Save Energy with an Energy Star Certified Thermostat

Although Energy Star has been a marker for efficient televisions and other appliances for years, it has not been applied to thermostats until this year. This is interesting because setting the thermostat properly may be the biggest energy saver in a home. Commonwealth Edison estimated that 30-35% of cooling energy use could be reduced by choosing efficient thermostat set points. Consumer Reports notes that a thermostat has the most potential of any energy-saving device to save homeowners money. So, why wasn't there a certified thermostat until this year?

Programmable thermostats have had a learning curve in recent years. Many homeowners didn't use them properly. This made it difficult to develop a standard for the thermostat itself because it was not used according to the specifications. Manufacturers have responded by making recent models more intuitive and easier to program. Based on these improvements, the U.S. Environment Protection Agency was able to issue a new standard for wifi-enabled thermostats at the end of 2016.

The Nest thermostat was the first Energy Star certified thermostat under the new rules. Like other wifi-connected thermostats, the Nest offers the ability to access the thermostat from your smartphone. The system "learns" your preferred temperatures and starts to adapt the system for maximum efficiency. It also tracks energy usage, so homeowners can adjust preferences to save money and energy.

The EPA estimates that using a certified thermostat, like Nest, can save homeowners up to 8% in energy costs per year. This amounts to at least a $50 savings per year. While that doesn't seem like a lot, the energy savings add up as more people embrace the Energy Star certified thermostats. If every thermostat worked as efficiently, the savings could reach 56 trillion BTU and offset 13 billion pounds of greenhouse gas emissions. That's the equivalent of taking 1.2 million motor vehicles off of the road. Although it may take some time to pay off the cost of a new thermostat, the increased efficiency eventually benefits home and business owners.

As part of a heating, air conditioning and ventilation remodel or new purchase, homeowners should consider an Energy Star certified thermostat. Even using the new thermostat with old equipment will lead to savings. Combining the new thermostat with a properly sized HVAC system is even better. That 8% savings will likely increase with the purchase of an appropriate HVAC system because older equipment is sometimes the wrong size or less efficient than newer models. For those not ready to purchase a new HVAC, buying an Energy Star certified thermostat is a good step in the direction of greater efficiency and cost savings.
