2016 NEEA Communicating Thermostat Market and Technology Research
EQL Energy along with Mike Lubliner from Washington State Energy Office and Gregg Hardy provided the Northwest Energy Efficiency Alliance with the a regional market assessment of energy and capacity saving potential of engaging web-enabled communicating thermostats in residential homes with electric space heat. The technical achievable potential is 153 MWa and over 2,000 MW of winter capacity reductions.
Some surprising results included:
- Electric resistance HVAC sales continue to grow 1%/year. For instance, Cadet Heat, Inc. continues to sell 200,000 baseboard and wall heaters in the PNW.
- Ductless Heat Pumps only achieve 50% of potential home savings because of 1) auxiliary resistance heat, and 2) increased comfort and air conditioning in summer.
- Web-enabled communicating thermostats could address these issues by:
- controlling secondary heat
- Improved sensors (e.g., auto-away)
- Combined equipment control and coordination (e.g,. resistance heat lockout above certain temperatures.)
The table below shows some of the technically achievable potential in Northwest energy and capacity savings .
- perform lab research on WCT ability to control multiple devices, e.g., DHP, line voltage thermostats, etc.
- Field studies to include consumer behavior.
