Conserval is the global market leader in the renewable energy sector we created; Solar Air Heating. Since our founder John Hollick invented the transpired solar collector (branded as “SolarWall heating”), Conserval has designed and manufactured thousands of SolarWall® air heating systems worldwide for commercial and industrial buildings–eliminating tens of thousands of tons of CO2 emissions each and every year!
There are over 5 million square feet of SolarWall air heating systems on 6 continents across the globe, from Alaska to the South Pole. These systems are helping businesses and municipalities achieve their energy goals and reduce their carbon footprint.
The SolarWall technology has won numerous awards from organizations such as Popular Science, R&D 100, Renewable Energy World, the Canadian Solar Industries Association, Readers’ Choice Awards, the Toronto Construction Association, and others. The SolarWall technology has also been honored by the United States Department of Energy, Natural Resources Canada, and the American Society of Mechanical Engineers as being one of the best energy inventions.
Over the past three decades, Conserval engineers have continued to improve upon the SolarWall technology to meet each project’s design and energy requirements. The result has been a full suite of SolarWall technologies including SolarWall 2-Stage, SolarDuct® Rooftop Heating, PV/T and NightSolar systems.
Since its inception, SolarWall systems have been regularly tested by third-party laboratories so that our clients can depend on their outstanding performance. And as no SolarWall project is the same, our sales and engineering teams are experienced to support your SolarWall project through the stages of feasibility study, business proposal, design consultation, tender process, installation and start-up.
With more than 30 years of project design and management experience – and countless awards – we understand what it takes to make every SolarWall project a shining success!
Conserval has also established The SolarWall Foundation a Canadian solar charity, to support Conserval’s vision of incorporating solar heating on schools and non-profit buildings to enable children and others to experience and learn about the benefits of renewable thermal heating.
