SPECIFIC MEASUREMENT AND VERIFICATION PLAN <br />"OPTION A" <br />FOR HVAC CONTROLS UPGRADE <br />Introduction <br />This Measurement and Verification Plan (M&V) is specific to the energy management system upgrades at the sites <br />listed in the Table of Recommended Measures located at the beginning of this Attachment. <br />M&V Protocol <br />For this FEM, IPMVP Protocol — Option A shall be utilized. This option shall provide for the measurement of at <br />least one variable pre and post retrofit with other variables allowed for stipulation. The cooling and heating setpoints <br />during occupied and unoccupied modes of the HVAC equipment will be verified and documented. For this retrofit, <br />field data shall be collected which includes, unit counts, unit tonnage, nameplate horsepower, efficiency rating, <br />operating schedules, cooling and heating temperature setpoints for each HVAC system. <br />Stipulated Values <br />Hours of operation and heating/cooling load factors are stipulated for purposes of M & V. Please refer to the <br />Attachment C, HVAC Standards of Operations for specific existing and proposed operating hours for each HVAC <br />unit or area. Stipulated values are agreed to by Purchaser. <br />Calculations <br />The calculations for the baseline energy consumption and post retrofit savings provide the basis for the overall <br />financial viability of these FEM's. Post -retrofit operating schedules and trend reports will be used to verify the inputs <br />such as operating hours, cooling/heating temperature setpoints that are used in the calculations to validate the savings. <br />The following equations summarize the calculation of savings: <br />Electric (kWh) Savings <br />The electrical usage reduction of this FEM is determined by applying the stipulated runtime reduction to the <br />calculated energy usage of the HVAC unit. <br />(Size of HVAC unit) x (Unit efficiency) x (Stipulated load factor) x (Existing annual operating hours — Proposed <br />annual operating hours) = kWh savings <br />Natural Gas (Therms)Savings <br />The natural gas usage reduction of this FEM is determined by applying the stipulated runtime reduction to the <br />calculated energy usage of the HVAC unit. <br />(Size of Heating unit) x (Unit efficiency) x (Stipulated load factor) x (Existing annual operating hours — Proposed <br />annual operating hours) = Therm savings <br />Dollar Savings <br />After calculating the kWh saved and the Therms saved, the specific facility's average cost per kilowatt hour and <br />the average cost per Therm of natural gas shall be used to determine dollar savings. <br />(kWh saved) x (average kWh rate) = $ kWh saved <br />(Therms saved) x (average Therm rate) = $ Therms saved <br />($ kWh saved) + ($ Therms saved) = Total dollars saved <br />Attachment A <br />*CLIMATEC' Page 12 of 13 <br />MFRGING BUIL-DINGO & TFC.HNQL_LK!v <br />
