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
Currently open to medium sized and large manufacturers only.
Innova Engineering has performed several audits, which assisted clients in receiving grants under NOFA
07-4 with the state of Ohio. 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.
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.
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.
