The Effects of Urban Heat Island Phenomenon on Residential and Commercial Energy Consumption

Abstract

The purpose of this research is to clarify the effects derived from heat island phenomenon on residential and commercial energy consumption in the Tokyo area. There are many indications of the fact that energy consumption for air conditioners will increase because of the heat island phenomenon, but since energy consumption for heating and hot water supplies will decrease, there is the need to consider both effects. First, formulae estimating the energy consumption temperature based were made. On the other hand, monthly and hourly temperature distribution was estimated using mesh as units. Also, the temperature distribution estimation in the case of a less intense heat island phenomenon was carried out in the same way. With this, for each temperature distribution, the spatial distribution was estimated using mesh units and the results were compared. As a result, it was clarified that due to the occurrence of heat island phenomenon in Tokyo, there was a decrease in residential and an increase in commercial energy consumption.
