Those of us working within the building industry or energy efficiency space in existing homes know that boosting insulation levels can reduce energy use, cut consumer costs and greenhouse gas emissions. Yet, there’s been a modest amount of data to quantify the extent of the benefits—particularly at the state level. Until now.

Every time I visit Japan I learn something new, and my most recent trip was no exception. This time I stayed in an apartment, which exposed me to several new energy-related devices. First, what’s this gadget attached to the wall? (See photo below.)
Reading the Japanese isn’t terribly informative, because the label just says it’s a “peak alarm unit.” The apartment’s owner pays the…Continue
It turns out that one of the most valuable remodeling options is one you can’t see. That’s the conclusion of the recent Cost vs. Value Report by Remodeling magazine, which compares the average cost for popular remodeling projects with the value those projects retain at resale value in 100 different U.S. markets.

Fitness wearables inspire people to change; to exercise more in order to meet their daily goals. These sophisticated gadgets gather previously untapped data about our everyday lives to give us a better understanding of ourselves – otherwise known as the “quantified self.”
Like fitness wearables, exposing how we’re using energy can unlock our collective potential to reduce our electricity bills and our…Continue
A curious situation has recently arisen in electricity grids around the world: The wholesale price of electricity has occasionally gone negative. This means that the market will pay customers to use electricity. The grid in Texas experienced negative prices last September. Soon afterward, a Texan retail electricity provider—not to be confused with a utility—began offering residential…Continue

You would be professionally remiss if you did not read “Attics and Crawl Spaces” in this issue. The article by Terry Nordbye is a valuable reminder that home performance problems too often begin in the places that we least want to work on or inspect. Mold, dry rot, and despicable smells emanating…Continue

The idea of business transparency might seem antithetical to success and may frighten some companies. But collaborative efforts across businesses and sectors have shown that the triple-bottom-line benefits of transparency far outweigh the perceived risks. In fact, as more consumers demand proof that the products they buy fulfill the promise of the label, transparency is becoming a key differentiator that sets…Continue
Last year I moved into a house that needed some work. So far I’ve replaced the foundation, installed seismic upgrades, added central heat, repainted, and much more. (Anybody know a good fireplace guy?)
Along the way, I’ve been slowly upgrading to smart home technology. I ripped out my old, broken doorbell and added Ring, which detects when people are at my door and sends a video notification to my phone.…Continue
It is not often clear the path a BPI-certified energy auditor should take, or where exactly the opportunities lie… to buffer existing business, as side work, to work as a full-time energy auditor, or to go out on your own, the opportunities are vast and diverse. Oftentimes we get our energy auditor certification as a kind of back-up plan or to aid a struggling business. Or maybe you attended BPI training as…Continue

The outrage against Volkswagen (VW) is justified, but let’s not forget that other manufacturers—a lot of manufacturers—have been circumventing energy and emissions tests for decades. Here are a few of my own experiences.
Cadillac was circumventing emissions test procedures 20 years before VW. Cadillac’s engineers faced the same dilemma: How do they comply with emissions control requirements without sacrificing performance? Not surprisingly, they solved…Continue

After the first oil embargo, in 1973, our nation recognized the need to save energy in a coordinated way. It made sense to designate energy utilities to coordinate energy-saving activities in buildings, because nobody had better access to the customer and to key information about the customer. This led to three decades of utility-managed energy conservation programs. Many succeeded. Some did not.
But times change. Today, there’s a new imperative:…Continue
