Estimation of anthropogenic heat release in 23 wards of Tokyo
urban thermal environment
Construction. Civil engineering
Distributions of anthropogenic heat in 23 wards of Tokyo are estimated for two years of 1996 and 2010, which are of prime importance to discuss the effective counter-measures against urban heat island phenomenon. Anthropogenic heat discussed here includes heat release from household, commercial sector, official building, hotel, hospital, education facility, recreation sector and factory as well as automobile traffic, incineration plant and thermal power generation plant. Hourly change of heat release is calculated for cooling, heating, hot water supply and electric power supply, using the proposed unit energy consumption and the loading curve for each energy use. The variation in floor area for each building use in the future is estimated based on the recent increase rate and the urban development plants. The characteristics in exhaust heat in the wards of Tokyo are summarized and the increased rates of anthropogenic heat in the future are discussed.
