北海道富良野圏域を対象とした民生部門エネルギー等の需要構造分析

The realization of an energy-saving and low-carbon society that does not depend on the use of fossil fuels has become necessary due to adoption of the Paris Agreement at COP21. In order to realize an energy-saving and low-carbon society, it is important not only to reduce energy consumption by means such as insulation of buildings and introduction of highly efficiency equipment but also to reduce energy consumption in cities and regions.The aim of this study was to clarify energy demand structure of residential and commercial sectors in the Furano area in Hokkaido. First, we investigated the characteristics and energy consumption of public facilities owned by the municipalities, and we determined the energy consumption rate and monthly fluctuation of energy consumption for each building use. Next, in order to consider the area management by Furano City in the future, we estimated the urban energy demands of residential and commercial sectors and analyzed the spatial distribution characteristics of energy demand, and we clarified the area in which the use of energy in a network is effective. The following results were obtained.1) A survey of the characteristics of public facilities showed that there were many facilities that had been constructed in the period from 1981 to 1990. Since about 30 years have passed since the construction of those facilities, many facilities will require replacement of equipment in the future. In addition, there were differences between the municipalities in the state of installation of heating equipment and sources of heating and hot water supply.2) A survey of the energy consumption of public facilities showed that the energy consumption of facilities with hot baths such as public baths and heated pools was particularly large, and the annual energy consumption for hot water supply exceeded the annual energy consumption for heating in some facilities. In these facilities, conservation of energy for hot water supply as well as heating is necessary. The energy consumption rate and monthly fluctuation of energy consumption for each building use were also clarified using energy consumption data for each facility.3) The urban energy demands of residential and commercial sectors in Furano City were estimated. The annual electricity demand was estimated to be about 210 TJ, and the annual heat demand was estimated to be about 710 TJ. It was found that the annual heat demand was about 3.4-times larger than the annual electricity demand.
