Green building standards like the Living Building Challenge promote the construction of net-zero energy buildings. In order to meet these standards, alternative heating and cooling methods become necessary, especially for designs with high glazing percentages. The design and analysis of a low cost heating and cooling system with 100% solar fraction is being investigated to address this scenario. Following a literature review and visits to two Living Building Challenge certified buildings, a preliminary building configuration was created for the Living Lab project at Olin College of Engineering. Thermal modeling was conducted on three basic building configurations with different amounts of solar glazing to determine the peak thermal loads for the project‘s temperate building site. Future analysis will be performed using Green Building Studio and eQuest software to identify energy saving strategies and confirm a final proposed design.
