Green Roofs & PV Canopies

Green-Roof Integrated Photovoltaic Canopy (GRiPV-c) is a study began through the efforts of Marc Perez, Christina Ho, and Nathaniel Wight with the support of Columbia University.  It has since evolved into a project at Bronx Design & Construction Academy, where students have taken ownership over the project.

GRiPV-c allows us to evaluate data collected from four model houses, one housing a control roof, another with a green roof, a standard fixed photovoltaic system, and a GRiPV-c system. The study is ongoing and is looking at temperature, relative humidity, and solar insolation data to qualitatively and quantitatively assess the positive impact of a combined green roof and photovoltaic canopy system on the health of the green roof vegetation, the PV canopy system efficiencies, and the efficiency of roof mounted HVAC air handling units.

Many thanks to Wade McGillis, Doherty Scientist (Lamont Doherty Earth Observatory) & Associate Professor (Earth and Environmental Engineering, Columbia University) for funding this project, and to Marc Perez and Christina Ho for kickstarting the project and providing our students with this amazing learning experience!
