The World’s Largest Green Roof.®

Sustainability — without the upfront costs
Underneath the world’s largest green roof, SubTropolis boasts an Energy Star 100 rating and offers unique environmental advantages. The natural temperature and humidity control from the limestone reduces utility costs by up to 70%, dramatically reduces building materials, and creates a nearly disaster-proof facility.

Green before it was cool to be green.®
As early pioneers in adaptive reuse, our SubTropolis team has proven that smart environmental stewardship can supercharge operational and cost efficiencies for businesses of all types. Harnessing Missouri’s natural limestone environment allows us to use fewer building materials, conserve energy, and provide stronger protection than any traditional surface facility — all of which create cost savings we pass on to you.
