Hydraulic and thermal behavior of green roofs

Green roofs

Abstract

This research aims to investigate the impacts of the hydraulic and thermal properties of a green roof substrate on its performance. Two main themes are being addressed by our research team: 1) experimental determination of the hydraulic and thermal properties of the substrate, to build physical models that enable prediction of green roof behavior; and 2) collection and analysis of distributed temperature sensing data in the green roof laboratory (LIVE).
