One of the primary challenges was the stadium's large curved roof, which required the use of custom-designed photovoltaic components, according to Guo. In total, the project utilized 129 unique component sizes to accommodate the roof's intricate geometry.

Originally built in 1959 and spanning over 80,000 sq m, the Workers' Stadium has hosted numerous international sports and entertainment events. The renovation project, launched in 2020 by the Beijing government, was designed to align with the city's urban development goals.

By integrating modern sustainability features with the original architectural design, the updated stadium underscores its cultural and social significance while showcasing the potential of green technology in building construction.
