Proposed Session Description
The Massachusetts Maritime Academy (MMA) consists of 16 buildings comprising approximately 600,000 sf, with heating for the buildings is provided by gas fired hot water boilers in each. MMA /DCAMM have aggressive goals to eliminate carbon emissions and have undertaken a master planning effort and initial design for a distributed campus wide ground source heat pump system, combined with energy efficiency retrofits at each building. The proposed 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, it is a model that can be used for campuses or residential communities.
Learning Objectives
Quantify the benefits that come from combining energy efficiency upgrades with ground source heat pump systems.
Determine what factors need to be considered in evaluating centralized vs. distributed heat pump systems
Demonstrate the benefits of utilizing a neutral temperature energy transfer loop to connect buildings and energy sources
Explore ways that regional geo-exchange systems can be implemented in a cost-effective phased manner

Full Description
The system to be described represents a cost effective, flexible approach to improving energy efficiency and reducing or eliminating carbon emissions in distributed buildings and addresses many of the disadvantages of traditional central plants/distribution systems and fully distributed systems. It allows common geo-exchange fields to be positioned in the most appropriate locations, allows energy transfer from one building to another, and allows the use of other types of energy sources (such as wastewater, sea water or ambient air) to be integrated into the system.
