BSB COMPANY PROFILE
Established in 2009, BROAD SUSTAINABLE BUILDING CO., LTD (BSB) is a wholly-owned subsidiary ofBROAD
Group and a specialist manufacturer of factory-made sustainable buildings as well. Upuntil 2015, a total investment of more
than 666 million USD has been invested for research anddevelopment, and more than 30 pilot and commercial projects have
been completed. BSBCentral Factory is located in Xiangyin, Hunan, with 230,000m2 workshops and 1,800 staff.
Technology: “Factory-made” methodology is the core value, which means factory-prefabricationby
90% from the structure, exterior wall & window to interior decoration and MEP. It has disruptedthe conventional
construction. Buildings are designed per the local structure and fire protectionstandards so that local approvals can be
obtained. For instance, the tallest building in the world,a 202 story building which was designed by BSB got the approval
from Chinese government onApril 1, 2014.
Quality: All component designs are finalized only after experimental verifications in workshops.
Allcomponents are delivered only after the quality control process inspection through production,and installation can be
progressed after quality control inspection approval in every process, sothat a zero-defect acceptance on top-sealing is
Cost: As factory-made technology is used, the efficiency of production, installation, logistics
hasbecome 6-10 times higher and material waste is next to zero, the total cost is 20-40% lower thanthat of conventional
BSB’s core value sticks to “7 sustainable principles”:
1. 90% factory-made (construction waste less than 1%)
2. 5 times more energy efficient
3. PM2.5 filtration by 99%
4. Withstand a 9.0 magnitude earthquake
5. land saving (a focus only on high-rises)
6. material saving ( all steel structure, recyclable)
7. durable (e.g. stainless steel pipes for water supply, air-conditioning and fire protection).
BSB’s primary value is energy saving: 15-30 cm thermal insulation and 3-4 paned glass windows are
applied respectively per local climate zones. Fresh air heat recovery machines and CHP system are equipped with all BSB
buildings, which have enhanced energy efficiency 80% higher than that of conventional non-insulated buildings. If all
buildings in the world could adopt BSB technology, 30%+ global energy would be saved. Never has a technology in human
history borne so profound social impact.
Position in the Industry
In the global construction industry, BSB is the only enterprise which uses “factory-made”
methodology to build super high rises, and also is the only one which has reached 90%factory-made level. Nowadays, there
are many companies that produce precast concrete buildings and several companies that build steel structures at home and
abroad. It features some prefabricated structures in factories, most of the work is done onsite. Generally prefabrication
accounts for 20-40%.
BSB proprietary technology was invented by BROAD Group with more than 80 patents. From 2011 to
2015, time lapse videos of “15-story hotel built in one week”, “30-story hotel built in 15 days”, and “57-story
building built in 19 days” have received successively more than 15 million viewers on YouTube, which has rocked whole
world again and again. BSB was honored with “the Innovation Award in 2013” from CTBUH (Council on Tall Buildings and
Urban Habitat), became the first winner from the construction industry in China. Jury Statement reads: “Tall building
designers have used prefabrication techniques on discrete elements for years, but never before has an entire prefabricated
building system been developed to this degree. It is both a structural and mechanical engineering response to the demands
of a rapidly urbanizing world. Integrating a bolted assembly technique with triple glazing, automatic blinds and air
filtration systems. The BSB Method is a clear and innovative way of fundamentally rethinking tall building construction,
and holds great promises for the future.”
