Extensive Green Roof Ecological Benefits in Latvia

Abstract

Extensive green roof ecological benefits are studied in this paper. The research contains a brief explanation about green roof technology and green roof ecological benefits. Green roof capability to retain rainwater runoff by accumulating it in storage layers and conducting it back into the atmosphere through evapotranspiration is studied and modeled. Modeling is done in Stormwater Management Model 5.0 software. The model is based on an existing warehouse-type building located in Riga and hourly Riga climatic data of 2012. Evaluation of the model is carried out and future study fields of green roof ecological benefits are discussed.
