Built initially for the 1962 World's Fair, this iconic structure was retrofitted from 2021 to 2024 to become the world's first net-zero certified stadium. This profile dissects the preservation of the historic 44-million-pound roof combined with a completely brand-new underground facility designed using a closed-loop geothermal platform.
The mechanical core operates on a 100% electrified energy grid, eliminating all fossil fuels from building heating, cooking, and mechanical systems.
