#10. Energy audit saved $125,000 CAPEX

Reduction of air exhaust from refrigerated room reduced cooling load and eliminated need for refrigeration plant upgrade

#9. Energy audit finds $20,000 in energy savings at a cost of a 30 ft pipe.

A perfectly efficient machines can still waste lots of primary or secondary utilities. A complex utility audit routinely uncovers how water, heat or 'cooling' can be reused. Hot water reuse at poultry slaughter house Two industrial poultry processing procedures were set in adjacent production space - vacuum pump and scalding. [...]

#8. Energy audit busts ‘Nothing to save, Everything is automated’ belief

A common objection to doing an energy audit is that 'Everything is fine'. This is rarely the case. Here are two examples when audit uncovered saving opportunities that clients did not know existed because they believed everything was in perfect state already. Efficient equipment does not equate to efficient operation. Sanitation staff turned [...]

Energy waste is invisible, until you measure it

A prospect informed about a possible massive cost of compressed air leaks responded: “What leaks? I do not hear hissing noise from compressed air leaks on the floor.” Plant manufactures gravel. Production noise is deafening.  To hear compressed air leak would be a disaster, not only for energy bill, but likely for the whole [...]

#7. 4 sources of energy waste at plants with efficient machines

A common belief is that if plant is equipped with efficient machines it runs efficiently. Unfortunately, this is not always true. Efficiency of components does not equate to efficiency of the whole plant. Common reason for utility waste by efficient machines: Misuse: compressed air used instead of blowers or for cooling, oversized motors, excessive [...]

#6. 6 beliefs about energy efficiency busted by energy audits

We often hear: "Our plant runs at top energy efficiency because we use these procedures and settings and our efficient equipment is fully operational." Just how often is this true? With all due respect to maintenance and operational staff, recommendations of a proper energy audit are based on direct observation of operations and lots [...]

#5. How to reduce energy cost when CAPEX is limited

A lot of energy costs can be saved at manufacturing plant without CAPEX.

#4. Energy savings at manufacturing plant beyond LED, VFD and idling

Complex energy audit does not look at energy alone. It considers how energy use affects core business - production, quality, scrap, employee productivity.

#3. The 4 reasons energy audit is valuable to your business

In previous post of the "Energy Audit Series" we talked about What makes energy audit free and How is energy inefficiency alike health issues. In this post we will dive a bit deeper into how energy audit creates value to companies. I said it before and will say it again: Energy audit by itself [...]

#1. Energy Audit: why bother?

What is energy audit? Energy audit is a consulting project that finds out how your plant can maintain stable production and quality, while using less utilities - electricity, natural gas and water. An audit worth its fees relies on extensive direct measurements, detailed interviews with production and maintenance managers and comparison of energy consumption [...]
