All Rooftop Units (RTUs) Are Convenient, But Most Are Wasteful

Rooftop units (RTUs) supply heating and/or cooling to meet the thermal comfort requirements of commercial buildings. Inherently convenient, RTUs package heating, cooling and ventilation equipment together in a space that is accessible to technicians without taking up precious real estate. However, most RTUs are using much more energy than necessary. Efficient gas RTUs incorporate a combination of energy-saving features to reduce annual HVAC energy use by up to 40%.
