Other Features

Water Use Management

There are 3 eco-toilets in this development, all equipped with low-flow sanitaryware and grey water recycling systems. One of the toilets has black water recycling treatment and waterless urinals.

Storm water harvesting is also in place. In addition, an artificial wetland with subsurface flow is integrated as one of the key landscape features to treat grey water / stormwater using the roots of the plants.

Native or adapted plants together with water-efficient irrigation systems have been used to reduce water consumption for irrigation of the landscaped area. All features aim to reduce fresh water use.

Low Carbon Materials & Construction

Wherever possible, materials that consume less energy or emit less carbon in the processes of extraction, manufacturing and transporting were used, for example:

Construction processes that consume less energy or emit less carbon were adopted. Balanced cut and fill construction was used for the excavation works for the basement and the filling of the urban native woodland. A lean construction approach with an emphasis on resource conservation (e.g. use of fair-faced concrete, unpainted metal works) was also adopted. The gabion wall construction made use of construction debris salvaged from demolition.

Eco-Workplace & Eco-Home

Two thematic showcases, eco-workplace and eco-home, are set up in the ZCB to not only promote further innovations in sustainable design and construction, but also to serve as a catalyst for behavioural change.

The eco-workplace is to showcase the green design and operation of the office, while the eco-home simulates a typical apartment with low carbon design and system installations.

Smart Controls/Building Management System

The building can constantly monitor itself through more than 2800 sensing points. The active system, as well as other building systems can be evaluated and optimized for their environmental performance.

Micro Climate Monitoring Stations

Four microclimate monitoring stations are placed on or around the building to evaluate how the building interacts with its surroundings. These stations are linked to the building management system and the Hong Kong Observatory.
