Energy Consumption Analysis and Proposed Retrofit of Gilbert-Addoms Dorm


Fall 2016 - Spring 2017


To investigate the incorporation of green building concepts into college dormitories, we examined the current state of energy consumption in a Duke University dormitory. Our focus was Gilbert-Addoms (GA), a 60 year old, 68,625 square foot building. To mediate inefficient fenestration, window parameters were measured, heat transfer models were developed using principles of physics and thermodynamics, and a thin film and sealant retrofits were proposed and analyzed by the same models. Next, to incorporate renewable energy, solar heat gain was calculated from historic solar resource data, and a solar photovoltaic/thermal hybrid system was proposed. Retrofit variables were plugged into the model, and compared with the building’s past energy consumption data. The results proved cost-effective in the long term while simultaneously reducing greenhouse gas emissions, demonstrating that retrofits offer feasible potential as Duke and other universities pursue future sustainability goals.
