Why PHIUS? To Be Part of the Solution

Some inspirations from the Seattle conference to kick off 2018

At PHIUS, we’ve been at this passive building business for a good long while. And we’ve been inspired to see so, so many professionals join and build our community. Every year we’re all so busy that it’s pretty hard to find the time to just talk about why we’re all doing what we do. That’s why each conference is such a blast.

To capture a little of that fun–and inspiration–we asked a question of some attendees at the 2017 North American Passive House Conference in Seattle, Washington. The question:

Why do you build to PHIUS standards?

Here are some answers and comments we received–we hope you can relate to one or more of them, and please feel free to chip in your own answers in the comments section.

Elizabeth Correa, LMN Architects, Seattle: I design to PHIUS standards because it was a standard that allowed me to align my principles, my design principles, and ethical principles.

 

Sam Rodell, Rodell.Design, Spokane, Washinton: Building to the PHIUS standard is, I would say, our practice considers that to be our baseline and I think that anyone who builds today and does not consider the possibilities of what is happening here with building science wanders around in a dangerous territory of what I would consider to be professional negligence.

 

Lindsay Schack, Love | Schack Architecture, Bozeman, Montana/ Driggs, Idaho: I found PHIUS when I was researching affordable and high-performance wall assemblies for a client of mine. And once I found out about PHIUS, I went down this rabbit hole of learning building science, and now I can’t go back. I can’t, with good conscience, build to code anymore. I have to push farther.

 

Doug Farr, Farr Associates, Chicago, Illinois: Our practice is devoted to sustainability. We’re architects and we are striving to achieve PHIUS+ on a couple of projects, one is a new build and one is a rehabilitation. It’s challenging and frankly, that’s why I like it.

Schack: PHIUS, the institute, not only provides you with support and knowledge, it provides you with camaraderie, and I’ve learned from great professionals, and it has pushed my projects to a level that is gaining notice in my industry and where I live.

Correa: And that marriage between building science and architecture through PHIUS has made me passionate about architecture again and passionate about our mission to address the problems of climate change.

Farr: Some of the other systems which are also worthy and ambitious also are hard to do, but they all have what Kat always calls a ‘get out of jail free card,’ which is that you can always compensate for building a less efficient building by adding more PV or renewable energy.

Correa: And I realize that buildings being a large percentage of the carbon emissions problem and I don’t wanna be part of the problem. That is why PHIUS is especially important to me.

Farr: Passive House is the gold standard.

Correa: I’m part of the solution and I’m not any longer part of the problem.

Why PHIUS? Because Climate Specific Design = Quality Assurance

Why do you build to PHIUS Standards?

Asked at the 2017 North American Passive House Conference in Seattle, WA.

Lindsey Elton, ECO Achievers:  …E-L-T-O-N like Elton John…

I believe in PHIUS because the organization has taken an extremely detailed look according to our climate zone of what it takes to build a net-zero home or a net-zero building.

Peter Marciano, Legacy Buildings, New York, NY: I’ve come to the conclusion based on what I’ve built that there’s a lot of information out here. There are several passive house programs available. And, for me, having come to the realization that it has to be climate-specific because that’s what works. That’s what works in this nation. That’s what works in this country.

Marc Rosenbaum, EnergySmiths, West Tisbury, MA: I’ve been doing this for almost 40 years, and one of the things that PHIUS brings to the table here that are so amazing to me is people are interested in the actual performance of the buildings. They’re measuring them. They’re comparing them to what they thought they should do, and it’s a really terrific community that is sharing the information to make better buildings.

Elton: They’ve taken all the guesswork out, they’re doing the calculations, and they were smart about it. And we can employ this time after time after time again.

Marciano: If it’s not climate specific, I have had definite problems with certain aspects of my enclosure and certain aspects of my building. And I wouldn’t make that mistake again. I would definitely use a climate specific standard to establish… To build my next passive house.

Rosenbaum: And I think we all know why we’re doing it. We’re doing it because we care about the climate, we care about the kids, we care about other species besides ourselves. And we don’t talk about that. We talk about BTUs, and thermal bridges, and solar heat gain coefficients.

Elton: We’re firmly behind it, our company’s firmly behind it. We believe in it, and that’s why we’re here.

Rosenbaum: PHIUS has really created this community of people, who I think, care about each other’s learning, and share our successes and our failures, and it makes all of us better.

Why PHIUS+? Science, Climate, Energy Modeling

 

Why do you build to PHIUS Standards?

Asked at the 2017 North American Passive House Conference in Seattle, WA.

“As opposed to building standard code buildings?”
—Nichole Schuster, Ashley McGraw (Syracuse, NY)

“The question really is, how do we respond to climate change in the buildings that we build?”
—James Geppner, Big Yellow Cab (Cold Spring, NY)

Schuster: “I design to PHIUS+ standards because it’s an intensely rigorous energy efficiency standard.

Geppner: “And if we’re gonna respond, then, we need something that’s science-based and we need something that’s performance-based.

It doesn’t just have one component or another, but it actually performs to a certain level. And that that performance is measurable.”

“My passion is using the best technology and the best in building science to model energy use in buildings and to improve building efficiency.”
—Maren Longhurst, Rodell Design (Spokane, Washington)

Geppner: “It’s one way to achieve basically, a building that requires very little energy and does so and produces a high indoor quality.”

Schuster: “I think it provides greater levels of resiliency. I think it’s tailored to our specific climates that we get the maximum benefit out of it, and it can also help us achieve other standards and goals like the Living Building Challenge, Energy Petal, for example.”

Geppner: “Part of what makes it the best is that it uses what I think of, or what I call the dynamic energy model.

Longhurst: “PHIUS provides software Wi-Fi Passive and Wi-Fi Plus that really get deep into the details of a project.”

Geppner: “The information that goes into designing a building is information from that region. It’s weather data, it’s climate data, so that when you have a house, it’s not thoughtlessly constructed, it’s constructed to the temperature of that region, the moisture of that region.”

Longhurst: “And allow us to predict what a project will do and help us to design that project to be the most efficient, and the most comfortable, and the best quality building.

Geppner: “An option to get away from a construction method—which there’s basically no technology, it’s kind of a 400-year old process—to something that’s more like the thinking and the modeling that goes behind constructing something like an iPhone, or a high technology product, and it works.”

10th Annual NAPHC – best party of the year, maybe ever…

Wow – was that a successful conference! It has been a week and I am still processing it all. Chicago was unlike any other conference — things did not slow down in the office after it was all over, they rather accelerated. It indeed appears we have reached a tipping point.

From more than one person I heard that it seemed that the quality of work, detailing expertise and technical knowledge, size of projects and complexity of building types had reached a new high. And, compared to the early years, we were not just talking theory and intentions—but what people had done! Really impressive.

New modeling tools such as WUFI Passive (Technical keynote Hartwig Künzel, day two) are making building science interrelationships more visible and intuitively understandable. WUFI Passive is enabling CPHCs to optimize designs using “hygrothermal mass” (ever heard of that?) to optimize humidity loads and even to inform design decisions overall (as Sebastian Moreno-Vacca illustrated in his session) to create a unique architectural language! How cool is that! Science, heat fluxes and thermal dynamics begin to shape architectural form.

Dirk Lohan, Principal, Lohan Anderson -- Welcomes conference attendees to Chicago

Dirk Lohan—Mies Vander Rohe’s grandson, and an extremely accomplished architect in his own right—hinted at this development during his welcoming remarks.

“I believe that we will begin to see as beautiful what also is energy-conscious,” said Lohan.

Supported by the John D. and Catherine T. MacArthur Foundation

But maybe the most significant news is the explosive development in the multifamily affordable housing sector. It is seeing significant growth, interest and pilot developments going up in many places of the country. Thanks to the support from the John D. and Catherine T. MacArthur Foundation, we were able to make this our core topic for the conference and will be able to actively provide support to the affordable development community.

The pre-conference sessions included a daylong affordable housing Hootenanny that brought together successful affordable, multifamily housing project teams together who generously shared lessons learned and experience. Four different project teams presented during an intense full day. The morning and afternoon presentations drew full rooms of affordable housing developers who soaked up the information and had terrific, incisive questions

The same teams presented again during the core conference breakouts in a more condensed form for those who were unable to attend the hootenanny. In addition, there were more presentations on even bigger size affordable projects in progress:

  • A 101 unit affordable development in New York now under construction in the Rockaways (Steve Bluestone, Bluestone Org.)
  • A planned affordable retrofit of a 24 story historical brick building in Chicago (Doug Farr, Tony Holub from Farr and Assoc.), the Lawson House.
  • 24 story residence hall under construction in NYC (Matt Herman, BuroHappold)

Really amazing stuff.

Katherine Swenson

Katherine Swenson, Vice President, National Design Initiatives for Enterprise Community Partners — Day 1 Opening Keynote

Of course this growth has been fueled by forward-looking programs that recognize that energy efficient homes make so much sense for affordable housing developers/owners and dwellers. Katie Swenson from the Enterprise Foundation was a breath of fresh air–dynamic, positive, and motivating opening keynote. She explained that in her and her organization’s eyes energy is a critical part in assuring not just housing for people—but healthy housing! “Health is the new green,” she said, and of course passive housing delivers here with excellent comfort, indoor air quality and the added bonus of resiliency when the power goes out. Katie announced that the Green Communities criteria had just included PHIUS+ 2015 certification as one of the highest energy point options.

Other affordable housing agencies also have made a move: the Pennsylvania Housing Finance Agency (PHFA) awarded bonus points in its last round of selecting projects for Low Income Housing Tax Credits. More recently the New York State Homes & Community Renewal (HCR) effort was mentioned in a release regarding energy efficiency measures from the White House. Those agencies now directly encourage passive building standards in their RFPs. Remarkable!

Sam Rashkin, U.S. D.O.E. -- Closing Plenary Keynote

Sam Rashkin, U.S. D.O.E. — Closing Plenary Keynote

On the other coast. Seattle just amended their multifamily building code to allow additional floor area ration (FAR) for projects that meet the PHIUS+ 2015 criteria. That’s a significant incentive for developers.

Things are cookin’!

The core conference, as usual, was chock full of goodness. There were examples of how the new PHIUS+ 2015 climate specific passive building standards helped to optimize costs both here in North America (presentations by Chicago’s Tom Bassett-Dilley, Dan Whitmore, and) and internationally (Günther Gantolier from Italy). There were nuts-and-bolts presentations on wall assembly solutions (Tom Bassett-Dilley again), air and water barrier best practices (Marcus and Keith). And, the Builders Hootenanny—led by Hammer & Hand’s Sam Hagerman, focused on component challenges such as sourcing airtight FDA approved doors for commercial construction.

The U.S. DOE’s Sam Rashkin closed the conference with an unexpected message: he suggested that we needed to rename a few things to facilitate behavioral change. He posited that ZERH, LEED, PHIUS and other green building programs are essentially fossil fuel use rehab centers trying to rehabilitate an addicted nation and to show how it can be done differently. He received a standing ovation.

A few more comments on pre-conference workshops – three WUFI Passive classes drew almost 80 people and they all were super happy throughout the two days! Who would have thought! Happy people energy modeling!

Marc Rosenbaum single-handedly won first place in registering the most people for his class to connect passive principles with renewables to get to positive energy buildings (the logical next step).

Joe Lstiburek placed a close second (sorry Joe) and did a phenomenal job in covering ventilation concerns in large multifamily buildings. Rachel Wagner showed the most awesome cold climate details that I have ever seen. Galen Staengl took folks on a spin to design multifamily and commercial mechanical systems.

And Gary Klein topped it all off by reminding us that without efficient hot water systems design in multifamily, no cigar!

Thanks to all presenters and keynotes! You made this an excellent and memorable event.

I have not even mentioned the first North American Passive Building Project Awards—the entries were just beautiful projects—check out the winners here. I must mention the overall Best Project winner of 2015, as I believe this is pivotal: Orchards at Orenco. What a beautiful project, the largest fully certified PHIUS+ project in the country to date, a game-changer, underlining affordable multifamily projects on the rise.

I’m extremely happy that the Best Projects winners for young CPHC/architects was a tie, and both winners are women! Congrats to Barbara Gehrung and Tessa Smith! Go girls, you are the next generation of leaders!

L-R: Best Overall Project: Orchards at Orenco; Best Project by CPHC under 35 (tie): Island Passive House, Tessa Smith; Best Project by CPHC under 35 (tie): ECOMod South, Barbara Gehrung

L-R: Best Overall Project: Orchards at Orenco; Best Project by CPHC under 35 (tie): Island Passive House, Tessa Smith; Best Project by CPHC under 35 (tie): ECOMod South, Barbara Gehrung

One last note on a thing: Passive building people know how to party while devouring the most challenging, inspiring energy science, details, philosophies (Jevons paradox – Zack Semke’s fascinating lunch keynote) from the field.

And the architectural boat tour on Saturday to top it all off was almost surreal. When we were all out on Lake Michigan and the fireworks went off over the magnificent skyline, I thought, “that’s how we roll :).” Plus, the docent from the Chicago Architecture Foundation was a font of information, and even long-time Chicagoans learned a lot along the way. If you weren’t there, you missed the best passive building party of the year, maybe ever. (But we’ll try to top it, promise.)

Finally, for the crew that just can’t get enough, the Passive Projects Tour on Sunday was, as always, an enormous hit. Tom Bassett-Dilley and Brandon Weiss put together an array of completed and in-progress projects that generated a buzz at every stop. Thanks to Tom and Brandon and to PHA-Chicago for all your help!

Cheers!

From passive house to passive buildings–what’s new and how manufacturers are stepping it up

BE15banner-LARGE

Exciting times indeed for passive building in the United States: Passive design principles that originated here and in Canada are all grown up and making a furious comeback. Policy makers, researchers and scientists, builders and designers are all embracing passive building in their everyday practice.

And as always, the growth is evident here at NESEA’s annual high-performance tour de force: NESEA BE15. A quick recap: Passive Building Place–a concentration of passive building component exhibitors, and the tour of their offerings, is in its fourth consecutive year. For those who remember, we started my first blog on the NESEA trade show focusing on passive house products in 2012. Passive building was still tiny then compared to what it has grown into now.

PHIUS and its membership organization the Passive House Alliance US (PHAUS) – the leading passive building research institute and alliance in the US – is the anchor of Passive Building Place for the fourth straight year.

NESEA never stands still. In its topic selection for conference workshops and presentations it continues to ask the tough questions and pushes the boundaries. I am talking about the passive building standard adaptation work we have been doing on Tuesday in a half day workshop. On Wednesday afternoon as part of the core conference I’ll be presenting about very exciting multifamily developments specifically. The Passive Building Place has become a mainstay and is expanding every year with new manufacturers who have recognized that passive building will be a significant driver for high performing materials and components.

Larger projects like Orenco Orchards in Eugene, Ore.,  by CPHC® Dylan Lamar and GreenHammer are coming on strong–they need more manufacturers to step up to the multifamily and commercial passive building market.

But, as multifamily and commercial projects come on strong, we see hesitation amongst manufacturers regarding new components and material needed for larger building developments. This follows the past trend with single family passive homes: the architects and CPHC®s (Certified Passive House Consultants) have taken on the design of the first larger buildings find themselves ahead of the curve.

While this might sound glamorous to some, in practice it is quite a challenge for the teams. Architects are out to make ambitious reductions in energy and carbon with large buildings, and they need appropriate high performance components. In principle, much of what’s been learned and accomplished in single family applications is transferable. Ideally, however, manufacturers will develop turnkey and warranted solution packages for multifamily and other large buildings. What about superinsulated thermal bridge free airtight curtain wall systems? Is this too much to ask for?

Here’s a good place to start: At last year’s 9th Annual North American Passive House Conference in San Francisco, five leading multifamily passive building teams came together for a presentation.  The one component they all wanted was a fire-rated door, that complies with ADA requirements of a low threshold, is airtight and has exceptional thermal performance comparable to the passive house windows that have taken the BE Passive Building Place by storm over the past few years.

To see what’s cooking this year, we are back for another tour of the trade show with you! I will have the pleasure of guiding a tour on Wednesday, March 4 beginning at 5.30 pm just before the boat tour. We’ll be visiting exhibitors who offer products and components germane to the passive building community. We will stop at selected passive building place exhibitors and Passive House Alliance sponsors inside and outside Passive Building Place. Because there are so many it’s impossible to visit all–instead we’ll focus on innovations and a more in depth conversation of 5-10 minutes discussing the manufacturers’ products.

Also different this year:  We will take the investigative role and instead of highlighting the passive building products we’ve seen in past years, we will challenge vendors with a different question: What are you doing to support larger passive building developments? Are you seeing the effects from it in your practice and what are you doing to respond, to prepare for it? Are there new offerings in the pipeline? What are designers asking for, what is missing?

Our goal is to identify the gap so that we can fill it. We like to inspire manufacturers to take the growth in passive building seriously. Please join us on this tour to hear from manufacturers what they are hearing and to ask the right and tough questions to inspire more high performing systems development for larger U.S. passive buildings.

Twenty-four exhibitors are joining us this year in the Passive Building Place or elsewhere on the floor–they include sponsors of PHAUS, firms with PHIUS certified professionals on staff, firms offering PHIUS verified windows or doors, or that are collaborating with PHIUS/PHAUS otherwise.
