Surveys regarding the status of regulation are accomplished via the FBB. Just about a single third of all German cities have laws to assistance green-roof and rain-drinking water engineering. Eco-friendly-roof investigation institutions are located in several towns as together with Hannover, Berlin, Geisenheim and Neubrandenburg.
