An overarching goal of this project is to model the interaction between a green roof and rooftop PV system. This joint model will allow for exploration of scenarios that could alter the temperature of the roof, the output of the panels, and the runoff retained by the green roof. Individual models are being developed before coupling them into a comprehensive roof top model. Three sub-projects are ongoing or planned for this purpose:
1. Evaluating potential efficiency gains of solar panels placed on vegetated roofs (M.S. Thesis)
In this project, the System Advisor Model (SAM) will be used to explore the range of temperature and albedo changes that could alter the solar panel efficiency.
2. Coupling energy and water balance in a green roof through evapotranspiration
With novel adjustments to the Penman-Monteith evapotranspiration equation, this project models the influence of changes in vegetation type (surface resistance) on the green roof energy and water balance using experimental data.
3. Establishing a comprehensive multi-functional green roof model
Using a python wrapper, this project will combine the previous model into an open-source rooftop model, available to test scenarios of current and future climate and evaluate total net benefits of a multi-functional green roof.
