China Resources Building green retrofit, Hong Kong

A landmark building renovation project for Hong Kong

When built in 1983, China Resources Building was the tallest in Hong Kong. At 25 years old, it has undergoing renovation in line with modern building sustainability targets. Arup has been appointed as the green building and LEED® consultant for this ambitious regeneration project.

The building boasts a façade that optimises daylight and energy consumption by using a glazing system that allows only 5% of solar energy to be transmitted indoors, naturally reducing interior temperature. The air-tightness of this façade also reduces the need for air conditioning.

With the implementation of the proposed energy saving strategies, including the use of an innovative lighting system and upgrade of the air handling units, an energy saving of 1.65GWh will be achieved every year – the equivalent to the energy used by 5,200 fluorescent tubes. The building's CO2 emissions will also be reduced by 1,370 tonnes – the equivalent CO2 absorbed by 200,000 pine trees in one year.
