“…Hotels consume substantial amount of energy for airconditioning, lighting, heating, lifts, kitchen equipment, laundering and cleaning, and for the construction (Wan, Chan, & Huang, 2014) which approximately accounts for 10-15% of the turnover. Notably, within the hotel domain, a 10,000 m 2 area annually consumes energy equivalent to 1,000-ton coal, and electricity for maintaining temperature and lighting jointly records approximately 70% of the overall usage (Zhao, Ma, & Pingdao, 2012). Individually, energy consumption or running air-conditioning machines accounts about 30% of the overall energy expenditures (Ali, Mustafa, Al-Mashaqbah, Mashal, & Mohsen, 2008).…”
