Abstract
The purpose of this paper is to evaluate the quantitative energy conservation effects of the new Japanese energy saving standard by using city-scale energy end-use simulation model developed by the authors. This standard evaluates the energy consumption of a residential building by adopting various kinds of energy saving technologies, such as heat pump water heater, cogeneration system, photovoltaic power generation system, and high-efficiency air conditioners. Therefore, many options are available to achieve this standard, and it is difficult to evaluate the city-scale energy saving effects by the standard. First, combinations of technologies that achieve the 2013 standard are examined. Next, our simulation model estimates the city-scale impact of the 2013 standard on residential energy consumption in Osaka Prefecture. The change of the electricity load curve by implementing the standard is also discussed.
