Innovative Pre-Fabricated Engineered Bamboo Houses
New solutions for pre-fabricated engineered bamboo house design in China hopes to set the tone for future green construction.
The house design, which was managed by INBAR’s long-term partner the International Centre for Bamboo and Rattan (ICBR), uses lightweight steel frames as load-bearing components, with bamboo-based panels as building enclosures, such as walls and roofs. The walls and roofs of houses have a sandwiched structure, using laminated bamboo fiber bundle and wood veneer composite material for exterior surface panels, and bamboo OSB for interior surface panels.
The middle layer between the exterior and interior panels is filled with 10mm of rock wool for sound and heat insulation. Due to its low density, good durability and dimensional stability, the laminated bamboo fiber bundle and wood veneer composite material is a good option for exterior surface panels compared to other bamboo-based panels. Different types of steel connections are used to connect lightweight steel frames with walls, roofs, and floorings.
In addition, the house is equipped with a solar power supply system and a movable wall hydraulic control system. The latter can help open the wall to form an overhanging balcony for greater access to natural sunlight and air.
ICBR has constructed two pre-fabricated engineered bamboo houses in Inner Mongolia and Fujian province respectively. The pictures show the demonstration house located in Yong’An, Fujian province (with approx. 68,000 ha bamboo forests).
The house is around 45m2 in area and it would take 5 workers install it within a period of 7 days. The average price is around 2000 RMB/m2 which is 80% of the price of an equivalent timber structure house. Due to its modular design, customers can assemble different modules based on individual requirements. It can also be flat-packed and fit into a standard ICC container for ease of transport.
With several national policies of China robustly promoting pre-fabricated houses (built using green materials) supported (and published) by the Ministry of Housing and Urban-Rural Development of the People’s Republic of China (MOHURD) and the State Forestry Administration of China (SFA) in recent two years, ICBR is scaling up its plans to build more demonstration houses in Guangzhou and Sichuan provinces to explore its market potential.
International Center of Bamboo and Rattan (ICBR) was approved by the State Commission Office of Public Sectors Reform, the Ministry of Science & Technology and the Ministry of Finance in 2000, as a non-profit research and development department attached to the State Forestry Bureau.
The purpose of its establishment is to directly support the International Network for Bamboo and Rattan (INBAR), which is the first inter-governmental organization based in China with its headquarter at Beijing primarily working for Bamboo & Rattan. As per the agreement with China as a Host Country of INBAR, ICBR completely supports and cooperates with INBAR to promote the innovation, sustainability and the international reach of Bamboo & Rattan and its role in Sustainable Development.
