Roof Top Heat Pumps – Bowling Alley, Los Angeles, California

As part of Southern California Edison’s Mid-Market Peak Plus program, (where PaceControls’ retrofit solution is the sole-specified energy conservation measure), we retrofitted all eight roof-top heat pumps on a 38 lane-bowling alley.  Full IMPVP-compliant measurement and verification included 4 months of minute-by-minute data logging of both RTU power consumption and indoor space temperatures. Degree-day normalized analysis of the data indicated a 14.4% – 15% reduction in kWh, and a kW demand reduction of 18%.  The building already had its HVAC aggressively managed via its building automation system prior to the PaceControls retrofit and always maintained control during and after the retrofit.
