Why Don't Homeowners Spend Money on Energy Saving Upgrades??? Blame "Cognitive Biases"

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…

TV Sets, Homes, and QCI

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. …

Revisiting Electrification

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…

Shades of Gray in Residential Construction Morality

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…

Residential Electric Load Disaggregation

“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.

Renowned…

Programming in-floor electric radiant heat, is it worth it?

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…

Which version of CAZ testing is used for BPI/QCI testing?

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…

150 Years to 10

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…

Rocket Science?

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…

At Home with the Internet of Annoying Things

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…

How to Optimize On-Bill Financing to Help Illinois Building Owners Invest in Energy Efficiency

This post is written by Marcella Bondie Keenan, policy fellow at Elevate Energy.

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…

A Big Boost For Weatherization: Habitat for Humanity on Deck to Help Out

Happy to see that one of our best clean energy advocates, Brad Penney, has rejoined NASCSP as a consultant lobbying for the Weatherization Assistance Program. Weatherization has made a comeback after bottoming out at $68M in FY 2012.  The FY 2015 enacted level is back up to $194M, and the White House has requested $228M in FY 2016. Brad will be leading the advocates fighting to boost Weatherization funding back over $200M and hopefully reach the Administration request in the current…
