Abstract:
Water resources consumption of hotels is very large. Based on the sample investigation of 11 hotels in Tianjin, the structure of water utilization and water balance test reports of 6 hotels were analyzed. The main factors affecting water con2 sumption in hotels were identified through the principal component analysis and correlation analysis. T he basal water use quotas of hotels with different levels were calculated using the statistical analysis methods, including simple average method, weighted 2 average method, secondary average method, and probabilistic evaluation method. According to the differences of water consump2 tion in different types of hotels, the accommodation coefficients for different types of hotels were introduced and obtained from scientific calculations. In order to guarantee the effective implementation of water quota management and achieve the satisfaction rate of 70% for each hotel, the basal water use quota was suggested as 500 L/( bed# d) for hotels in Tianjin, and the accommo2 dation coefficient was suggested between 0. 3 and 1. 6. Compared with the existing water use quotas, the suggested water use quota is rational and advanced.
