Solar heat for cooling
SANTA FE, N.M.--The Santa Fe Community College opened a green building in January that houses its Sustainable Technologies Center, a site I got to tour this weekend during a road trip to northern New Mexico and southern Colorado with the Institutes for Journalism & Natural Resources.
The college expects to get LEED Gold-level certification or possibly Platinum.
In a unique feature, the building's cooling system is designed to run on solar energy. Seen here is one portion of a large array of solar thermal collectors made of evacuated tubes. The school chose evacuated tubes rather than flat solar collectors because it needs to generate high-temperature water, up to about 190 degrees, which is then pumped to an adsorption chiller.
The building also has a large hot-water storage tank designed to provide enough heat to cool the building for three days. Each of the solar collectors have a small solar photovoltaic panel on them to operate the pumps.
