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...

Utility Relationships and Hookup Puns

By Energy Rant No Comments
I attended Peak Load Management Alliance’s 45th Conference in Baltimore last week, where I captured a quote that went something like this: the difference between energy efficiency and demand response is that demand response is a relationship between utility and customer. In contrast, efficiency is a transaction or two followed by the customer and utility parting ways. I thought, hmm, so it’s like renting an apartment versus a hotel for a night or two – or a long-term relationship where two people actually know each other’s names versus a hookup. Ok. Hookups Most of us reading this cannot relate to...

Socially Undesirable Net Savings

By Energy Rant No Comments
I’ve never been a parent to humans, but as I say to friends and companions, I was a child once, and I did have parents. Moreover, I’ve supervised and had dozens of people report up to me directly or indirectly. Plus, I love kid stories, so I may be more uh, qualified or knowledgeable than some prospective thirty-year-olds who are about to take the plunge. Sleep up, my friends! Similarly, I have many roles in the utility-led efficiency business, conceptualizing, developing, delivering, and evaluating efficiency programs. I’m an engineer and not a social scientist but see above with the parent...

Soaked to Crisp Threats and 100% Renewable Energy

By Energy Rant No Comments
Last week I attended the International Energy Program Evaluation Conference, IEPEC, which I had affectionately dubbed the Energy Program Evaluation Asylum, EPEA, six years ago. Back then, I called it the Asylum because it included annual scrums over subjects such as net-to-gross (NTG) studies, free ridership, and so on. The Family Feud is Dead You’ll never believe this, but the industry seems to have moved on. The only time I heard “NTG” was during the opening-night entertainment exercise – a gameshow wannabee modeled after the Family Feud. “One hundred evaluators were surveyed. The top six answers are on the board....

Net to Eeeew, Gross – Pin the Tail on the Donkey

By Energy Rant One Comment
Anytime I listen to a net-to-gross (NTG) scrum, the philosophical gears in my brain ramp up to a smooth whir. This is what happened at ACEEE summer camp, also known as the ACEEE Summer Study on Energy Efficiency in Buildings. This post is inspired by a paper titled “Applying Gross Savings and Net Savings in an Integrated Policy Framework”, presented by Dan Violette (Navigant) and co-authored by Elizabeth Titus (Northeast Energy Efficiency Partnerships), Pam Rathbun (Tetra Tech), and our very own Teri Lutz. Since Dan referenced the SEE Action Energy Efficiency Program Impact Evaluation Guide, for purposes of saying the...

Attribution and Net to Gross – Pop Tarts or Oatmeal?

By Energy Efficiency, Energy Rant 4 Comments
Last week I attended the ACEEE National Symposium on Market Transformation in Baltimore.  Learning and information gathering from conference sessions are typically down the list of reasons I attend conferences.  This conference however turned out to be very beneficial on both of those counts.  In particular, the net-to-gross (NTG) football, as described in last August’s Energy Program Evaluation Asylum post, was uncased for another game.  This time I learned something[1]. One session featured heavy doses of program attribution, and of course, the NTG football.  Speakers included Bob Wirtshafter from Wirtshafter Associates and Mike Messenger from Itron.  Both gentlemen demonstrated the...
