The Shenzhen International Low Carbon City Low Carbon Exhibition Hall project is located in the International Low Carbon City Park in Longgang District, Shenzhen. Based on Shenzhen's climate and site conditions, this project makes full use of the building itself and surrounding renewable energy. While meeting the functional needs of the exhibition hall, it reduces energy consumption through optimized architectural design and combines carbon offsetting methods to achieve zero-carbon goals, building an energy and carbon dual-control demonstration system, and creating China's first integrated full-curtain wall assembly system "zero-carbon, zero-energy consumption" building. 。

 

The original site was a temporary prefabricated house, with existing auxiliary equipment rooms underground and two exhaust towers already in place; the west side is only 6m from the existing Building A of the Low Carbon City, and the south side is 10m from Building B. To save construction costs, the design chooses to retain the underground infrastructure and demolish the above-ground temporary buildings. To avoid damaging the underground structure, the design optimized the foundation scheme to ensure that the foundations on both sides stably support the weight of the exhibition hall within the limited space, while not affecting the safety of the underground building. The exhibition hall is tilted to the northeast, and the distance from Buildings A and B gradually increases with the height, minimizing the feeling of oppression caused by proximity, reducing spatial interference with neighboring buildings, and giving the exhibition hall a unique visual identity.

The design of the exhibition hall adheres to the concept of integrating form, space, and structure, using the needs of functional spaces to configure the structural system, generating the most concise and efficient spatial layout.

 

Given the limited space on the ground floor, in order to expand the exhibition area, the design adopts a strategy of a large-area cantilever on the second floor. The main structure uses an overall truss system, ensuring structural stability while creating a spacious column-free exhibition space. The building floor uses a V-shaped folded plate to increase the span, achieving the integration of structural rationality and visual characteristics, while accommodating equipment pipelines and maximizing the net height of the exhibition hall.

The exhibition hall is based on a steel structure system and a full-curtain wall assembly, with an assembly rate as high as 70.2%. This saved a lot of time for the tight construction schedule and provided strong technical support for achieving the zero-carbon goal, in line with the concepts of environmental protection and sustainable development.

 

The "Zero Carbon Box" achieves an integrated full-curtain wall assembly system "zero-carbon, zero-energy consumption" building through the coupled coordination of six systems: passive technology, active technology, renewable energy system, intelligent operation and maintenance system, integrated construction system, and green building materials system.

 

The entire building integrates 26 low-carbon technologies (including a full-roof solar energy system, high-performance insulation system, high-performance curtain wall system, high-efficiency heat recovery ventilation system, etc.), 3 cutting-edge technologies (temperature-controlled glass skylights, intelligent external shading roller blinds, intelligent point-wise exhaust) and China's first steel structure full-curtain wall assembly zero-carbon technology This provides exhibition space for advanced domestic low-carbon achievements, while the building itself, as a comprehensive embodiment of low-carbon technology, fully reflects the concept of sustainable building development.
