1. Holon Building officially unveiled, building 11 storeys in one day, creating a global sensation(Jun.)
    After 12 years, with the efforts of 1000+ people and more than RMB 8 billion invested, BROAD Sustainable Building Co., Ltd. successfully unveiled the stainless steel factory-made Holon Building, which heralds the ultimate way of living way for humanity. On June 5th, 2021, the first 11-storey residence "Garden A-1" was built in Changsha in 29 hours. The video taken on site was broadcast by CNN and other world-renowned media, and received hundred millions of hits in a few days, rave reviews came like snowflakes. Netizens from all over the world are eager to live in this spacious, bright, exquisite and beautiful building, which is warm in winter and cool in summer with high energy efficiency. With healthy indoor air, a 1000-year lifespan and 10 times less CO2 emissions, earthquake resistance and fire protection Holon Buildings enjoy permanent safety. Customers from dozen companies visited Garden A-1 to try it out. 16 purchase orders of Holon Buildings valued at RMB 2 + billion were signed , and mass production was started.

  2. China Standard of "Technical Standard of Stainless Steel Core Plate Building Structure "on Holon Buildings formally implemented(May)
    China Standard "Technical Standard of Stainless Steel Core Plate Building Structure "on Holon Buildings jointly compiled by 13 institutions including BROAD Sustainable Building Co. Ltd, Hunan University, Tsinghua University and Tongji University, was formally implemented on May 1st, 2021. It marks China's construction technology on the world's advanced level, leading the global construction industry onto a sustainable development road where reinforced concrete will be phased out.

  3. BROAD B-CORE slabs of road and bridge passed 2.45 million times of fatigue load tests under China's national standard, a global revolution for road and bridge construction is set to begin(May)
    2.45 million times of fatigue load tests of BROAD B-CORE slabs for roads and bridges have been completed in the laboratory of Changsha University of Science and Technology, a national bridge inspection institution with Class-A qualification. All indexes have reached or exceeded the national standard, marking the industrialization stage of BROAD's elevated expressway, river-crossing and sea-crossing bridge technology. With the unique advantages of "faster, safer, more durable and cheaper construction", BROAD elevated expressway will set off a global road and bridge revolution.

  4. The world's largest medical equipment manufacturer sees BROAD non-electric chillers as the only choice to achieve zero emissions(Aug.)
    Three factories of Medtronic all chose BROAD non-electric chillers. By recovering exhaust gas from generators and waste jacket water, cooling operation costs and carbon emissions were reduced drastically. In this way, carbon dioxide emissions are reduced by 13,000 tons per year, equivalent to planting 690,000 trees.

  5. Bordeaux garbage power plant becomes EU 'net zero emission' benchmark after adopting BROAD non-electric heat pump(May)
    Veolia is the only one of the Global 500 that focuses on environmental services. It built a new waste power plant in Bordeaux, France, using BROAD non-electric heat pumps to efficiently recover the waste heat of the plant. Centralized heating supply in the surrounding area greatly reduced the heating costs for local people. Carbon emissions were reduced by 16,000 tons annually, equivalent to planting 850,000 trees. The carbon reduction targets of this project have attracted great attention in the EU.

  6. World's largest unitary Cooling, Heating and Power system (CHP) was put into service in Hangzhou Airport, helping China achieve "carbon neutrality"(Feb.)
    The third-phase Hangzhou Xiaoshan International Airport is an important transportation hub of 2022 Asian Games. It adopts BROAD CHP system to ensure the power stability and realize free cooling and heating services. It saves 9.216 million kWh of electricity and reduces 17,500 tons of carbon emissions annually, which is equivalent to planting 960,000 trees.

  7. Non-electric chillers help the largest data center in South China with carbon neutrality(Dec.)
    In order to achieve the goal of carbon neutrality, Wusha Big Data Center in Foshan, Guangdong chose 7 BROAD 11.6MW mega-sized non-electric chillers to cool the data center. By recovering waste heat from power generation, the project is expected to reduce electricity consumption by 120 million Kwh and carbon emissions by 105,600 tons yearly, which is equivalent to planting 5.77 million trees.

  8. Invention of large heat-piped heat exchanger fresh air machine, 100% elimination of virus cross infection(Oct.)
    BROAD invented the world's first Fresh Air Machine which provides 100% fresh air, filters PM2.5 by 99.9% , and recovers 80% heat recovery. The small type uses plate heat exchanger which separates fresh air and exhaust air completely. The large type (10000 m3 / h air flow) uses a rotary heat exchanger, and there is a potential risk of the exhaust air entering the fresh air, although even if the exhaust virus enters the fresh air, it will be killed by hi-volt static electricity, and intercepted by the HEPA filter. BROAD's "paranoid perfectionist technical style" drove us to abandon the rotary wheel and successfully developed the "large heat piped heat exchanger Fresh Air Machine", which completely separates fresh air and exhaust air.

  9. BROAD was awarded the world's first 5A Certificate of Green Energy Station Construction and Maintenance Service Certification(Oct.)
    Based on the Technical Specifications of Green Energy Station Construction and Maintenance Service Certification and implementation rules,they came into effect on June 1st, 2021, and after the survey and review of ten millions of sqm users operated by the China's largest central air-conditioning energy management contract operator, BROAD Energy Service Co. Ltd., China Standard Conformity Assessment Co. Ltd. (Beijing) awarded BROAD the 5A-level certificate of "Green Energy Station Construction and Maintenance Service Certification". It becomes the first company in the world to have received such an honor.

  10. The 8th UN Secretary General Ban Ki-moon, Qiu Baoxing and other wise men highly respected on the world stage called for zero-carbon Era at " BROAD Holon Building Global Conference"(Jul.)
    On July 16th, the "BROAD Holon Building Global Conference" was held at BROAD Town. Hundreds of officials, scholars, architectural experts and clients from dozens of countries around the world attended the conference, placing high hopes on the environmental protection value of Holon Buildings and enhancement of human life quality. Ban Ki-moon delivered a long speech : "Since 2009, BROAD has made great progress in developing the innovative concept of Holon Buildings. I believe this concept will prevail in the future because it is in line with the development needs of the zero-carbon era... Now, China is leading the world with its sophisticated high-tech like the Holon Building of the Broad Group".
