Energy Efficiency and Decarbonization of Buildings

ZEB market players

In the 2030 target for Japanese government to achieve carbon neutrality by 2050, 50% of reduction in GHG emissions is required for energy consumption in buildings and other non-residential constructions that belong to "Other Divisions". Therefore, expansion of ZEBs (Net Zero Energy Buildings) that contribute to zero emissions is imperative. The government aims to secure the level of ZEB-standard energy saving performance for average numbers of new buildings by 2030 and those for building stocks by 2050, forcing the designs for non-residential buildings to meet ZEB benchmarks hereafter. This report covers the status on the ZEB market in Japan from the statistics and from the efforts by the businesses that deal in ZEBs, and the future perspectives and challenges for 2030.
