Predicting the Interaction Between Building Integrated Photovoltaics and the Built Environment: Opportunities and Challenges

Ryan Danks, Goncalo Pedro

Abstract: To achieve ambitious sustainability goals, many building designers are turning to photovoltaic (PV) systems to provide onsite energy production. Increasingly, PV systems are integrated into the building envelope itself. Aside from the non-trivial task of simulating energy generation potential on complex facades in urban environments, understanding the effects of building integrated PV (BIPV) systems on their surrounds also needs to be understood early in the design process to prevent potentially problematic impacts. This paper investigates how modelling inputs influence the accuracy of energy production simulations, to ensure robust predictions which account for the effects of shading and micro-shading of the panels at short time scales in complex urban environments. The potentially problematic secondary effects of BIPV, including visual glare, snow accumulation, and thermal impacts on people and/or ventilation systems are introduced, and approaches to predict and mitigate those impacts are discussed.
