14 Jackson Twp BOE Rosenauer Elementary School ECM #1: Lighting Controls Upgrade Occupancy Sensors Description: Some of the lights in the Rosenauer Elementary School are left on unnecessarily. In many cases the lights are left on because of the inconvenience to manually switch lights off when a room is left or on when a room is first occupied. This is common in rooms that are occupied for only short periods and only a few times per day. In some instances lights are left on due to the misconception that it is better to keep the lights on rather than to continuously switch lights on and off. Although increased switching reduces lamp life, the energy savings outweigh the lamp replacement costs. The payback timeframe for when to turn the lights off is approximately two minutes. If the lights are expected to be off for at least a two minute interval, then it pays to shut them off. Lighting controls come in many forms. Sometimes an additional switch is adequate to provide reduced lighting levels when full light output is not needed. Occupancy sensors detect motion and will switch the lights on when the room is occupied. Occupancy sensors can either be mounted in place of a current wall switch, or on the ceiling to cover large areas. The U.S. Department of Energy sponsored a study to analyze energy savings achieved through various types of building system controls. The referenced savings is based on the Advanced Sensors and Controls for Building Applications: Market Assessment and Potential R&D Pathways, document posted for public use April The study has found that commercial buildings have the potential to achieve significant energy savings through the use of building controls. The average energy savings are as follows based on the report: Occupancy Sensors for Lighting Control 20% - 28% energy savings. Savings resulting from the implementation of this ECM for energy management controls are estimated to be 20% of the total light energy controlled by occupancy sensors and daylight sensors (The majority of the savings is expected to be after school hours when rooms are left with lights on) This ECM includes installation of ceiling or switch mount sensors for individual offices, classrooms, large bathrooms, and libraries. Sensors shall be manufactured by Sensorswitch, Watt Stopper or equivalent. The Investment Grade Lighting Audit Appendix of this report includes the summary of lighting controls implemented in this ECM and outlines the proposed controls, costs, savings, and payback periods. The calculations adjust the lighting power usage by the applicable percent savings for each area that includes lighting controls.

16 Jackson Twp BOE Rosenauer Elementary School ECM #2: Condensing Boiler Installation Description: The existing HB Smith Mills 450 cast iron boiler is used as the primary source of heat for the Rosenauer Elementary School. The existing boiler is past its life expectancy of a typical cast iron boiler, however the equipment appears to be maintained in fair operating condition. Even for boilers that are close to the end of its life it is difficult to predict the point at which the boiler becomes inoperable. With the increased efficiency of the condensing boilers, the savings can be substantial. New condensing boilers could substantially improve the operating efficiency of the heating system of the building. Condensing boiler s peak efficiency tops out at 99% depending on return water temperature. Due to the operating conditions of the building, the annual average operating efficiency of the proposed condensing boiler is expected to be 88%. The existing boiler s efficiency is approximately 65%, which makes the condensing boilers an 23% increase in efficiency. This ECM includes installation of one condensing gas fired boiler to replace the existing cast iron boiler. The basis for this ECM is Aerco BMK Series condensing boilers; model number BMK 3.0. The boiler installation is based on a one for one replacement based on capacity of the existing boiler.

21 Jackson Twp BOE Rosenauer Elementary School ECM #4: Air Conditioning Unit Upgrades Description: Rosenauer Elementary has common areas conditioned by packaged rooftop units and classrooms conditioned by split system AC units. The majority of the units at the elementary schools with the exception of the split systems, are in poor condition and in need of replacement. Additionally, the split system serving the auditorium is in poor condition and should be replaced. The units currently installed are inefficient compared to modern equipment and can be replaced with new high efficiency units. New air conditioners provide higher full load and part load efficiencies due to advances in inverter motor technologies, heat exchangers and refrigerants. This ECM includes one-for-one replacement of the older air conditioning units with new higher efficiency systems. The auditorium split system requires a change in coil, from an electric heating coil to a hot water coil. It is recommended to fully evaluate the capacity needed for all new systems prior to moving forward with this ECM. A summary of the unit replacements for this ECM can be found in the table below: ECM INPUTS SERVICE FOR NUMBER OF UNITS IMPLEMENTATION SUMMARY COOLING CAPACITY, BTU/HR TOTAL CAPACITY, TONS REPLACE UNIT WITH RTU-1 Library 1 24, Carrier 50XL Infinity RTU-2 Common Areas 1 36, Trane THC Precedent Splits Classrooms 18 30, Trane XLI 20 Splits Classrooms 5 42, Trane XLI 20 Split Auditorium 1 150, Trane Voyager Total , The manufacturers used as the basis for design are Trane and Carrier.

24 Jackson Twp BOE Rosenauer Elementary School ECM #5: Vending Miser Controls Description: The Rosenauer Elementary School currently utilizes vending machines in select areas within the building. Vending machines are common within cafeteria s and faculty rooms which can be in use for a limited time during the day. The installation of the Vending Miser system will help reduce the operating hours of vending machines. Vending machines regularly operate inefficiently trying to maintain a constant cool temperature within the machine and snack machines with no cooling usually have lights that operate 24/7. The VendingMiser system incorporates innovative energy-saving technology into a small plug-and-play device that in conjunction with a passive infrared sensor regulate the operation of the cold beverage and snack machines based on occupancy and room temperature. This ECM approximates the installation of two (2) of these control systems, one (1) for the snack machine and one (1) for the cold beverage machine.

ADDITIONAL RECOMMENDATIONS The following recommendations include no cost/low cost measures, Operation & Maintenance (O&M) items, and water conservation measures with attractive paybacks. These measures are not eligible for the Smart Start Buildings incentives from the office of Clean Energy but save energy none the less. A. Chemically clean the condenser and evaporator coils periodically to optimize efficiency. Poorly maintained heat transfer surfaces can reduce efficiency 5-10%. B. Maintain all weather stripping on windows and doors. C. Clean all light fixtures to maximize light output. D. Provide more frequent air filter changes to decrease overall system power usage and maintain better IAQ. E. Turn off computers when not in use. Ensure computers are not running in screen saver mode which saves the monitor screen not energy. F. Ensure outside air dampers are functioning properly and only open during occupied mode. G. Educate staff and students on awareness of wasteful energy practices such as leaving lights on unnecessarily, leaving on of non-essential computer and/or equipment at the end of the day, leaving of outside doors/windows open as a means to control room temperature, etc 9C11003 August 2, 2011 FINAL Page 25 of 25
