Chicago Test and Balance Requirements: Navigating the Energy Transformation Code (2026 Guide)
Commercial Test and Balance in the City of Chicago
In Chicago, Illinois, Test and Balance (TAB) is not just a recommendation—it is a mandatory step for occupancy.
Unlike suburban municipalities that often follow standard state codes, the City of Chicago operates under its own rigorous framework. For General Contractors and Business Owners in the city, understanding the 2022 Chicago Energy Transformation Code is essential to avoiding red tags and permitting delays.
Here is how TAB services apply to Chicago's unique Building Code Compliance, Indoor Air Quality, and Permitting processes.
1. Building Code Compliance: The "Energy Transformation" Era
Chicago is aggressively pursuing decarbonization and energy efficiency, making the 2022 Chicago Energy Transformation Code one of the strictest in the Midwest.
Adherence to Local Codes: The code explicitly sets standards for HVAC system performance, requiring precise verification of airflow and fan power limits. You cannot guess; you must prove it.
ASHRAE 62.1 Compliance: Chicago inspectors strictly enforce ASHRAE 62.1 (Ventilation for Acceptable Indoor Air Quality). TAB verification ensures your "Outside Air" (OA) intake matches the occupancy load, preventing "Sick Building Syndrome."
The Permitting Process: For new construction and renovations in the Loop or neighborhoods, obtaining a Certificate of Occupancy from the City of Chicago Department of Buildings (DOB) requires a certified TAB report. This report is the "proof of work" reviewed by the mechanical inspector before you can open.
2. New Construction & Renovations
Whether you are building a high-rise in the West Loop or renovating a restaurant in Lincoln Park, the "Closeout" phase is critical.
Ensuring System Performance: In new construction, TAB services verify that the RTUs and VAV Boxes are installed according to the MEP Engineer’s design. We verify the physics of the system to ensure efficiency from Day 1.
The Renovation Reality: Remodels often involve moving walls or changing ductwork, which destroys the original air balance. If you change the floor plan, the old airflow data is obsolete. TAB is essential to rebalance the system to the new layout.
Preventing "Comfort Complaints": In commercial projects, improper balancing leads to uneven heating/cooling and "hot spots." We fix these issues before the tenant moves in, saving the General Contractor from costly callbacks.
3. Indoor Air Quality (IAQ) in a Dense City
In a dense urban environment like Chicago, maintaining Indoor Air Quality is a challenge.
Contaminant Control: Properly balanced HVAC systems maintain consistent air circulation, reducing urban contaminants like dust and allergens.
Outside Air (OA) Verification: We verify that your system is bringing in the exact amount of fresh outside air required by code. This prevents carbon dioxide buildup, humidity problems, and stale air issues that inspectors look for.
Sector Specifics: Chicago Public Schools, hospitals, and downtown offices depend on NCI Certified TAB services to maintain breathable, code-compliant air.
