Advanced thermostats are now Energy Star-approved (again)

Last week, it was announced that Nest thermostats have earned Energy Star certification, marking the first time a wi-fi enabled thermostat had earned that status. But it’s not the first time that thermostats with advanced features have been on the Energy Star radar. In 2009, the EPA suspended the designation for programmable thermostats when research uncovered minimal energy savings from these devices because they were often either unprogrammed or incorrectly programmed. But thermostats (and the Energy Star requirements for them) have come a long way in the intervening years and hopefully customers will have an increasing variety of products to choose from that carry the Energy Star logo.
