First of all I would like to state that Aalborg is quite far north, so I would not expect UHI to have a big effect here, warmer summer is usually greeted by very enthusiastic people :) I would say that main contributors to UHI effect here in Aalborg could be building materials. In the city centre clay products are clearly dominanting: brick and roof tiles. Moving further away from the city materials gets a bit more diverse: fiber concrete plates, lightweight building structure. Often there are large roof areas covered with black roofing felt made out of bitumen which absorbs quite a lot of sunlight and in my mind contributes to urban heat island effect quite a lot. On the other hand, it is not a very dense city, so there is a lot of green areas. In the city center there a lot of parks, and when you move just outside the city center, residential houses and private yards offer even more green for your eyes. These green areas combined with breeze coming from Limfjorden reduce the UHI effect so that it is barely noticeable. **Which are the measures you would propose?** As constructing architect my brain jumps straight to buildings. I would propose a bit more careful look into building materials, e.g. black bitumen roofing felt could easily be changed into very similar product that has a white coat on top of it, so it absorbs less and reflects more heat. Which is what we need. **Is UHI effect concerning policy making in your area?** As I have mentioned in the begining I do not believe UHI is a big factor here. As far as my experience goes with architectural projects in Denmark, other areas of sustainability has a higher priority than UHI, for example Life Cycle Impact and carbon emissions. ![Street in the city center][1] ![Street outside city center][2] ![Rural area outside of the city][3] [1]: https://edxuploads.s3.amazonaws.com/1445690978845522.jpg [2]: https://edxuploads.s3.amazonaws.com/144569111542513.jpg [3]: https://edxuploads.s3.amazonaws.com/1445691227200446.jpg
