A survey on energy consumption status and characteristics of hotel buildings in Guangzhou

Abstract

Existing hotel buildings are normally of high energy consumption and low energy performance in China. The implementation of energy efficient measures is an approach to improve this situation; but it is essential to have a thorough understanding of their energy consumption patterns beforehand. In this paper, a survey on energy consumption status and characteristics of 14 hotel buildings in Guangzhou was conducted. Through a comprehensive analysis of the annual, monthly and subentry energy consumption of different buildings, combined with an on-site inspection, it has been found that existing hotel buildings in Guangzhou have very good energy-saving potentials, especially in terms of the glazing of building envelope, air conditioning systems, hot water systems, and lighting systems.
