7 Ways to Reduce Energy CostBy Jon Miller | Post Date: February 13, 2009 5:19 PM | Comments: 5 Earlier this week Ron Pereira wrote about 7 ways to reduce costs at the Lean Six Sigma Academy blog. He ht a nerve and kicked up quite storm of more than a dozen comments when he suggested that frequent flyer miles be saved by the company and redeemed to reduce business travel cost. Let's see if we can offend anyone's sense of entitlement by suggestion 7 ways to reduce energy cost.
It's cold in my office year round, and I complain about this constantly. But if it was warm and stuffy I would still complain. If it was just right I'd still complain about the smell, because once you have the kaizen mind you are sensitive to small% A few comments on the water temperature. First energy savings. I wouldn't expect mixing hot temperature water with low temperature water to be more wasteful than heating the water up to the desired temperature in bulk. The same energy is required in either case. Hot water sitting in uninsulated lines will lose heat faster if it's hotter, that might be an argument for better insulation rather than lower temperature. A bigger issue is safety. Water above 60C is a scalding risk, water below 50C is a risk for bacteria contamination. The recommendation appears to be to store hot water above 60C and deliver it below 50C. Maybe point of use heaters are the optimum solution? In the meantime it looks like we get to choose between risks. For your reference the Canada Safety Council has some discussion on this. http://www.safety-council.org/info/home/hotwater.html Robert Poster: Robert Adsett | Post Date: February 15, 2009 6:45 PM That's a good point Robert. One of my neighbors mentioned an infrared (?) spot heater attached to the faucet, shower head etc. It heats cool water before it comes out, so they don't need to store hot water. Sounds pretty fantastic, just in time hot water.

Green conscious clearly does not equal functional intelligence (i.e., common sense). Poster: whatever | Post Date: July 16, 2009 11:06 AM You read it right w/e, I test the water temperature, though these days it's mostly unconsciously before washing hands. It's not as though I crank the faucet all the way to see how hot I can make the water. In my experience many hotels, airport restrooms, and company restrooms have the water set to max temp the moment you turn it on. That was my point. Restaurants, not so much... makes one wonder.

Hi Jon,
Interesting post. :)
A few years back, I was in charge of ISO 14001 registration for a company and I had to go through most of the steps you mentioned here. I would like to expand on #2, since that is an area most of us neglect. The phenomenon called phantom energy where electric appliances drain energy even when they are off or in hibernation can act as a significant source of energy wastage as you mentioned.
Our first step was to start with computer monitors and then computer itself.
