Condensing Rooftop Unit Field Study

Energy 350 was selected by the Northwest Energy Efficiency Alliance (NEEA) to install and monitor the performance of four custom condensing gas rooftop units (C-RTUs) over the 2018/2019 heating season. We managed the installation of the four C-RTUs across Oregon, Washington, and Idaho which all showed greater than 11% gas savings relative to a standard efficiency unit. Some of the most interesting results from the field trial came from the site selection observations, installation challenges, and surveying building owners and installing contractors. Based on these results, NEEA is continuing with efforts to remove market barriers and increase adoption of C-RTUs in the Northwest.
