Chicago Sustainable Development Policy Handbook
The purpose of this handbook is to describe the sustainable strategies that development projects must choose from to comply with the Chicago Sustainable Development Policy. The handbook provides:
- A definition of each sustainable strategy
- A description of the documentation required to verify compliance
- Links to more information about the strategies
There are two compliance paths available to meet the requirements of the Chicago Sustainable Development Policy. The first pathway involves earning the required number of points without achieving any of the listed building certifications. The required number of points must be achieved from the Menu of Sustainable Strategies explained below.
The second pathway is for projects to achieve one of the listed building certifications. Projects obtaining one of the certifications will start with a certain number of points depending on the type of certification and in certain cases the level of certification. The remaining number of required points will need to be reached through the strategies listed in the menu. Certain strategies are not applicable (NA) because they will have been met by obtaining the certification.
The strategies in the menu have been categorized as follows: Health, Energy, Stormwater, Landscapes, Green Roofs, Water, Transportation, Solid Waste, Work Force and Wildlife.
Strategies
1. Health
1.1 WELL Building Standard
The WELL Building Standard™ is an evidence-based system for measuring, certifying and monitoring the performance of building features that impact health and well-being. WELL is administered by the International WELL Building Institute™ (IWBI), a public benefit corporation whose mission is to improve human health and well-being through the built environment.
Compliance Documentation: Provide WELL precertification award OR proof of registration and checklist of targeted WELL features.

2. Energy
2.1 Design to earn the Energy Star
The U.S. EPA's Energy Star program has developed energy performance rating systems for more than 80 building types. These ratings, on a scale of 1 to 100, provide a means for benchmarking the energy efficiency of specific building types against the energy performance of similar facilities. A score of 75 or higher is required to earn the ENERGY STAR recognition. Once built, these buildings will use, on average, 35 percent less energy than comparable buildings nationwide.
Compliance Documentation: Provide a Statement of Energy Design Intent. The Statement of Energy Design Intent (SEDI) is a two-page summary in PDF format of the design energy inputs and results data that can be generated using either Portfolio Manager or Target Finder. A score of 75 or higher is required to achieve Energy Star and meet the requirements of the Chicago Sustainable Development Policy.

2.2 – 2.5 Exceed Energy Code by 5%-40%
This strategy involves exceeding the baseline model currently required in the Chicago Energy Transformation Code by a minimum of 5%. Additional points will be provided according to how much the project exceeds the current code requirements. The points associated with this strategy are cumulative so a project can only choose one based on how much it is exceeding the code requirements.
Compliance Documentation: Provide a signed and stamped letter from the project’s architect or mechanical engineer pledging the project will exceed the requirements of the Chicago Energy Transformation Code by a specified amount and one of the following to verify how the project will exceed the code:
• COMcheck certificate report – Prescriptive path
• ASHRAE Energy Cost Budget (ECB) Compliance Form – Performance Path

2.6-2.7 Onsite Renewable Energy
Onsite renewable energy includes solar power, geothermal power, wind power or combined heat and power (CHP). A project must provide onsite renewable energy capacity to meet at least 3% of the total modeled energy use for the project at full occupancy. Additional points can be achieved according to how much capacity is provided. The points associated with this strategy are cumulative so a project can only choose one based on how much onsite renewable energy capacity is being provided.
Compliance Documentation: Submit the results of an energy model documenting the percentage of the project’s total modeled energy use at full occupancy that is being provided by onsite renewable energy systems.

5. Green Roofs
5.1 and 5.2 Green Roof 50-100%
A green roof is a conventional roof that is covered with a layer of vegetation. There are multiple benefits to green roofs. Green roofs absorb stormwater that would otherwise drain into the City’s overburdened combined sewer system, they lower urban temperatures thereby helping to reduce the City’s urban heat island effect, they supply habitat for wildlife, they provide additional insulation and they lengthen the life of the roof’s membrane.
A project can earn 10 points if 50-100% of the building’s net roof area is covered with vegetation. It can achieve 20 points by covering 100% of the net roof area. Net roof area is defined as the gross roof square footage area minus the square footage of area used for mechanicals, maintenance pathways, window washing systems, swimming pools and skylights. Up to 10% of the required green roof square footage can be hardscape if the roof is to be used by the tenants of the building.
An additional 10 points can be achieved if the project’s green roof includes one of the following characteristics.
• The green roof growing media is at least 6 inches deep.
• The plant list chosen for the green roof contains plants from at least 30 genera.
Compliance Documentation: Each project will need to provide a roof plan illustrating where the vegetation will be located. The exhibit shall also include a table documenting the project’s (1) gross roof area; (2) area being subtracted from the gross roof area; (3) net roof area; (4) area being used as hardscape, where appropriate and (5) a plant list. All projects earning points for a green roof must also supply a copy of a maintenance agreement/contract for the green roof for a minimum of two years.

6. Water
6.1 and 6.2 Indoor Water Use Reduction
Indoor water usage in new buildings and buildings undergoing major renovations as part of the project must be an average 25% less than in baseline buildings. The baseline usage is based on the requirements of the United States Energy Policy Act of 1992 and subsequent rulings by the Department of Energy, the requirements of the United States Energy Policy Act of 2005, and the fixture performance standards in the 2006 editions of the Uniform Plumbing Code or International Plumbing Code as to fixture performance.
Calculations are based on estimated occupant usage and include only the following fixtures and fixture fittings (as applicable to the project scope): water closets (toilets), urinals, lavatory faucets, showers, kitchen sink faucets, and prerinse spray valves.
The water efficiency threshold is calculated as a weighted average of water usage for the buildings constructed as part of the project based on their conditioned area.
Compliance Documentation: Provide a stamped letter from the project’s architect or general contractor committing to compliance with the LEED Credit WE2 and reaching the required reduction of indoor water use to obtain 10 or 20 points.

7. Transportation
7.1 Proximity to Transit Service
Mixed-use developments near transit stations expand access to transit, bring new amenities to neighborhoods, and foster economic growth across the city. A project can earn 5 points if they are located in the area defined in Section 17-10-0102-B of the Chicago Municipal Code.
Compliance Documentation: The project must provide a map verifying the distance from the project’s property line to the door of the transit station. This map must be approved by the Zoning Administrator.
For more information:
7.2 Bikeshare Sponsorship
A project can earn 5 points if it provides financial sponsorship of a bikeshare docking station. The station’s location must be reviewed and approved by the Chicago Department of Transportation (CDOT).
Compliance Documentation: A signed, bikeshare docking station sponsorship agreement between the property manager and the City of Chicago must be provided.
7.3 Bike Parking Residential
The project can earn 5 points by providing at least one secure, indoor bicycle parking space for each residential unit.
Compliance Documentation: The required number of secure, indoor bicycle parking spaces must be verified on the appropriate project floor/site plan.
7.4 Bike Parking Commercial and Industrial
The project can earn 5 points by providing at least two secure, indoor or outdoor bicycle parking spaces for every five automobile parking spaces.
Compliance Documentation: The required number of secure bicycle parking spaces must be verified on the appropriate project floor/site plan.
7.5 EV Charging Stations
The project can earn 10 points if a dual Level 2 Electric Vehicle Charging Station is installed within the project’s site area.
Compliance Documentation: A description of the station must be provided and the station’s location must be verified on the appropriate site plan.

Work Force
8.2 Workforce Development
Conscious workforce development is achieved when nodes of economic development are intentional about sourcing candidates from a jobseeker pool that is lesser advantaged and defined as of minority status, of veteran status, with household incomes below the poverty line, affected by homelessness, or affected by the justice system. There are two options for achieving the 10 points in this category. Each project must choose one option.
Option 1: Qualified Sourcing
A project can earn 10 points if it enters into an operating agreement with a non-profit organization sourcing candidates from the target population and commits to hiring no less than 5% of the workforce created through the project from said population with a potential for long-term employment. Given variables in hiring, the sourcing partner or partners must be prepared to source ample candidates to ensure the best talent match.
Compliance Documentation: Signed MOU with an organization(s) serving the target population articulating their commitment to source candidates and applicant’s commitment to hire. Total commitments to hire must amount to no less than 5% of the workforce created by the project.
Option 2: Strategic Contracting
A project can earn 10 points if it enters into a contract for hire or contract for services with a non-profit or for-profit or hybrid-profit corporation (often called a “social enterprise”), for whom at least 75% of the workforce is of the target population. Depending on the scope of the project, typical social enterprises that may apply are those that offer contract staffing, or those that offer basic general labor with the potential for long-term employment.
Compliance Documentation: Signed contract with a social enterprise where scope of work constitutes no less than 5% of the total workforce created by the project, and inventory of workforce at the time of contract signing to demonstrably prove that the workforce fits the target population.

9. Wildlife
9.1 Bird Protection (Basic)
Chicago Bird Collision Monitors collects data on bird collisions from around the Chicago area. Through empirical observation, they have developed a set of criteria common to buildings that experience a high number of migratory bird and insect collisions. These items either aim to minimize collisions or increase the likelihood of survival after a non-fatal collision. Additionally, the lighting criteria listed seeks to reduce the impact of light pollution on nocturnal migrating animals.
Compliance Documentation: Achieve all appropriate items on the “Bird Safe Buildings: Best Practices Checklist.”
For more information:
http://www.birdmonitors.net/BestPractices.php
https://abcbirds.org/program/glass-collisions/bird-friendly-design/
9.2 Bird Protection (Enhanced)
Collision with glass claims the lives of hundreds of millions of birds each year in the United States. Birds that have successfully flown thousands of miles on migration can die in seconds on a pane of glass; impacts kill fledglings before they can truly fly. Because glass is dangerous for strong, healthy, breeding adults, as well as sick or young birds, it can have a particularly serious impact on populations.
The American Bird Conservancy, in partnership with New York City Audubon has developed a guide to help architects, planners, and developers minimize the threats of the building environment on bird populations.
Compliance Documentation: Provide a stamped letter from the project’s architect or general contractor committing to compliance with the Bird Collision Deterrence LEED pilot credit SSpc55. Please note that the performance monitoring plan is not required unless needed for other certification purposes.
