Energy Performance Contracting Services Green a Clean u>ta�nabl �,U Each M&V option is applicable to specific situations, and oftentimes, more than one option is possible. Multiple options may be used on a single project. The general approach to determining energy savings in these four options involves comparing the energy use associated with a certain energy consuming system within a facility, or the energy use of an entire facility, before installation of the ECM (baseline) and after installation of the ECM (post - installation). Determining energy savings for only a certain energy consuming system within a facility is accomplished with the retrofit -isolation methods. These methods allow for an accurate assessment of only the energy consumption associated with a defined measure. Ameresco bases all of its site -specific savings development and Measurement and Verification (M&V) Plans on the International Performance Measurement and Verification Protocols (IPMVP). The general approach to determining energy savings in these plans involves comparing the energy use associated with a facility, or certain energy -consuming systems within a facility, before installation of the cost reduction measure (baseline) and after installation of the ECM (post -installation). The equation for calculation of energy savings is stated below: Energy Savings = Baseline Energy Consumption — Post Retrofit Energy Consumption t Adjustments The specific savings analyses vary from measure to measure but they can all be broken down into usage before and after installation of the ECM. Sometimes the baseline usage is fixed, while in other cases the baseline is calculated based on the post -installation usage; it depends on the specific plan used to verify the performance of the measure. It is our intent to provide energy savings calculation methodologies appropriate for this project. c. Provide a Measurement and Verification Plan and Annual Savings Report from a recent project.
