This project will investigate the feasibility of using geopolymers in geothermal exchange systems for residential and commercial applications. A geothermal exchange system utilizes the earth as a heat source in the winter and a heat sink in the summer. This will be one of the first geothermal exchange systems on campus, and a novel application of geopolymers within the proposed Living Laboratory (LL) at the Energy Farm (see below) to enhance thermal exchange. Phase 1 of this project involves using geopolymers in the floor slab of a greenhouse area in the LL to improve the thermal transfer from the geothermal loops installed in the slab and the ambient environment in the greenhouse. Geopolymers are chemically bonded ceramics that have the potential to replace concrete and provide better thermal exchange and a more environmentally friendly construction material because of the significantly lower greenhouse gas emissions and energy usage during its production.
