As the country strives to meet its 2020 targets under the EU Renewable Energy Directive, one renewable heat source is being left out in the cold over what appears to be a question of semantics.rnSolar air heating was designed to heat large spaces such as offices, warehouses and factories traditionally heated by gas systems. The technology uses a Transpired Solar Collector (TSC) or SolarWall to harness the sun's energy, which is then used to pre-heat fresh air. This warm air is then drawn into the building's heating system via a series of fans, making it an active technology.
