Using Communicating Thermostats to Automate, Customize, and Scale Home Energy Assessments

Scaling-Home-Energy-Assessments.jpg

Project Overview

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 Objective

Develop 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

Ultimate Vision

Communicating (also known as “smart”) thermostats deployed in most homes identify high-impact opportunities to reduce HVAC energy consumption and ensure retrofit performance.
