Illinois Energy Conservation Code Training

Request an Energy Code Workshop. Now is your chance to request an Energy Code Training Workshop from SEDAC. On behalf of the Illinois EPA Office of Energy, SEDAC offers free workshops for building professionals, code officials, professional organizations, and more. We can present during your organization's regular meeting time or schedule a separate workshop in your area. 

Our most frequently requested topic is the 2018 International Energy Conservation Code Updates, since the 2018 IECC will go into effect in early 2019. We are also happy to present on other topics related to the energy code, such as compliance paths, air sealing and insulation, lighting, and more. What would you like to learn more about? Call SEDAC at 800-214-7954 or email us at energycode@sedac.org to discuss possibilities! 

Questions about the Illinois Energy Conservation Code.  Find answers to frequently asked questions on our Energy Code FAQ page , or call us at 800-214-7954 or email us at energycode@sedac.org for technical support and individualized guidance. 

Online Education. SEDAC offers  free  online Illinois Energy Conservation Code Training Modules that can be accessed anytime, anywhere. These modules provide introductory-level information about the Code for building professionals and code officials. You can receive continuing education credit from the Association of Energy Engineers (AEE) and the Building Performance Institute (BPI) for completing our courses. Courses can be accessed at sedac-energycode-training.thinkific.com

Funding for the Illinois Energy Conservation Code Training Program has been provided in whole or in part by the Illinois EPA Office of Energy.
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.

Energy Saving Tips for Waste Water Treatment Plants

E very wastewater treatment plant we examine is unique, and we tailor our recommendations to your needs, suggesting cost effective strategies to help you save energy and money. 

Here are some of our top recommendations: 
  • Aeration. Use dissolved oxygen sensor aeration controls and fine bubble aeration to reduce energy consumption.
  • Blower. Consider upgrading to a high-efficiency, variable capacity blower.
  • Electric motor control. Use variable frequency drives on aeration blower motors and pump motors.
  • Flow controls. Adjust flow rates during low and peak times for more consistent, optimized operations.
  • Wastewater system piping. Inspect piping for leaks and repair as needed to reduce pumping energy requirements.
  • Lighting. Choose efficient lighting sources, such as LEDs, and occupancy controls.
  • Heating and cooling. Tune up existing equipment. Use high efficiency condensing boilers and furnaces of 92% efficiency or better. Use high efficiency air conditioning equipment with an outdoor air economizer.
  • Temperature setbacks. Use automatic or manual controls to adjust temperature settings and system operation according to time of day and building loads. 
SEDAC Quick Tips


In the last SEDAC newsletter, the importance of benchmarking was recommended as a first step in energy efficiency planning. Benchmarking not only provides a snapshot of how a particular facility is performing at a certain point in time, but it also allows it to be compared to similar type facilities. This comparison, although rather approximate, still provides an estimate of how a facility is performing.

Benchmarking usually involves taking a year's worth of electrical and natural gas consumption, converting it to thousands of BTU's (kBtu), and then dividing by the gross square footage of the facility. The resulting value, called the Energy Use Intensity (EUI), measured in thousands of Btu per square foot (kBtu/sf), is a common metric so that buildings can be compared to one another. It's how a 200,000 sf school can be compared to a 50,000 sf school. Naturally, common ranges for EUI's vary from one building type to another, e.g. the EUI for a non-cooled warehouse will be very different from a hospital.

The square footage used in the derivation of the EUI is the gross square footage. That is the footprint of the facility. The dimensions are taken from the exterior of the facility. If the architectural drawings of the facility are available, they usually contain the square footage. If not available, taking actual dimensions is best, or if not too complicated, Google Earth can be used to derive an approximate square footage.

If you would like to benchmark your facility and have questions, please call SEDAC at 800-214-7954 or email us at info@sedac.org. We can help.
