Japan METI of Japan Compiles Measures for Homes and Buildings to Achieve Carbon Neutrality by 2050

Publication of “energy conservation measures in homes and buildings for a decarbonized society”

On August 23, 2021, the Ministry of Economy, Trade, and Industry (METI) published a report of “energy conservation measures in housing and buildings for a decarbonized society”.

 

The main points of the report

  1. The future vision of housings and buildings to be achieved in 2050 and 2030
    Desirable scenario in 2050
    Energy-saving performance at the level of ZEH and ZEB standards will be secured in the stock average, and the introduction of renewable energy such as photovoltaic power generation equipment will become common in houses and buildings where it is reasonable.
     Desirable scenario in 2030
    Newly constructed houses and buildings should have energy-saving performance at the level of ZEH and ZEB standards, and 60% of new detached houses should be equipped with photovoltaic power generation systems.
  2.  

  3. How to proceed with efforts to achieve carbon neutrality in 2050
    1. Household and business sectors (strengthening of energy conservation measures in homes and buildings)
      Mandatory compliance with energy conservation standards, including residential buildings, in FY2025
      By 2030 at the latest, when the rate of compliance with the guidance standards exceeds 80%, raise the mandatory energy-saving standards to the energy-saving performance at the level of ZEH and ZEB standards
    2. Energy conversion sector (expansion of introduction of renewable energy)
      Expand the use of renewable energy and unused energy according to local conditions, such as photovoltaic power generation, use of solar heat and geothermal heat, and use of biomass.
    3. Absorber measures (expansion of wood use)
      Further rationalization of building standards for wooden buildings, etc.
