This dataset contains a PDF from an open house event in Carbondale, Colorado, focused on Thermal Energy Networks (TENs) and their role in decarbonizing communities. The posters provide an overview of geothermal systems for heating and cooling, the Carbondale Community Geothermal Coalition's efforts to create a zero-energy district, building energy modeling by NREL to inform system design, and the phased deployment of a thermal energy network starting with key community buildings. The file also includes examples of similar projects and gathers feedback from participants.
