According to data released today by the Solar Energy Industries Association (SEIA), a growing sector of the industry has reached a major milestone, with 5 million square feet of building-integrated solar air heating collectors now installed in North America.
SEIA President and CEO Rhone Resch says these systems represent 250 megawatts (MW) of thermal energy and displace nearly 100,000 tons of CO2 each year from the atmosphere.
Solar air heating systems work by heating incoming ventilation air before it is brought into a building’s heating, ventilation and air conditioning system (HVAC), using wall-mounted collectors that are typically made of metal and have 30-plus year lifespans.
