Soothsayer Says: Eight Predictions for the Energy Industry

By Energy Rant No Comments
If it’s worth doing, it’s worth doing now. That quasi-cliché is why I have never had a New Year’s resolution, and I’m not going to start in 2021, but I can review the past and forecast (guess) the future. Soothsaying is part of my job, and I’m at least as accurate as next week’s weather forecast. At the start of 2020, we had just reorganized, defined who we are, what we do, and why we do it. Sounds simple, right? What is your personal purpose? What do you value? What makes you tick? Keeping it concise is very hard. Our…

Natural Gas Savings, Traps, and H Vacs

By Energy Rant One Comment
I flipped open AESP’s annual magazine to pick up a topic for this week. I chose the last article on natural gas programs. I’ve always found it interesting that folks perceive natural gas to be an enigma for finding savings. If natural gas is being used, the potential for savings is not more difficult to find than electricity savings. Steam “Traps” Let’s start with steam traps. Programs that maintain and replace steam traps are akin to electric programs that fix compressed air leaks.Traps capture things, right? Mousetrap. Ant trap. Beartrap. Ackbar trap. However, a steam trap doesn’t trap steam. It…

Commercial HVAC – Retrofit v New Construction: Apples v Poutine

By Energy Rant No Comments
This post is the main course following last week’s appetizer that covered some complexities of deep energy retrofits for homes. The thrust of that post was that even retrofitting homes requires considerations of many things that have nothing to do with energy – just to achieve desired energy results. This week, we are advancing the subject to commercial buildings. Case Study: 100 Year Old School Let’s start again with a 100-year-old middle school shown nearby. This building has already had a deep energy retrofit, and I’ll explain how to tell later (below). I pulled this building out of my memory…

HVAC’s Cure for Cancer

By Energy Efficiency, Energy Rant 2 Comments
In January, I wrote about code compliance and that while energy codes keep ratcheting down energy intensity in theory, reality is misery.  That post was a thinly veiled advertisement for my AESP National Conference session in the Lion’s Lair, and that presentation can be seen here.  My Lion’s Lair proposal was a thinly veiled pitch to fix what would be the equivalent of curing cancer for commercial HVAC systems. The cancer is the widely used variable, air volume system.  Another boondoggled application of one such system triggered this post.  The boondoggle was part of an evaluation we are doing on…

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…

Tax Deduction Pennies

By Energy Rant, Tax Stuff No Comments
Recently, we received our umpteenth “request for proposal” (RFP) to provide the engineering required to capture the elusive $1.80 tax deduction on new or remodeled buildings.  We spend a lot of time, money and effort to drive business through our doors but I’m not sure I want to see another one of these. Like the rest of the universally incomprehensible tax code, the engineering piece of this is relatively complex.  If we did this all the time, it wouldn’t be a problem.  But it seems we get the next RFP just as the rules are overwritten in my long-term memory…
