Green Power, a group of enthusiastic volunteers have been running educational seminars, scientific tests and informing the public on various environmental problems in Hong Kong. Using their information from a study in 2012, in rural areas, the annual mean temperature rose from 0.08°C to 0.28°C. In urban areas, the Hong Kong Polytechnic University found the urban head island value in urban areas was about 2.17°C. ![Rural Area ][1] ![Central ][2] The difference in urban areas from rural areas is 7-8 °C. This is more most notable in winter. **Part 3** To introduce more legislation over road use, increase prices on tolls or create a CBD boundary where it reduces the traffic in city areas. Increase connections with the rural areas of Hong Kong, such as the rural urban fringe in North East North Territories area where more developments are occurring. Create more work opportunities in the area to reduce commuting to the city centre. Create more river channels or natural spaces to decrease heat island. Hong Kong has a department of Land Surveying and Geo-Informatics which monitors this information. Here are some points on how to improve: • In Hong Kong due to our lack of usable land we tend to do reclamation. This intensifies the heat island effect in urban areas (as it is where reclamation tend to occur). One way to deter from reclamation is to slowly use land which is retained for country parks or later planning. Of course, it is a controversial topic but with proper legislation and regulation it can be used wisely. • Building materials highly affect the heat island effect. Usually they are built out of concrete, stone, metal and asphalt which has low reflectivity. These materials tend to absorb heat. One way to reduce is the use paler colours, such as white and temperature natural elevates. **Part 4** Current Policies: We currently have a new CBD development called “Energizing Kowloon East” where the government is a pilot to explore the feasibility of developing a smart city. Various research firms were investigating the phenomenon and will be working to reduce the UHI effect in this to-be newly developed area. They will be observing factors such as Sky View Factor (SVF) which is the fraction of sky visible from the ground up, height and density of buildings, ventilation corridors and Frontal Area Index. The government also included building incentives for developing sustainable buildings. A BEAM certification was introduced as well as the international LEED certification. Sustainable Building Design Guidelines (APP 152) were also introduced by the Buildings Department. In this guideline a specific requirement of communal podium gardens and building set back are introduced. These guidelines are aimed at reducing UHI specifically through various experiments of fluid dynamics. ![New Project by Aedas][3] ![New Project!][4] [1]: https://edxuploads.s3.amazonaws.com/14451854064174085.jpg [2]: https://edxuploads.s3.amazonaws.com/1445185439261523.jpg [3]: https://edxuploads.s3.amazonaws.com/14451856757358522.jpg [4]: https://edxuploads.s3.amazonaws.com/14451857037862833.jpg
