Packaged AC/Gas Fired Heating – Public Charter School, Philadelphia, PA

After retrofitting the gas/electric package units on this city school, we conducted IPMVP-compliant measurement and verification of the savings. We used a representative sample by data logging the energy consumption of 4 RTUs and the temperatures of the interior spaces (e.g., classrooms) which they conditioned.   Like all our IPMVP-compliant M&V work, the analysis included weather normalization and matching periods of similar occupancy.  The results indicated 14-19% kWh savings for cooling and 15-21% therm savings for heating.
