Oak Ridge National Laboratory (ORNL) is developing and promoting the market introduction of an advanced, variable speed, air-source integrated heat pump (AS-IHP) with energy savings equal to or greater than 50% versus minimum efficiency systems. The AS-IHP would be introduced to the U.S. market by Nordyne, the cooperative research and development agreement partner. An IHP that operates at this level of efficiency can make a significant contribution to meeting the Building Technologies Office’s (BTO’s) goal of reducing building energy use by 50% by 2030.

Project Impact

The 2030 maximum adoption potential energy savings for IHPs applied to residences as estimated by the BTO Prioritization tool in May 2014 is 1482 TBtu/y with a $6.10/MMBtu levelized cost of conserved energy. Cumulative value of this energy savings potential from 2016-2030 is over $120B (based on 2010 average residential electricity cost of $0.115/kWh).
