Energy conservation: Daytime indoor lighting comes from special "solar tubes" that channel natural light into the hotel's interior, so that on sunny days no artificial lighting is required. Lighting at night comes partly from solar power generated during the day.
節能：飯店光源採太陽能的特殊設計，晴天不必開燈，夜間則部分利用白天儲存的太陽能來照明。
