Passive Homes: The Way of the Future

The Passive House standard is the fastest growing building standard in the world. It is still in its infancy in the United States, but has taken off in countries like Germany, where it is known as Passivehaus. There are over 30,000 certified Passive ...
Owners of older homes often contact GBAGreenBuildingAdvisor.com and ask, “What can I do to make my home more energy-efficient?” My standard answer goes something like this: “The first step is to hire a certified rater to perform an energy auditEnergy audit that also includes inspections and tests to assess moisture flow, combustion safety, thermal comfort, indoor air quality, and durability. of your home. The audit report will include a tailor-made list of retrofit measures to address your home’s specific problems.”

In finding ways to "build it green", the architect also discovered that this philosophy is very much in keeping with the well-accepted practices in Mexico of reuse and repurposing. In the main house, there is a living room, kitchen, office, bedroom and ...
We’ve been keeping an eye on the sweeping Energy Savings and Industrial Competitiveness Act (PDF), introduced by Senators Jeanne Shaheen (D–NH) and Rob Portman (R–Ohio).
The common-sense bill, likely to come to the Senate floor any day now, enjoys broad support across the political spectrum. It would boost the national model energy code for both homes and commercial buildings, support commercial retrofits with financing help, and develop training programs for green building jobs.

Readers of this Energy Solutions blog may be aware that I’ve been critical of some of our foam-plastic insulation materials. I’ve come down hardest on extruded polystyrene (XPS), which is made both with a blowing agent that contributes significantly to global warming and with a brominated flame retardant, HBCD, that’s slated for international phaseout as a persistent organic pollutant.
So I’m always keeping an eye out for alternatives. I’ve written here about two of those alternatives that I’ve used in our own home: a cellular glass material called Foamglas with high compressive strength that works very well below-grade; and Thermacork, an all-natural rigid insulation material made from expanded cork.
I like both of those materials a lot, but they have two big problems: high cost and limited availability. They just won’t be able to enter the mainstream home building industry—not yet, anyway—since they cost more than twice as much as XPS and polyisocyanurate and are hard to get hold of.
Do you want a good air barrierBuilding assembly components that work as a system to restrict air flow through the building envelope. Air barriers may or may not act as a vapor barrier. The air barrier can be on the exterior, the interior of the assembly, or both. on your house? Of course you do. No one who knows anything at all about building science believes that old myth that a house needs to breathe. We want airtight houses, but then we want mechanical ventilation to bring in fresh air from outside (well, at least as fresh as you can get from your outside).

Turning waste into a unique architectural product, Coldspring and Jason F. McLennan have teamed up on a new dimensional stone product.
As the founder and CEO of the International Living Future Institute and its influential Living Building Challenge, Declare product database, and Living Future unConference, Jason F. McLennan has been busy setting a high bar for “green.” Now the former BNIM architect has crossed over into product design, as he is set to announce tomorrow the launch of a unique line of sustainable dimension stone products called Earth Measure, in a collaboration with Coldspring, one of the nation’s largest natural stone providers.
In a world in which green products are defined by recycled content and low VOCs, natural stone has arguably gotten short shrift, as we noted recently in Environmental Building News, in Stone, The Original Green Building Material. Stone is simply cut from the earth and processed., It emits no VOCs or hazardous airborne pollutants, it is water-resistant, will outlive most buildings, and can be reused after the structure is no longer usable. How can you build on that pedigree?
How about turning the relatively small amount of quarry waste produced by stone manufacturers into a valuable product? While working with Coldspring as a consultant, McLennan recognized that the offcuts from stone processing still had value beyond landscaping and aggregate, and with Cold Spring’s corporate goal of creating zero waste from processing, a partnership was born.
After years of living with a nice-looking but rather uncomfortable daybed in our living room, my family and I went shopping for a new sofa. We explored a range of styles and configurations, trying to find something that looked good, would be cozy, durable, and fit in our rather small space. Oh, and we also wanted to avoid bringing toxic and ineffective flame retardant chemicals into our home.

For years, the English-language website of the Passivhaus Institut in Germany provided this definition: “A passive houseA residential building construction standard requiring very low levels of air leakage, very high levels of insulation, and windows with a very low U-factor. Developed in the early 1990s by Bo Adamson and Wolfgang Feist, the standard is now promoted by the Passivhaus Institut in Darmstadt, Germany. To meet the standard, a home must have an infiltration rate no greater than 0.60 AC/H @ 50 pascals, a maximum annual heating energy use of 15 kWh per square meter (4,755 Btu per square foot), a maximum annual cooling energy use of 15 kWh per square meter (1.39 kWh per square foot), and maximum source energy use for all purposes of 120 kWh per square meter (11.1 kWh per square foot). The standard recommends, but does not require, a maximum design heating load of 10 W per square meter and windows with a maximum U-factor of 0.14. The Passivhaus standard was developed for buildings in central and northern Europe; efforts are underway to clarify the best techniques to achieve the standard for buildings in hot climates. is a building in which a comfortable interior climate can be maintained without active heating and cooling systems. The house heats and cools itself, hence ‘passive.’”

Wait a second. Spring has barely sprung, and you’re saying we need to start thinking about energy audits already? What’s up with that?
There are several reasons why now is a good time not only to focus on energy auditing and weatherization—not only for your clients, but also for your own home.
Weatherization professionals have some time
Because spring is a time when few homeowners are thinking about heating bills and how to bring them down, it’s a good time to find energy-performance contractors who can do that weatherization work.
Those energy-performance contractors who do general construction work may be gearing up for the summer building season, but for those limited to energy audits and weatherization, now is a good time.
Amy Musser has a PhD in Architectural Engineering and, like me, used to be a college professor. Her husband, Matthew Vande, is an architect with an MS in Architectural Engineering. He is also a treehugger (see the black and white photo below). Together, they founded Vandemusser Design, a firm that provides green design, certification, and consulting.

It’s been a long and confusing year for people who track federal green building policies.
Between the military’s LEED battle and the loooong interagency review by the U.S. General Services Administration (GSA)—both of which are sure to be complicated by sequester and politics in ways we don’t yet understand—we’ve had newsroom motion sickness for months.
A Friday press release from the U.S. Green Building Council (USGBC), republished in Building Design + Construction and covered by Lloyd Alter at Treehugger, unfortunately hasn’t brought clarity to the conversation.
