Abstract

The energy consumption in urban areas accompanies the anthropogenic heat exhaust, and brings a regional warming represented by urban heat island. Such a warming has not been enough clarified to contribute a further increase of the energy consumption and the carbon dioxide emission by some feedback mechanism, though the research is advanced in Japan. Especially, the sensitivity of energy use on temperature varies on purpose of energy use and depends on the urban structure. In addition, urban warming might cause a decrease of carbon dioxide emission in winter, and the evaluation through year is not easy. Nowadays citizen's attention is attracted in maintaining an excellent urban environment including urban thermal comfort and low-carbon society. Both of them have to be considered enough in urban planning process. However, it is necessary to note the case of trade-off between countermeasures on urban heat island and actions for low-carbon society.
