Study on Energy Use Characteristics of Hotel Buildings in Shanghai

摘要

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 hotels were mostly built after 1990s with guest rooms,taking up 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 which also affect the energy use in hotel buildings,such as hotel occupancy and hotel's class have been reviewed.This study helps to understand the current energy performance of hotel buildings for further energy retrofit.
