Design idea 

The project is a trial-production workshop and supporting room for the production of range extenders for new energy vehicles. Efficient and concise facade elements are applied to the building. Glass facade is used as the building facade, and aluminum veneer facade are used partially, thus creating a modern, unitized and industrialized modern new energy automobile industry atmosphere, maintaining coordination and echo with the ideal automobile headquarters (current situations) on the south side, forming a continuous and unified urban interface, friendly and humble urban space, and creating a good industrial park style atmosphere.

 Facade design 

 The glass facade system on the standard floor should be bright in vertical direction and hiding in horizontal direction 

The column span of the glass facade for standard floor that is bright in vertical direction and hiding in horizontal direction is 4500mm, and the maximum glass plate is 1450mmX1700mm (2.4㎡); For glass with large surface, 6Low-E+12Ar + 6Low-E+12Ar +6 double-glazed & tempered glass is used, and 6Low-E+12Ar + 6Low-E+12Ar +6 +1.14 Pvb+6 double-glazed, tempered & laminated glass is used for 1050mm division on the ground; the upright column should be the double-span design, aluminum alloy upright column, and the form of opening is external suspended sash window.

 The glass facade system on the first floor should be bright in vertical direction and hiding in horizontal direction 

Due to the large glass plate of the project, the weight of grounding glass is up to 630kg. After a series of evaluation and analysis, it is suggested that aluminum alloy beam should not be provided at the bottom, and the glass should be directly put into the groove, and the concrete structure should bear the gravity of glass. The facade system of the first floor and the standard floor forms a simple facade with agility and internal order.

 Glass facade of foyer 

The largest glass plate in the glass facade part is 6.9㎡, and the weight of a single piece of glass is about 690kg; As the thermal requirement K value of the project is 1.5W/(㎡K), the glass needs to be in the form of three glasses and two cavities, and as the glass plate exceeds 6m2, it is recommended to adopt 12Low-e + 12Ar + 12Low-e + 12Ar +12 double-glazed & tempered ultra clear glass (thermal insulation warm warm edgings).

 Canopy system 

The canopy is vertically divided into 2900mm joints with the glass facade, with a root thickness of 500mm, a front end thickness of 200mm and a cantilever of 3350mm (out of the glass surface). The plate is made of aluminum veneer with a thickness of 3mm, the surface is sprayed with fluorocarbon, the glue joint width is 12mm, and the drainage method is scattered; The preliminary scheme of transverse division width of canopy is 700mm. The canopy is exquisitely designed, which greatly helps the overall beauty and proper shadow effect of the building.
