HOK's Net Zero Co2urt _01 Net Zero Co2urt in St. Louis, Mo., is a four-story office building with two 300-ft.-long office bars oriented on an east-west axis. The office bars are connected by two 60-ft.-long links that enclose a courtyard. About 52,000 sq. ft. of photovoltaic panels are spread across the roofs of the office buildings and parking garage, as well as integrated into the south-facing shading devices.

The interior courtyard features a green wall and small punched windows that bring exactly the right amount of light into the link connecting the two office bars. Trees are sized to preserve access to natural light.
