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

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

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
Ann Edminster, M.Arch, LEED AP (pictured left, observing work done in her attic) is a recognized international expert on green-home design and a principal developer of the LEED for Homes rating system. She travels widely and consults with builders, homeowners, developers, design firms, utilities, investors, and public agencies. We recently discussed what’s at the heart of the…Continue
In reviewing the content of Home Energy's January/February issue, I was struck by how rapidly the energy-saving business is changing. In the issue, we cover the come-from-nowhere explosion in LEDs. Another article about energy-efficient homes in Germany describes the rapid shift to near zero energy homes. That article also reminds us why it is getting risky to ignore activities on what used to be the…Continue

You have probably seen those amazing images of the world at night as observed from space—hundreds of times. Below is one photo, but many others show expanded views of smaller areas. I still marvel at how those necklaces of light show the shapes of our cities. The lights tell stories, too. For example, the Korean peninsula appears surgically sliced at the Demilitarized Zone,…Continue
We now know that people learn effectively when they construct their own learning, rather than being told about it. The instructor moves off the stage and becomes the Guide on the Side.…Continue
Home Energy magazine (HEM) has been publishing articles about residential energy efficiency for 30 years. Our articles, editorials, letters, and advertisements provide a kind of window into the evolution of energy conservation technologies, policies, and organizations. Initially, the focus was on audits and simple retrofits, such as weather-stripping and insulation. In those…Continue
The September/October 2014 issue of Home Energy marks the magazine’s 30th year in print. To celebrate that milestone, an industry-wide call for nominations found noteworthy professionals in home performance who were 30 years of age or younger. The feature article introduces the young people who the industry can count on to lead the home performance industry for the next 30 years.
Home Energy’s associate editor, Macie Melendez, compiled the nominations and…Continue
As part of Home Energy’s 30th birthday celebration, we are pleased to reprint a 1994 article by Michael Uniacke describing the way he taught building science in a community college (see the article here). Mastering the intricacies of the building science related to energy performance is no…Continue

Van Jones delivered the opening plenary keynote speech for ACI's 2014 National Home Performance Conference in Detroit last week. I've been aware of Van's work since he started the Green Collar Job Corps program at the Ella Baker Center in Oakland, Calif., back in 2007. Van was the main advocate for the Green Jobs Act that was signed into law by Pres. George W. Bush in that year.
Under the Obama…Continue
Sometimes we forget how complicated a house is. Building scientists know all about a house’s complexity because, even with help from supercomputers, they still can’t reliably simulate many of the processes taking place, let alone model the whole house. Perhaps the biggest challenge is that the darn thing can’t keep still. Cycles with different periods impose their wills on the structure and equipment in not entirely predictable ways. The seasons impose annual cycles for the sun and average…Continue
