Celebrating New Milestones at the Energy Efficiency Expo

The Environmental & Energy Efficiency Calculation Center, led by CEO Keisuke Onoshi and based in Toshima, Tokyo, has reported a remarkable achievement—experiencing a 1.4-fold increase in its building energy efficiency calculation orders over the previous year, totaling 1,400 buildings annually. This significant growth comes as the company prepares to showcase its offerings at the 3rd Decarbonization Expo for Buildings at the Japan Build Tokyo event, scheduled from December 10 to 12, 2025, at Tokyo Big Sight.

The Importance of Energy Efficiency

With the enforcement of the revised Energy Saving Law in April 2025, all newly constructed buildings will be required to comply with national energy-saving standards. This legal shift demands a rapid increase in the number of buildings requiring energy efficiency calculations, as sustainability becomes a priority in the architectural industry. Furthermore, the push toward decarbonization has prompted many existing buildings to seek environmental performance certifications such as BELS, ZEB/ZEH, and CASBEE.

What We Offer

The Environmental & Energy Efficiency Calculation Center actively supports a wide range of buildings—residential, commercial, healthcare, and educational facilities—providing essential energy efficiency calculations and facilitating the acquisition of environmental performance certifications. Our client portfolio includes architectural firms, developers, general contractors, real estate funds, and J-REITs, amassing a total of 4,000 completed projects and continuing to expand our reach.

At our booth during the expo, visitors can engage with our seasoned specialists, who offer guidance on energy efficiency calculations, compliance assessments, environmental performance certifications, and more. We will also introduce our innovative support service utilizing AI technologies aimed at enhancing productivity in architectural and design tasks.
