When rising energy costs threatened to close a local ice rink, a waste heat recycling system was designed that paid back in 24 months while extending equipment life and saving millions of gallons of water.
I was talking with John, the operator at the ice storage plant. Was he ever glad he had this ice storage plant; it was going to save him a fortune! Then I said to him, “Excuse me, I must be missing something. It appears that there is no ice in the ice storage tank.”
Audits tend to conclude with calculated or estimated savings based on little hard data, often biased toward capital improvements sold by the auditor. Capital projects should be the last step in any energy savings effort, not the primary objective.
In this second installment of Bill Holmes’ interview of former C-suite executives at large corporations, they determine that it’s a mistake to think that flattening out of annual savings means the energy management team has done its work and is no longer needed.
The master of using complex apparatus to perform simple tasks would be proud of many older control systems. Here’s how one engineer learned to cut through the resulting clutter to achieve award-winning energy efficiency.
If you’re spending much on energy, monitoring and managing it will provide rapid and lasting returns. But here’s how I learned the hard way that’s true only if you have – and keep – the support of top-level management.
