Green-Roof Integrated Photovoltaic Canopy (GRiPV-c) is a study being conducted by Marc Perez, Christina Ho, and Nathaniel Wight from Columbia University.

GRiPV-c aims 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 students at Smith Campus students (Ashley Grant, Brandon Harvey, Michael Smith, William Alicea, Jared Hatcher, Marco Dwyer, Warrick Balfour) for their hard work to build the models and for their high level of motivation and excitement about the project.

Many thanks to Bronx Design & Construction Academy students (Noel Cruz, Elton Hollingsworth, and Jeremy Urena) for picking up the experiment and assisting in collecting and analyzing the data!

Additionally, many-many thanks to Wade McGillis, Doherty Scientist (Lamont Doherty Earth Observatory) & Associate Professor (Earth and Environmental Engineering, Columbia University) and Columbia University for funding this project!
