“SEASONAL SOLAR THERMAL ENERGY STORAGE FOR BALANCING COLD CLIMATE GEO-EXCHANGE SYSTEMS” Cold climate geo-exchange is a requirement for realistic building decarbonization. Heating-dominant geo-exchange systems have decreasing ground heat exchanger (GHX) temperatures from year-to-year. This situation is exacerbated in cold climates where the undisturbed ground temperature is near freezing, even before...
