Nestled in downtown Shaoxing, the North Latitude 30 Geographic Pavilion was designed in the 1990s by Academician Cheng Taining, inspired by the Buddhist "stupa" architecture. Plagued by poor energy efficiency and dim night views, it lost popularity. A revamp launched in 2021 made revitalizing its nightscape the core priority. The renovation preserved the original structure to the greatest extent. High-transparency, UV-protective triple-silver Low-E glass was installed and halogen lamps replaced, boosting energy efficiency by 50%upholding the citys cultural context and collective memories. Tucked in an old-town residential area, the pavilions square and landscapes serve as public spaces for the city and community, making a comfortable light environment a key design focus. Lighting design addressed challenges like hidden fixtures and beam angle control. Collaborating closely with the building and curtain wall teams, fixtures were embedded in the curtain wall structure. Precise calculations and adjustments optimized light angles to eliminate glare, cutting costs while creating uniform halos. At night, the building shimmers like a crystal floating in the city center. Upgraded, the pavilion houses a geographic exhibition hall underground and a city caf on the ground, with customized nighttime scenarios. Drawing from Shaoxings "small bridges over flowing waters" and "white walls with black tiles," six soft colors and festive scenes were crafted. Ground LED linear buried lights outline "light veins," linking with internal lighting to highlight geographic symbols. Visitors can activate lights via an interactive app, emphasizing the cultural significance of North Latitude 30. The revamp also enhanced lighting for the Yuan Dynasty Dashan Pagoda in the square. Calculated pole-mounted long-throw lights with 2000K warm yellow light illuminate the pagoda body and crown, complementing the pavilions crystal-clear texture. Today, the renovated pavilion has become a beloved urban landmark for Shaoxing residents.
