There has been much ado about the recent paper published by E2e; Do Energy Efficiency Investments Deliver? Evidence from the Weatherization Assistance Program, the final word on which is yet to be written.
Decades of experience and verification prove energy efficiency programs deliver huge benefits to consumers and the environment - and these benefits far exceed the costs. But numbers can be distorted and therein is the bane of Energy efficiency projects.
E2e has some heavy…Continue
laser measure devices are quickly replacing the traditional metal tapes due to their effectiveness and accuracy. While the simplest use of this kind of artifacts is measuring the distance between two points, there is a wide variety of extra applications you can find for your laser measurer.
Below you’ll find a large list of additional applications for your laser measurer.
Large storage facilities equipped with…Continue

Matthew Wadlund is adding infill housing stock to the Oceanview neighborhood of Berkeley, California, where he is replacing a single-family house with four single-family, three-story detached houses. The wall panels in Matthew's Oceanview Orchard homes are constructed off-site and craned into place, resulting in maximum material efficiency and near-zero waste. Tom White, Home Energy's publisher, spoke with Matthew about his decision to prefabricate wall panels…Continue
By now you are probably aware of California’s drought. But other states are experiencing droughts—and where there aren’t droughts, there are probably floods. Water and energy consumption are becoming more and more closely connected, and the situation is not likely to improve. Here are some of the ways our clients experience these connections in their homes.…Continue

Most of the recent trade press seems focused on tankless water heaters. Whether used in whole-home or point-of-use configurations, tankless water heaters solve some of the efficiency problems associated with storage tank heaters. While these systems are worthy of discussion,…Continue

As you read this blog post, what room are you in? How’s the lighting? How’s the temperature? Do you control their levels — or is someone else, somewhere else, running the show?
About 40% of energy use in the U.S. is consumed in…
For those not familiar with “Ching books”, they’re essentially the gold standard for visual architecture reference and aid in the design process. Architect Francis D.K. Ching’s series of textbook-size volumes go through conceptual to intimate detail of design and construction for both novice and professionals alike. They’re commonly noted as the best and easiest-to-understand references for design…Continue

The poet Muriel Rukeyser once said something like this: The Universe is not made of atoms; it’s made of stories. I think that conferences are made of stories too, like the one I’m at this week, the National Energy and Utility…
When I received an email from Larry Zarker of BPI, informing me that I had been inducted into the BPI Building Performance Hall of Fame, I thought it must be a big mistake. Then I looked at the list of previous inductees and was sure it was a mistake! I haven’t even done a blower door test all by…Continue

A great transcript from a recent NPR "Morning Edition" broadcast about a recent California survey on water conservation efforts. The results are exactly what we find with energy conservation... When homeowners were asked what actions will save water, most said "taking shorter showers" (turning down the heat), or "keeping water off while brushing" (wearing a sweater) which of course is a complete mismatch of real saving efforts, like installing low-flow toilets (installing insulation).- which…Continue
I have had the pleasure of talking to a lot of wonderful people about the challenges of the BPI QCI Certific ation, and I am getting some unique insight. I started out working on my book – Residential QCI Handbook on a quest to help candidates who are preparing to take the exam. …Continue

I must admit that I am still having trouble getting my head around this idea. But the arithmetic is fairly simple: an 80% reduction in carbon emissions simply can’t be achieved without drastic cutbacks in residential natural gas use. In the residential sector, natural gas burned on site is responsible for about one quarter of carbon emissions. We can use carbon-free electricity generated…Continue
I was called in to perform a last minute duct test for a modular home builder. He was all in a dither to have a duct test and a blower door test done on a Friday so that he could get his Certificate of Occupancy (CO) so the homeowner could move in the following Monday. He said that he’d just found out that he needed these tests. The building inspector asked for them at the last minute!
I was glad to do it partially because it’s good to have builders aware of what is going on…Continue
“What gets measured gets managed” is a quote often attributed to the venerable management expert Peter Drucker. The simple but powerful idea behind the statement is that without quantitative measurement, it is impossible to benchmark the current state and manage progress toward a desired state. Variations of the quote abound but it is difficult to trace the quote to a specific book, paper, or speech. As it turns out, an earlier incarnation of this idea predates Drucker.

Does a programmable thermostat for an in-floor electric radiant heat system add efficiency, or is it faux efficiency?
My electrician installed in-floor electric heat in a second floor bathroom remodel I recently completed, and he used a non-programmable therm. I asked him to change it, and he pushed back that there is little efficiency gain because the thermal mass of the mud bed and tile create a long cycle time to raise the temperature. Better to leave the temperature set, and have…Continue
