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.

Great enthusiasm for home energy efficiency is often matched with misconceptions. Let’s explore a bit and figure out the difference between what we perceive, believe, and what we know to be true.
Windows: We see through them every day and curse the drafts coming through and around them. We are certain that old windows are the main culprit behind why we spend so much…Continue
Comparison Between LP Gas Range and Induction Burner
Admittedly, this is a simple and very limited analysis, but it does offer some useful information. I wrote about induction cooking 2 years ago, the cost has since come down enough that I recently bought a single coil, counter-top unit, and after a week of use, the numbers are in.
BUILDER Magazine recently published “Five Alternative Construction Methods,” a series of articles looking at “building methods that are gaining traction because they save time, money, and headaches — or all of the above — while producing better results and more energy savings.”
The story titled “…Continue
What is Drain Water Heat Recovery?
Answer this...when you take a hot shower, what happens once that HOT water goes down the drain and how do I reuse the energy? That is Drain Water Heat Recovery!
A "DWHR" can capture waste heat energy and be used to heat NEW incoming water, saving money & energy, as well as the life of your hot water tank. It also works well with Geothermal, Solar and Tankless (on demand) Water Heaters.
In residential and commercial applications, all the…
We did a study for CMHC back in the early 00's looking for great examples for a series of case studies that required collecting a ton of info on many projects. CMHC published only 3 of 24 case studies, but…Continue

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
Affordable apartment buildings are home to more than 10 million American households, making them a backbone of U.S. housing stock. They also waste a lot of energy.
In fact, energy efficiency measures are far less likely to be found in multifamily buildings than any other type of housing, according to a 2011 report by the U.S. Department of Housing and Urban Development.
Several hurdles have stalled upgrades: building owners lack access to capital, utility-run efficiency…Continue

Each year, Habitat X engages in a search for up-and-coming young professionals in the home performance industry. We take applications from individuals who are less than 40 years old, and we ask them to iterate a focused vision of an industry future that we think is far-reaching but plausible. We then choose one person from among these applicants who is poised to make important…Continue
A 15 year-old affordable housing development in downtown Ionia, Michigan won the 2015 Michigan Battle of the Buildings energy saving competition for apartments. Building upgrades and subsequent systems optimization to the 39-unit complex were completed in April 2015. Through March 2016, these upgrades have cut gas…Continue

Rainwater harvesting is a system which requires a two-step process. The two major events in rainwater harvesting are catchment and storage. The first hurdle is developing an adequate method of collection. Once the rain is collected, a proper and large storage system is required. The complexity and size can vary dramatically. The simplest methods involve the rerouting of gutters into an above ground rain barrel up to a complex system of catchment dishes, filters, pumps, ponds and…Continue

RESNET convened its Building Performance Conference in Scottsdale this March, a hospitable time of year in the Arizona desert. I roamed the sessions, and a few of the bars, to keep abreast of developments in home energy rating and performance.
2016 PRIORITIES: IMPROVING QUALITY AND LOWERING COSTS OF HOME BUILDING
The many young attendees wearing new company jerseys at this year’s conference were a sign that the energy-rating business, at least for new homes,…Continue
