Energy savings in your facility

Where should you start???
Do you qualify for any grants or incentives to improve the energy efficiency of your facility?
Duke Energy energy efficiency incentives
Duke is currently offering small incentives for lighting retrofits, motor replacements, HVAC replacements
with more efficient equipment and other incentives.
State of Ohio Envinta program (for manufacturers)
Currently suspended. Check back frequently, as this program is supposed to be back online very soon
(current as of 02/2011).
Innova Engineering is a certified facilitator of this program. Call us for more information, 513-721-1234.
Current State of Ohio Energy grants
Currently, the state of Ohio offers grants for industrial heat recovery, combined heat and power and
landfill or biomass methane for electric generation, and renewable energy generation for residences and
commercial properties. As of 11/2010, these programs were suspended to applications. They are
expected back online 07/2011.
Additional resources?
The best resource on the internet is the Federal Energy Efficiency Office for Industry. Start with the
tipsheets, under publications, technical publications, on each system (i.e. steam systems tipsheets).
Another good website is the Portland Energy Conservation. This site has a lot of good information about
commissioning and operations and maintenance savings.
What areas are targets for potential energy savings?
Some sample findings are given below. Many more opportunities exist within your facility to
reduce energy costs with relatively little capital input. Contact Innova Engineering for a
complete energy audit of your facility.
HVAC Systems
There are typically many opportunities within the HVAC systems. Some opportunities related to VAV
systems can be found in the white paper by Maria Ramos, HVAC Control Settings that Save You Money.
Consideration should also be given to getting the system commissioned. Commissioning verifies that the
system is operating the way it was originally intended.
Lighting
Inexpensive: Replace incandescent light bulbs with compact fluorescents. Replace T12s with T8s. Duke
Energy clients can receive an incentive for changing out light bulbs.
Moderately expensive: Replace magnetic ballasts with electronic ballasts. Install occupancy sensors in
areas where occupancy is intermittent.
Moderately expensive: Replace high bay metal halides with high bay flourescents. Very attractive
savings, and Duke offers a rebate.
Motors
Inexpensive: Turn off motor when it is not needed. Install time clock or night setback functionality where
appropriate.
Moderately expensive: Replace standard efficiency motors with premium efficiency motors. This
upgrade typically has a 3 year or less payback .
Expensive: Consider variable speed drives where appropriate.
Fans and pumps
Inexpensive (if a DDC system is already in place): Consider control strategies to reduce operating points
of fans and pumps (adjustment of static pressure setpoints). Evaluate system to minimize simultaneous
heating and cooling.
Moderately expensive: Replace throttle control (inlet vanes on fan, discharge throttling valve on pump)
with a variable speed drive.
Compressed Air
Inexpensive: Reduce operating pressure if allowed by end users.
Evaluate the system during quiet times of no load for leaks in the piping.
Expensive: Baseline compressed air system. Regular operation of one or more compressors may be able
to be replaced by storage tanks, depending on load profile.
Steam Boiler Systems
Moderately expensive: Automate boiler blowdown by measuring actual dissolved solids in the water.
Moderately expensive: Boiler control system.
Inexpensive: Test flue gases yearly, or more often for year-around boiler operation. Tune boiler to
optimum excess oxygen percentage.
