In the wake of the Great East Japan Earthquake, Japan has initiated a process to redefine its national energy strategy. Energy savings achievable through energy efficiency improvements will form a major component of this new strategy.

With 69% of Japan's electricity consumption, and 36% of its total final energy consumption, the buildings sector is a prime source of energy savings. This IEA-SBC workshop, organized in partnership with the Japanese Sustainable Building Consortium (JSBC), the Ministry of Land, Infrastructure, Transport and Tourism (MLIT) and the Ministry of Economy, Trade and Industry (METI) will be an important forum to define the new energy efficiency strategy that will achieve a low energy building stock in Japan.

Japanese and international buildings experts discussed buildings energy efficiency policies in the new Japanese energy context. In the first session, they presented a number of policy options for a transition to low energy buildings in Japan, and how to model the economic impact of such policies. A second session analysed the leading technologies to achieve low- or zero-energy buildings in the Japanese building stock.  You can follow the proceedings at the following site
