Connected Thermostats Specification V1.0

On June 9, 2014 EPA announced a new approach under which residential HVAC controls would be recognized as ENERGY STAR based on their ability to save energy as demonstrated by aggregate data from homes.  Minimum ease of use criteria have been dropped in favor of this approach.  Now that products need field data to participate, EPA has renamed the forthcoming product category “Connected Thermostats”.  Partners and other interested parties who would like to participate in this process are encouraged to send their contact information to ConnectedThermostats@energystar.gov to be added to the distribution list for specification development updates. This webpage will be updated periodically as new information becomes available.

Documents related to the previous ENERGY STAR Residential Climate Controls specification development have been archived and can be found on the Residential Climate Controls page.
