ENERGY STAR Certified
Smart Thermostats

Smart thermostats that earn the ENERGY STAR label have been independently certified to deliver energy savings.

For the average American household, almost half of the annual energy bill goes to heating and cooling – that’s more than $900 a year. Being smart about how you control your temperature settings with an ENERGY STAR certified smart thermostat will help you save money and stay comfortable in your home.

Each product uses slightly different features to help homeowners save energy, so do your research, and choose the ENERGY STAR certified smart thermostat that's right for you.

Common ENERGY STAR certified smart thermostat features may include:

  • Remote Control:
    • Using your smartphone, you can adjust the temperature in your home from anywhere with an internet connection.
  • Geofencing:
    • This feature allows your thermostat to detect when you’ve left for the day to ‘set back’ your HVAC system and save money on your heating or A/C bill. If you’re on the way home, the thermostat can automatically adjust the temperature to ensure you arrive to a comfortable home.
  • Learning temperature preferences:
    • Certain ENERGY STAR certified smart thermostats can learn your preferences automatically and establish a schedule that adjusts to energy-saving temperatures when you are asleep or away.
  • Over-the-Air Updates:
    • Your thermostat may update its software periodically to ensure it uses the latest algorithms and energy-saving features available.

Buying tips:

  • Make sure the smart thermostat you purchase is compatible with your heating and cooling system. For the very highest efficiency heating and cooling equipment, you may want a controller from the same company. (E.g. Air conditioner rated at 20 SEER or higher).
  • If your smart thermostat uses WIFI, make sure it’s reasonably close to the router to prevent periodic disconnections. If your thermostat is too far from your router, consider a WIFI range extender, which can improve overall connectivity.

ENERGY STAR certified smart thermostats are also designed to be compatible with the programs that some local utilities offer, providing home owners in their service territory with incentives to help them manage reliability.

  • Demand Response Summary Field details:
    Verdant Thermostats deliver cutting-edge demand response capabilities to commercial and multifamily properties across diverse utilities. In 2023, our success in implementing demand response spanned multiple utilities in North America. Verdant offers a user-friendly interface for load managing entities and demand response aggregators to effortlessly create and configure demand response events for multiple properties simultaneously. These events are highly customizable, accommodating different user groups. Our Demand Response API seamlessly integrates with Demand Response Management Systems (DRMS) service provider platforms, providing control to demand response firms for configuring events for end customers. This API enables units to be pre-cooled or pre-heated before an event, with options for gap periods, followed by the demand response event. Residents are kept informed with a distinct DR icon on the thermostat. They retain control, easily opting out by adjusting the setpoint. Our APIs support both batch and event-level configurations for demand response, with options to check status and delete events as needed. Crucially, our APIs also allow aggregators/utilities to create critical DR events, ensuring these cannot be opted out by residents. Furthermore, valuable feedback on event opt-outs, overrides, and load shed performance is available through the API to the Load Managing Entity.
