Abstract: In Japan, according to the building energy efficiency standards prescribed in the Law Concerning the Rational Use of Energy, building constructors should review their buildings’ energy performance and report the review results to administrative agencies before they start building. To achieve further energy savings in building equipment, the Japanese government revised the standard in April 2013. For the revised standard, the National Institute of Land and Infrastructure Management and the Building Research Institute have developed new methodologies for estimating annual heat loads in perimeter zones, as well as the primary energy consumption of air-conditioning systems, ventilation systems, lighting systems, hot water supply systems, and elevators, and a web-based online simulation tool. Here, we show how the web-based simulation tool is used in the standard and give details of the calculation methodologies.
