Abstract
The hotel industry in China has experienced rapid growth in the past ten years and made a considerable contribution to the global tourism economy. This paper focuses on the energy performance of hotel buildings in Lijiang, China. Hotel characteristics, daily operational data, and energy use data were collected by carrying out a survey of 24 hotels. The average annual energy use intensity (EUI) of four-, three-, two-, and one-star rated hotels was 180.8 kWh/m2, 113.3 kWh/m2, 74.2 kWh/m2, and 70.2 kWh/m2, respectively. Electricity, as the dominant energy source, accounted for 81% of total energy consumption and was used in the operation of air conditioning, lighting, heating, etc. Pearson correlations between EUI showed that hotel star rating, number of guest rooms, room revenue, and number of workers gave a reasonably strong correlation. A regression-based benchmarking model was established to predict EUI, and a standardization process of EUI was illustrated by statistical analysis.
Highlights
In recent years, tourism has become one of the fastest growing economic industries in the world.Tourism in China has made a considerable contribution to the global tourism economy, and China has shown, by far, the fastest growth with regard to expenditures on international tourism [1]
This paper aims to analyze hotel energy consumption in Lijiang based on a regression-based model
The highest energy use intensity (EUI) was found in four-star hotels, with an average EUI of 180.8 kWh/m2 ; the second highest was found in three-star hotels, with an average EUI of 113.3 kWh/m2 ; the third highest in two-star hotels, with an average EUI of 74.2 kWh/m2 ; and the lowest was found in one-star hotels, with an average EUI of 70.2 kWh/m2
Summary
Tourism has become one of the fastest growing economic industries in the world. Tourism in China has made a considerable contribution to the global tourism economy, and China has shown, by far, the fastest growth with regard to expenditures on international tourism [1]. The accommodation sector plays an indispensable role in the tourism industry and has a significant global environmental impact [3]. The hotel industry in China has experienced rapid growth in the past ten years, and this trend is expected to continue in the future. The number of star-rating hotels in China increased from 7358 in 2001 to 11,779 in 2010, and the total revenue raised by 330% from USD $7.3 billion to USD
