Airside is located at the heart of former Kai Tak airport site, occupying approximately 1.7 hectares of land and a gross floor area of up to 177,000 m2.

At the core of the new CBD of Kai Tak Area, the vision of this project is to create a people-oriented environment, social inclusive community with exemplar environmental performance. Situated next to the Kai Tak MTR Station and Station Square, it will be the tallest development in the area in the center of connectivity surrounded by residential and commercial buildings, parks, sports and cultural activities. The project targets to thread sustainability into the daily life of surrounding resident and building occupants by incorporating various sustainable features covering community, wellness, energy, resources and technology.

Green Features

Site Aspects

  • Soft landscaping of 30% site area and heat dissipation materials to cease urban heat island effect
  • Building orientation and different building setback create a wind corridor to significantly enhance wind ventilation at neighborhood pedestrian level

Materials Aspects

  • Implement a comprehensive Waste Management Plan targeting for over 60% recovery of construction waste
  • Provide automatic refuse collection system (ARCS) for the building to centralize and effectively handle both general waste and recyclable waste in a hygienic and more environmentally-friendly way

Energy Use

  • Annual energy saving of over 23% as compared to BEAM Plus Baseline
  • Energy efficient lighting fixture and lighting control system for both retail and office area
  • Provide fresh air volume as demand by CO2 sensors driven control at both office and retail
  • Low-e coated glazing and external vertical shading fins reduce envelop solar heat gain resulting lower cooling energy
  • The largest PV farm in a commercial building in Hong Kong, with over 1,500 m2 at building’s roof area and canopy of podium roof garden to generate renewable energy.

Water Use

  • Above 60% potable water saving through the use of water efficient fitments
  • Use of low flow dual-flush flushing fitments decreases effluent discharge over 50%
  • Over 70% irrigation demand reduction by adopting adaptive species and rainwater recycling system

Indoor Environmental Quality

  • Fresh air is increased by 30% in normally occupied areas for both retail and office area
  • High performance air filtration devices e.g. MERV14, carbon filter and UV lamp to control indoor air quality to meet Hong Kong Environmental Protection Department (EPD)’s excellent class

Innovations and Additions

  • The first-in-place underground automatic bicycle parking system in Hong Kong with cycling supporting facilities encourages green transport and healthy living
  • Food waste decomposer to reduce daily food waste volume from F&B area and the treated food waste will be used as the fertilizer for building’s greenery area


Nan Fung’s endeavor for sustainable city development is ongoing and evident in its portfolio of residential, commercial and revitalization projects. In Airside, our vision is to create a people-oriented environment, social inclusive community with exemplar environmental performance and advanced sustainability features. Our team has developed the Sustainability Development Framework – CO6 Metrics for this project.  The CO6 Metrics includes Community Hub Creation, Comfortable & Healthy Environment, CO2 Reduction, Conspicuous Performance & Consumption and Cost Effective Smart Technology, which echo with the United Nations’ Sustainable Development Goals (UNSDG).

With this framework, sustainable features and practices are shaped to establish our project to be the benchmark in the new Central Business District 2 of Hong Kong. The project achieved the highest ratings across five major and globally recognized green building certifications, namely LEED v4 Core & Shell Platinum (pre-certified), BEAM Plus New Building Platinum (provisionally achieved), WELL v1.0 Core & Shell Platinum (Pre-certified), BEAM Plus Neighbourhood v1.0 Platinum (final certification achieved) and China Green Building Label 3-Star (final certification achieved).

To nurture luxury outdoor space in dense Hong Kong for community hub, the development cascades from office tower to retail podium to create lush rooftops, terraces and grounds for open-air space shaping for cultural, social and public engaging activities. Overlooking the Kai Tak River, future Kai Tak Sports Park and Victoria Harbour, visitors not only enjoy the waterfront view from podium roof, but interact at the publicly accessible, extensive with 1,700m2 greenery open spaces for activities, respite and foliage.

Considering the impact of prevailing wind and local microclimate at Kai Tak area, microclimate studies were performed, and an urban window between two towers was designed to significantly improve ventilation of the podium. With thermal comfort a high priority, sitting areas were also designed to use innovative cooling panels and air induction units will be installed. PV panels will also be installed to provide shading and, from initial studies, can also generate enough electricity to cover average consumption of 700 residential units in Hong Kong.

The building’s orientation also maximises sunlight, and through our glare studies and advanced computations, we optimized the profiles and sizes of the façade’s vertical shading fins to reduce solar heat gain but preserve our fabric-like façade design – a flashback to the Group’s founding business and its roots as a textile manufacturer.

To ensure a desirable and healthy environment, high performance air filtration devices, e.g. MERV14, carbon filter and UV lamp will be installed in building by minimizing both the outdoor and indoor air pollutants. Indoor air quality will be monitored by real-time air quality sensors. Both the air filtration devices and real-time air quality sensors contribute on achieving the WELL v1.0 certificate platinum grading.

The built-in Automatic Refuse Collection System encourages tenants to separate recyclable waste from general waste, which is weighted, transported and stored in a centralized and enclosed facility in a hygienic manner. It allows the development to be future-proof with the industry moving towards green leases and the potential soon-to-be-launched mandatory waste charging scheme in Hong Kong.

Adjacent to the public cycling path, Airside will have Hong Kong’s first automatic underground bicycle parking drum. It aims to create a cycling-friendly environment by embodying a new user friendly, simple and automated bicycle parking experience to further encourage green transport.

Passing on the development team’s 5D BIM model to the property manager, the embedded network of Internet-of-Things (IoT) devices and sensors and a sophisticated sub-metering network feeds real-time information to a digital platform which consolidates data sourced from disparate building systems and will use machine-learning processes to evaluate and forecast building performance to formulate building operation and maintenance saving strategies.
