Title: Geothermal feasibility study for City of Sonoma, California - four municipal buildings

Abstract

The City of Sonoma, located in the Northern California Wine Country, consists of several buildings which are old and historic in nature. Four of these buildings, (which shall be designated 1 through 4), totaling approximately 31,150 square feet, shall be evaluated to determine the economic feasibility of converting the existing Environmental Control Systems to water source heat pumps utilizing a natural Geothermal heat sink. Presently, on the State Park's site, there exists a warm water well which produces 250 gallons per minute of water at 73/sup 0/F. Based on utility rates forecast by Pacific Gas and Electric, installation of heat pumps in the City buildings at Sonoma does not appear to be attractive. The economic evaluation was continued until the year 2000. Pacific Gas and Electric is re-evaluating its rate forecasts and will issue a new forecast in April 1982. The high capital cost is due to retrofitting the heating, ventilating, and air conditioning equipment for the existing buildings. For a new installation, the concept of using heat pumps should be re-evaluated.
