Zhong Guo Fa Zhan Wang·2025-12-12 06:15Core Viewpoint - The Greater Bay Area Science Hall, a landmark for scientific exchange, has officially opened, showcasing international standards in Guangzhou's Nansha district [1][3]. Group 1: Project Overview - The Greater Bay Area Science Hall covers an area of approximately 92,600 square meters and integrates an academic center, science museum, and supporting functions [1][3]. - The design concept "Sailing with a Thousand Sails, Technology at Sea" features the largest wave-shaped continuous welded stainless steel roof in the country, with dimensions of 170 meters in length and 150 meters in width, and a maximum height difference of 21 meters [3][4]. Group 2: Construction and Materials - The project utilized 7,000 tons of steel, with the roof's maximum span reaching 75 meters, divided into 38 triangular grid units to create a fluid wave-like structure [3][4]. - Advanced construction techniques, including 3D laser scanning and intelligent welding robots, were employed to ensure precision in the welding seams, maintaining accuracy within millimeters over a total length exceeding 40,000 meters [3][4]. Group 3: Sustainability and Technology - The building aims to be a "near-zero carbon building," utilizing fluorocarbon-coated aluminum panels and anodized aluminum plates that are resistant to corrosion and require minimal maintenance [4][5]. - The installation of 1,200 square meters of photovoltaic glass on the roof is expected to generate 96,000 kilowatt-hours annually, fulfilling the indoor lighting needs [4][5]. - The cooling system in the underground machine room employs a high-efficiency technology developed by China Railway Construction, improving the energy efficiency ratio from 6.15 to nearly zero carbon standard of 6.8, achieving an overall energy-saving rate exceeding 50% [4][5]. Group 4: Future Implications - The Greater Bay Area Science Hall is positioned as a crucial platform for deepening cooperation in the Guangdong-Hong Kong-Macau Greater Bay Area and is expected to enhance regional collaborative innovation and support the development of an open and integrated technological ecosystem [5].
