JapanJapan’s NZEB goals are part of the broader framework of policy instruments to reduce carbon dioxide emissions in the country.
Tangible NZEB milestones have been set to be achieved till 2050. All new buildings will be zero energy buildings by 2020 and all existing buildings will be zero energy buildings by 2050. Thrust of the policy efforts are transforming residential sectors. Net-zero-energy houses will be available in the market by 2020.
JapanEnergy Efficiency Building Codes
Japan has set voluntary building standards for both residential and commercial buildings. These standards are being strengthened repeatedly to achieve the stated goals by 2030.
Comprehensive Assessment System for Building Environmental Efficiency (CASBEE)
CASBEE, a green building rating system, evaluates environmental performance of buildings beyond site level. CASBEE has been made mandatory by around 24 local governments in Japan.

Top Runner Program
Weighted average energy efficiency of products sold in the target year must comply with the standards. Different standards are formed for each product, varying by the technology used and also by the potential to improve efficiency of the technology by the target year. As of 2009, 21 end use products are under the scope of this program.

Japan has launched series of loans, grants and tax incentives program to give impetus to energy efficiency in buildings.
Low Carbon Cities Promotion Act
Tax breaks are offered for “low carbon buildings”, essentially buildings exceeding minimum energy performance standards or with features that increase

Eco-point Housing Program
Points are provided to home owners for energy efficient measures in new or renovated buildings which can be later exchanged for purchasing energy efficient appliances or products.
Zero‐Energy Housing Grant Program
Selected zero energy residential projects are provided grants equivalent to approximately half of the subsidy that they are otherwise eligible for. Both new and renovation projects are considered for grants.
Flat 35 loan by Japan Housing Finance Agency
Loans on low interest rates are provided to houses with energy efficient measures.
