The U.S. Department of Energy (DOE) Energy Efficiency and Renewable Energy (EERE) has announced the investment of $8 million for the advancement of research and the development of next-generation heating, ventilating, and air conditioning (HVAC) technologies. This supports the DOE’s goal of saving money by saving energy, and phasing down the use of chemicals that have a devastating effect on the global climate.
Currently, HVAC systems are the largest energy end-use in buildings, using almost 14 quadrillion British thermal units (quads) of primary energy annually—or nearly 30% of all energy used in U.S. commercial and residential buildings. Non-vapor-compression HVAC systems have the potential to use as much as 40% less energy than current systems.
The investment is being divided into seven projects under two major topic areas: advanced vapor compression technology and non-vapor compression technology. Advanced vapor compression systems will use highly efficient versions of the technologies that currently drive HVAC systems, but will use refrigerants that will have a minimal effect on the environment. Non-vapor compression systems will employ new technologies that use refrigerants that will not affect the environment.
