The dra<strong>in</strong>age performance of green roofs can be summarised as follows.1. A green roof will typically <strong>in</strong>tercept the first 5mm and more of ra<strong>in</strong>fall (i.e. provide <strong>in</strong>terception storage).2. The amount of storm water stored and evaporated is primarily dependent upon the depth of the grow<strong>in</strong>gmedium and type of plant<strong>in</strong>g. In the summer a green roof can typically reta<strong>in</strong> between 70-80 per cent of therunoff. [Ref: 3.18]3. In Germany it has been demonstrated that between 40-100 per cent of ra<strong>in</strong>fall can be reta<strong>in</strong>ed – dependentupon the season. [Ref: 3.20]4. Seventy-five per cent of ra<strong>in</strong> fall<strong>in</strong>g on extensive green roofs can be reta<strong>in</strong>ed <strong>in</strong> the short term and up to 20 percent can be reta<strong>in</strong>ed for up to two months. [Ref: 3.21]5.As the ra<strong>in</strong>fall events become longer or more <strong>in</strong>tense, the positive effect of a green roof rema<strong>in</strong>s, as there isstill a significant reduction <strong>in</strong> peak runoff rates. This <strong>in</strong>crease <strong>in</strong> the ‘time of concentration’ means that a greenroof will be beneficial throughout a wide range of ra<strong>in</strong>fall conditions. [Ref: 3.22]6. The 1 above <strong>Green</strong> benefits <strong>Roofs</strong> collectively <strong>in</strong> <strong>Copenhagen</strong> mean that, by <strong>in</strong>corporat<strong>in</strong>g a green roof <strong>in</strong>to new development, there will be areduction 2 <strong>in</strong> Dorthe amount Rømø and cost of the overall dra<strong>in</strong>age <strong>in</strong>frastructure required to serve that development.London Technical Report
