Canada|Southwest Fourth Street Underground Passage Lightingseo Upgrade
Underground passages are a common feature of western Canadian cities, and they are common but essential urban infrastructure. The railway that appeared in the 1880s shaped the current core area of Calgary, and the main railway passage split Calgary in two, separating the city center from the adjacent Alberta area. Pedestrians, cyclists, and car drivers from the south can only enter the city center through the sinking "entrance" of the underground passage. Although these underground passages were initially considered safe passage facilities, the irony is that they have become the most uncomfortable public space in Calgary, and the two blocks where the Southwest Fourth Street Underground Pass is located are no exception. In 2010, Calgary promulgated urban design guidelines for underground passages in the downtown area, and now the special underground passage on Fourth Street is the primary renovation project. Limited accessibility, poor lighting conditions (especially at night and winter), pedestrian safety, and overall aging require thorough solutions to provide people with safe, comfortable and attractive public spaces.
As the pedestrians walk towards the first section of the underground passage, they pass through the "perception space", followed by the "reflection space", and then the middle part of the "dialog space" that opens up to the sky. The underground passage introduces vivid lighting and color effects, echoing the flow of people passing through the two-way underground passage, creating an evocative and long-lasting beautiful experience.
The designer chooses materials with reflection, diffuse reflection and light collection properties. The shell is equipped with interactive lighting equipment. The lamps purchased in the project are RGBW wall washer, RGBW floodlight, RGBW linear lamp and customized LED street lamp with Canadian minimalist style, and the material is made of reflective aluminum frame, 8 mm facing pedestrians Tempered laminated safety glass (with a translucent middle layer that diffuses light), thermoformed translucent polycarbonate panels and coatings hanging on existing concrete facilities. Zinc steel bracket. The designer also ensures that public art installations can be operated at night and during the day, and all lamps are programmed using the 512 lighting system control, which can be displayed in multiple modes.
