Advancing Policy


A group of people are standing around a table in a room.

We convene green building professionals to advance high performance buildings for all.

Reducing building emissions is crucial for meeting state and local climate goals.


To overcome barriers to net zero adoption, we will engage our network of building professionals to develop new policies, like net zero building codes and building performance standards, and educate policymakers about meaningful solutions that will help overcome roadblocks and incentivize net zero buildings.

Our Current Policy Goals


Energy Benchmarking

You can't improve what you don't measure.


Benchmarking is the first step towards reducing energy use. Energy benchmarking means tracking a building’s annual energy and water use by using a standard metric to compare the building’s current performance against past performance, and to similar buildings both locally and nationwide. These comparisons help building owners, operators, and managers to identify and implement energy efficiency opportunities, increase occupancy rates and property values.


This simple process has a major impact — buildings in Chicago reduced energy use by 5.2% and saved $15.1 million annually after a benchmarking ordinance was adopted.

Building Performance Standards

Building Performance Standards (BPS) are an innovative new policy approach to achieve efficiency and decarbonization in existing buildings.


A BPS is a policy that sets specific deadlines for existing buildings over a certain size to achieve quantified standards of performance across energy use, water use, and/or greenhouse gas emissions. The standards become more ambitious over an extended period oftime, driving continuous, long-term improvement in the building stock.


Every building will undergo repairs and renovations through it's lifecycle — Performance Standards simply ensure that they are done smartly and sustainably.

Stretch Energy Codes

Stretch Codes are a pathway for municipalities to raise the energy efficiency baseline in their community. 


Local governments can adopt the Stretch Code in place of their base code. These new codes have been developed by the state to set higher efficiency targets and add readiness standards for the installation of electric technologies.


Adopting the Stretch Code would save the average homeowner an projected $250 a year and provide a return on investment in just over 10 years. 


The Illinois Climate Bank has made $200,000 grants available to communities for Stretch Code Adoption.

At the start of 2025, I told our members that we can build a movement of green building advocates that can continue the progress made in Illinois for high-performance building, regardless of what happens in Washington D.C. Over the last year, you’ve proven me right. While elsewhere green building and clean energy goals have been put on pause, Illinois has continued the fight and won three huge victories that usher in historic investment in clean energy and green buildings and raise the bar for building performance, completely changing the landscape for what is possible in this industry.
