MEASUREMENT & VERIFICATION DETAILS <br />OPTION A — LIGHTING EFFICIENCY AND CONTROLS <br />A. Overview of M&V Plan, and Savings Calculation <br />B. Energy Savings Calculations <br />C. Key Parameter Measurement Strategy <br />D. Parameter Estimates <br />E. Cost Savings Calculations <br />A. Overview of M&V Plan, and Savings Calculation <br />Savings in this section are determined by using an "Option A: Retrofit Isolation — Key Parameter <br />Measurement" approach as described in the International Performance Measurement & Verification <br />Protocol (IPMVP Volume I, EVO 10000-1:2012). The remainder of this section describes the energy <br />savings calculations, key parameter measurements that will be conducted, parameters that will be <br />estimated and those values, and how cost savings will be calculated. The energy and cost savings that <br />are determined using this approach will be the annual savings values used for each year of the <br />Performance Period. <br />B. Energy Savings Calculations <br />Provided within this section is an explanation of the calculations that will be used to perform energy <br />savings calculations for this verification method. <br />Equations and Analysis of Energy Savin s <br />Savings are calculated as the difference in energy usage from the baseline conditions, and the <br />Performance Period conditions. <br />For energy demand, the demand savings will be determined for each fixture and summed for all fixtures <br />that will be retrofitted using the following formula: <br />Equation 1 — Energy Demand Savings <br />l <br />Dsave — �LIEPre — EPosr1 X A <br />i=1 , <br />Where, <br />Dsave = Demand savings <br />n = Number of fixtures <br />Epre =Power usage of the baseline lighting conditions <br />Epos, =Power usage of the Performance Period lighting conditions <br />M = Equivalent months of annual demand savings <br />For energy consumption, the energy savings will be determined for each fixture and summed for all <br />fixtures that will be retrofitted using the following formula: <br />Equation 2 — Energy Consumption Savings <br />if l <br />Esnve — LEPre X HPre — EPosr X HP., J <br />1=� p <br />Where, <br />Esave = Energy savings <br />Energy Solutions Proprietary and Confidential <br />v102811 Y0 <br />
