Study on Energy Use Characteristics of Hotel Buildings in Shanghai

Abstract

This paper presents statistical energy use characteristics of hotel buildings in Shanghai. Building information and energy consumption data had been collected by field survey of 45 star hotels. The results show that the hotels were mostly built after 1990s, and the area of guest room accounts for more than half of the gross floor area. The breakdown of energy use shows that electricity is the main energy source, which accounts for 75% of total energy consumption. The annual average energy use intensity (EUI) for 3-star, 4-star and 5-star hotels are 61.95 kgce/m2, 73.18 kgce/m2 and 86.64 kgce/m2 respectively by converting all consumed energy into equivalent coal. In addition, some other factors were also reviewed such as occupancy rate and hotel's class. Some suggestions are put forward to improve energy performance of hotel buildings.
