Abstract

This paper presents a study on energy performance of Thailand’s hotel buildings. Energy consumption data, hotel characteristic and hotel operation data were collected from 63 hotels through a technical survey. The annual Electricity Consumption Intensities (ECI) of the sampled hotels were then calculated and the hotel parameters affecting electricity consumption of the hotels were analyzed by Pearson correlation. Results indicated that most of the sampled hotels in Thailand consumed electricity, Liquefied Petroleum Gas (LPG) and diesel. Electricity is the main energy source, accounted for 69% to 94%. The electricity was mainly used in air conditioning (57%), followed by lighting (18%), escalators (9%), water heating (8%), and fans and pumps (8%). The average annual ECIs of hotel buildings in Thailand were 321.84 kWh/m2, 35,210.40 kWh/guest room and 2,292.36 kWh/room night. Pearson correlations showed that worker density had a positive correlation with monthly ECI in kWh/m2 at 99% confidential level whereas Occupancy Rates (OR) had a negative correlation with monthly ECI in kWh/room night at 95% confidential level. The predictive model determined based on a stepwise linear regression indicated that the optimization of some hotel operational factors such as number of room nights, number of workers, worker density and OR could lead to the significant decrease in electricity consumption of hotel building in Thailand. © 2018, Khon Kaen University,Research and Technology Transfer Affairs Division.
