Evaluating the measured results of demand-control strategies in new and retrofitted commercial buildinga

There has been little evidence that demand-control techniques have succeeded in reducing power demand, or that their implementation has been cost-effective. To fill this gap, the measured results of demand-control in new and retrofitted commercial buildings are being compiled. Various demand-control strategies and their impact on power and energy consumption, and a methodology for analyzing the measured performance of these demand-control strategies are described. Four performance indicators are developed and applied to 17 buildings that have implemented demand control. The limitations to using whole building data to evaluate peak power performance in the commercial sector are discussed.
