Energy Efficiency

Taking steps to cut energy waste can produce immediate savings for businesses. Some steps can be taken with virtually no financial investment, and other steps can have a short pay back period. The Energy Star Program has an excellent publication, "Putting Energy into Profits" (pdf) that can guide businesses in saving money from lighting, heating, air conditioning and office equipment purchase, use and maintenance. Energy Star also operates a toll-free hotline at 1-888-STAR YES for answering questions, providing engineering support and product information.

The Missouri Industrial Assessment Center provides small and medium-sized manufacturers with free comprehensive energy audits through funding from the U.S. Department of Energy. Businesses that have benefited from these audits have saved an average of $65,000 annually in energy costs. Companies eligible for free energy assessments must:

Be manufacturers within SIC Code 2000-3999
Have $100,000 to $2.0 million per year in total energy costs
Have a maximum of 500 employees
Have a maximum of $100 million/year gross annual sales
Lack in-house professional expertise in energy use and conservation.

If your company meets these qualifications and you're interested in an assessment, please contact Missouri IAC Director, Dr. Bin Wu.

Here are some general recommendations for improving energy efficiency from the Department of Energy website:

All Combustion Systems

Operate furnaces and boilers at or close to design capacity
Reduce excess air used for combustion
Clean heat transfer surfaces
Reduce radiation losses from openings
Use proper furnace or boiler insulation to reduce wall heat losses
Adequately insulate air or water-cooled surfaces exposed to the furnace environment and steam lines leaving the boiler
Install air preheat or other heat recovery equipment

Steam Generation Systems

Improve water treatment to minimize boiler blowdown
Optimize deaerator vent rate
Repair steam leaks
Minimize vented steam
Implement effective steam trap maintenance program
Use high-pressure condensate to make low-pressure steam
Utilize backpressure turbine instead of pressure-reducing or release valves
Optimize condensate recovery

Process Heating Systems

Minimize air leakage into the furnace by sealing openings
Maintain proper, slightly positive furnace pressure
Reduce weight of or eliminate material handling fixtures
Modify the furnace system or use a separate heating system to recover furnace exhaust gas heat
Recover part of the furnace exhaust heat for use in lower-temperature processes

The Department of Energy website also contains the Quick Plant Energy Profiler, an online software tool that helps industrial plant personnel quickly understand how energy is being used at their plant and how they might save energy and money.
