Getting to Zero — Illinois

Are you ready to get on the path to zero?

We're working to make net zero buildings feasible, affordable, and commonplace in Illinois.

Illinois Green is tracking and mapping the status of verified zero energy, carbon, water and waste projects throughout Illinois. We are excited to work with project teams to develop educational content, publish case studies, and provide recognition at our annual awards program each October.

View projects across the U.S. actively pursuing zero energy verification on NBI’s Getting to Zero Buildings Database.

Verified Net Zero Energy Buildings in Illinois

Projects are featured on the Net Zero Honor Roll when they are verified net zero energy through the New Buildings Institute's database. Buildings on the Honor Roll are recognized annually in October at Illinois Green's Limelight Gala.

Adlai E. Stevenson High School East Building Addition

Lincolnshire, IL

The Adlai E. Stevenson High School East Building Addition is the first verified net zero building in Illinois. The addition serves as a living laboratory through on-site gardens. The high performing project incorporates best practices across architecture and engineering including a large photovoltaic array that generates 545 MWh-year, resulting in a project that produces more energy than it consumes (-3.75 kBTU/sqft-y). The base building, without photovoltaics, has an efficiency of 32 kBTU/sqft-yr.

Net Zero Buildings Watch List

Projects are featured on the Net Zero Watch List if they are pursuing a net zero energy certification and have been approved by their municipality/board to move forward. Eligible certifications are Phius ZERO, ILFI Zero Energy, or LEED Zero. When projects receive net zero energy verification after a 12-month performance period, they move to the Net Zero Honor Roll (see above).
