The final energy consumption in Japan’s commercial sector has approximately tripled since the oil shocks, and it accounts for 20% of all of Japan’s final energy consumption. Meanwhile, in response to a tightening of the electricity supply-demand balance after the Great East Japan Earthquake and the instability of energy prices, the importance of energy conservation in the commercial sector has been recognized again.
A ZEB (Net Zero Energy Building) is a cutting-edge building that significantly reduces annual energy consumption by generating energy by means such as photovoltaic power generation, while significant energy conservation is realized through the utilization of sunshades and natural energy realized through careful building plans, high heat insulation performance, and high energy efficiency improvements. The realization and promotion of ZEBs are expected to fundamentally improve the energy supply-demand structure in the commercial sector.
In response to such situations, Japan’s Basic Energy Plan, approved by the Cabinet in April 2014, stipulates the policy goal of aiming to realize the ZEB concept both in newly-constructed public buildings by 2020 and in newly-constructed public and private buildings on average by 2030. In order to realize this policy goal, the Ministry of Economy, Trade and Industry (METI) released the Report on the ZEB Roadmap in December 2015, which summarized the definition of and evaluation methods for ZEBs, information on the feasibility of ZEBs, and measures to promote ZEBs toward the realization and promotion of ZEBs as specified in the Basic Energy Plan.
METI hereby releases a summary that illustrates the contents of the Report on the ZEB Roadmap in an easy-to-understand way. (In Japanese and English)
