Last week these columns featured Wal-Mart and its silencing of critics via green and sustainable business practices. Are they really saving energy compared to their peers? Skylights, dimming fluorescent lights, and LED refrigerated case lights triggered by occupancy sensors – but what’s the totality? Lexus makes hybrid vehicles. One is a $110,000 sedan with a 5 liter V8 with fighter-jet horsepower weighing in at 20 miles per gallon. A Caterpillar earth mover may get that kind of highway mileage. The point is, a facility / organization can be green in name only. Note that in no way am I inferring…

Most energy efficiency programs are required by regulators to be evaluated to ensure ratepayer money is being spent wisely and reported savings are being achieved. If only such oversight were to happen for the millions/billions/gazillions being shelled out to state and local governments in the name of energy efficiency. State and local governments have Amazon-wide budget gaps to fill, and I can assure you that earmarks (dirty word) for energy efficiency will find their way to plug budget holes to keep buildings open, replace roofs, buy new lawn mowers and pickup trucks, and avoid staff reductions. We in Wisconsin have…

Talk about an oxymoron. Years ago this was a favorite saying of my roommate and I as we lambasted dopey ads on TV, on paper, or over the airwaves. Fewer years ago, once I got into this energy efficiency profession, I was speaking with a utility energy-efficiency program guy who frequently interacts with regulators. This was during a stakeholder meeting for quantifying energy saving potential by sector and by technology. (technology = lighting, furnaces, chillers, etc.) Knowing buildings systems rarely work as they are supposed to, I asked, “Have you considered retrocommissioning (RCx) as an energy efficiency program?” His answer…

Studies have shown that LEED buildings are no more efficient and have no less of a “carbon footprint” than the average building of its peers. I remember reading an old guy’s rant in one of the 20 building engineering and architecture magazines I get. He was grousing that the reason is because there tends to be a lot more glazing and over-ventilation of LEED facilities, along with some other stuff I don’t remember. Apparently, the guy was a proponent of living and working in igloo coolers with no connection the outdoors, which is a big deal for me and everyone…
