Analyze real-world communicating thermostat (CT,) interval, and home energy audit data to successively refine home thermal response models to accurately estimate home physical parameters, i.e., whole-home R-value and ACH50, that correspond to insulation and air-sealing retrofits in increasingly complex situations.
Project ObjectiveDevelop a tool for utility energy efficiency (EE) programs that analyzes communicating thermostat (CT) data to automatically identify and quantify the benefit of targeted and customized retrofit opportunities
Customer and Utility Benefits
- Increase the uptake of home energy assessments
- Increase deployment rate of the target energy conservation measures (ECMs)
- Decrease the cost of EE programs via targeting
- Reduce retrofit performance risks using home-level remote EM&V
- Increase customer engagement
- Enhance the value proposition for CTs – projected ~25MM installed circa 2019
Communicating (also known as “smart”) thermostats deployed in most homes identify high-impact opportunities to reduce HVAC energy consumption and ensure retrofit performance.
