Carrier Global Corporation is the first original equipment manufacturer to complete the US Department of Energy's (DOE) Commercial Building HVAC Technology Challenge in the 10–14-tonne rooftop heat pump category.
The Carrier system met or exceeded all challenge requirements, including heating capacity and energy efficiency test standards — delivering 100% heating capacity at 5°F, exceeding 70% heating capacity at -10°F and meeting or surpassing DOE's commercial HVAC efficiency thresholds.
Carrier light commercial managing director, Heidi Gehring, said this milestone is about performance that pays.
"Customers can realize lower energy bills with reliable comfort, while utilities benefit from a more efficient system that helps support grid reliability,” she said.
“This achievement reflects the work of our talented engineering and product development teams, who delivered a solution that reduces energy intensity and operating costs while helping strengthen US competitiveness in commercial buildings."
The DOE's Commercial Building HVAC Technology Challenge is designed to accelerate adoption of high-performance equipment that reduces energy use and operating costs while supporting grid reliability through lower demand.
Carrier's validated rooftop unit exceeded key efficiency and performance benchmarks in independent testing conducted by DOE, Oak Ridge National Laboratory and the National Renewable Energy Laboratory.
