Cooling System
The cool supply air slowly rises through natural convection as it picks up heat from occupants. The warm, stale air rises towards the ceiling, where it is exhausted from the space. This vertical airflow pattern also makes it less likely that germs will spread and improves the indoor air quality.
Separates the desiccant dehumidification process from chilling to prevent over-cooling.
Underfloor displacement cooling makes use of natural convection for cool air circulation.
Radiant cooling is highly energy efficient.

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.
Summer Cooling
In very hot seasons, chilled beams (which require less pump and fan energy to operate) will provide radiant cooling. In the basement, the desiccant wheel handles the dehumidification process separately from chilling, instead of overcooling the supply air as in conventional air-conditioning systems.
