Energy Efficient HVAC Packages for Existing Residential Buildings

This project will develop and demonstrate innovative pre-commercial, cost-effective retrofit packages for cooling and ventilating single family homes. Energy savings, occupant behavior and indoor air quality (IAQ) will be measured for two specific retrofit packages that each includes three innovative technologies: (1) building envelope sealing, (2) two variants of smart mechanical ventilation that include pre-cooling strategies, and (3) compressor-free evaporative air-conditioning. Furthermore, barriers and opportunities towards adoption of such retrofits will be identified through stakeholder interviews.
