This study evaluates the effectiveness of climate change adaptation strategies in Berlin, Germany, on a summer day by using the urban climate model MUKLIMO_3. White coating, green roofs and a combination of both are analysed regarding their cooling ability on the 2 m-temperature. Additionally, horizontal and vertical compactness are evaluated in terms of their respective impact on the micro climate. An enhanced albedo of the urban surfaces leads to the highest cooling ability with a significant daily average cooling of 0.2 K per 0.1 increase of albedo, while green roofs have only a small cooling effect at pedestrian level. An increased vertical compactness has a cooling ability due to the higher amount of shading, enhanced horizontal compactness shows a negative impact on the micro climate due to the raised percentage of sealed surfaces and the additional urban structures that can emit additional heat during the night. All strategies show a higher effect on the daytime and a smaller influence on the nocturnal temperature.
