It is interesting to see the big differences between the rural areas and the cities. I’m curious to what the situation would be in Denmark. 2.Which are the main UHI effects that you can identify in your area? I think higher vehicle emissions around the centre and the often asphalt roads can add to the UHI effect in Århus. Also, during winter not well enough insulated older buildings and necessary heating use can increase the UHI effect. Info on UHI in Aarhus: On July 1st 2015, the temperature in Århus was 24 degrees C, and the same for villages Tirstrup and Risskov. The same temperatures count for every single day. The weather reports are not detailed enough to show a significant effect of UHI. ![Aarhus centre][1] The first picture was taken in the city centre of Århus. The building heights are constant, a lot of reflecting surface, plus the street canyons are relatively wide. This would assume a higher radiation encapture between the buildings. ![Aarhus forest background][2] In the second picture you can see the surrounding forest of Århus in the background. The trees’ leaves will block out a lot of solar radiation, the trees don’t give off heat and it would be difficult to find an UHI effect here. 3.Which are the measures you would propose? Although it is Denmark, and urban heat islands would sometimes actually be preferred, a measure I could propose is to bring more trees into the streets, that are now mostly empty. Also I would suggest to continue in the general building ways, so no clusters of high-rise buildings, and keeping space for parks. 4.Is UHI effect concerning policy making in your area? Unfortunately I haven’t found any information about UHI policymaking in my area.
