Control Strategies to Reduce the Energy Consumption of Central Domestic Hot Water Systems

Description

Domestic hot water (DHW) is the second-largest energy end use in U.S. buildings; it is exceeded only by space conditioning. In this study, the U.S. Department of Energy's Building America research team Advanced Research Integrated Energy Solutions installed and tested two types of recirculation controls in a pair of buildings to evaluate their energy savings potential. Demand control, temperature modulation (TM) controls, and their simultaneous operation were compared to the baseline case of constant recirculation.
