Abstract
We carried out measurement about the consumption and the usage of hot and cold water of the guest rooms in a city hotel. The purpose of this study is to develop the calculation method for hot and cold water consumption in the guest rooms of city hotel by the Monte Carlo simulation technique based on the analysis of hot and cold water usage. In this paper, as part 2, we compared the two kinds of calculation results; the each using model and the room unit model and considered about the effectiveness of calculation by the room unit model.
