This International Office Building of the Year and recipient of a BOMA Earth Award has utilized MACH Energy as part of a "continuous recommissioning" strategy to daily review and evaluate building operations. Initial savings programs were put in place in the late summer / early fall of 2007 to reduce peak demand usage during hot weather. Using the daily economic feedback mechanism provided by Alerts from the MACH Asset•Manager, building operations was able to reduce daily peak demand by employing pre-cooling after hot weekends, savings thousands of dollars.
During the next year, the building continuously adjusted building start times to match ambient weather conditions. This strategy yielded savings over the building energy management system (EMS) optimized start programming. The building worked to identify and eliminate any operational anomalies that could impact electric usage, reviewing the previous day's electric usage against historical norms that were calculated and displayed in the MACH Energy system. This daily feedback process and resulting changes in the various EMS and equipment settings achieved efficiency improvements to building operations. The strategy of continuously benchmarking the building against itself using MACH Energy reduced electric expense by greater than 7% in 2008 after adjusting for the effects of weather, occupancy and rate changes.
