Addendum No. 1 Prepared March 25, 2011

to the Grady Municipal Schools Audit Prepared February 4, 2011 by Honeywell

PURPOSE OF ADDENDUM

1) Clarify heating fuel type; 2) Clarify interaction of energy conservation measures; 3) Clarify economizers.

HEATING FUEL TYPE Grady Municipal Schools uses propane for its heating fuel, as stated on page 6 of the energy audit report, and the baseline energy consumption used in analyzing energy conservation measures is based on the facility’s actual propane consumption. In Section B, “Annual Energy Use,” on page 10, the table and pie chart consumption data given is for propane, not “Natural Gas” as labeled. Propane consumption data used to establish the baseline is provided in the Appendix on pages A-7 through A-9. INTERACTION OF ENERGY CONSERVATION MEASURES A few of the interactions mentioned on page 16 in Section E, “Energy Conservation Measures,” will not be a factor in the proposed project. In the final analysis, energy management systems, economizers, heating/cooling equipment replacements, and variable frequency drives were not recommended to be implemented because they were not found to be cost-effective. These interactions do not apply. ECONOMIZERS Economizer operation recommendations in the Appendix on page A-3, items 7 and 8, do not apply. There are no existing economizer operations, because the air intake dampers of the heating/cooling systems are fixed in place and do not modulate. In the final analysis, new economizer operations to modulate the dampers were not recommended to be implemented because they were not found to be cost-effective.

1. OVERVIEW

A. EXECUTIVE SUMMARY This document presents a Technical Energy Audit prepared by Honeywell Building Solutions (HBS) for energy conservation measures at Grady High School, Grady Middle Vocational Agricultural School, Grady Elementary School and Grady Preschool. 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 Grady Municipal School’s staff to determine energy use and possible energy conservation opportunities. The following energy conservation measures (ECM’s) were evaluated for each building:

1 Energy policy2 Energy management system3 Lighting retrofit with occupancy controls4 Economizer retrofit to RTU's5 Building weatherization6 Computer power management7 Destratification fans in gyms8 Insulate domestic hot water tanks9 Submetering for buildings10 Variable frequency drives on RTUs11 Vending machine setback12 Building insulation13 Window replacement

Table 1: Energy Conservation Measures

See individual sections 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.

C. BASELINE SUMMARY The basis for any energy audit is the utility usage and cost for a known period of time. Below is a summary of the annual energy usage for the buildings in the District. Two years of utilities bills were analyzed, a base year chosen, and the data normalized. The fossil fuel used at Grady Municipal Schools is propane supplied by Conway Oil and the electricity is supplied by Farmers Electric Cooperative. There is one main electric meter (and several smaller electric meters) and one source for propane, therefore the campus is analyzed as a whole.

D. INITIAL SAVINGS AND INVESTMENT SUMMARY Each school building was examined in detail for energy savings potential, energy reductions were calculated, cost to implement the measures determined, and operations and maintenance effects examined. The simple payback period (SPBP) is the total investment divided by the first year savings. The SPBP may be used to rate the cost effectiveness of performing energy conservation measures. The table below summarizes all the recommended energy conservation measures. See the individual building report for details.

• CONCLUSIONS AND RECOMMENDATIONS

A. GENERAL BUILDING AND HVAC DESCRIPTIONS Building: The Grady Middle/High/Elementary Schools are a complex of interconnected buildings with an areas of approximately 40,045 square feet. The buildings are constructed with stone and concrete masonry units (CMU), stucco exterior walls, steel roof deck and slab-on-grade foundation The High School was originally constructed in 1934, with additions in 1994 and 1997. The building complex is presently used as a middle/high school/elementary & district administration facility. The Grady VoAg/Gymnasium is a complex of interconnected buildings with an area of approximately 45,415 square feet. The buildings are constructed with concrete masonry units (CMU) and wood framed walls, stucco exterior walls, steel roof deck and slab-on-grade foundation The Old Gym was originally constructed in 1937, with additions in 1960, 1973 and 1994. The building complex is presently used as a VoAg school, cafeteria, and gymnasium. Heating/Cooling/Ventilation System: The building is heated and cooled primarily by rooftop air handling units with indirect fired gas furnaces and direct expansion cooling. The units have a fixed 25% outside air opening. The units are controlled by programmable thermostats that cycle the fans on a call for either heating or cooling. During unoccupied periods the units cycle to maintain unoccupied setpoints.


02/04/11 Page 9

Lighting System: The predominant interior lighting fixture is a three lamp 32 watt four foot T8 fluorescent with electronic ballasts, along with a good number of T12 fluorescent fixtures with magnetic ballasts. Exterior lighting fixtures are predominantly high intensity discharge Metal Halide, but there are a number of other HID fixtures, including high pressure sodium, as well as a couple of mercury vapor lamps. Light levels seemed overall adequate, but with very low levels in certain places. Classroom light levels ranged from 45-60 foot-candles, however the Old Gym only had light levels of below 20 foot-candles with the old style metal halide fixtures. Most of the existing exit signs are LED except for a few incandescent signs. There were no automatic lighting controls identified. Building Envelope: The buildings are constructed with stone and concrete masonry units (CMU), stucco exterior walls, steel roof deck and slab-on-grade. Most windows are double glazed with aluminum frames. The weatherstripping and caulking is deteriorated and in need of replacement.

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


02/04/11 Page 11

Energy Usage Base Year Data: Energy usage printouts from the school’s database were provided by Grady Municipal Schools for two years, starting with July 2008 and going through June 2010. The propane delivery spreadsheet was missing the months of July 2008, August 2008 and September 2008. The total propane delivered from July 2009 to June 2010 was 28,047 gallons. From October 2008 to June 2009 only 5,325 gallons were recorded in the spreadsheet. Because of the large difference between these two years the base year of May 2009 to April 2010 was selected with a total of 19,564 gallons delivered in this timeframe. With bulk delivery fuels it is difficult to determine any one year’s usage since tank levels at the beginning and ending of each year are unknown. At least three full years of propane utility data would have helped resolve this issue. The base year utility bills were normalized. This is the most recent period for which utility data was available. Total propane delivered for the year has been distributed throughout all twelve months based on a base load for non-space heating uses and the amount of heating degree days per month. 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 3.64, build 7130. The eQUEST program uses “typical meteorological year” (TMY2) weather files rather than weather data files for a particular year. One of the challenges of energy bill analysis can be sharing of meters across multiple buildings. The entire campus is fed from one large propane tank. The PreK Building is fed from the same electric meters that feed the Main Building. All buildings were modeled in eQuest Version 3.64 and the results of this modeling allowed for the allocation of energy usage within the buildings. The annual energy use index (EUI) for Grady Municipal Schools is:

35,295 BTU/Square Foot. The annual energy cost per square foot for Grady Municipal Schools is:

$ 0.74/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 K-12 schools throughout the United States. The facility report shows a low energy intensity rating for this building and gives it an Energy Performance Rating of 88, i.e. this building’s energy usage is lower than 88% of the existing schools in the survey database.


02/04/11 Page 14

D. ENERGY CONSUMPTION BY END-USE Energy Consumption by End-use: The building was modeled in eQuest Version 3.64 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 1.6% below measured use and propane usage 0.8% below measured use.

Annual Savings and Investment Summary for Recommended ProjectGrady Municipal School

Commercial rebates are not currently offered by either the electric utility or the propane supplier. Energy Conservation Measure Interaction 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


02/04/11 Page 16

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 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.

LMS1. Energy Policy:

Existing Conditions: The Grady 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 Grady 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.

LMS3. 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 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 The life expectancy of the lighting upgrades depends on the type of fixture/bulb installed and the annual hours of usage of the lights. 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 73% of the table values to match the lighting load with the utility bills: GRADY MAIN BUILDINGS

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 25

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.

GMS5. Building Weatherization: Existing Conditions: Localized damage of the stucco exterior walls (staining and cracks) should be repaired. There is extra risk of hidden damage in such areas caused by previous or present leaks that should be sealed.

Damaged Stucco

Caulk all windows and install weatherstripping at all exterior doors. The caulking and weatherstripping will reduce air leakage through the building envelope. Air leakage represents from 5% to 40% of the space-conditioned costs. Controlling air leakage is one of the most important functions of weatherization. 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 twenty-eight exit doors are in serviceable condition. The damaged or missing weatherstripping on the majority of the doors should be replaced. The caulking around the windows, expansion joints and door frames is deteriorated and should be renewed. Old caulking should be removed and new applied, estimated to be 1,543 linier feet.

GMS6 Computer Power Management: Existing Conditions: The sixty-five identified 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 for the computer management upgrades:

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 = # (65) of PC/Monitors * Total kWh/PC =24,003 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 = # (65) of PC/Monitors * Total kWh/PC =20,301 3) Total Dollars Saved Total Dollars Saved = (Existing kWh – Proposed kWh)*Dollars/kWh = $ 307.30

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.

GMS11. Vending Machine Setback: Existing Conditions: There are two identified vending machines on campus, one cold drink machines and one snack machine.

Proposed Upgrades: Install a vending miser controller on the cold drink vending machine. The vending miser uses an occupancy sensor that will automatically set back the vending machine when the area around the machine has been vacant for fifteen minutes or so (adjustable). The controller will periodically re-power the machine to ensure the vended products stay cold. The controller senses the vending machines compressor status and will delay power-down of the vending machine until the compressor has completed its cooling cycle.

GMS12. Building Insulation: Existing Conditions: A building envelope survey has been performed to evaluate the need for building envelope insulation.. Thermal images were taken of different areas to assess current building conditions. Ceiling insulation was spot checked and determined to be R19 in most areas. However, no ceiling insulation was found in the cafeteria/kitchen, VoAg shop, and certain areas of the hallways.

Proposed Upgrades: Install R30 fiberglass ceiling insulation in the areas where there is currently no insulation. These areas are the cafeteria/kitchen, VoAg shop as well as various hallways (approximately 14,351sf). Savings Calculations: These calculations are for adding building ceiling insulation:

GMS2. 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. Mount all new space sensors at ADA approved height.

The energy management system payback exceeds the typical payback period for other 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.

SPACE X X XNOTES: 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 Propane Annual Savings=MMBTU Base – MMBTU EMS * Dollars/MMBTU Total Annual EMS Savings = Electrical Savings + Propane Savings See the eQuest report title TStat Management EEM on the following page:

Implementation Costs: The cost to furnish and install the energy management system for twenty-six rooftop units and a building management workstation with software 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 mainained 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.

GMS4. Economizer Retrofit of Rooftop Air Handlers: Existing Conditions: The building is heated and cooled by predominantly Carrier packaged rooftop air handling units with indirect fired gas furnaces and direct expansion cooling. The units have a fixed 25% outside air opening.

Proposed Upgrades:

Modify the ductwork and provide new automatic control dampers and actuators to allow for free cooling when outdoor air temperature is low. The addition of automatic dampers would also not allow outside air intake when the units cycle to maintain unoccupied setpoints. Savings Calculations:

Propane Annual Savings = (Existing MMBTU – Proposed MMBTU) * Dollars/MMBTU Electricity Annual Savings = (Existing kWh – Proposed kWh)*Dollars/kWh Total Annual Savings = Propane Annual Savings + Electricity Annual Savings

Implementation Costs: The estimated implementation costs for the economizer retrofit were provided by the air handling equipment distributor. Operations and Maintenance: This measure would increase maintenance costs since economizer controls and dampers would need to be checked and adjusted annually.

GMS7. Destratification Fans in Gyms: Existing Conditions: Both the old gym and the new gym have high ceilings. During the heating season warm air rises to the upper sections of the gyms while areas near the floor are considerably cooler. It takes additional energy to get the temperature at five feet off the floor comfortable.

Proposed Upgrades:

Install four destratification fans in each gym near the ceiling and run them continuously during the heating season. This measure is not recommended because the payback period exceeds the useful life of the fans. Savings Calculations:
