Fact Sheet: Efficient Rooftop Units (ERTUs)
Nationwide, rooftop units (RTUs) make up approximately 37% of commercial buildings’ heating, ventilation, and air conditioning (HVAC) systems, and 50% of all commercial buildings’ floorspace.1 According to the Northwest Energy Efficiency Alliance, commercialized efficient rooftop units (ERTUs) can achieve 10-40% energy savings compared to standard RTUs. Nevertheless, product availability and adoption of these units remains low.
