Green infrastructure focuses on cost-effective, living, upstream solutions. And there is no-where farther up stream than the roof!

Green infrastructure is so powerful because it harnesses the simple solutions of nature to provide primary and secondary benefits

Challenge: achieving a pre-development hydrologic regime in the city.

We measure, quantify, and validate the effectiveness of green infrastructure. We think the industry benefits from this de-mystification .

We help design teams with better data so they can utilize green roofs confidently by maximizing detention benefits , with ROI for the developer and the environment.

Assembling a green roof cassette for testing.

Responding and adapting to our climate requires innovation , and the best ideas may come from anywhere!

We help manufacturers and inventors evaluate their sustainable solutions , through rigorous testing and monitoring.

Challenge: Beauty, performance, and durability

Green infrastructure is alive! Our work is holistic, including soil biology and water quality .

Humanity is moving to cities. Despite this, we often overlook the biology and chemistry of our urban ecosystems We aim at unlocking some of these mysteries and harness them for good.
