Energy Department Announces First Product to Meet the Commercial Rooftop Air Conditioner Challenge!
Five Manufacturers are Officially Participating in the Challenge to Build Highly Efficient Rooftop Units.
May 24, 2012 - As part of the Obama Administration's all-of-the-above energy strategy to help American families and businesses save money on their energy bills, the U.S. Department of Energy today announced that Daikin McQuay's Rebel rooftop unit system is the first to meet DOE's Rooftop Unit (RTU) Challenge. Five manufacturers—Daikin McQuay, Carrier, Lennox, 7AC Technologies, and Rheem—are participating in this challenge to commercialize highly efficient commercial air conditioners that satisfy a DOE-issued specification for energy savings and performance. The companies have until April 1, 2013 to submit a product for independent evaluation according to the specification. When built to meet the specification, these units are expected to reduce energy use by as much as 50% over current standards. Nationwide, if all 10 to 20 ton RTUs met the specification, businesses would save over $1 billion each year in energy costs, helping American companies better compete on a global scale.
Manufacturers nationwide have a strong motivation to produce highly energy-efficient air conditioning units for commercial buildings. Members in DOE's Commercial Buildings Energy Alliances (CBEA), such as Target, Walmart, and other participating commercial building owners have expressed an interest in equipment that meets the new energy efficiency specification at an affordable price. The Department of Energy is evaluating potential demonstration sites for high performing products that meet the RTU Challenge. In addition, the Department is also developing analytical tools that enable businesses to more accurately estimate the energy and cost savings of using high performance RTUs in their facilities.
The RTU Challenge, aimed at spurring the market introduction of cost-effective, high-performance commercial rooftop unit air conditioners, was announced in January 2011. The specification that underpins the RTU Challenge was developed by DOE technical experts and informed by industry partners.
The final participant list was announced by Dr. Kathleen Hogan, Deputy Assistant Secretary for Energy Efficiency, at the Energy Department's first CBEA Efficiency Forum, a public stakeholder engagement event hosted by the National Renewable Energy Laboratory in Golden, Colorado. In addition to today's announcements, the forum also featured a series of information exchanges on other energy efficiency initiatives that are underway. A full meeting report will be available on the CBEA Web page in the coming weeks. CBEA is comprised of building owners, managers, and operators that collaborate with the Energy Department and with each other to develop and deploy best practices, key decision-making tools, and advanced technologies for significant energy savings.
DOE's Office of Energy Efficiency and Renewable Energy accelerates development and facilitates deployment of energy efficiency and renewable energy technologies and market-based solutions that strengthen U.S. energy security, environmental quality, and economic vitality.
