A study on the estimation of energy consumption rate of accommodation buildings - Analysis based on survey data in 2009 fiscal year on the database of energy consumption for commercial buildings (DECC): Part 2

In this study we aimed to identify characteristics of energy consumption of accommodation building by drawing on 2009 fiscal year of DECC survey data. Conducting statistical analysis on the base-load and the fluctuation-load on a national scale derived from patterns of variation in the monthly energy consumption, we obtained estimation equations for energy consumption rate. To determine the base-load rate, we focused on differences between heat-generation equipments in the accommodation buildings and classified them into three categories: electrical, fuel-based, and electric-fuel hybrid. We then carried out the multiple regression analysis for each category. As a result, we obtained accurate estimation equations for the electrical and the fuel-based heat-generation equipments. And to determine the summer and the winter fluctuation-load rate, we were able to obtain accurate estimation equations using the multiple regression analysis.
