90% of drinking water is covered, supplied by groundwater. Groundwater can also be provided to guests in times of disaster. Approximately 450 m³ of drinking water is produced from this groundwater daily.
With the aim of reducing the consumption of natural gas and petroleum, used as fuels for heat sources, it transforms steam produced in the co-generation plant into hot water and temporarily stores it. When necessary, retransforms hot water back into steam to supply an appropriate amount of steam.
The ice-based heat-exchange plant creates ice using late-night power. This ice is used for the daytime cooling system. By reducing electricity consumption, CO2 emission is also reduced. This leveling of electric power load helps reduce cost for the air-conditioning machinery.
