As the 15th National Games draw closer, construction and renovation of the competition venues are accelerating. On April 3rd, reporters accompanied He Jingtang, an academician of the Chinese Academy of Engineering, on a field visit to the completed main venue, the Guangdong Olympic Sports Center, to learn about the highlights of its renovation.

The project was designed by Academician He Jingtang and his team, including renovations of the Center stadium and the Swimming and Diving Hall, the construction of a new Sport Command Center, and upgrades to the overall landscape. In terms of environmental protection, the team adapted the renovation to the Lingnan region's climate and the functional requirements of sports venues. They focused on three key elements of heat insulation, ventilation, and sun shading to create a more climate-adaptive public space for Lingnan. About 2,300 square meters of photovoltaic panels were installed on the floating eaves at different levels of the structure, providing a total capacity of around 368 kW and reducing carbon emissions by an estimated 191 tons annually.

Upon entering the stadium, the most striking feature is the ribbon-like open roof structure. "We added a PTFE tensile membrane beneath the original roof to conceal the exposed steel structure and create an ethereal visual effect," explained He Jingtang. This effect was realized through precise structural calculations, wind tunnel tests, and the use of lightweight new materials. Also, floodlight projection was employed to create dynamic visual effects.

The stadium's exterior integrates traditional Lingnan architectural features, such as extended horizontal eaves and banded french windows. According to He, the design emphasizes the characters of Lingnan. The interior ceiling aligns with the height of the outer curtain wall and uses custom U-shaped aluminum trims to create a sleek elliptical form.

Greening was another key component of the renovation. An additional 39,000 square meters of greenery was added, bringing the total green space to 180,000 square meters. "We aimed not only to serve the Games but also to create a daily activity space for the public," said He. New shaded fitness zones, a circular running track, and multifunctional areas have been included in the venues to enhance the public experience.

十五运主场馆改造亮点：每年减少191吨碳排放

随着十五运会的脚步越来越近，各个赛事场馆建设、改造进度条不断刷新。4月3日，记者随中国工程院院士何镜堂实地探访已完工的主场馆——广东奥林匹克体育中心，了解其改造亮点。

本次项目由何镜堂院士团队设计，改造内容包括中心体育场、游泳跳水馆，新建赛事指挥中心，并提升整体景观。绿色环保方面，根据岭南地区气候和体育场馆的功能特点，设计团队从隔热、通风、遮阳三大要点进行改造，提供更适合岭南气候的公共空间环境。借助各层飘檐等设置光伏发电板约2300平方米，容量约368千瓦，每年可减少191吨碳排放。

走进体育场，最引人注目的是状如飘带的开放式屋盖。何镜堂介绍：“我们在原有屋盖底部基础上增加了PTFE吊膜，遮挡裸露钢结构，呈现‘飘逸’视觉效果。”为实现这个效果，团队进行了精密计算和风洞试验，并使用轻质新材料，同时通过泛光投影，打造出动感光影。

体育场外观融合岭南建筑特色，如水平挑檐、带型落地窗等。何镜堂表示，设计强调岭南气质，室内吊顶与外幕墙统一高度，采用定制U形铝材封边，呈现挺拔椭圆造型。

绿化是此次改造的重要部分。项目新增3.9万平方米绿化，总绿化面积达18万平方米。何镜堂指出：“我们不仅为赛事服务，也希望打造群众日常活动空间。”场馆内增设林荫健身点、环形跑道、多功能空间，提升市民使用体验。
