Indestructible Code Compliance Villains

By Energy Rant No Comments
In case you missed last week’s post, you’ll need to go back and review the setup for this week’s demonstration of code challenges and mistakes. To summarize, I have an installed ENERGY STAR-qualifying 95% AFUE (efficient) boiler with a brazed plate heat exchanger, hot water reset control, and a variable firing rate that ranges from 20% to 100%. That firing range is even better than code requirements. The system is a duded-out energy code breaker in theory. Let’s look at what went wrong in order. I have a Nest cam in the backyard and a Nest thermostat for the boiler.…

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…

Paint by Numbers EE

By Energy Efficiency, Energy Rant No Comments
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…

LEED and the NOT Happenin’ Savings

By Energy Rant, LEED No Comments
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…
