Energy Department Announces Funding to Develop Improved
Next Generation HVAC Systems.
The Energy Department announced nearly $8 million to
support research and development of the next generation
of heating, ventilating, and air conditioning (HVAC)
technologies. The R&D will focus on developing
regionally appropriate HVAC solutions that would offer
significant potential energy savings for new and
existing buildings, and on developing innovative
approaches that could replace current vapor compression
HVAC technologies and their use of refrigerants that
harm the global environment.
Currently, HVAC systems account for the largest
proportion of energy used in buildings, consuming almost
14 quadrillion British thermal units (quads) of primary
energy annually—or nearly 30% of all energy used in
commercial and residential buildings. Developing
non-vapor-compression HVAC systems could potentially
lead to an estimated 40% primary energy savings over
current technologies.
