Publix: RTU Evaluation

In 2011, the U.S. Department of Energy’s Building Technology Office (DOE’s BTO), with help from the Better Buildings Alliance (BBA) members, developed a specification (RTU Challenge) for high-performance rooftop air-conditioning units (RTUs) with capacity ranges between 10 and 20 tons. Daikin’s Rebel RTU was recognized by DOE in May 2012 as the first to meet the RTU Challenge specifications. A study was commissioned to compare the Rebel unit with a standard reference unit in the field. The goal of the RTU Challenge demonstration was to estimate the seasonal performance of the RTU Challenge unit and the annual savings that can be achieved by installing the Rebel unit instead of an alternate standard unit. The demonstration took place at two grocery stores located in New Smyrna Beach and Port Orange, Florida.
