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
Lawrence Berkeley National Laboratory is conducting a research study on new homes in California. We invite you to participate in this survey if you live in a:

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.

GAF has introduced training called the Home Energy Saver Certificate - Building Science for the Roofing Professional. It's online, ondemand training narrated by Shane Monday of HUB Energy Group. The professional roofing contractor sees a much larger number of existing homes than many other types of contractors. We're working to connect them with Home Energy Professionals.
You can check out the training we developed and register for free at:…Continue

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
Combustion Safety Testing is one of the most important components of the HEP QCI exam. Because it is linked to the safety of the occupants, it has been a fundamental element of BPI exams since the inception of the organization. As we make homes tighter and more energy efficient, we cut back on the…Continue

A quality control program requires knowing a lot about a lot of different subjects. A HEP (BPI Home Energy Professional) Quality Control Inspector is qualified to compare a project outcome to the project requirements or work scope so that the final result is satisfactory to both the program and the homeowner. It requires both technical knowledge as well as “soft skills” which are…Continue

Houses should last a very long time. The Knap of Howar was built approximately fifty-five hundred years ago. Pueblos in New Mexico were built over a thousand years ago. Saltford Manor House, in Somerset, England was built sometime in the twelfth century and is still occupied! These houses are built of extremely durable materials like stone or adobe. But even the wooden houses…Continue

Hot water distribution efficiency is now included in HERS ratings, under an amendment to ANSI/RESNET Standard 301-2014. This is a Good Thing. To date, all of our efforts to represent, and then…Continue
The old expression when something is supposed to be simple is to say that, “This is not rocket science!” as though rocket science was the most complicated thing we can think of. I will admit that some of the things rocket scientists have done are pretty amazing. I don’t have a clue how you land a probe on an asteroid moving at thousands of miles an hour somewhere out there in space. Or manipulate a vehicle on the surface of a planet and send back, “Wish you were here!” snapshots - in…Continue
In 2014 there were 146,860 homes in the United States that were energy rated by certified RESNET HERS Raters and issued a HERS Index Score. According to the data from the U.S. Census Bureau this represents over 33.8% of all new homes sold in the nation. The average HERS Index Score of the homes rated in 2014 was 63.
The five leading states in terms of homes receiving a HERS Index were:

The Internet of Things has already improved my everyday life. Devices that communicate with each other deliver new services and features that I appreciate. However, as the Internet of Things expands from a few linked devices to a pervasive network, I fear that aggravation will soon replace appreciation. Are we moving toward the Internet of Annoying Things?
We become aware of the Internet of…Continue

Building owners can save money by investing in energy efficiency improvements. But if they can’t afford the upfront costs of the upgrades, they continue to pay higher energy bills and are even less able to pay for energy efficiency improvements down the road.
On-bill financing (OBF) is one tool to help owners break out of this cycle. It provides an opportunity to invest in energy…Continue
