Wind Catchers
Each wind catcher harnesses the wind and draws fresh air from the roof. Behind an internal divider, stale air exits through the opposite half of the stack. The fresh air intake is regulated by motorized dampers.
Wind over the roof is drawn into the centre of the building.
Improves the natural ventilation potential for areas furthest away from windows.

What is ZCB?
ZCB is the first Zero Carbon Building in Hong Kong with energy plus status and net zero carbon emissions on an annual basis. It was developed by the Construction Industry Council to showcase state-of-the-art low carbon building design and technologies to the industry locally and internationally, and to raise community awareness of low carbon living in Hong Kong.
In recent years, environmental problems like global warming and resource scarcity have become important issues and energy conservation plays an important role in alleviating these problems. Through integrated passive building design and energy efficient active systems, ZCB minimizes energy consumption and demonstrates the balance between nature and the built environment.
ZCB also generates on-site renewable energy from photovoltaic panels and a tri-generation system using biofuel made of waste cooking oil to meet its energy consumption needs.. Beyond this, ZCB exports surplus energy to offset the embodied carbon from its construction process and major structural materials. ZCB is the blueprint for promoting the adoption of low carbon design strategies and technologies for future buildings.
Sensors
Sensors collect relevant environmental data on internal temperature, CO2, wind movement and humidity for the Building Management System that controls the dampers. Manual control mode is also available.
