TL;DRAbstract

The Alumni House-Conference Center (AHCC) on the campus of the State University of New York at Albany, combines 2300 sq. ft. of copper solar panels with a water-to-water heat pump, an air-to-water heat pump, an electric boiler and two eight thousand gallon storage tanks. The building is instrumented to provide data for the time variant electric power demands, the impact of meteorological variables, peak storage capabilities, the efficiency of the solar panels, coefficient of performance of the heat pumps and the heating system performance factor. Computer simulations of the heat budget of the AHCC have been prepared and verified. A series of economic analyses provide Return on Investment comparing the air source heat pump to the solar assisted water-to-water heat pump and using a base case of electric heating peak shaving. Incremental costs are included but the peak shaving capability was not tested. Computer analysis, unverified, indicates that the air source heat pump has a higher CO
