Solar Labs, US
Commercial building rooftops present a vast, untapped landscape for solar energy. If this bounty is harvested efficiently, energy requirements in these buildings could be lowered significantly for cost savings and greenhouse-gas reductions. Solar Labs has designed and is commercializing a roof-mounted solar air heater that delivers auxiliary heat to buildings during winter months. The extreme efficiency and lack of conversion or transmission losses make this technology among the most cost-effective in the renewables sector. Solar Labs goal is to license the technology to pre-engineered building manufacturers. The technology is particularly cost-effective for buildings located in areas that experience four-month winters (40+ latitudes). A demonstration-phase project was retrofitted to a metal building in winter 2008.
