The Trade and Industry Tower in Hong Kong, built by Dragages Hong Kong, is the embodiment of excellence as far as environmental standards are concerned. The project features numerous green innovations, including a photovoltaic power system, solar water heating, low environmental-impact materials, rainwater recovery, a fibre optics daylighting system, air-conditioning using the district cooling system and green walls and roof gardens that account for 30% of the surface of the building. Everything combines for this ultramodern structure, which houses offices for the government and several government departments, to qualify for double LEED® Platinum et BEAM® Platinum certification.
