ENERGY STAR SHEMS Draft 1 Version 1.0

On April 12, the U.S. Environmental Protection Agency (EPA) held a webinar to review Draft 1 of Version 1.0 of ENERGY STAR Smart Home Energy Management Systems (SHEMS). The intent of this program is to recognize smart home system packages that save energy and deliver cost savings and convenience by providing reliable vacancy detection, limiting standby power of connected devices, and providing users feedback on the energy impact of their settings. The key concept is that smart devices plus occupancy information plus automated services equal energy savings.
