SolarWall® Solar Air Heating and Ventilation Systems

SolarWall transpired solor collector at Marks and Spencer
Europe's largest SolarWall System at 4,334m2 (46,000ft2) was designed in three colors for a new Marks & Spencer distribution center. The expected energy savings are a staggering 1.1GWh with annual CO2 reduction of 250 tons.

The SolarWall® air heating technology generates substantial economic, environmental, and work-place benefits in the form of reduced heating bills, CO2 displacement, and improved indoor air quality.

Renowned for its high efficiency & low capital costs, the SolarWall technology uses the sun’s energy to pre-heat ventilation air for  commercial, industrial, institutional, multi-residential and agricultural buildings, as well as for crop and process drying applications.  It substantially reduces traditional heating fuel expenses in a building integrated system which requires no maintenance and has a 30+ year lifespan. The SolarWall system also acts as a rain screen and is often specified for building remediation when exterior cladding needs to be replaced.

SolarWall systems have been primarily used for ventilation heating or process applications, heating large volumes of air to ambient temperature. The new  SolarWall 2-Stage System  offers higher temperature rises, making it more suitable for solar space heating.  Read more about the relationship between solar air heating efficiency and temperature rise here.

Independent monitoring data indicates that SolarWall systems can displace between 20-50% of heating fuel consumption, depending on size and application.

 

SolarWall air collector at Owens Corning
SolarWall systems have a track-record of delivering high energy performance in all projects around the world.  As an example consider Owens Corning in Toronto: generating 3600 MWh of solar energy and displacing over 600 tons of CO2/year with their 18,000 ft2 SolarWall® system. They were also awarded the Solar Thermal Project of the year award by the Canadian Solar Industries Association. Click here to read Owens Corning's SolarWall case study.

Heating can typically be one of the largest energy expenditures in the building industry. The ability of a SolarWall system to address this energy usage and to displace a sizable amount of it - and the resulting greenhouse gas emissions - explains why the technology has such a compelling return on investment, and why "from an operational point of view, [it] is the greatest technology in the world." (Quote from Desmond Raymond, Parks Canada)

 

In the late 1970s, Conserval Engineering began developing methods to reduce energy consumption in industrial and commercial applications. By the 1990s, the company had invented one of the world’s most efficient ways to harness the sun’s energy to help heat buildings of all shapes, sizes and functions – new or retrofit. The product’s apt name: The SolarWall® system.

 

Worldwide interest was sparked immediately, and the ingenuity of the SolarWall technology was recognized by organizations such as the U.S. Department of Energy, Natural Resources Canada, Popular Science Magazine, R&D Magazine, and several others.

The SolarWall technology has lead the way ever since in defining the global solar air heating industry, both scientifically and in world-wide applications, with  customers such as Ford Motor Company, NASA, 3M, Prologis, GM, Toyota, FedEx, Bombardier, the U.S. Military, and many more in over 30 countries. The high level of architectural versatility, combined with substantial energy savings and LEED point generation, have made it a popular renewable energy technology for building owners, facility managers and architects.
