Trade and Industry Tower Kai Tak, Hong Kong

A demonstration project for energy efficiency and sustainability

The Trade and Industry Tower Kai Tak is the first government building in the Kai Tak Development Area (KTDA) which will eventually become Hong Kong’s second central business district. Keeping with the KTDA’s ‘Green City’ concept, the tower sets a new benchmark of energy efficiency for office buildings in Hong Kong.

With a GFA of around 54,000m², the 22-storey building provides office space for various government departments and a community hall. Arup provided total engineering services to deliver this highly sustainable building, including structural, civil, mechanical, electrical and façade engineering, geotechnics, fire, landscape and lighting design, transport consulting and building sustainability.

The building adopts a number of cutting-edge renewable energy technologies such as solar hot water system, solar chimney, photovoltaic system and daylight sun-tubes.


Project Summary

26% less energy consumption is exptected

30%less potable water than normal office building

A wide range of passive and active green features have also been integrated to minimise impact on the environment and enhance occupant comfort. These include energy efficient lighting and equipment, ventilation demand control for air-conditioning, water saving measures, rainwater recycling for landscape irrigation and automatic refuse collection system.

The air-conditioning of the building is provided by the District Cooling System which is also one of Arup’s great achievements in Kai Tak.

As a result, the tower is expected to use 26% less energy and 30% less potable water than normal office buildings.

The building has been awarded Platinum certification for LEED and BEAM Plus (Provisional Assessment), and Grand Award at the Green Building Award 2014.
