Extensive Green Roof Ecological Benefits in Latvia

Rihards Rušenieks, Agris Kamenders

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.
