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

When we built our new home 50 miles from Austin on 21+ acres we made the decision to have all of our indoor water come from harvested rainwater and to make our flower gardens bigger than they were at our first country…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

Macie Melendez: How did you get started in the home performance industry?
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
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

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
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
