The total size of the city of Vienna is about 41.000 hectares, of which about half, 19.000 should be ‘green’, according to zoning laws. Jurgen Preis (City of Vienna) and dr Doris Damyanovic of the local University have calculated that in Vienna 5.600 hectares of roof may be transformed into ‘green roofs and 12.000 hectares of building fassades could be made ‘green‘, thus effectively combating heat island effects’.
