Built in 1983, China Resources Building is set to take a major facelift. Situated in the commercial district of Wanchai north, the main focus of the renovation is to transform this 26-year old office building into a 'green' edifice. According to Dr Raymond Yau of Ove Arup, LEED consultant for the project, China Resources Building will be the first LEED CS 2.0 certified and the first Gold rated CS project in Hong Kong.

      In terms of architectural design, the structural frame of the building will be reused so as to reduce construction waste and the demand of resources. The building facade will be replaced by double low-e glass to enhance air tightness. Facade will also be upgraded by using RGB LED lighting, which is less than 2.2W/sq m for each illuminated wall as required by ASHRAE 90.1-2004, to reduce light pollution. Lighting design is focused on the building top part and glare impact to the surrounding low buildings were minimized during design. To reduce urban heat island effect, the building roof will use solar reflective materials with plantation.

      To reduce odorous indoor air contaminants, which are irritating and harmful to occupants, measures such as increased ventilation rate above the ASHRAE Standard 62.1-2004 by 30%, and the use of low volatile organic compounds materials for renovated spaces, will be taken.

      For electrical and mechanical equipment, the design term will upgrade air handling unit (AHU) for the whole building, as well as install CO2 Demand Control Ventilation System and high efficient lighting equipment.

      After the completion of major facelift, the building is expected to provide a model for existing buildings transforming into green and sustainable development. Economically, it can reduce the building operating cost, increase property asset value, and most importantly, extend the building life cycle.

      'Initial preparation work has commenced', said Mr Winson Chow, Managing Director of China Resources Property Ltd, 'The entire renovation work will cost approximately HK$500 million and takes 3 years to complete by phases.'

      The architect of the project is Ronald Lu & Partners. LEED Consultant is Ove Arup & Partners Hong Kong.
