Description:

One of the leading areas of renewable energy applications for the twenty-first century is building integrated photovoltaics (BIPV). Integrating photovoltaics into building structures allows the costs of the PV system to be partially offset by the solar modules also serving a structural role in the building. Although PV building modules and facades are currently in use around the world, existing design tools for such systems are inadequate in terms of their accuracy and user-friendliness for building designers. Shading and reflection factors are two substantial variables in calculating system energy output. However, existing system design and simulation tools generally omit the effects of reflections from multiple surfaces and shading of solar panels.

Objective:

Our project aims to create a “user friendly” software package that may be used to accurately design BIPV systems for use by architects to predict the performance of such systems. This package would allow the user to input their building location and information on surrounding buildings and receive accurate predictions on energy production.

Approach:

The project is divided into three phases, including: i) computer modeling of the solar resource available to the BIPV system at different times of the day and year including reflection and shading effects of surrounding buildings; ii) computer modeling of the BIPV system itself; and iii) validation of the computer modeling through comparison of the simulated performance of the system with measurements made on a scaled physical model of the system.

Expected Results:

P3 aspects of the project will be incorporated into the education of students in several ways including seminars and lectures through Villanova’s Center for the Environment, through a new proposed senior elective course open to all engineering majors, and through extra-curricular activities in organizations such as Villanova Environmental Group and Villanova’s Chapter of Engineers Without Borders.
