A Seasonal Storage Solar Heating System for the Charlestown, Boston Navy Yard National Historic Park

This paper concerns the design and analysis of a solar energy system using seasonal heat storage for the National Historic Park in the Charlestown Navy Yard, Boston, Massachusetts. The system uses two existing underground concrete storage tanks filled with water as the heat store and makes use of an existing tunnel network for placement of the heat distribution pipe network. The system includes a heat pump and is designed to supply about 1000 MWH of solar heat to displace the hot water and space heat demand.
