Design concept
Design concept：
“Power” is intangible and cannot be concretely expressed, so the design strategy of the State Grid Pavilion has given up the direct or metaphorical morphological characteristic, and instead pursues a spatial sense of presence.
Architectural design
Architectural design：
Seen from the site relation, the building curls up in one corner of the enterprise pavilions zone in a low key, which poses difficulties for the design. To respond to it with a positive site strategy, the architect adjusted the architectural axis based on the layout of the pavilion by two adjacent pavilions, thus to tally with the main arrival direction of visitors; there is a large-area aerial design of about 6m at the bottom, and the first layer of the building only occupies the northeast and southwest corners of the base, thus creating a huge passageway from main passages in the park to the urban road intersections, attracting pedestrians to flow in and strengthening the openness of the site.
An “energy box” is used at the entry to try to create an open and pleasant atmosphere through aerial and lifting design.

Structural design
Structural design：
• Adoption of a crossover column grid for the main structure, creating a spatial structure together with the roof structure of the building;
• Use of orthogonal-diagonal lattice quadrilateral spatial frame structure to realize the architect’s conception of the exterior façade;
• Use of the surface oblique grid of the building both as a decorative structural member and a bearing structure;
• Creation of a spatial stress system by the crossover column grid and the roof structure of the building; no use of vertical corner columns in four corners, achieving a smoother crossover grid splicing for the exterior façade;
• No use of the floor horizontal members used for conventional buildings on the main façade, embodying a relatively high integrity; presentation of the entire staircase/elevator room as a huge latticed column; adoption of plane or spatial for the floor beam;
• Profiled steel sheet and concrete combined floor (roof) + combined beam structure planned to be adopted for the slab and roof.

Green building
Green building：
To ensure the comfort level of people in the outdoor waiting zone, its design has adopted quadruple measures:
• Use of the aerial space of the “magic box” and the building to create its own shading zone with a total area of 1,100m2;
• Design of visitors’ queuing passageway direction into the summer prevailing wind direction, thus to avoid direct sunlight and provide cool breeze for people in the waiting zone;
• Adoption of solar thermal collectors to heat the air in the patio, and utilization of thermal pressure to create a natural draft effect and keep a steady breeze in the waiting zone;
• Cooling by the fine water mist cooling system for local cooling by about 2℃.

Curtain wall design
Curtain wall design：
Its surface is fully paved with aeolian bell-like sensors, and, when there is a breeze, the facade dances with the breeze in no tangible shape, exactly conforming to the intangible and non-material properties of “power”. This effect can be realized during the daytime entirely through natural wind without needing any energy; during the nighttime, the LED screens behind the sensors flash in different patterns, conveying a mysterious and dreamlike visual effect. The LED matrix in the inner layer of the electric box can play HD videos, while the yarn-like transparent effect of the PVC surface in the outer layer creates a sense of floatation for the building. The light and electric box on the facade inclined wire structure jointly depict the dynamic contour of the entire building.
