify/updating their existing policy. Savings Calculations: No additional savings were calculated for implementing an Energy Policy. Implementation Costs: An Energy Policy is developed and maintained by all stakeholders. The primary cost of implementation is the labor involved to review the policy and to make modifications to it. This work should be accomplished during the normal course of doing business and should not be an additional expense.

Operations and Maintenance: This measure is primarily an operations and maintenance activity. It is the summation of many small activities done by everyone involved in the school district.

EES3. Lighting Upgrades:

Existing Conditions: A lighting survey has been performed to evaluate the need for lighting efficiency upgrades.

Proposed Upgrades: The following table details the existing and proposed lighting system in this building. The Burn Hour Code references the table following this table and indicates the run hours for each lighting area. The Lighting Code indicates the type of new lighting. If the Lighting Code starts with an N then this indicates a new fixture and includes new ballasts. If the Lighting Code starts with an R then this indicates a retrofit fixture and includes new ballasts for fixtures using ballasts. The type of ballast is indicated by the last set of digits of the Lighting Code – LP for Low Power, SP for Standard Power, and HP for High Power Recommend the following lighting upgrades and occupancy sensors for the Elementary School:

Savings Calculations:

The following formulae were used to calculate the energy saving from the lighting upgrades:

1) Kilowatts (kW) Existing kW = pre-retrofit unit kW Proposed kW = post-retrofit unit kW Total Existing kW = Existing kW * Existing Qty * Global Diversity Total Proposed kW = Proposed kW * Proposed Qty * Global Diversity Total Saved kW = Total Existing kW – Total Proposed kW Total kW Dollars Saved = Total Saved kW * kW rate 2) Kilowatt-hours (kWh) Total Existing kWh = Total Existing kW * Hours of Operation Total Proposed kWh = Total Proposed kW * Hours of Operation Total Saved kWh = Total Existing kWh – Total Proposed kWh Total kWh Dollars Saved = Total Saved kWh * kWh rate 3) Total Dollars Saved Total Dollars Saved = Total kW Dollars Saved + Total kWh Dollars Saved + O&M Saved Global Diversity and Diversity Factor (DF) are the probability that a particular lighting fixture will be on at the time of the facility’s peak load. Savings Calculations Summary: The existing and proposed lighting system run hours from the hour tables above were reduced to 50% of the table values to match the lighting load with the utility bills: Upgraded Quantity of Luminaires 274Total kW Used (Existing System) with DF 16.70Total kW used (Existing System) without DF 22.63Total kW Used (Upgraded System) with DF 8.97Total kW used (Upgraded System) without DF 13.39Total kW Saved 7.73Total kW Saved - Max Potential 9.24Total kWh Used (Existing System) 29,539Total kWh Used (Upgraded System) 13,967Total kWh Saved 15,571Occupancy Sensor Savings Total kWh (Included in Totals 3,282Occupancy Sensor Savings (Included in Totals) $233Total Savings (Energy) $1,824HVAC Penalty or Savings $0Total Maint.

The life expectancy of the lighting upgrades depends on the type of fixture/bulb installed and the annual hours of usage of the lights. Below is a chart with typical life expectancy for different lighting components:

REFERENCE SOURCEEQUIPMENT USE CA CPUC WA ELCCA

(YEARS) 2010 2005(Curr)Lighting

Electronic ballasts 16 16 12Compact fluorescent 16 16 12Exit sign 16 16Fixtures HID 16 16 20Fixtures T8 16 16 20Lighting controls 16 16Occupancy sensors 10 10Time clock 10 8 10

Implementation Costs: The cost to remove the existing lighting system and install the new lighting system was figured using actual cost for the new bulbs, ballasts and fixtures and standard labor factors for their installation. Costs were figured by a lighting contractor who specializes in lighting upgrades. Operations and Maintenance: Operations and maintenance savings for the lighting retrofit are based on the difference between the existing lamp and ballast replacement rate and lamp and ballast replacement rate for the proposed upgrade. The first step is to calculate the Existing Average Annual Lamp Burn Outs (EAALB). This is the percentage of annual percentage of burned out lamps expected each year. It is calculated by dividing the annual hours of operation by the manufacturers stated lamp life, then multiplying by the number of lamps/ballast in each fixture.

Next, the Existing Average Annual Lamp Burn Outs percentage is multiplied by the Existing Estimated Lamp Purchase Cost (EELPC), giving us the Existing Estimated Lamp Replacement Cost (EELRC). This cost is assumed based on historical data.

The total annual cost of replacement lamps per fixture which is then multiplied by the Total Number of Existing Fixtures (TNEF) resulting in the Existing Total Lamp Replacement Material Cost (ETLRMC).


02/04/11 Page 23

The above equations are then repeated for the proposed lighting system. The difference between the Existing Total Lamp Replacement Material Cost and the Proposed Total Lamp Replacement Material Cost will yield the Total Lamp Material Savings (TLMS).

Similar calculations are repeated for ballasts. Labor costs are calculated for replacing the number of units defined by the above equations. It is assumed lamps will be changed by custodial staff and ballasts will be replaced by an electrician. The total lamp labor savings and total ballast labor savings are then added together to yield the Total Labor Savings (TLS).

Finally, the Total Labor Savings is added to the Total Material Savings to yield the Total Maintenance Savings.

Total Labor Savings = Total Labor Savings + Total Material Savings See Appendix for full set of equations.

Proposed Upgrades: Caulk all windows indoors and outdoors and replace weather stripping on all exterior doors. The caulking and weather stripping will reduce air leakage through the building envelope. Controlling air leakage is one of the most important functions of weatherization, and often the most difficult. The main goals of air leakage control are to: save energy, increase comfort, protect insulation’s thermal integrity, reduce direct cooling or heating of people and building components by outdoor air, and avoid moisture migration into building cavities.

The average useful life for caulking varies by type of caulking used. High-quality caulking compounds with a long life expectancy are generally more expensive, but end up being the most cost effective. Assuming that the caulking material is used outside as directed by the manufacturer, the following useful life may be expected: Silicone-30 years; polysulfides, polyurethanes, neoprene, acrylic, vulcanized butyl rubber-20 years; acrylic-latex, butyl rubber, and synthetic caulking compounds-8 to 10 years; cheaper caulking compounds-3 to 5 years. This energy conservation measure assumes the use of caulking with a 20 -30 year life expectancy.

Weather stripping comes in a variety shapes and sizes. Interlocking metal weather stripping is made of two V-strips that are placed on the door and the door frame. When the door closes, the two pieces interlock to make a tight seal. Interlocking pieces are placed completely around the perimeter of the door — on the top, both sides and the bottom. Tubular rubber and vinyl gaskets consist of small tubes of sponge rubber or vinyl also can be used to weather strip around doors and windows. When the door presses against the gasket, it forms a tight seal. By pressing against these gaskets, the door forms a seal. The type of weather stripping used depends on the condition and type of the existing door and frame. These two types of weather stripping have a life expectancy between five and eight years.

EES6. Computer Power Management: Existing Conditions: The existing computers in the classrooms and offices are turned on and off by the teachers or administrative staff. Some individuals turn their computers off daily and some leave them running.

Proposed Upgrades: Install free power management software by Verdiem that allows for scheduling standby modes. This software needs to be loaded on each computer and provides enhanced power management. Savings Calculations: The following formulae were used to calculate the energy saving from the computer power management:

1) Kilowatt-hours (kWh) Existing Existing Active Mode = 200 watts per PC/monitor combination Existing Standby Mode = 22 watts per PC/monitor combination Average Hours Per Week of Active Mode = 40 Average Hours per Week of Standby Mode = 56 Weeks per Year = 40 Total Existing Active kWh per PC/Monitor = Existing W * Hours/Week * Weeks/1000 = 320 Total Existing Standby kWh per PC/Monitor = Existing W * Hours/Week * Weeks/1000 = 49 Total Existing kWh per PC = Active kWh + Standby kWh =369 Total Existing kWh = # of PC/Monitors (34)* Total kWh/PC =12,546 2) Kilowatt-hours (kWh) Proposed Proposed Active Mode = 200 watts per PC/monitor combination Proposed Standby Mode = 22 watts per PC/monitor combination Average Hours Per Week of Active Mode = 32 Average Hours per Week of Standby Mode = 64 Weeks per Year = 40 Total Proposed Active kWh per PC/Monitor = Proposed W * Hours/Week * Weeks/1000 =256 Total Proposed Standby kWh per PC/Monitor = Proposed W * Hours/Week * Weeks/1000 = 56 Total Proposed kWh per PC = Active kWh + Standby kWh =312 Total Proposed kWh = # of PC/Monitors (34)* Total kWh/PC =10,608 3) Total Dollars Saved Total Dollars Saved = (Existing kWh – Proposed kWh)*Dollars/kWh = $ 137.6

Implementation Costs: The software program to manage PC power is a free program available from Verdiem. The cost for installing the program on each computer and making the necessary settings is based on an average of twenty minutes per computer or $ 10.00 labor cost.

Operations and Maintenance: The additional time the computers spend in standby mode should slightly increase their life since hard disks are not spinning in standby mode and power supplies are at minimum output.

EES2. Energy Management System:

Existing Conditions: Controls throughout the building are electronic programmable thermostats wired to rooftop air handling units. The programmable thermostats are set for occupied/unoccupied periods based on a seven day clock. The system does not allow for holiday scheduling and thermostat setpoints can be overridden by anyone in the building. Once overridden the system will remain in that mode indefinitely. Proposed Upgrades: Remove existing electric/electronic controls and provide new direct digital control (DDC) system. Provide DDC controls for rooftop air handlers. A new DDC control system will allow the use of additional energy saving control strategies and will provide additional operational benefits. Provide a graphical user interface with user friendly graphics that will allow simple adjustments of schedules and temperature setpoints by authorized building occupants. Interface the new controls to the school district’s central operator workstation through the district wide computer LAN. Provide graphical user interface software, and provide sufficient training as required to allow the customer to perform setpoint and schedule adjustments. Some examples of energy saving strategies that are available with DDC controls are:

1. Enhanced time of day scheduling and automatic holiday scheduling. 2. Data trending. Status of points can be electronically monitored to aid in troubleshooting. 3. Tighter space temperature control. 4. Graphical user interface allows the on-staff facilities personnel to monitor and make

adjustments to the control system parameters. 5. All DDC space sensors can be individually monitored to help with identifying

temperature control problems. 6. Night setback savings are maximized because each room can be set back during

unoccupied times. 7. Control rooftop units through the direct digital control system. 8. Mount all new space sensors at ADA approved height.

The energy management system payback exceeds the typical payback period for other recommended energy conservation measures. The benefits of an energy management system go beyond the hard savings from reduced utility bills and the system can provide the basis for ongoing energy management strategies and operations.

NOTES:

Savings Calculations: Changes to the building operation from installing an energy management system were modeled in the eQuest simulation software. Energy savings are calculated as follows: Electrical Annual Savings = (kWh Base – kWh EMS)* Dollars/kWh = 2,280*$0.071 = $161.88 Propane Annual Savings=MMBTU Base – MMBTU EMS * Dollars/MMBTU=31.89* 17.18=$547.87 Total Annual EMS Savings = Electrical Savings + Propane Savings = $709.75 See the eQuest report title TStat Management EEM on the following page:


02/04/11 Page 33


02/04/11 Page 34

Implementation Costs: The cost to furnish and install the energy management system was calculated using the actual cost of the direct digital control system components and standard labor factors. These costs were figured by a major energy management manufacturer/contractor. Operations and Maintenance: This measure involves the installation of new controls. New controls will need to be maintained and software will need to be periodically updated following the manufacturer’s recommendations. The new control system will simplify the maintenance of occupancy schedules and setpoints. The current system requires physically going to each thermostat and reprogramming the thermostat to account for holiday and summer shutdown periods. With the new system thermostat management can all be done from the front end computer.

EES4. Building Insulation: Existing Conditions: A building envelope survey has been performed to evaluate the need for building envelope insulation. The amount of insulation in the roof was R19 and is considered typical for a building of this age. Proposed Upgrades: The building should have R30 which is recommended for this area. Install insulation in the roof to make it to R30.

EES8. Variable Frequency Drives on Rooftop Units: Existing Conditions: The existing rooftop units have constant volume fans that supply air to the spaces. These fans are balanced by adjusting sheaves on the fan shaft

Proposed Upgrades: Variable frequency drives (VFD’S) could be installed on the fans for the rooftop units. These fans will allow softstart of the fans and the fans could be balanced by changing the frequency of the variable drives. If the energy management system were implemented the variable frequency drives could be controlled by that system to save even greater amounts of energy. Savings Calculations: These calculations are for fixed speed adjustment only and are for one unit Annual Energy Savings Estimator for VFD's on HVAC ApplicattionsCompares VFD capacity control versus other types capacity control.

To make Comparisons and Estimate Savings, need to know following:a. Motor horsepower.b. Cost of KwH of electricity.c. Total hours of operation per year.d. Present method of capacity control (guide vanes, fan curves, discharge vanes, control valves, etc.)

that VFD will replace.

Step 1 : Converting motor Horsepower to Kw2 HP x .746 = 1.492 KwA

Step 2 : Multiply the Adjustable Frequency Drive Power Ratio (from table below) times KwA from Step 1.0.73 Ratio x 1.492 KwA = 1.08916 KwB (using VFD)0.28

Step 3 : Multiply the Power Ratio of the presently employed control (see below) times KwA from Step 1. 0.88 Ratio x 1.492 KwA = 1.31296 KwC (method now employed)

Step 4 : Subtract Step 2 KwB from Step 3 KwC.1.31296 KwC

_ 1.08916 KwB = 0.2238 KwD (savings using VFD)

Step 5 : Multiply Step 4 KWD savings, times hours per year of operation, times cost of electricity per KwH.0.2238 KwD x 2000 Hrs = 448 KwH VFD Annual Calculated Savings

Implementation Costs: The estimated implementation costs for Variable Frequency Drive installation were provided by an equipment supplier. Operations and Maintenance: This measure should reduce maintenance cost on the air handling units due to soft starts causing less wear and tear on the belts and motors.

EES9. Submetering: Existing Conditions: The sharing of propane tanks among buildings makes accurate tracking of energy usage more difficult. Submeters at the building level would help track this data, but there are no energy savings from the meters themselves. Proposed Upgrades:

Install a submeter for propane usage at the elementary school. Savings Calculations: No energy savings are calculated for this measure. Implementation Costs: The estimated implementation costs for submetering were provided by a meter equipment manufacturer. Operations and Maintenance: This measure would increase operations cost because the meter would have to read manually.


02/04/11 Page 41

G. CONCLUSIONS AND RECOMMENDATIONS The Elida Elementary School’s energy usage is low compared with other schools throughout the United States. The four day school week, relatively mild weather, and existing operating practices all help lower energy costs. There is significant energy saving potential in upgrading the lighting system. Not only will this save energy, but it will improve the quality of the light. Occupancy sensors will keep lights off when areas are unoccupied, saving energy and prolonging the life of the system. The domestic hot water tank insulation, and computer power management solutions could be installed by District staff to reduce the overall cost of those measures. Energy conservation measures considered but not recommended may still present viable projects if the work is part of a planned renovation or if the specific pieces of equipment need extensive repairs or replacement. All paybacks were calculated assuming no increases in energy prices. Actual savings should exceed the simple payback savings over the life of the installed equipment and will help the District reduce the impact from anticipated rate escalations from energy providers.

It is recommended that the District pursue all sources of potential funding for the recommended energy conservation measures and implement as many of them as possible.

• MEASURES CONSIDERED BUT NOT RECOMMENDED

• CONCLUSIONS AND RECOMMENDATIONS

A. GENERAL BUILDING AND HVAC DESCRIPTIONS Building: The building structural system uses CMU with steel structure and brick veneer. The metal roof over the gym is original. The single-ply flexible membrane roof over the 1978 and 1983 construction was last replaced in 1994. The exterior doors are original to each building and are mostly hollow metal. Elida High School includes the high school, junior high classroom/office wing, cafeteria, kitchen, multi purpose room, library, old gym, and restroom/corridor addition. The Middle/High School contains 52,220 SF of permanent building area and uses CMU with steel structure and brick veneer. Originally constructed in 1926, there have been 5 additions to the school in 1967, 1978, 1983, 2002 and 2003 with the most recent addition of 8,825 SF Multi Purpose Faciltiy. The original 1926 Middle/High School was demolished and rebuilt in 2002. In 2003, a new metal building was constructed for VoAg programs. The exterior doors are original to each building and are mostly hollow metal. Exterior windows are original, operable doublepane, aluminum frame units. Heating/Cooling/Ventilation System: Heating and cooling for the building is supplied by combination rooftop air conditioning and gas heating units, and is distributed by ductwork. Fresh air is supplied through outside air intakes on rooftop package units. The classrooms, high school lockers, library, administration offices, computer labs and corridors are heated and cooled by Carrier packaged rooftop air handling units with indirect fired gas furnaces


02/04/11 Page 43

and direct expansion cooling. The gym is served by packaged make-up air conditioning units with evaporative cooler and gas fired forced air furnaces. These units have 100% outside air and 100% return air with dampers. Most of the units are controlled by programmable thermostats that cycle the units on a call for either heating or cooling. During unoccupied periods the units cycle to maintain unoccupied setpoints. The new Multi Purpose room was constructed in 2005 and is served by two Reznor unit heaters of 400 MBH capacity, two refrigerated air units and two exhaust fans. The Vo Ag building is served by one air conditioning unit, one evaporative cooler, two unit heaters and two exhaust fans. Lighting System: The lighting fixtures in the classrooms, lockers, hallways, and offices are a mixture of two or four lamp 32 watt T8 fluorescent with magnetic ballasts and incandescent lights in restrooms and for exit signs. The lighting fixtures in the multi purpose room are 400 watt metal halide and incandescent lights for exit signs. There are no automatic lighting controls. The lighting fixtures in the old gym are four lamp 32 watt T8 fluorescent and incandescent lights for exit signs. There are no automatic lighting controls. Building Envelope: The exterior walls of the high school/new gym/library addition and old gym buildings are solid masonry construction. The wall finishes consist of drywall and large windows which are a combination of doubled-glazed glass, aluminum metal frame. The steel roof deck is supported by open web steel joist. There are fiberglass insulation batts installed in each building with an approximately R-value of R-19. Exterior doors are steel with deteriorated weather stripping and caulking.

B. ANNUAL ENERGY USE Below is annual energy usage per utility broken out by end use.


02/04/11 Page 45

Energy Usage Base Year Data: Energy bills were provided by Elida Municipal Schools for two full years, starting with Jan 2008 and going through Nov 2009. These bills were normalized and a base year of Jan 2008 – Dec 2008 was selected. This is the most recent period for which utility data was available when the technical energy audit began. In general, base year data does not differ appreciably from data for the preceding year. The base year provides a basis for performing energy end use analyses a) to understand how energy is used in a given building and b) to identify savings opportunities during the early stages of the energy audit. Projected energy unit savings are compared to base year energy consumption to ensure that the projected savings are reasonable. “Whole building” energy models were developed for the sites included in the Technical Energy Audit using eQUEST version 3.63, build 6510. The eQUEST program uses “typical meteorological year” (TMY2) weather files rather than weather data files for a particular year. Therefore, utility data for buildings modeled using eQUEST were averaged for a two to three year period (depending on availability of utility data) in order to calibrate the eQUEST models for those buildings properly. Potable water for Elida Municipal Schools is provided by the Town of Elida. The school district is billed a flat rate per water meter so any savings in water would not result in lower bills. For this reason potable water conservation measures were not evaluated. The annual energy use index (EUI) for Elida High/Vocational/Agricultural School is:

40,530 BTU/Square Foot. The annual energy cost per square foot for Elida High/Vocational/Agricultural School is:

$ 0.96/Square Foot.

C. ENERGY BENCHMARKING Energy Benchmarking: Each building was entered in the Environmental Protection Agency’s Portfolio Manager Software to generate a benchmark for the building compared to other elementary schools throughout the United States. The facility report shows a very low energy intensity rating for this building and gives it an Energy Performance Rating of 96, i.e. this building’s energy usage is lower than 96% of the existing schools in the survey database.


02/04/11 Page 48

D. ENERGY CONSUMPTION BY END-USE Energy Consumption by End-use: The building was modeled in eQuest Version 3.63 Building Simulation Software to allocate energy usage in the building and to provide a baseline for energy savings calculations for certain energy conservation measures. The eQuest model predicted electrical energy usage 4.0% above measured use and propane energy at 4.0% below measured use.

Initial Savings and Investment Summary for Recommended Project:Elida High/Middle School

Commercial rebates are not currently offered by either Roosevelt County Electric Cooperative or Conway Oil Company. Energy Conservation Measure Interactions Measure interaction effects have not been calculated since the intent of this study is to identify and prioritize energy savings opportunities. If multiple energy conservation measures are implemented total energy savings could be slightly reduced due to interactive effects depending on which combination of measures are implemented. Implementing lighting retrofits will reduce the heat generated by the lighting system. During the heating season the reduced heat produced by the lights will need to be replaced by the building heating system. During the cooling season the reduced heat produced by the lights will result in reduced energy needed to cool the space. The added heating costs will be roughly negated by the reduced cooling costs. Building weatherization/insulation/windows energy conservation measures will reduce both heating and cooling costs. These measures will reduce the savings attributed to the heating/cooling of the building since it will reduce the base load for the building. The energy conservation measures affected by weatherization/insulation/windows include the energy management system, economizer retrofits, as well as the heating/cooling equipment replacements. Variable frequency drives on supply fan motors will reduce the fan speed depending on the building load thereby reducing the heat generated by the fan. This results in reduced cooling costs during


02/04/11 Page 50

cooling season and increased heating costs during heating season. These load changes are negligible because of the size of the fan motors. Computer power management and indoor vending machine setback will have an effect on the building heating/cooling loads similar to the lighting retrofits, only on a much smaller scale. Insulating domestic hot water tanks will not influence the other loads in the building because most of the water heaters are located in areas that are not actively heated or cooled. Freezer/cooler savings measures will not influence the other loads in the building because most of the equipment is ventilated in areas that are not actively conditioned spaces.

EHS1. Energy Policy:

Existing Conditions: The Elida Municipal School district works to manage its energy use. Most thermostats were set up correctly and teachers seem conscientious about turning off lights when leaving the classroom. The school currently has an energy policy that is not highly publicized or well known by members of the school community.

Proposed Upgrades: An active, dynamic Energy Policy is fundamental in order for the District to (a.) reduce the impact utility costs have on the budget, (b.) ensure that energy is used efficiently, and to (c.) maintain a reliable supply of energy to meet the functional needs of the District.

The school district should re-examine their current energy policy and review it to make sure it embraces all aspects of energy conservation. The update of this policy is the joint responsibility of board members, administrators, teachers, students and support personnel and its success is based on cooperation at all levels.

The energy policy should also be highly conspicuous and known to all stakeholders. Copies of the policy and energy conserving posters should be posted in public areas. The policy should be available on the district’s web site. A sample Energy Policy is included in the appendix. The Elida Municipal School District may wish to use this sample as a guide to modify/updating their existing policy. Savings Calculations: No additional savings were calculated for implementing an Energy Policy. Implementation Costs: An Energy Policy is developed and maintained by all stakeholders. The primary cost of implementation is the labor involved to review the policy and to make modifications to it. This work should be accomplished during the normal course of doing business and should not be an additional expense.

Operations and Maintenance: This measure is primarily an operations and maintenance activity. It is the summation of many small activities done by everyone involved in the school district.

EHS3. Lighting Upgrades:

Existing Conditions: A lighting survey has been performed to evaluate the need for lighting efficiency upgrades.

Proposed Upgrades: The following table details the existing and proposed lighting system in this building. The Burn Hour Code references the table following this table and indicates the run hours for each lighting area. The Lighting Code indicates the type of new lighting. If the Lighting Code starts with an N then this indicates a new fixture and includes new ballasts. If the Lighting Code starts with an R then this indicates a retrofit fixture and includes new ballasts for fixtures using ballasts. The type of ballast is indicated by the last set of digits of the Lighting Code – LP for Low Power, SP for Standard Power, and HP for High Power

The following formulae were used to calculate the energy saving from the lighting upgrades:

1) Kilowatts (kW) Existing kW = pre-retrofit unit kW Proposed kW = post-retrofit unit kW Total Existing kW = Existing kW * Existing Qty * Global Diversity Total Proposed kW = Proposed kW * Proposed Qty * Global Diversity Total Saved kW = Total Existing kW – Total Proposed kW Total kW Dollars Saved = Total Saved kW * kW rate 2) Kilowatt-hours (kWh) Total Existing kWh = Total Existing kW * Hours of Operation Total Proposed kWh = Total Proposed kW * Hours of Operation Total Saved kWh = Total Existing kWh – Total Proposed kWh Total kWh Dollars Saved = Total Saved kWh * kWh rate 3) Total Dollars Saved Total Dollars Saved = Total kW Dollars Saved + Total kWh Dollars Saved + O&M Saved Global Diversity and Diversity Factor (DF) are the probability that a particular lighting fixture will be on at the time of the facility’s peak load. Savings Calculations Summary: The existing and proposed lighting system run hours from the hour tables above were reduced to 79% of the table values to match the lighting load with the utility bills: Upgraded Quantity of Luminaires 603Total kW Used (Existing System) with DF 48.99Total kW used (Existing System) without DF 60.48Total kW Used (Upgraded System) with DF 26.70Total kW used (Upgraded System) without DF 35.32Total kW Saved 22.29Total kW Saved - Max Potential 25.16Total kWh Used (Existing System) 129,253Total kWh Used (Upgraded System) 54,913Total kWh Saved 74,339Occupancy Sensor Savings Total kWh (Included in Totals 23,499Occupancy Sensor Savings (Included in Totals) $1,645Total Savings (Energy) $7,277HVAC Penalty or Savings $0Total Maint.

The life expectancy of the lighting upgrades depends on the type of fixture/bulb installed and annual hours of usage of the lights. Below is a chart with typical life expectancy for different lighting components:

Implementation Costs: The cost to remove the existing lighting system and install the new lighting system was figured using actual cost for the new bulbs, ballasts and fixtures and standard labor factors for their installation. Costs were figured by a lighting contractor who specializes in lighting upgrades. Operations and Maintenance: Operations and maintenance savings for the lighting retrofit are based on the difference between the existing lamp and ballast replacement rate and lamp and ballast replacement rate for the proposed upgrade. The first step is to calculate the Existing Average Annual Lamp Burn Outs (EAALB). This is the percentage of annual percentage of burned out lamps expected each year. It is calculated by dividing the annual hours of operation by the manufacturers stated lamp life, then multiplying by the number of lamps/ballast in each fixture.

Next, the Existing Average Annual Lamp Burn Outs percentage is multiplied by the Existing Estimated Lamp Purchase Cost (EELPC), giving us the Existing Estimated Lamp Replacement Cost (EELRC). This cost is assumed based on historical data.

The total annual cost of replacement lamps per fixture which is then multiplied by the Total Number of Existing Fixtures (TNEF) resulting in the Existing Total Lamp Replacement Material Cost (ETLRMC).


02/04/11 Page 59

The above equations are then repeated for the proposed lighting system. The difference between the Existing Total Lamp Replacement Material Cost and the Proposed Total Lamp Replacement Material Cost will yield the Total Lamp Material Savings (TLMS).

Similar calculations are repeated for ballasts. Labor costs are calculated for replacing the number of units defined by the above equations. It is assumed lamps will be changed by custodial staff and ballasts will be replaced by an electrician. The total lamp labor savings and total ballast labor savings are then added together to yield the Total Labor Savings (TLS).

Finally, the Total Labor Savings is added to the Total Material Savings to yield the Total Maintenance Savings.

Total Labor Savings = Total Labor Savings + Total Material Savings See Appendix for full set of equations.

Proposed Upgrades: Caulk all windows indoors and outdoors and replace weather stripping on all exterior doors. Replace door seals on overhead doors. The caulking, weather stripping and door seals will reduce air leakage through the building envelope. Controlling air leakage is one of the most important functions of weatherization, and often the most difficult. The main goals of air leakage control are to: save energy, increase comfort, protect insulation’s thermal integrity, reduce direct cooling or heating of people and building components by outdoor air, and avoid moisture migration into building cavities.

The presence of insulation in the flat roof was spot-checked and was noted to be R19 with the exception of classrooms #304 & 303 was found be void of insulation. We recommend to install fiber glass batt insulation (R30) in classroom #304 & #303 (approximately 1881 sf).

The average useful life for caulking varies by type of caulking used. High-quality caulking compounds with a long life expectancy are generally more expensive, but end up being the most cost effective. Assuming that the caulking material is used outside as directed by the manufacturer, the following useful life may be expected: Silicone-30 years; polysulfides, polyurethanes, neoprene, acrylic, vulcanized butyl rubber-20 years; acrylic-latex, butyl rubber, and synthetic caulking compounds-8 to 10 years; cheaper caulking compounds-3 to 5 years. This energy conservation measure assumes the use of caulking with a 20 -30 year life expectancy.

Weather stripping comes in a variety shapes and sizes. Interlocking metal weather stripping is made of two V-strips that are placed on the door and the door frame. When the door closes, the two pieces interlock to make a tight seal. Interlocking pieces are placed completely around the perimeter of the door — on the top, both sides and the bottom. Tubular rubber and vinyl gaskets consist of small tubes of sponge rubber or vinyl also can be used to weather strip around doors and windows. When the door presses against the gasket, it forms a tight seal. By pressing against these gaskets, the door forms a seal. The type of weather stripping used depends on the condition and type of the existing door and frame. These two types of weather stripping have a life expectancy between five and eight years.

EHS6. Computer Power Management: Existing Conditions: The existing computers in the classrooms and offices are turned on and off by the teachers or administrative staff. Some individuals turn their computers off daily and some leave them running. Computers in the High School computer labs are turned on Monday mornings and turned off Thursday afternoons.

Proposed Upgrades: Install power management software that allows for scheduling standby modes. This software needs to be loaded on each computer and provides enhanced power management. Savings Calculations: The following formulae were used to calculate the energy saving from the computer power management:

1) Kilowatt-hours (kWh) Existing Existing Active Mode = 200 watts per PC/monitor combination Existing Standby Mode = 22 watts per PC/monitor combination Average Hours per Week of Active Mode = 40 Average Hours per Week of Standby Mode = 40 Weeks per Year = 40 Total Existing Active kWh per PC/Monitor = Existing W * Hours/Week * Weeks/1000 = 320 Total Existing Standby kWh per PC/Monitor = Existing W * Hours/Week * Weeks/1000 = 35 Total Existing kWh per PC = Active kWh + Standby kWh = 355 Total Existing kWh = # of PC/Monitors (62)* Total kWh/PC = 22,010 2) Kilowatt-hours (kWh) Proposed Proposed Active Mode = 200 watts per PC/monitor combination Proposed Standby Mode = 22 watts per PC/monitor combination Average Hours per Week of Active Mode = 36 Average Hours per Week of Standby Mode = 44 Weeks per Year = 40 Total Proposed Active kWh per PC/Monitor = Proposed W * Hours/Week * Weeks/1000 =288 Total Proposed Standby kWh per PC/Monitor = Proposed W * Hours/Week * Weeks/1000 = 39 Total Proposed kWh per PC = Active kWh + Standby kWh = 327 Total Proposed kWh = # of PC/Monitors (62)* Total kWh/PC = 20,274 3) Total Dollars Saved Total Dollars Saved = (Existing kWh – Proposed kWh)*Dollars/kWh = $ 121.52

Implementation Costs: The software program to manage PC power is a free program available from Verdiem. The cost for installing the program on each computer and making the necessary settings is based on an average of twenty minutes per computer or $ 10.00 labor cost.

Operations and Maintenance: The additional time the computers spend in standby mode should slightly increase their life since hard disks are not spinning in standby mode and power supplies are at minimum output.

EHS7. Insulate Domestic Hot Water Tank: Existing Conditions: Gas fired domestic hot water heaters located in the storage, lounge, mechanical room and kitchen closet provide domestic hot water to the High School, gyms and kitchen. The majority of the hot water is used in the locker rooms for showers and kitchen. The existing water heater jacket has an approximate R-value of 7.

Proposed Upgrades: Install a water heater insulating blanket around the domestic hot water tank. The total R-value for the tank will now be 12. Savings Calculations: Water heater base case and modifications were run in the eQuest simulation software with the following results:

EHS8. Freezer/Refrigerator Modifications: Existing Conditions: Two walk-in cooler and one walk-in freezer provide food storage for the cafeteria operations. Each cooler has one or more evaporator units, each with two small fans that continuously move air across the evaporator coils to circulate the cooled space. These evaporators are equipped with relatively low efficiency shaded-pole induction type electric fan motors. Proposed Upgrades: Replace the existing shaded-pole motors with Electronically Commutated Motors (ECM). An ECM combines the inherent efficiency of a DC motor design with an electronic drive control in a package small enough to easily fit inside a typical evaporator unit. The ECM will dramatically reduce the energy consumption of the evaporators.

An additional benefit is a reduction of heat imparted to the cooler. Since all of the electrical energy that the evaporator fan consumes is ultimately converted into heat, a reduction in fan energy will translate into an equal reduction in internal heat load. This ultimately results in less energy required by the system’s condensing unit to maintain the same temperature within the space. These additional saving, though real, were not accounted for in the savings analysis.

EHS9. Vending Machine Setbacks: Existing Conditions: One beverage vending machine and two reach-in coolers are located in the high school. The coolers were maintaining temperatures of about 35 degrees F.

Proposed Upgrades: Install vending miser controllers on the beverage vending machine and the two reach-in coolers. The vending misers use an occupancy sensor that will automatically shut down the controlled vending machine when the area around the machine has been vacant for fifteen minutes. The controller will periodically re-power the machine to ensure the vended products stay cold. The controller senses the vending machine’s compressor status and will delay power-down of the vending machine until the compressor has completed its cooling cycle. Do not install vending miser on vending machine/coolers that store perishable products. Savings Calculations and Implementation Costs:

EHS2. Energy Management System:

Existing Conditions: Controls throughout the building are electronic programmable thermostats wired to rooftop air handling units. The programmable thermostats are set for occupied/unoccupied periods based on a seven day clock. The system does not allow for holiday scheduling and thermostat setpoints can be overridden by anyone in the building. Once overridden the system will remain in that mode indefinitely. Programmable thermostats are located at seven feet above floor level which is not a recommended location. Proposed Upgrades: Remove existing electric/electronic controls and provide new direct digital control (DDC) system. Provide DDC controls for rooftop air handlers and gas unit heaters. A new DDC control system will allow the use of additional energy saving control strategies and will provide additional operational benefits. Provide a graphical user interface with user friendly graphics that will allow simple adjustments of schedules and temperature setpoints by authorized building occupants. Interface the new controls to the school district’s central operator workstation through the district wide computer LAN. Provide graphical user interface software, and provide sufficient training as required to allow the customer to perform setpoint and schedule adjustments. Some examples of energy saving strategies that are available with DDC controls are:

1. Enhanced time of day scheduling and automatic holiday scheduling. 2. Data trending. Status of points can be electronically monitored to aid in troubleshooting. 3. Tighter space temperature control. 4. Graphical user interface allows the on-staff facilities personnel to monitor and make

adjustments to the control system parameters. 5. All DDC space sensors can be individually monitored to help with identifying

temperature control problems. 6. Night setback savings are maximized because each room can be set back during

unoccupied times. 7. Mount all new space sensors at ADA approved height.

The energy management system payback exceeds the typical payback period for other recommended energy conservation measures. The benefits of an energy management system go beyond the hard savings from reduced utility bills and the system can provide the basis for ongoing energy management strategies and operations.

Savings Calculations: Changes to the building operation from installing an energy management system were modeled in the eQuest simulation software with the following results:


02/04/11 Page 73

Energy savings are calculated as follows: Electrical Annual Savings = (kWh Base – kWh EMS)* Dollars/kWh = 5380*$0.07 = $377 Propane Annual Savings=MMBTU Base – MMBTU EMS * Dollars/MMBTU=133.4* $17.2 = $2294.5 Total Annual EMS Savings = Electrical Savings + Propane Savings = $2671.5 Implementation Costs: The cost to furnish and install the energy management system was calculated using the actual cost of the direct digital control system components and standard labor factors. These costs were figured by a major energy management manufacturer/contractor. Operations and Maintenance: This measure involves the installation of new controls. New controls will need to be maintained and software will need to be periodically updated following the manufacturer’s recommendations. The new control system will simplify the maintenance of occupancy schedules and setpoints. The current system requires physically going to each thermostat and reprogramming the thermostat to account for holiday and summer shutdown periods. With the new system thermostat management can all be done from the front end computer.

EHS10. Variable Frequency Drives on Rooftop Units: Existing Conditions: The existing rooftop units have constant volume fans that supply air to the spaces. These fans are balanced by adjusting sheaves on the fan shaft

Proposed Upgrades: Variable frequency drives (VFD’S) could be installed on the fans for the rooftop units. These fans will allow softstart of the fans and the fans could be balanced by changing the frequency of the variable drives. If the energy management system were implemented the variable frequency drives could be controlled by that system to save even greater amounts of energy. Savings Calculations: These calculations are for fixed speed adjustment only and are for one unit Annual Energy Savings Estimator for VFD's on HVAC ApplicattionsCompares VFD capacity control versus other types capacity control.

that VFD will replace.

Step 1 : Converting motor Horsepower to Kw2 HP x .746 = 1.492 KwA

Step 2 : Multiply the Adjustable Frequency Drive Power Ratio (from table below) times KwA from Step 1.0.73 Ratio x 1.492 KwA = 1.08916 KwB (using VFD)0.28

Step 3 : Multiply the Power Ratio of the presently employed control (see below) times KwA from Step 1. 0.88 Ratio x 1.492 KwA = 1.31296 KwC (method now employed)

EHS11. Submetering: Existing Conditions: The sharing of propane tanks among buildings makes accurate tracking of energy usage more difficult. Sub meters at the building level would help track this data, but there are no energy savings from the meters themselves. Proposed Upgrades:

Install sub meters for propane usage at the separate buildings. Savings Calculations: No energy savings are calculated for this measure. Implementation Costs: The estimated implementation costs for sub metering were provided by a meter equipment manufacturer. Operations and Maintenance: This measure would increase operations cost because the meter would have to read manually.

EHS12. Window Replacement: Existing Conditions: The west facing windows of the computer lab and library are single-glazed units and several exit doors also have single-glaze glass panels. Replacement windows may be the best long-term solution for the Mid/High School. These 4 windows should be considered for replacement. Proposed Upgrades:

Window replacement is the best solution for the high school. Modern windows have superior weather-stripping, better insulating value against heat, cold, UV radiation and noise.

G. CONCLUSIONS AND RECOMMENDATIONS The Elida High School’s energy usage is low compared with other schools throughout the United States. The four day school week, relatively mild weather, and existing operating practices all help lower energy costs. There is significant energy saving potential in upgrading the lighting system. Not only will this save energy, but it will improve the quality of the light. Occupancy sensors will keep lights off when areas are unoccupied, saving energy and prolonging the life of the system. The domestic hot water tank insulation and computer power management solutions could be installed by District staff to reduce the overall cost of those measures. Energy conservation measures considered but not recommended may still present viable projects if the work is part of a planned renovation or if the specific pieces of equipment need extensive repairs or replacement. All paybacks were calculated assuming no increases in energy prices. Actual savings should exceed the simple payback savings over the life of the installed equipment and will help the District reduce the impact from anticipated rate escalations from energy providers.

It is recommended that the District pursue all sources of potential funding for the recommended energy conservation measures and implement as many of them as possible.

SAMPLE ENERGY POLICY

Energy Policy is fundamental in order for the District to (a.) reduce the impact utility costs have on the budget, (b.) ensure that energy is used efficiently, and to (c.) maintain a reliable supply of energy to meet the functional needs of the District.

It is the policy of the School District to conserve energy and natural resources. The implementation of this policy is the joint responsibility of board members, administrators, teachers, students and support personnel and its success is based on cooperation at all levels.

The Energy Policy is designed as part of the District's plan to save energy without infringement of the educational mission of the School District. School Principals, Maintenance Personnel and Administration will share the accountability for ensuring that this policy is followed. All operations of District facilities will be governed by established energy management guidelines, and participation is mandatory for all School District Personnel. The Superintendent will provide leadership and support for energy management and conservation, including use of energy audits and conservation programs. Judicious use of the various energy conservation efforts will be the joint responsibility of the Superintendent and School Principals. The Superintendent /designee will report District energy conservation efforts to the Board of Education.

ELIDA MUNICIPAL SCHOOLS LIGHTING MAINTENANCE FORMULAE


02/04/11 Page A-9

Overview The following describes both the material and labor savings calculations associated with a lighting retro-fit. Please see the Room-by-Room worksheet for actual values specific to the project. Material Maintenance Calculations: Lamps The first step is to calculate the Existing Average Annual Lamp Burn Outs (EAALB). This is the percentage of annual percentage of burned out lamps expected each year. It is calculated by dividing the annual hours of operation by the manufacturers stated lamp life, then multiplying by the number of lamps in each fixture. See Eq.1. Eq.1

Next, the Existing Average Annual Lamp Burn Outs percentage is multiplied by the Existing Estimated Lamp Purchase Cost (EELPC), giving us the Existing Estimated Lamp Replacement Cost (EELRC). This cost is assumed based on historical data. If actual costs are known, they can be substituted into the calculations. See Eq.2. Eq.2

Equation 2 gives the total annual cost of replacement lamps per fixture which is then multiplied by the Total Number of Existing Fixtures (TNEF) resulting in the Existing Total Lamp Replacement Material Cost (ETLRMC). See Eq.3. Eq.3

Equations 1-3 are then repeated for the proposed lighting system. The difference between the Existing Total Lamp Replacement Material Cost and the Proposed Total Lamp Replacement Material Cost will yield the Total Lamp Material Savings (TLMS). See Eq.4. Eq.4

Material Maintenance Calculations: Ballasts The first step is to calculate the Existing Average Annual Ballast Burn Outs (EAABB). This is the percentage of annual percentage of burned out ballasts expected each year. It is calculated by dividing the annual hours of operation by the manufacturer’s stated operating life, then multiplying by the number of ballasts in each fixture. See Eq.5. Eq.5

Next, the Existing Average Annual Ballast Burn Outs percentage is multiplied by the Existing Estimated Ballast Purchase Cost (EEBPC). This cost is assumed based on historical data. If actual costs are known, they can be substituted into the calculations. See Eq.6. Eq.6


02/04/11 Page A-10

Equation 2 gives the total annual cost of replacement ballasts per fixture which is multiplied by the Total Number of Existing Fixtures (TNEF) resulting in the Existing Total Ballast Replacement Material Cost (ETBRMC). See Eq.7. Eq.7

Equations 1-3 are then repeated for the proposed lighting system. The difference between the Existing Total Ballast Replacement Material Cost and the Proposed Total Ballast Replacement Material Cost will yield the Total Ballast Material Savings (TLMS). See Eq.8. Eq.8

The total lamp material savings and total ballast material savings are then added together to yield the Total Material Savings (TMS). See Eq.9 Eq.9

Labor Maintenance Calculations If material maintenance savings can be included in the project, two labor wages rates are necessary for calculations, a typical custodian and electrician. Both wage rates are specific to the location of the project. Labor Maintenance Calculations: Lamps The first step is to calculate the Existing Labor Cost for Lamps (ELCL). This is the annual cost to change burned out lamps per fixture. First multiply the percentage of annual lamp burnouts (see Eq.1) times the time required to change the lamps in a fixture times the hourly wage rate for a custodial employee. The custodial wage rate is used in lieu of an electrician’s hourly rate for lamps only. Eq.10 Eq.10

Next the Existing Labor Cost for Lamps (ELCL) is multiplied times the total number of existing fixtures yielding the Existing Total Lamp Labor Cost (ETLLC). See Eq.11 Eq.11

Equations 6 and 7 are then repeated for the proposed lighting system. The custodial hourly wage rate is held constant throughout the existing and proposed labor costs for lamps. The difference between the Existing Total Lamp Labor Cost (ETLLC) and the Proposed Total Lamp Labor Cost (PTLLC) will yield the Total Lamp Labor Savings (TLLS). See Eq.12 Eq.12

Labor Maintenance Calculations: Ballasts The first step is to calculate the Existing Labor Cost for Ballasts (ELCB). This is the annual cost to change burned out ballasts per fixture. First multiply the percentage of annual ballast burnouts (see Eq.5) times the time required to change the ballasts in a fixture times the hourly wage rate for a electrician. The electrician wage rate is used since re-wiring will be necessary. See Eq.13. Eq.13

Next the Existing Labor Cost for Ballasts (ELCB) is multiplied times the total number of existing fixtures yielding the Existing Total Ballast Labor Cost (ETBLC). See Eq.14 Eq.14

Equations 13 and 14 are then repeated for the proposed lighting system. The electrician hourly wage rate is held constant throughout the existing and proposed labor costs for ballasts. The difference between the Existing Total Ballast Labor Cost (ETBLC) and the Proposed Total Ballast Labor Cost (PTBLC) will yield the Total Ballast Labor Savings (TBLS). See Eq.15 Eq.15

The total lamp labor savings and total ballast labor savings are then added together to yield the Total Labor Savings (TLS). See Eq.16 Eq.16

Finally, the Total Labor Savings is added to the Total Material Savings to yield the Total Maintenance Savings. See Eq.17 Eq. 17
