Abstract: This paper examines the retrofitting of low-cost, passive three-dimensionally (3D) printed air-ducts upon the energy usage and production of roof-mounted building integrated photovoltaic (BIPV) systems. BIPV systems are an increasingly popular method of generating electricity, however, the efficiency of photovoltaic (PV) panels is negatively affected by high operating temperatures. Additionally, many residences do not have properly ventilated attics, which increases PV panel temperatures while decreasing airflow. Air-ducts can lower photovoltaic panels operating temperatures and increase airflow in a home's attic. This study investigates the overall heating and cooling loads after retrofitting an air-duct vs. a baseline building in three climate zones. The results demonstrate a 2.7% energy savings compared to the current baseline design by adding a novel passive BIPV modification.
