Achieving Carbon Neutrality through ZEB


We have set a target for ZEB to account for more than 50% of the design work we perform in FY 2025
The energy map for ZEB in the office building is used to achieve high efficiency and reduce utility costs for the entire building.
- Energy creation (Solar Power Generation)
- Energy storage (Storage Battery, Ice thermal storage)
- Energy conservation (LED lightning, High efficiency air-conditioning, Human detecting sensor, Low-E double glazed glass, Schedule control)
What is "ZEB"?
It stands for "Net Zero Energy Building" (ZEB) .It is a type of building that designed to achive a confortable environment while reducing the annual primary energy balance consumption in the building to zero.
