Beijing 2019 Horticultural Expo Vanke Kaleidoscope Project: Prefabrication Technology Empowers Green Buildings and Sets an Industry Benchmark

As the core highlight project of the 2019 Beijing International Horticultural Expo (hereinafter referred to as the "Expo"), Vanke Kaleidoscope has become a highly regarded green building model during the exhibition period with its unique design concept and advanced building technology. This project is not only the building with the largest indoor planting area in the World Horticultural Exposition, but also showcases the dual value of green building and efficient construction through the innovative application of prefabricated construction technology, breaking the limitations of traditional building models.

It is reported that the main body of the Vanke Kaleidoscope project adopts a steel structure design, with a total construction area of 11000 square meters. The core uses steel framed lightweight roof panels and daughter wall panels as the main building materials, achieving a perfect integration of building functions and environmental protection concepts. It is worth noting that the roof panels used in this project have outstanding load-bearing capacity and can withstand a planting soil weight of 1.2 tons per square meter, successfully replacing traditional concrete structures. This not only reduces the weight of the building, but also provides a solid guarantee for roof planting, which is in line with the core theme of the World Horticultural Exposition "Green Life and Beautiful Home".

Compared to traditional construction techniques, the prefabricated technology used in the roof cover and parapet construction of the Vanke Kaleidoscope project demonstrates significant comprehensive advantages. Through multidimensional comparison, its high efficiency, economy, and convenience are particularly prominent. In terms of cost control, prefabricated technology significantly reduces the cost of construction measures. Under the traditional construction mode, the cost of measures is 300000 yuan, while prefabricated construction only requires 100000 yuan, resulting in a cost savings of 67% and effectively optimizing economic benefits; In terms of construction efficiency, prefabricated construction has significantly shortened the construction period compared to traditional techniques. The roof cover and parapet construction, which required 25 days for traditional construction, can be completed in just 10 days using prefabricated technology, increasing construction efficiency by 150% and providing strong guarantees for the overall on-time delivery of the project; In terms of construction adaptability, prefabricated technology completely breaks the seasonal limitations. Traditional construction modes are unable to carry out operations due to the low temperature in winter, while prefabricated construction can smoothly achieve winter construction, effectively avoiding the constraints of seasonal factors on construction progress and demonstrating the flexibility and practicality of the technology.

As the first core venue built by enterprises at previous A1 type expos in China, the Vanke Kaleidoscope project not only carries functions such as plant display and science education, but also becomes a practical benchmark for prefabricated building technology. The application of lightweight steel framed roof panels fully utilizes the advantages of lightweight insulation, fire resistance, durability, environmental protection and energy conservation of this material, which not only conforms to the development trend of green buildings, but also provides valuable experience for the construction of large public buildings.

The successful implementation of the Vanke Kaleidoscope project not only showcases the development achievements of China's green building and prefabricated construction technology to the world, but also provides a vivid example for the transformation and upgrading of the construction industry, promoting the industry to continuously move towards efficiency, environmental protection, and low-carbon direction.
