Lighting systems feature 95-percent compact fluorescence lamps and LED lighting, and the windows throughout the building feature double-glazing for heat insulation. Heat-filtered film and low-flow special fixtures are used in office windows and in all sinks, respectively. Employees are encouraged to drop scrap batteries into “Scrap Battery Boxes.” In addition, the venue has recycling boxes for the recyclable waste of the guests. Outdoor lighting fixtures have time clocks, and lighting is scheduled according to summer and winter hours. Electricity consumption is reduced by heating system pumps, booster pumps and frequency inverters on the main air conditioning plants, and garden irrigation is performed by time-adjusted drip irrigation systems.
