According to data released today by the Solar Energy Industries Association (SEIA), five million square feet of building-integrated solar air heating collectors are now installed in North America.
These systems represent 250 MW of thermal energy and displace nearly 100,000 tons of CO2 each year from the atmosphere, says Rhone Resch, SEIA President and CEO
“Building-integrated solar air heating systems are often overlooked in the discussion about renewable energy,” he says. “We need to change that mindset. These cost-effective, energy-efficient systems can reduce, by 20 to 50%, the amount of conventional energy used for heating buildings – or for agricultural or process drying applications. That can represent a huge savings to companies, business owners, and farmers nationwide.”
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.
“By our estimates, we can create more than 50,000 new American jobs and save $60 billion in energy costs over the next 30 years by expanding the use of innovative solar heating and cooling systems (SHC) across the United States,” Resch continues. “Today, approximately 44% of all American energy consumption is attributable to heating and cooling. As a nation, it’s time to re-think our strategy for generating energy for our homes, businesses, schools, and government buildings.”
According to BEAM Engineering, a Boston-based energy consulting firm, SHC is the most efficient renewable technology for generating thermal heat, and costs are as low as 6 cents per kWh. Last year, SEIA’s Solar Heating and Cooling Alliance released a comprehensive report, detailing how SHC technologies can help to power the U.S. economy, while significantly reducing pollution.
