The stadium was renovated for the Beijing 2008 Olympic Games, for the hosting of the football games and athletics finals. In the renovation the number of seats was doubled to 40,000 and a roofing structure was added, which was fitted with Sunlite Solar-Control multiwall polycarbonate panels. The panels were selected for their cool lighting benefits to the match the metallic roofs of other venues in the complex. The roof’s inner rim was fitted with clear panels to avoid shadowing of the sport ground.
