Green Roofs As a Tool For Solving The Rainwater ..

Jeroen Mentens, Dirk Raes, Martin Hermy ? section of Land Management, Laboratory for Forest, character & Landscape Research, KULeuven, Vital Decosterstr. 102, B-3000 Leuven, Belgium current 5 January 2004; received in revised form 15 February 2005; certain 22 February 2005 lendable online 13 May 2005 see During the kick the bucket ii decades, a large do of research has been create in German on the lessening of rain water overflow for several(predicate) types of roof fountaining. This paper analyzes the original measurements reported in 18 publications. Rainfall overspill descents for an one-year and seasonal age graduated table were obtained from the analysis of the available 628 selective information records. The derived empirical models allowed us to task the surface flood from variant types of roofs, when roof characteristics and the annual or seasonal precipitation argon given. The annual pelting overflow relationship for green roofs is strongly determined by the information of the substrate layer. The retention of rainwater on green roofs is pass up in winter than in summer.

The application of the derived annual relationship for the region of Brussels showed that elongated roof color on just 10% of the buildings would already results in a runoff reduction of 2.7% for the region and of 54% for the individual buildings. dark-green roofs place therefore be a useful tool for diminution urban rainfall runoff. all the same in assign to deliver a greater result on overall runoff they should be accompanied by other promoter of runoff reduction and/or water retention. © 2005 Elsevier B.V.
