Take-home
DCEO has an incentive program for saving gas and electricity
SEDAC has a free building energy assessment
SEDAC promotes the DCEO incentives, but our assessment isn’t required to apply for the DCEO incentives Kelly, Don, and Carol can also help with identifying
opportunities and applying for the DCEO incentives
Sponsored by IL DCEO and investor owned utilities Program Goals
Reduce the cost of doing business Demonstrate the cost effectiveness of energy efficiency
strategies Support job creation and retention in Illinois Support electric and natural gas reliability Reduce pollution Connect owners with utility programs

All services are FREE to the building owner!
The Energy Assessment Process Once you determine that you would like to
have an energy assessment, simply fill out the SEDAC application found at www.apply.sedac.org
Submit electronically, fax, or email What happens next will vary depending on
the project. This presentation is a sample of the typical project and what you can expect.
Application
The form is simple You must include
information marked with a red star
The rest is really helpful. But we would rather get you started than wait.
Call if you have questions!
An Energy Specialist will be assigned Within two weeks an energy specialist will contact
you and talk with you about your project. A few things we will need to know or they will ask for
Your goals (if you have formulated them yet) What the building is (school, public works, city hall) Size If you have drawings or a plan of the building Any equipment lists that you have
HVAC Motors lightings
Most important! Utility bills At least one year, but two are preferred Both supply and delivery will be needed
Send this information
The Energy Specialist will review and analyze this information Graph bills to look for problems Benchmark to see how you are doing in
comparison to others Look at aerial photos online to find out some
information about the building Depending on the work load and the time
frame in which you need information, it could be 4-6 weeks to get through this phase.
All of this analysis will be included in your final report

On the day of the site visit, we will…
Meet with site representatives to explain the program
Finance and Maintenance Reps
Make sure we understand the goals and expectations of the client
Tour the building (2-4hrs) Review some basics of what
we saw Ask if you have questions
Short List
After the site visit… A preliminary list of strategies that we want to
review for the specific building will be sent to you within two weeks. This list will allow you to give feedback if there is
something missing or incorrect Allow you to get a jump start on implementation
and incentives At this point, we can determine the level of
detail required for the final report.
The Report
All of this information, along with an explanation of each ECRM that is recommended will be put into a report
The report will most likely include Executive summary Background information Benchmarking and utilities ECRMs Economics Other information as
necessary We will follow up
quarterly to assist
