First commercial product meets air conditioning on the roof challenge

The Department of energy announced on 24 may Daikin McQuay rebel roof system of units is the first DOE rooftop unit (RTU) challenge. Five manufacturers - Daikin McQuay, carrier, Lennox, 7AC technologies and Rheem - participate in this challenge, high-efficiency commercial air conditioning systems to market, a DOE-issued specification for to meet the saving of energy and power. If built to meet the specification, these units are expected to reduce energy consumption by as much as 50%, compared to units built to current standards. If the specification meets all 10-20 tons of RTUs companies more than energy costs save $1 billion annually would nationwide. Five companies have until 1 April 2013, a product for which to submit independent evaluation according to the specification.

Manufacturers nationwide have a strong motivation to produce highly energy-efficient air conditioners for commercial buildings. Members in DOE commercial building energy alliances (CBEA), such as target, Wal-Mart, and other participating commercial builders have expressed an interest in the equipment that meets the new energy-efficiency specification at an affordable price. The Department of energy examines potential demo sites for high-performance products that the challenge of RTU and is precise company for a the development of analytical tools, with which the energy estimation and cost savings with high RTUs in their facilities. The specification for the RTU challenge, to promote the launch of low-cost, high-performance commercial RTU air-conditioning systems was developed by DOE technical experts and informed by industry partners.
