Review of future weather data for building simulations available in Japan and confirmation of its characteristics

Buildings use a large amount of energy, depending on the climate. To design buildings with high energy and thermal performance in future, it is necessary to weather data that reflect future climatic information. Some files for building simulations have been developed. However, these datasets are based different predictions, each file has creation process. Such methodological differences may lead predicting buildings. Understanding characteristics type its appropriate use. limited information available properly utilizing simulations. This study aims provide better utilization. After thoroughly reviewing existing methods, we propose framework understanding their creative We collected five types Japan compared characteristics. One dataset climate provided by National Institute Environmental Studies (NIES). confirmed degree variation element predicted cooling/heating demand using Japan.
