Japanese construction company Takenaka Corp. announced on July 23 that it constructed a zero-energy building at as low cost as general buildings. Use of conventional technologies lowered the cost. The company intends to promote the building as an example of wide-use ZEB.

The office building has been certified as Nearly ZEB by BELS, reducing energy consumption by 75%. As it is usually considered that ZEBs are expensive to build, Takenaka can provide Wide-use ZEB at the same cost with a building of the same size. Insulation panels on façade, automatic lightings, rainwater-using air-conditioning and solar power generation contribute to high energy efficiency. (2018/07/24)
