Energy Savings Potential and RD&D Opportunities for Residential Building HVAC Systems

This report assesses 135 different heating, ventilation, and air-conditioning (HVAC) technologies for U.S. residential buildings to identify and provide analysis on 19 priority technology options in various stages of development. The analyses include an estimation of technical energy-savings potential, description of technical maturity, description of non-energy benefits, description of current barriers for market adoption, and description of the technology’s applicability to different building or HVAC equipment types. From these technology descriptions, we developed suggestions for potential research, development and demonstration (RD&D) initiatives that would support further development of the priority technology options.
