TysklandTYSKLANDMindst 48 tyske byer giver økonomisk støtte tilgrønne tage.Omkring 35 % af alle byer har grønne tageintegreret i deres regulering14% af det totale tag areal har grønt tagMere end 86.000.000 m2 grønne tage!DHL, StuttgartDorthe Rømø


StuttgartStuttgart har over 2 mio. m 2 grønne tage. Stuttgart har siden 1986 kørt et økonomisk støtteprogram forgrønne tage og har sat krav til at alle nye tage under 12 graders hældning skal have grønt tag.For at tilpasse byen til klimaforandringer og forbedringer af miljøet. 50% støtte af omkostninger til grønnetage, max 17.9 € per m 2 .Siden 1993, krav til grønne tage på alle nye bygninger I henhold §8 i the Federal Nature Conservation Act,som kompensation for værdifuld natur og landskab.


The drainage performance of green roofs can be summarised as follows.1. A green roof will typically intercept the first 5mm and more of rainfall (i.e. provide interception storage).2. The amount of storm water stored and evaporated is primarily dependent upon the depth of the growingmedium and type of planting. In the summer a green roof can typically retain between 70-80 per cent of therunoff. [Ref: 3.18]3. In Germany it has been demonstrated that between 40-100 per cent of rainfall can be retained – dependentupon the season. [Ref: 3.20]4. Seventy-five per cent of rain falling on extensive green roofs can be retained in the short term and up to 20 percent can be retained for up to two months. [Ref: 3.21]5.As the rainfall events become longer or more intense, the positive effect of a green roof remains, as there isstill a significant reduction in peak runoff rates. This increase in the ‘time of concentration’ means that a greenroof will be beneficial throughout a wide range of rainfall conditions. [Ref: 3.22]6. The 1 above Green benefits Roofs collectively in Copenhagen mean that, by incorporating a green roof into new development, there will be areduction 2 in Dorthe amount Rømø and cost of the overall drainage infrastructure required to serve that development.London Technical Report


SchweizSom hovedregel skal grønne tage anlægges på alle nye bygninger med flade tage(Natur og Landskab Conservation Act § 9, byggeri og planlægning lov § 72).På tageflader over 500 kvadratmeter, skal substrater består af passende naturligt jordfra den omkringliggende region, og skal være af varierende dybder.Foto S.
