Conserval Engineering has been delivering custom engineered renewable energy solutions for the past 30 years in over 30 countries around the world. Conserval is the company that developed and commercialized solar air heating for commercial, industrial, and institutional buildings. The technology was branded as "SolarWall®", and was praised by the U.S. Department of Energy as being in the “top two percent of energy related inventions”.

The SolarWall® technology is a building integrated system which heats ventilation air and thereby reduces the onsite energy costs for clients in the commercial, industrial or institutional sector. It generates up to 6 LEED® points, and has received commendation from both the U.S. and the Canadian Departments of Energy. The high level of architectural versatility, combined with the significant CO2 displacement and Conserval’s proven track-record, has made it a popular renewable energy choice for architects and building owners & managers. It also has the highest solar efficiency (up to 80%) of any technology on the market.

Clients include private and public sector organizations like the U.S. Military, Canadian Government, NASA, Ford, FedEx, Wal-Mart and 3M as well as over 1000 others on five continents.

It can also be used for solar night cooling in southern climates, and in conjunction with photovoltaics to create a PV/Thermal total energy system (an example of which was installed in the Beijing Olympic Village).
