In Bangkok exist 4 weather stations: one in rural site and three in urban sites. A recent study indicates the presence of urban heat island in Bangkok and it is increasing in terms of intensity. It reveals the maximum intensity of around 6-7°C is detected during dry season. The mean annual air temperature in Bangkok city is higher by 0.8°C than outside the city. Bangkok is the center of industries, manufacture, economy, commerce, and construction. The population is about 10 million. The reasons that contribute to the UHI effect of the Bangkok: densely build-up area, no (or few) vegetation and trees, street canyons configuration in urban configuration, the use of air-conditioning for cooling offices, higher vehicle traffic. It doesn’t seem that the authorities are aware of the urban heat island effect and there is no management of it. They are focusing on air pollution and traffic congestion, which are related to urban heat island effect. As a measure to reduce Urban heat island, I would propose to increase the numbers of trees in the streets and reduce the traffic by reducing the capacity for cars of the street. I would also propose a normative related to green buildings.
