A Cost-Benefit Analysis of Extensive Green Roofs
In 1994, Fritz Hämmerle published an analysis on the economic benefits of extensive Green Roofs for the very first in the international Green Roof magazine Dach + Grün. Nearly 20 years later, it is now undisputed that extensive green roofs have numerous positive effects on the environment and the physical properties of buildings. Nevertheless, today only a small amount of extensive Green Roofs have been installed in North America and this is mainly due to the high initial costs of construction and the commitment to proper long-term maintenance.
The lastest cases study (2013, Jorg Breuing) about the economics of extensive Green Roofs in the USA is now available for download.
