External Shading
The deep overhang projection over the glass wall on the southeast facade blocks high-angled sun, but allows good views towards the landscape area. The trellises provide additional shading.

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.
Northwest Shading
Vertical shading fins on the northwest facade shade the glass walls when the sun is at low and shallow angles in the early morning and evening, cutting out glare and heat.
