Benchmarking Clowns

By Energy Rant One Comment
It’s Halloween. Hundreds of thousands of people have to figure out a different costume because a clown plague has infected the country. While I don’t consume tabloid news, I did hear that in some cities, the clowns are getting beat up. I thought, now that isn’t a bad idea, but I wouldn’t advise that. When I was a kid, Halloween antics included dozens of mushy tomatoes and cucumbers left behind in the garden. These have the impact of water balloons, and they make a fine mess. For this post, I referenced my program booklet for ACEEE’s 2016 Summer Study on…

Strategic Energy Management or Strategic Anger Management – Which is Right for You?

By Energy Rant One Comment
I have written about, and formally discussed, strategic energy management (SEM) so much I was sure I already wrote a Rant on the topic. After looking, I wrote about SEM and Yoda, Try Not, Do or Do Not, a year ago, but that was about measures and opportunities. This time, let’s consider SEM programs. SEM Beyond Industrial Strategic energy management is often pigeon-holed as an industrial or manufacturing effort. This is unfortunate and wrong. Strategic energy management is great for commercial and multi-family facilities. Strategic energy management is especially good for MUSH (municipalities, universities, schools, and hospitals) but also office…

Saving Energy, or Not: Mixing Breezes, Ice Blocks, and Toilet Paper

By Energy Rant One Comment
Four years ago, I wrote about a few home energy-saving tips in Refrigerator Sitcoms and Lethal Toaster Ovens. I said I would need to write a series because there are so many, mostly bad, energy saving tips to write about. With four years passing, it is more like a movie sequel than a TV series. Knowing the “why” behind anything helps it stick, like training. Here goes. The Ceiling Fan Famous advice for ceiling fans is to have them move air down (counterclockwise) in summer, and up in winter. A ceiling fan can do two things only. It can generate…

Savings Persistence – Funner than a Barrel of Monkeys

By Energy Rant No Comments
Today, let’s consider a subject that is as squishy, subjective, and amorphous as net savings and non-energy benefits (see here and here). Today’s subject is savings persistence. Savings Persistence and Its Importance Even allowing for generous latitude, if I polled readers of this post, I would probably get a dozen definitions of savings persistence. For retro-commissioning, persistence is ensuring the measures aren’t undone. For the broader group of behavior programs, persistence is getting customers and their occupants (family or employees) to continue to value and manage energy over the long term.To the evaluator, savings persistence opens many cans of worms.…

Learning Calculus via Demand and Energy

By Energy Rant 2 Comments
Last week, I was commenting on some retro-commissioning findings, and I was considering demand savings estimates versus energy savings estimates. A colleague asked, “If you are aware of any energy versus demand papers I would like to know more.” I was informed that the Association of Energy Engineers coursework for becoming a Certified Energy Manager only skims the surface, using a garden hose as a metaphor, for demand and energy. The flow of water represents the flow of power (kilowatts), and the water represents energy – the sum of power over time. This is a disservice because demand charges can…

Thinking Required; Uh Oh – Effective v Triggering DNA

By Energy Rant No Comments
A year ago, I ranted about the Powerwall, part of Elon Musk’s grand vision of flashy widgets. From that post, I will modify a portion to fit this post: Uber is disruptive. Powerwall isn’t. Powerwall is mostly disruptive to the owner’s bank account. It solves no problem, but it does create new ones. In last year’s post, I assessed the cost of electricity storage via the 7 kWh Powerwall. Over the lifetime of the unit, the cost per kWh would be 11.7¢ per kWh, kWh and installation not included. In other words, the storage alone costs 11.7¢. Imagine if your…

Program Adoption Curves – Telephones and Televisions

By Energy Rant No Comments
There are certain energy efficiency programs that we are never going to pursue – all those that are in the late majority and laggard stages. Those ships left the pier 10-15 years ago, and we are not going to attempt to catch them. In two words, they are widget programs, up, down, mid, over, under-stream programs of all stripes, including direct install. The previous chart shows theoretical adoption and market share curves. Of course, in reality, adoption isn’t nearly as pretty, as shown in the next chart, which is fascinating. You will want to get your own version of that…

Burning Behavior Barricades Down

By Energy Rant No Comments
Last week, we briefly introduced an inquisitive concept: what is an incentive for, and who should get it? The rest of the post was consumed with a true story that could be called a merry-go-round of behavior that whipsawed a customer’s energy use over a period of several years. Quantifying Behavior Barricades Every program has some level of behavior nudging. The chart illustrates my first shot for estimating the relative dimensions of behavior barricades that must be overcome for various buckets of programs. The program type requiring the least behavior that I can think of is an upstream incentive program.…

Targeting Incentives – The Retired Farmer in the Mechanical Room with a Crescent Wrench

By Energy Rant One Comment
As we transition out of the dollars-like-dog-biscuits for widgets era into an integrated, connected, behavior and knowledge based era (EE Wave 2), we must reconsider incentives. We must reconsider what incentives are, and who gets them. I am only able to get started on this topic with a specific true story, but first… Sacred Cow #9: EE Programs are not Welfare Programs The status quo dictates that incentives must go to customers paying the electric or natural gas bills. In other words, like a welfare program, dollars must flow from the masses within a population to a smaller group of…

Strategic Energy Management – Try Not, Do or Do Not

By Energy Rant 3 Comments
A couple months ago, I co-authored an AESP Strategies article with Diana Husmann from Nexant and Teri Lutz from Tetra Tech. The subject was non-residential behavior programs. One of the undercurrents that was revealed to me in that process is that strategic energy management, SEM, seems to get pigeonholed as a “behavior program”. First, to digress a bit, every program is a behavior program. ACEEE summarizes these nicely in their Field Guide to Behavior Programs. A super summary of behavior elements are as follows, taken directly from that paper. Cognition programs focus on delivering information to consumers. Categories include general and targeted communication…
