The energy-saving standards in Japan will soon he revised. To achieve wide-scale energy savings, building owners are obligated to show their efforts toward energy conservation, building designers are oligated to design buildings efficiently, and administrative bodies are obligated to examine the energy performance of buildings. Although BEST ("the program") is a building energy simulation program that was developed in 2005 in Japan for demonstrating performance compliance with the Energy Conservation Eaw, it can also he used in the building design and operation phase for conducting whole-building life-cycle assessment. Since 2009, when the program was first used as a simulation software that corresponds to Japan's Energy Conservation Eaw, it has been downloaded more than 10,000 times. Between 2013 and now, the program has been further developed as a simulation software specifically for the revised Energy Conservation Eaw. In this paper, we will describe its features as a general-purpose building simulation program. In the program, building energy performance can he analysed based on factors that include thermal insulation, building envelope, air conditioning, ventilation, lighting, hot water, elevator, etc. It is also possible to perform renewable energy-related analysis that take into account solar power generation, storage battery, solar hot water system, and cogeneration system. The program can generate results that include energy consumption, weak demand, and annual cooling/heating load. In general, since there is a wide range of input parameters, energy simulation programs can only he proficiently operated by skilled professionals. For the purpose of simplifying energy efficiency planning by using the program, a graphical user interface (GUI) was developed to make the software easier-to-use and to minimise input mistakes. Users can easily understand and learn to use the program through visual representation of building information inputs and graphical icons for complicated equipment. Simulation outputs include comparison between a standard building and a proposed building or between various design alternatives, list of input values, and various detailed analysis results. This simulation program is the first software developed in Japan that not only can accommodate local design codes, hut also incorporates energy-efficient design strategies, technologies or building systems that are widely adopted in Japan hut uncommon in other countries.
INTRODUCTION In February 2016, thejapanese energy saving law was drastically revised for the first time in 15 years, due to the steady increase in energy consumption in japan since 1990. [...]
