Although, or maybe because Michaels Energy has provided research and evaluation services for about 25 years, I’ve been a consistent critic of evaluation, measurement, and verification (EMV), and I’ll tell you why in several chapters. Chapter 1 Resource Acquisition Evaluation methodologies are predominately based on widget programs, also known as resource acquisition programs. The hypothesis is this: efficient equipment costs more, and that extra cost is the barrier. How to mitigate or remove the barrier? Pay down the incremental cost with a rebate after the purchase or incentive before the purchase. It’s that simple and dumb. The simpleton approach to…

I've been doing a lot of program impact evaluation for the last few months. That comes with pluses and minuses. One of the minuses is that I needed to suspend writing this blog for a while. Pluses include problem-solving, working with staff throughout our company, and forensics engineering. Impact Evaluation But first, what is impact evaluation? I have a broad audience, and I get great feedback, some of which is, "I don't know what you're talking about sometimes." Entities delivering efficiency programs (implementers) are responsible for delivering savings or impacts. For custom efficiency portfolios, which entail a wide variety of…

Hi. How’re you? Jeff Ihnen here. I’m back and almost live. I’ve been away on several temporary assignments that are starting to wind down. We are thrusting forth into the 11th year of the Energy Rant! Indispensable Thumbs Unless you have broken one, lost one, or had one immobilized, you probably have no idea of the value of your thumb and its equivalent, the big toe. I’m sitting on an airplane as I bang this out, munching a bag of almonds. Thumb and a finger. Thumb and a finger? That’s how you and I and anyone with a fully functioning…

If efficiency programs were telephones, the evaluation community would still be using wall-mounted analog dial-ups rather than the iPhone. Yes, I’m going to tell you why programs are designed to be evaluated and not to be effective, part 2, herein. The following is the list of flaws in demand-side management theory, as presented last week. Efficiency must cost more than inefficiency Building energy codes are sacrosanct Efficiency has to be the primary factor in customer decision making Customers must “get their money back” The unfamiliar get fifty cents on the dollar Immortality is fantasy Last week we covered the first…

Thank you to Mike Frischmann (our Director of Evaluation Engineering) for contributing to this week’s Rant. Eight hundred pound gorilla alert! Energy efficiency program evaluation “best practices” need a big overhaul. I am not talking about best practices for doing impact evaluation like the Uniform Methods Project. It’s disgusting that so much money is spent on standards like that and others, while ulterior motives drive program evaluation in entirely different directions. Purpose of Program Evaluation The State and Local Energy Efficiency Action Network, aka SEE Action’s Energy Efficiency Program Impact Evaluation Guide, states the following are objectives of program evaluation.…

Evaluation, Measurement and Verification 2.0, or EM&V 2.0, is a nerdy term coined in 2014, according to this blog by Northeast Energy Efficiency Partnerships (NEEP). The hype of EM&V 2.0, which I will explain later, is that it will automate measurement and verification, putting us engineers out of business. This is not going to happen anytime soon. Definition 2.0 The definition of EM&V 2.0 boils down to using utility meter interval data, typically hourly or sometimes every 15 minutes, or maybe even 5 minutes, to disaggregate and measure impacts from energy efficiency measures. One could consider that EM&V 2.0 is…

It has been a while since I’ve written anything about programs, so here it goes. Program evaluation provides about half our business, and much of that is verifying gross savings estimates, which are simply the original program-claimed savings. Verifying custom projects, those that don’t fall into mass categories like light bulbs and air conditioners, are generally more interesting, at least from an energy analysis perspective. Findings from the field can be follical (new word derived from folly) for any type of measure. Implementers of custom efficiency programs, especially implementers not accustomed to the evaluation process, can be especially entertaining. In…
