Annual Site Inspection Results

Honeywell Building Solutions SES personnel Mr. Carlos Taylor visited Gary Job Corp (GJC) on March 25 thru March 26 of 2009, to perform an annual inspection of the installed ECMs and met with Mr. Howard Mosesman. Honeywell Building Solutions SES sited HVAC installations and modifications campus wide. The Honeywell retrofitted equipment was physically inspected and some data was measured/collected. The collected information was recorded into Tables 2 thru 5 and attached in Section 5.

Temperature Setback

A sample of 11 thermostats was checked for proper programming and accuracy of reading.

The sample showed that mostly, the units are not observing the setback program. The M&V plan called for a monthly inspection by the GJC maintenance staff of the thermostats to ensure that the proper programming is persistent. The monthly maintenance program is not in compliance, therefore negatively impacting the savings from this ECM. While the Carrier brand programmable thermostat may contain the appropriate schedule it is important to know that while in the “Auto” mode, the thermostat continuously maintains the current setpoint and automatically transitions between AC and Heat as conditions change. In order for the schedule to be recognized in the Carrier programmable thermostat it should be placed in the “Program On” mode. Appendix B includes “The Owner’s Maintenance and Operation Responsibilities”. The GJC maintenance personnel continue to replace failed thermostats with the Carrier Debonaire 450 programmable thermostat. Buildings with limitation in air conditioning capacity and/or added large number of computers that require certain conditions may be exempt from the setback and should be documented as such. After ensuring that all the proper schedules are active, the GJC maintenance personnel should document any request of changing the schedule and maintain the monthly inspection as required by the M&V plan (Appendix A). This will ensure the persistence of the estimated savings.

Replacement of Condensing Units personnel inspected all condensing units installed campus wide. Over the years the GJC maintenance staff has had to replace 8 of the 23 condensing units installed by Honeywell resulting in an overall increase in cooling capacity. Eight condensing units were not operational at the time of this inspection therefore no amp measurements were taken for these units. The GJC maintenance staff will submit the work orders for these units to be serviced as they are needed.

Replacement of Rooftop Units personnel inspected all seven Carrier rooftop units installed. Some units control circuits were jumpered to initiate a run sequence in order to take measurements.

Two of the seven RTUs did not run therefore no measurements were taken for these particular units. All other units were verified as operational and are in good working condition. The GJC maintenance staff seems to be on top of the maintenance issues concerning these units, which was evident by the technicians working on a unit during this inspection.

Re-Commissioning of the Solar Water Heating System Gary Job Corp clearly shows no interest in reviving this ECM and there are no immediate future plans to re-commission this system rendering no savings for this ECM. The photos below show a section of an array of solar panels that are located on the rooftop of the cafeteria and the circulating pump for the system located in the mechanical room below. All problems associated with the solar water heating system are carryovers from the 2004 calendar year. They are:

solar collectors are broken, sensor wiring is damaged and the systems electronic control module failed.

Activating Outside Air Vents

There are no estimated savings associated with the outside air vent operation for the five rooftop units at Building 7-100, shown above. A GJC contractor replaced four of the original units with new Bryant models which have no installed fresh air ventilation. Honeywell Building Solution SES personnel opened two of the units and found their respective fresh air kits stored inside. These fresh air kits have been stored inside these units since their installation. Honeywell Building Solution SES recommends installing all four fresh air kits so that the air quality will be improved in this building.

Lighting Upgrades

Honeywell Building Solutions SES personnel did not perform a lighting inspection this year. The next inspection should be performed in the 2009 calendar year. All lighting maintenance responsibilities are being carried out by Gary Job Corp per the M&V Plan.

Retrofitting High Flow Sanitary Fixtures

As for the water conservation measure that was implemented by Honeywell Building Solutions SES, the GJC maintenance personnel did not report any significant increase in toilet blockage incidents. No significant maintenance problems have been reported. As per the M&V Plan, there is no required annual inspection for this measure.

Section 2: Background

The Gary Job Corps Center, located in San Marcos, Texas, is a federally funded job-training program for young adults between the ages of 16 and 24. Training is free for income eligible men and women. Gary's goal is to teach young adults the academic, vocational and social skills needed to get and keep a job.

Gary is one of the largest centers in the nation, with 2,200 men and women in training. The campus is 800 acres in size, with 200 buildings and one million square feet of building space. In earlier years, from February 1943 to the summer of 1959, the facility was used by the U.S. Air Force and U.S. Army to train navigators, helicopter pilots and rotary mechanics. From 1965 to 1995, the property has continuously been operated by the Texas Educational Foundation, Inc. for the U.S. Department of Labor.

The Gary Center offers training in 26 trades. Advanced training is offered in computers, automotive diagnostics and heating and air conditioning. When students complete trade training, they intern at local businesses utilizing their new job skills.

Gary Job Corps (GJC) Center contracted with Honeywell Building Solutions SES through a performance contract. The contract covers both energy and water conservation, in addition, reduces the operation and maintenance (O&M) costs.

As per the Measurement and Verification (M&V) plan, all the savings are stipulated. The contract calls for an annual inspection of the installed ECMs.

The inspection scope is detailed in the M&V plan (Appendix A).

ECM Descriptions ECM #1: Temperature Setback

This ECM consists of replacing standard thermostats with programmable setback thermostats. This allows the operating setpoint of the mechanical equipment to be adjusted by the time of day, reducing runtimes during periods of a day when there is no occupancy. The ECM includes the installation of 154 setback thermostats and 16 return air thermostats in 49 buildings.

The estimated savings from the setback schedules are:

Annual Energy Savings kWh/yr. Therms/yr. $/yr.

2,441,216 24,690 $56,082

ECM #2: Replacement of Condensing Units This ECM involves replacing condensing units that are old and deteriorated with new, more efficient units. The renovation includes replacing the compressor, condenser, evaporator and refrigerant lines in 23 units located in 12 buildings

The estimated savings from these replacements are:

159,348 165 $10,478

ECM #3: Replacement of Rooftop Units This ECM involves replacing seven-rooftop package air conditioning units located on the roof of the Dinning Hall (Building 7-300) with new high efficiency units of like size. The new units run more efficiently and for shorter periods of time.

The estimated savings from these replacements are:

335,753 -1,065 $13,545

ECM #4: Re-Commissioning of the Solar Water Heating System The solar water heating system located on the roof of the Dinning Hall (Building 7-300) is non-operational. This ECM involves the repair and re-commissioning of the system, reducing the amount of natural gas that is necessary for heating the domestic hot water.

The estimated savings from this system are:

-6,807 17,832 $6,420

ECM #5: Activating Outside Air Vents This operation reactivates the outside air vents in the Orientation Building (Building 7-100) allowing fresh air to enter building. Although there is no energy savings associated with this measure, it will result in a more comfortable environment. There is a small penalty in utility costs in order to improve the air quality.

The estimated savings from this measure are

-19,600 -1,253 -$948

ECM #6: Lighting Upgrades This ECM involves retrofitting 6,151 lighting fixtures, resulting in an enhanced lighting quality and significant energy and demand savings. State –of-the-art technology was installed, providing the Center with virtually a new lighting system in those areas that are retrofitted.

The estimated savings from the lighting retrofit are:

1,172,907 -1,256.0 $60,420

ECM #7: Retrofitting High Flow Sanitary Fixtures Existing high flow toilets, urinals and showerheads were replaced with low flow models consistent with the requirements of the Energy Policy Act of 1992; i.e. 1.6 gallons per flush (GPF) for toilets, 1.0 GPF for urinals, and 2.5 gallons per minute (GPM) for showerheads. Additionally, high flow faucet aerators were replaced with efficient 0.5 GPM low aerators resulting in annual savings of over $63,000 from reduced water usage, reduced water heating costs and reduced pumping.

Section 3: M&V Plan

Site Specific Measurement & Verification Plan

Measurement and Verification Overview The proposed plan for monitoring and verifying savings from the installed ECMs is based on the methods described in the U.S. Department of Energy Federal Energy Management Program’s (FEMP) 1996 measurement and verification (M&V) protocol. This document was prepared for the DOE to assist government agencies entering into performance contracts and is based on the North American Energy Measurement and Verification Protocol (NEMVP), currently known as the International Performance Measurement and Verification Protocol (IPMVP).

The approach to M&V contained herein is consistent with the FEMP M&V Guidelines. However, since no specific M&V plan can be applied to every site, the plan has been customized to this particular project. The following table lists each ECM and shows which M&V option will be used, per the IPMVP / FEMP guidelines.

A – Stipulated, Electric increase A – Stipulated, Gas Savings

4 – HVAC 5 – Activate Outside Air Vents None

5 – Lighting 6 – Lighting

A – Stipulated, Electrical Savings A – Stipulated, Gas Increase

Concept Description

As indicated in Table 1, all ECM savings will be stipulated at the calculated annual amounts (see FEMP Guideline Option A). This approach has been chosen due to the relatively high cost and level of difficulty associated with the proposed ECSM’s. In this case, the cost of achieving an acceptable level of certainty in measurement simply out-weighs the benefit of achieving that certainty.

For each individual ECSM, the savings will be stipulated at an agreed-to annual amount. All supporting data, calculations and assumptions will be agreed-to by both parties. Payments in accordance with the stipulated energy savings will be made annually as long as Energy Pacific performs an annual site inspection of the ECSM’s. The annual site inspection will include visual verification that ECSM’s are installed and operating. Energy Pacific will submit a report of findings no more than 30 days following the site inspection.

Baseline Energy Consumption

ECM#1 – Thermostat Temperature Setback

The Trace 600 model used to calculate the baseline energy consumption (electricity and natural gas) of the cooling equipment will be defined as the baseline model. As modeled by Trace, the baseline thermostat schedules have been agreed-to as defined under Section 1 – ECM’s and Energy Savings:

ECM#1 – Temperature Setback: Assumptions and energy calculations.

ECM#2 – Condensing Unit Replacement

The Trace 600 model used to calculate the baseline power consumption for these units will be defined as the baseline model. As modeled by Trace, the baseline efficiency for these units has been agreed-to at 1.8 kW/Ton.

ECM#3 – Replacement of Cafeteria Roof-top Units

ECM#4 – Re-Commissioning of the Solar Water Heating System

The baseline for this ECM is defined simply as no solar impact on water heating.

The model used to quantify the savings calculates the impact of the solar collector in the form of energy transferred to the water. In the absence of a collector, the impact is zero.

ECM#5 – Open Outside Air Vents

This ECM is really not an ECM at all since the net impact is an increase in energy consumption. However, for the purpose of determining the impact, the Trace 600 model used to calculate the baseline power consumption will be defined as the baseline model. As modeled by Trace 600, the baseline outside air quantity has been agreed-to as zero, or no outside air.

ECM#6 – Lighting

The baseline for lighting consumption and demand is dependent on three factors. All of these will be stipulated. The baseline operating hours will be stipulated based on agreed-to run hours. The baseline fixture-ballast combination instantaneous power draw will be stipulated based on values available in a table of standard wattages. The E.P.A. Green Lights Manual will be used where applicable and manufacturer’s data sheets will be used where the E.P.A. manual does not apply. A pre-installation demand diversity factor will also be stipulated.

Post-Installation Energy Consumption and Baseline Adjustments

The post-installation energy consumption has been calculated using a model.

The details of this model have been made available to the owner. The cooling and heating energy savings will be stipulated at the amounts determined using the model. During the post-installation period, if it is determined that the setback schedule must be modified for reasons beyond the control of Energy Pacific then no adjustment will be made to the baseline or savings calculations.

If it is determined that such adjustments must be made to accommodate known conditions that existed during the pre-installation period then an appropriate adjustment equal to change in equivalent set-back ton-hours relative to the entire set of set-back ton-hours will be made to the savings calculations.

ECM#2 – Condensing Unit Replacement The Trace 600 model used to calculate the after-case power consumption for these units will be defined as the after-case model. As modeled by Trace, the new efficiency for these units has been agreed-to at 1.4 kW/Ton. Since the baseline and post-installation parameters used to calculate the energy savings are stipulated, no baseline adjustment is anticipated.

ECM#3 – Replacement of Cafeteria Roof-top Units The Trace 600 model used to calculate the after-case power consumption for these units will be defined as the after-case model. As modeled by Trace, the new efficiency for these units has been agreed-to at 1.4 kW/Ton. Since the baseline and post-installation parameters used to calculate the energy savings are stipulated, no baseline adjustment is anticipated.

ECM#4 – Re-Commissioning of the Solar Water Heating System The savings calculated due to reduced gas consumption as a result of the re-commissioning of the solar hot water heater have been submitted to the owner for review. The calculated savings will be stipulated for the term of the contract as long as the solar hot-water heater can be shown to be operating. No baseline adjustments will be made during the post-installation years.

ECM#5 – Open Outside Air Vents This ECM is really not an ECM at all since the net impact is an increase in energy consumption. However, for the purpose of determining the impact, the Trace 600 model used to calculate the after-case power consumption will be defined as the after-case model. As modeled by Trace 600, the after-case outside air quantity has been agreed-to as 2,754 cfm of fresh air going into the building at all times. No baseline adjustments will be made during the post-installation years.

ECM#6 – Lighting The post-installation energy consumption will be determined using calculations shown in Section 1 under ECM#6. Again, the post-installation operating hours, instantaneous demand, and demand diversity factor will be stipulated. In addition, a lighting control factor will be stipulated to account for changes in operating hours due to improved control. In addition, HVAC interactions will be stipulated at the calculated amounts. The HVAC interactions include cooling energy reduction and heating energy increase. Since the baseline and post-installation parameters used to calculate the energy savings are stipulated, no baseline adjustment is anticipated.

Methodology To Assign Dollar Value To Savings Calculating the units of energy saved is a critical measure of energy efficiency improvements, but it does not indicate the actual dollars saved. To do this, Energy Pacific and the client establish the base rate that will act as a "floor" rate in calculating the savings. These are usually the rates that are in effect at the time of the start of the contract between Energy Pacific and the client. For this project the baseline rate structure will be defined as the Lower Colorado River Authority Large General Service rate structure.

If at any time during the post-installation years, the effective rates are higher than the base rates, the dollar value of savings is calculated by computing the base year consumption at current rate dollars. This adjusted dollar base year is compared to the post-installation model at the current billing amount. The difference represents the dollar value of the energy saved.

If the effective rates are lower than the base rates, the dollar value of savings remains constant according to the stipulated monthly savings calculated at the conclusion of the Measurement Years. In short, the applied rate (base or current) will be that which results in the greatest dollar value of energy saved.

Energy Pacific does not anticipate setting a ceiling on utility energy rates, because the increase in savings benefits both parties. Energy Pacific does, however, set a floor on utility energy rates since Energy Pacific's contingent service fee would benefit the client and penalize Energy Pacific. The floor rate allows both parties to share the benefits as well as the drawbacks of the impacts due to rate changes.

The energy savings calculation is used to determine the amount of dollars saved from the energy savings portion of the project. The procedure is to take the adjusted energy savings and to multiply it by the appropriate fuel rate. This results in the dollars saved due to the energy reduction achieved by the project.

The following equation will be used to calculate the annual savings in dollars.

Performance/Savings Persistence Plan

Stipulated savings during the post-installation years will help to avoid significant annual costs for both parties by avoiding the cost of items such as savings calculations and reviews, resolving issues such as missing weather or consumption data, and baseline adjustments due to annual growth.

However, this method does not ensure savings persistence over the term of the contract. In order to ensure savings persistence, Energy Pacific will provide annual inspections of the ECM’s to verify that the ECM’s are installed and operating. The annual inspection will rely heavily on well-documented commissioning data. The commissioning data will be used by a field engineer from Energy Pacific in the presence of a representative of Gary Job Corps to verify the installation and operation of the ECM’s. Energy Pacific will provide an annual report to document the findings and make recommendations. The annual inspection, to begin in the second year of the contract will require no more than two man-days to complete and will consist of the following items.

ECM#1 – Thermostat Temperature Setback A random sample of 10% of the installed programmable thermostats will be checked for consistency with the commissioning data, including setback schedules and settings. Thermostats found to have settings that deviate from the original settings or operation will be reported to Gary Job Corps with recommendations for appropriate action on the part of Gary Job Corps.

ECM#2 – Condensing Unit Replacement A random sample of 10% of the replaced units will be visually inspected including condenser coil inspection and evaporator coil inspection. Signs of degradation will be reported to Gary Job Corps with recommendations for appropriate action on the part of Gary Job Corps.

ECM#3 – Replacement of Cafeteria Roof-top Units Each of the seven-rooftop units will be visually inspected including condenser coil inspection and chilled water coil inspection. Signs of degradation will be reported to Gary Job Corps with recommendations for appropriate action on the part of Gary Job Corps.

ECM#4 – Re-Commissioning of the Solar Water Heating System The field engineer will visually inspect the solar collector to be sure it is clean and in good working order.

ECM#5 – Open Outside Air Vents The field engineer will visually verify the operation of the outside air vent.

ECM#6 – Lighting The field engineer will perform a lighting inspection every third year beginning in the third performance year and ending in the final year of the contract. A random sample of 10% of the rooms receiving a lighting upgrade will be inspected. The field engineer will check the ballast and bulb(s) for one of the fixtures within each inspected room and take one illumination measurement in each inspected room. Deviations in equipment from the original installation will be reported to Gary Job Corps with recommendations for appropriate action on the part of Gary Job Corps.

Plan for Resolving Disputes

A well-defined M&V approach along with regular project meetings and reviews minimize the potential for a dispute. In the event of an actual dispute that cannot be resolved in a timely manner by mutual consent, it is recommended that an independent third-party review team be established to review and mediate issues. This third-party review team will be composed of individuals with the necessary technical knowledge and background to resolve the dispute. The members of this independent resolution team will be agreed upon by all parties involved, and will be provided all background material and data related to the disputed ECM(s). Based upon this information, a letter report will be prepared by the third-party reviewer, describing the disputed issue(s) and any actions necessary to resolve the dispute.

Section 4: Savings Analysis & Methodology

Table 1 shows the reported savings associated with the installed retrofits.

These savings were based on detailed Trace runs for the facility buildings for ECMs # 1 through 5 and spreadsheets for ECMs 6 and 7. The achieved savings have been negatively affected by the facility lack of maintaining programmable thermostats schedules and also replacing programmable thermostats with non-programmable ones. Also, lack of maintenance of the solar system has rendered the system inoperable for extended periods of time, which has negatively affected the savings from that measure.
