The US Department of Energy is bringing together a diverse group of manufacturers and businesses to promote the development of advanced heat pump technology for commercial buildings. The program is called the
The Commercial Building Heat Pump Accelerator is part of the DOE’s Better Buildings, Better Plants initiative, which seeks to reduce the greenhouse gas emissions associated with heating and cooling large commercial buildings. To date, that initiative has attracted more than 900 partners who have saved more than 3.1 quadrillion Btu of energy. The savings in fuel costs alone amount to more than $18.
There are challenges, however. Heat pumps cans struggle to make heat when outside temperatures fall below freezing. One of the objectives of the DOE program is to design and build commercial heat pumps that can provide heat at temperatures as low as 20 degrees below zero Fahrenheit.
Ten commercial partners have joined the accelerator, including retailers Amazon, Ikea, Target, and Whole Foods, as well as the Los Angeles Unified School District. They have promised to be early adopters and will help test heat pump prototypes. One of the major hurdles the Accelerator aims to overcome is making heat pump rooftop units that are better adapted to the cold, a task that DOE says is more technically challenging than for residential models.
