Enhancing energy efficiency with ArmaFlex^® in China Zun

For a building of superlatives, outstanding equipment insulation is a prerequisite to safeguard energy efficiency. The 108-storey, 528-metre high Citic Tower in Beijing, popularly known as China Zun, is the tallest building in the Chinese capital and the ninth tallest in the world. A building of that size requires large amounts of energy for heating, ventilation and air-conditioning (HVAC). As energy efficiency was key to optimise the equipment design and construction, Armacell was commissioned to supply 7,000 cubic metres of ArmaFlex to insulate the chilled water pipes and air ducts of China Zun’s HVAC systems.

China Zun was set to be the benchmark for green building design. To optimise energy efficiency of HVAC and refrigeration systems, the equipment requires protection from condensation. As part of the selection process of the equipment insulation material of choice, project designers visited multiple manufacturers of thermal insulation materials and chose ArmaFlex for the insulation of chilled pipes and air ducts for China Zun. The combination of ArmaFlex's superior performance parameters and of Armacell's reliable supply chain and technical customer service led to the appointment as the designated insulation material supplier for HVAC systems in China Zun.

ArmaFlex is trusted to provide reliable, long-term condensation control, without any external water vapour barrier.

More about China Zun

China Zun references to the zun, an ancient Chinese wine vessel that inspired the building’s design. The eye-catching landmark on the skyline of Beijing is an inspiring architectural highlight. So far, China Zun has set eight world records and received 15 national accolades:

• Deepest building foundation
• Highest number of floors
• Highest and largest indoor sightseeing platform

China Zun is said to be the world’s first skyscraper of more than 500 meters in height capable of withstanding an earthquake of 8.0 in magnitude on the Richter scale. Such stability is based, in part, on China Zun’s concrete-filled, multi-cavity steel tubular column, with a cross-section area of over 64 square metres.
