AIRSIDE advocates a sustainable green lifestyle

Situated next to the Kai Tak MTR Station, this mixed-use commercial development comprises a 32-storey Grade A office tower; a multi-storey retail podium; a landscaped elevated walkway; and a public transport interchange.

AIRSIDE is the first commercial development in Hong Kong to adopt the Kai Tak District Cooling System (DCS), and has installed the largest photovoltaic (PV) farm among Hong Kong’s commercial buildings.

To fulfil the tight construction programme, a hybrid ‘semi top-down’ construction method with high-strength steel stanchions and post-tensioned concrete was implemented to enable simultaneous construction of the superstructure and basement box structure. The project team also reduced the structural elements’ section size and the use of steel reinforcement. Eventually, the semi top-down construction was shortened by seven months compared to the traditional bottom-up construction, with a significant decrease in the use of materials and supports, reducing carbon dioxide emission by 6,800 tons.

Other sustainable features include the rainwater recycling system that saves the amount of irrigation water needed by more than 70 per cent, and the use of eco-friendly materials. The retail podium features an interior ‘fabric’ that is upcycled from over 100,900 polyethylene terephthalate (PET) bottles.

The project aims to cultivate green practices in waste reduction and recycling. It is the first in town to adopt an automatic refuse collection system with smart waste management functions to collect and sort four common waste streams (general refuse, recyclable paper, plastic and metal) from office and retail operations. It has an automatic smart weighting function and tenant identification for occupants to relay actual waste generation, tying in with the soon-to-be-launched Municipal Solid Waste Charging by the Hong Kong Government.

Artificial intelligence has been used extensively to monitor and optimise operations. The digital twin system continuously visualises and measures building performance to identify energy inefficiencies and provide recommendations to improve energy conservation.
