Heating and Cooling Control

Heating and cooling account for 45% of all energy used in the average US home. Our work on heating and cooling control advanced the state of the art from reactive thermostats to learning thermostats. We showed that reactive thermostats (which were common on the market at the time) actually increase energy usage in many homes. At the same time, we showed that learning thermostats could reduce energy usage by up to 28%, with as little as $25 in additional hardware.

Since 2008, we evaluated four different incarnations of learning thermostats, including systems for whole-house heating and cooling as well as room-level zoning. Additionally, we created several techniques to automatically configure, calibrate, and model the thermal properties of buildints. One of our heating and cooling systems is now undergoing commercial trials.
