AIRSIDE, Hong Kong

Top-rated green and smart grade-A office & retail development at Kai Tak by Nan Fung Group

Kai Tak area in Kowloon East is Hong Kong’s next-generation CBD, with many developments here taking a smart, green and efficient approach through adopting innovative and sustainable solutions.

Nan Fung acquired the land parcel called NKIL 6556 and developed it into the AIRSIDE. Nan Fung strives to create more value for the 1.7ha site with a people-oriented environment and social inclusive community. In collaboration with our client, Arup’s planning, structure, façade, traffic, sustainability, fire engineering, ICT and building services teams jointly engineered a 178,000m² landmark Grade-A office and retail development, which is also a top-rated green and smart commercial development and neighbourhood hub in this new CBD.

Project Summary


1st BEAM Plus Neighbourhood Final Platinum-rated commercial development

1stAutomatic Underground Bicycle Parking System in Hong Kong

15,000ft²⁺PV farm in commercial development

‘CO₆ Metrics’ Framework

With United Nations Sustainable Development Goals as the design blueprint for this development, the team has built a new ‘CO₆ Metrics’ framework – covering ‘Community Hub Creation’ (SDG 11), ‘Comfortable & Healthy Environment’ (SDG 3), ‘Carbon dioxide (CO₂) Reduction’ (SDG 7 and 13), ‘Conspicuous Performance & Consumption’ (SDG 12) and ‘Cost Effective Smart Technology’ (SDG 9).

Our holistic approach turned the project into Hong Kong’s first private development to achieve the top Platinum rating under BEAM Plus Neighbourhood scheme. Moreover, it is targeting Platinum ratings in BEAM Plus New Buildings, LEED and WELL, as well as 3-star rating under China’s CGBL scheme. Our experience in planning approvals in the territory will enable us to facilitate the local authority approval of the master layout plan and realise the green vision.

A neighbourhood open for all

Surrounded by lush greenery covering 33% of the site area, including vertical green walls of over 1,000m², this project will significantly improve the neighbourhood by enhancing people’s wellbeing. Moreover, there will be a 20m setback along Kai Tak River to create a wider promenade. Together with an open plaza for activities and events, this place is indeed an inviting space for everyone to enjoy.

Microclimate studies were also conducted to shape the building form with an urban window to enhance outdoor comfort and local wind environment. Water features will be crafted to reduce the heat island effect in compact urban environment.

Linking the heart of CBD

There will be abundant choices within the neighbourhood’s low-carbon mobility network – bus, MTR, the proposed Environmentally Friendly Linkage System (EFLS), bike, electric car or on foot. In particular, the development will provide premium end-of-trip facilities for cyclists, including an automatic underground bicycle parking system, the first-of-its-kind in Hong Kong.

As the focal point of the Kai Tak area Arup will manage the design and planning of the transport facilities including ingress/egress, internal traffic circulation, parking, loading/unloading and pedestrian connectivity to the public transports and elevated walkways. Utilising our teams’ experience, Arup will enhance the transport planning and traffic engineering designs to optimise the intrinsic and real value of the development.


Setting new environmental benchmark

This development is set to achieve exemplar environmental performance through passive design, energy-efficient infrastructure and renewable energy system. A high-performance façade system with solar and glare responsive design can reduce thermal transfer and air conditioning use. The building will also be connected to the Kai Tak District Cooling System (also realised by Arup), and an onsite photovoltaic system covering over 15,000ft² to produce 270MWh of electricity each year.

We will also adopt an automatic refuse collection system to sort waste at source and facilitate the implementation of mandatory waste charging scheme. Other environmental initiatives include rainwater recycling, extensive landscape and man-made wetland. Arup-engineered Air Induction Unit (AIU) will also be used on G/F to provide cooling effect for occupants’ comfort.

Daily operations – smart and green

A number of innovative approaches will be adopted for enhancing the green experience of tenants and occupants. These include sub-metering, IoT-based smart urban farm, waste volume monitoring and parking app for carpark navigation and slot booking.

Apart from energy efficiency, real-time analysis and preventive maintenance enabled through artificial intelligence and machine learning, it will also help building a smart community platform to bring a unique retail experience with a personal touch for both tenants and mall-goers.
