ESTIMATING CONSUMER SECTOR ENERGY CONSUMPTION THROUGH TOTAL FLOOR SPACE CORRECTION OF BUILDING POINT DATA

Abstract

 To promote global warming countermeasures in Japan, it is necessary to design an evaluation technique for the energy policy on block unit scale. Building point data has the potential to fulfill this requirement. However, building point data must be used correctly because it tends to exaggerate the estimate of the total floor area. This study aims to estimate the energy consumption of the consumer sector using the bottom-up approach through total floor space correction and vacancy rates consideration on building point data. The results of the study, estimates of the energy consumption of the prefectures, and ordinance-designated cities confirmed that a high reproducibility compared with the statistics can be obtained. In addition, we consider the applicability of this technique in the municipalities and propose it as supporting material for the action plans for global warming countermeasures of local governments.
