Scalable Ground Source Heat Pump Systems: Mass. Maritime Academy Case Study

The Massachusetts Maritime Academy consists of 16 buildings comprising approximately 600,000 sf, with heating for the buildings is provided by gas fired hot water boilers in each. They have undertaken a planning effort and initial design for a distributed campus-wide ground source heat pump system, combined with extensive energy retrofits. The plan consists of a neutral temperature Energy Transfer Loop that will tie various geo-exchange systems together to feed heat pump plants in each building. The proposed system is flexible, scalable and easily phased, and provides a model that can be used for other campuses or residential communities.
