Smart Home Energy Management Systems

EPA has completed the development of the ENERGY STAR Smart Home Energy Management Systems (SHEMS) Version 1.0 specification, which establishes required energy-saving SHEMS features designed to deliver cost savings as well as user convenience. These features include reliable occupancy-based control of connected devices, user feedback and display of energy use data, limiting the standby power of required devices, and the inclusion of an ENERGY STAR certified connected thermostat. The specification requires periodic submission of statistical analysis of field data gathered from installations of the certified SHEMS package. EPA will use this data to affirm specification compliance, develop a performance metric, and assess energy savings potential in the coming years.

Documents relating to the development of the specification are below. Now that the specification is final, partners can find out about certifying their SHEMS packages by viewing the resources on the SHEMS for partners page. Barring small corrections to the specification, this page is not expected to be updated until development of a performance metric begins in late 2020. Partners and other interested parties with questions or concerns regarding these materials may contact SmartHomeSystems@energystar.gov.
