This project is located in a BMW 4S store in New Zealand. We constructed a sunshade canopy using louver on the roof, which effectively shields the sun-facing side of the building, ensuring the indoor light transmittance and providing some ventilation at the same time. The Swaged trafficable louver also have a certain load-bearing capacity and can support the weight of one or two people, enabling them to carry out some cleaning and maintenance work on the louver.
