Evaluation of solar thermal system integrated with campus central plant hot water loop.  Target temperature for the supplemental solar thermal array is 160'F and will eliminate most of the existing heat provided by the boilers and the central plant. CSUDH is part of the CEOP pilot to minimize GHG emissions, including improving overall energy efficiency for the campus. Analysis will be performed for the economic and efficiency opportunities in an efficient system comprised of heat pumps and solar thermal to entirely replace the existing high efficiency gas boilers.
