Operation Baseline Renewable Source Term Metering Operation Commissioning Renewable Source Short Term Metering Operation Performance Period Renewable Source Term Metering Performance parameters include the measurement of equipment efficiency or output. Measurements will be • normalized with load and weather. Equipment efficiency or output will be determined during the baseline development, commissioning, and performance period. The measured data will be used as inputs for the energy The energy model needs to be tuned to past utility data to verify it is calibrated. The operating parameters include runtime which will be collected during the baseline development, • commissioning, and performance period. This measurement should be compared to the modeled output files to verify that the equipment runtime has been reduced. M&V Performance Assurance Activities Verify installation of the renewable energy system. • the renewable energy source to verify energy production and savings if practical. • Obtain Department of VA approval of all stipulated performance and operational parameters shown in the baseline • and post-installation parameter value tables. ECM: Heat Recovery System (HRUs) M&V Option: D This ECM involves the installation of heat recovery units on existing AHUs to reduce HVAC heating and cooling energy. There are a variety of options of heat recovery units; however the M&V approach is similar for all types. M&V Plan Description Option D protocol will be used to quantify the energy consumption savings associated with Heat Recovery Units. Option D is recommended due to the interactions between HVAC equipment and building loads. M&V Option Selection Rationale Heat Recovery effectiveness varies based on air flow and temperature differences. Air temperature and airflow • varies throughout the year depending on the building conditioning demand and outside air conditions. Due to the multiple interactions between HVAC equipment and building load it is recommended to perform an energy analysis model that conforms to ASHRAE Appendix G requirements.
