**2_Now that you saw the significant effect of UHI in the US cities, can you provide data and information for your own place of residence?** On average, the temperature in Brussels is 2.5 degrees higher than in the countryside. In some neighborhoods like Molenbeek and Anderlecht ... the difference can be up to 5 °. (MRI the international royal institute). I’ve searched two images (first picture Brussels, second picture Hoeilaart, a rural area near Brussels) that could indicate some of reasons that contribute to the UHI effect of the city; - Few green areas in the city. - Urban materials, for example asphalt, that absorb rather than reflect the sunlight. - The great amount of buildings increases the number of vertical surfaces, which absorb and reflect the sunlight as well as obstruct winds that can contribute to decreasing the temperature. - All heat emitted by human activities: heat release from traffic, heating of industrial and residential buildings and industrial processes, among others, contribute to the urban energy balance. Anthropogenic heat can significantly contribute to the surface fluxes in densely populated cities. **3. Which are the measures you would propose?** - Use scenario for the future urbanization of brussels together with climate change. - Study the effect of some mitigation options; vegetation,white roofs,green roofs, compact city or sprawl city. - Alternative building materials - Reduced air conditioning - Improve public transportation and the number bicycle lanes. **4. Is UHI effect concerning policy making in your area?** For several years, Brussels has been involved in a large number of activities aiming to meet the environmental challenges specific to a modern city-region. The objective: for Brussels to become a model in the coming years with regard to sustainable development. Brussels-Capital Region has chosen to develop several courses of action involving all areas of life in the community. In signing the Covenant of Mayors, Brussels has committed itself, with 1600 other signatory cities, to reducing its greenhouse gas emissions by 30% by 2025, thus exceeding the European objective of a 20% reduction in 2020. Significant resources are also devoted to combating environmental pollution: water purification, stricter standards for radiation from transmitting antennas for mobile phone networks, combating pollution peaks, waste reduction, etc. Action toward a sustainable city also involves supporting hundreds of local initiatives of citizens who are active everyday : sustainable neighbourhoods, collective the creation of vegetable gardens and neighbourhood composting, etc. Brussels ![saisir une description de l’image ici][1] Hoeilaart ![saisir une description de l’image ici][2] [1]: https://edxuploads.s3.amazonaws.com/14502160784822022.jpg [2]: https://edxuploads.s3.amazonaws.com/14502161542297801.jpg
