SolarWall®: Now honored as one of the 9 best energy inventions of the past two centuries by American Society of Mechanical Engineers (ASME). Conserval is the company that developed and commercialized solar air heating for commercial, industrial, institutional, military, multi-residential and agricultural applications. The technology we invented, known as "SolarWall", was praised by the U.S. Department of Energy as being in the "top two percent of energy related inventions", with a solar efficiency over 80%. SolarWall systems heat building ventilation air and provide solar space heating and solar process heating. The technology also improves indoor air quality as it heats fresh air. SolarWall systems deliver huge life-cycle cost savings and require no maintenance over their 30+ year lifespan. They displace 20-50% of the traditional heating load & corresponding GHG emissions. SolarWall systems are in use in 40+ countries around the world. Conserval has offices in Toronto, Canada; Buffalo, NY; and Paris, France. Conserval also has dealers around the world. Solar Air Heating is essential for GHG reduction strategies because space heating and process heat represent one of the largest use of conventional energy in commercial buildings. SolarWall systems provide a direct source reduction of GHG emissions by reducing the fossil-based heating. To date, Conserval has supplied & designed millions of square feet of SolarWall systems around the world; eliminating tens of thousands of tons of CO2 each and every year.
