Program Secrets for Large Commercial and Industrial

By Energy Rant No Comments
Maybe it’s the Implementation Contractor Classic golden opportunities in retro-commissioning include fixing the root cause of the problem rather than trying to treat the symptoms. For example, it may be too cold in a space, so what should be done? Turn up the hot water temperature, of course! No. The problem could be any number of things like a new partition (wall) being installed, isolating one space with a diffuser from another space that has the thermostat. Or my favorite – parking a 1 kW printer under the temperature sensor. We were RCx geniuses in ha school. When our room…

Retro-Commissioning v Commissioning; Similar Purposes, Vastly Different Approaches

By Energy Efficiency, Energy Rant One Comment
Last week, I was reviewing a scope of work for retro-commissioning, also cleverly known as RCx – and it moved me to pulling hair out by the fistful.  “That’s it”, I thought.  “I’m going to relieve my rage on next week’s Energy Rant.”First, there is the infamous flow/process chart for completing an RCx project.  As you may infer, I am not fond of the “Planning Phase”.  In fact, it seems this process was developed by a program implementer for the program implementer (to spend more time and thus make more money while achieving little more than wasting time). Retro-commissioning has…

True or false: It’s easier to teach Pablo Picasso how to paint a house than it is to make a house painter into a Picasso-grade painter/artist.  For the answer, keep reading. I was sitting in a session at last week’s AESP conference sipping my weak overpriced Starbucks when I almost sprayed a mouthful on the bystanders sitting in front of me.  Not one, but two guys opined that it is easier to teach, for example, a refrigeration expert retrocommissioning than it is to teach a retrocommissioning/energy expert efficient refrigeration.  Allow me to demonstrate with an example, a true story. A…

The More You Spend, The More You Save

By Energy Rant, LEED, Retrocommissioning (RCx) 2 Comments
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…
