The Natural Choice for Fresher AirRenewAire products represent the final step in energy efficient building and sustainable design. As commercial buidings and homes have become more air tight, the need for energy efficient ventilation has become increasingly important. RenewAire is uniquely qualified to provide this critical indoor component.The Pioneer And The LeaderMore than 30 years ago, RenewAire became the first U.S. manufacturer to produce a static plate Energy Recovery Ventilator (ERV). Its elegantly simple energy exchange technology offers positive air stream separation, which provides healthy, fresh air while recapturing heat or coolness normally wasted in an exhaust air stream. With over 160,000 units in operation and growing, RenewAire is one of the largest manufacturers of ERV technology in North America, offering fifth-generation ERV core technology with industry-leading features in the broadest available line of ERV models. Born GreenWith a founding mission of maximizing energy conservation, RenewAire makes energy efficiency and sustainability the prime design criterion for every product we make and sell. Our ERVs are manufactured in Madison, WI in one of the few buildings worldwide to be LEED and Green Globes certified, as well as having achieved Energy Star Building status. Our annual success is measured by the number of people enjoying fresher indoor air thanks to our ERVs, and the amount of energy our products save in the process.
