Energy Savings Potential and RD&D Opportunities for Commercial Building HVAC

This report assesses 182 different heating, ventilation, and air-conditioning (HVAC) technologies for U.S. commercial buildings to identify and provide analysis on 17 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.
