Illinois Energy Conservation Code Training

Energy Code Workshop. Attend the 2018 IECC Electrical and Lighting Systems Workshop to learn about the 2018 IECC and get up to date! This SEDAC workshop is offered in partnership with the Central Illinois Division International Association of Electrical Inspectors (IAEI). The presentation will cover the 2018 International Energy Conservation Code (IECC), focusing specifically on the Electrical Power and Lighting Systems sections. Lunch will be served at a cost of $20. 

When: October 11, 2018, from 11am to 3pm (includes lunch from 12-1pm). Check in begins at 10:30am.
Where: Crawfords, 610 West Chestnut, Bloomington, IL 61701
Space is limited, so advanced registration is required. To register, please email Rand Veerman at or call 309.824.7489.

Energy Code Tip: Air Leakage

2015 IECC C402.5 ). Specifically, 
  • Joints and seams must be sealed;
  • Penetrations of the air barrier must be caulked; 
  • Recessed lighting fixtures must be sealed or caulked;
  • Fenestration assemblies must meet air leakage standards;
  • Doors and openings must be gasketed, weatherstripped, or sealed. 
Air leakage requirements are similar for residential buildings (see  2015 IECC R402.4).

Why this is important. Compliance with the air leakage requirements is important not only for energy efficiency, but also for the health and comfort of occupants. Air leakage can lead to interior air quality and moisture problems, especially in humid climates. Water vapor migrating through building assemblies can cause mold and rot, if not managed properly. For people with mold sensitivity, mold exposure can bring nasal stuffiness, coughing, wheezing, eye and skin irritation. For people with mold allergies, compromised immune systems, or chronic lung illnesses, mold exposure can lead to more serious infections.

Wastewater Treatment Plant Efficiency Program 

Find out how you can save energy and money in your wastewater treatment plant.  SEDAC and the Illinois Sustainable Technology Center (ISTC), on behalf of the Illinois EPA Office of Energy, are providing free energy usage assessments to help municipalities reduce the cost of wastewater treatment.

SEDAC Quick Tip: Benchmarking

SEDAC recommends benchmarking as a first step towards energy efficiency. The EPA offers two free online benchmarking tools that you can use: Target Finder and  Portfolio Manager. Both tools track energy and water consumption, calculate energy use intensity, and show how your facility compares to other similar facilities by providing your facility an estimated 1-100 ENERGY STAR score. Which tool should you choose? 

Target Finder   is best for quick-and-easy calculations. It provides a snapshot of how your building is performing, compared to other buildings, and how close you are to target goals. All you need are energy bills and some basic information about your building. No login required.

The following table is from a Target Finder analysis of a high school that SEDAC audited (values rounded). The column labeled Design Project is the high school being evaluated while Design Target is an ENERGY STAR facility with a score of 75, and the final column is a Median Property with an ENERGY STAR score of 50. The results indicate that the high school is performing fairly well, but a reduction in Site Energy Use of 5 kBtu/sf would make it eligible for ENERGY STAR Certification. 

Portfolio Manager is a more robust tool. You must create an account to use the tool, but that provides you with lots of additional features: you can share data with others, you can track energy performance over time, and you can compare a portfolio of buildings.  

The example below is for an office building that has ten years of energy data (values rounded). The ENERGY STAR Score has improved from 53 to 57. Its Site EUI, or energy use per square foot per year, has improved from 82.6 to 79.9 kBtu/sf/yr.  These results show that this facility has room for improvement. It performs slightly better than a median office building, performing at an ENERGY STAR Score of 50, but well below the minimum score of 75 required for ENERGY STAR Certification.

If you have questions about benchmarking, please call 800.214.7954 or email . After benchmarking is complete, we can help you determine the next steps.
