Effectiveness of energy conservation measures in residential sector of Japanese cities

Energy consumption by residential sector of 20 Japanese cities was modeled at the city-scale. In the model, households were classified into 228 categories based on the family and building type. We evaluated the effectiveness of energy conservation measures, such as improving energy efficiency of home appliances, improving heat insulation of buildings, changing preset temperature, and all family members watching TV together. In addition, we also discussed differences in energy saving effects between cities.

INTERNATIONAL COMPARISON OF RESIDENTIAL ENERGY CONSUMPTION

In this study, I surveyed household energy consumption and related indicators in various western andAsian countries. In the western countries, household energy consumption shows a trend towardsaturation, but in the Asian countries it is likely that household energy consumption will continue to rise.In rural areas of Asia, especially because the energy infrastructure has not yet been completed, theremay also be, on the positive side, opportunities to encourage acquisition of innovative energy systems.
