During the 13th Five-Year Plan period, the energy conservation and emission reduction have been vigorously promoted, there is room to improve the energy consumption benchmarking value and influencing factors in Shanghai local standard DB31/T 551-2011 Rational use of building energy guide for star-rated hotels. The main factors affecting the energy consumption benchmarking are occupancy rate, density of guestroom, laundry amount intensity and dinning amount intensity. Through the analysis of large sample data, it is concluded that the energy consumption per unit floor area increases by 0.2% to 0.4% for every one percentage point increase in the occupancy rate of different star-rated hotels, and the energy consumption per unit floor area increases by 1.7 kg/(m2·a) to 3.4 kg/(m2·a) for every 1 set per 1 000 m2 increase in the density of guestrooms. It is suggested to set correction thresholds for laundry amount intensity and dinning amount intensity, which are 10.0 kg/m2 for the laundry amount intensity and 6.0 persons/m2 for the annual dinning amount intensity respectively, and deductions should be made according to the actual situation when the correction threshold is exceeded.
