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.

PHIUS+: The path to positive energy

Public Comment Opportunity: PHIUS+ Certification for Multifamily Performance Requirements (v2.0)

Chris McTaggart, PHIUS+ QA/QC Manager, wants your feedback…

Dear PHIUS/PHAUS community members,

Adoption of Passive House Institute US (PHIUS) PHIUS+ certification is growing rapidly. Of particular interest is the application of PHIUS+ certification for multifamily buildings. With several projects already certified or in the process of construction, and several more projects in the design phase, PHIUS expects certification of multifamily buildings to be one of the leading growth sectors for high performance, low-energy buildings moving forward.

With this in mind, PHIUS has created updated draft standards for certifying multifamily projects. These updated standards are intended to replace previous guidance offered by PHIUS for certifying multifamily projects. PHIUS is seeking review and comment from all vested stakeholders on these draft standards with the intent that a finalized version shall be released in Q2 2015.

The updated PHIUS+ Certification for Multifamily Performance Requirements (v2.0) contain several improvements to language regarding the specific performance modeling and testing expectations for certification of multifamily projects, including:

  • Modeled energy performance criteria
  • Infiltration testing requirements/protocol
  • HVAC testing/balancing requirements
  • Sampling protocol for dwelling unit-level testing/inspection
  • Additional onsite testing/inspection requirements

To create these draft guidelines, PHIUS solicited feedback from several constituents who are actively involved in the certification of high performance multifamily projects. These comments helped inform the standard development process, and the goal is that the most fundamental areas of need for clarification and formalization have been addressed.

Please take the time to read the attached PHIUS+ Certification for Multifamily Performance Requirements (v2.0) document below and make comments by June 8, 2015. Use the comments section below or email your input to certification@passivehouse.us

Thanks,

Chris McTaggart,  PHIUS+ QA/QC Manager

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.

Comments on climate-specific standards study now open

ClimateSpecificColor
In cooperation with Building Science Corporation, under a U.S. DOE Building America Grant, the PHIUS Technical Committee has completed exhaustive research and testing toward new passive house standards that take into account a broad range of climate conditions and other variables in North American climate zones and markets.

This report contains findings that will be adapted for use as the basis for implementing climate-specific standards in the PHIUS+ project certification program in early 2015. Furthermore, as materials, markets and – climates – change, the PHIUS Technical Committee will periodically review and adapt the standard to reflect those changes.

  • We invite formal comment on the science. Please use this online form to submit. Deadline for formal comment: January 16, 2015.
  • Formal comments will not be public, and are for Tech Committee review only. (The Tech Committee or PHIUS staff will contact you for permission, should we be interested in publishing your comments.) All formal comments will be reviewed, but we cannot guarantee an individual response.
  • Passive House Alliance US Members: An online informal discussion forum is available to all members. The forum discussion will be visible to the general public, but only PHAUS members can make comments. Comments on the discussion forum are not guaranteed to be reviewed by the Technical Committee.
  • If you are not a PHAUS member, use the blog comments section below. Comments on the blog cannot be guaranteed to be reviewed by the Technical Committee. To ensure Committee review, use the online formal comment form.

The North American Passive House Conference in San Francisco – a hard act to follow for NAPHC2015 (in Chicago)

Every year we say “This was the best passive house conference ever, we better stop now, we can’t possibly top this experience, the quality of the presenters, the “meat on the building science bones” presentations, technical details and specific construction solutions, cutting edge projects of all building types showcased throughout all climate zones, policy and government role discussions and incentives… and this year in addition to the Builders’ Hootenanny the Architects’ Hootenanny which, you might have guessed, was a hoot.

Let me take this opportunity to thank our community of longstanding CPHCs, PHIUS Certified Builders and PHIUS+ Raters who have shared this passive building path with us now for almost 10 years. It has been a pleasure knowing so many great folks with their hearts in the right place and a common characteristic: a determined pioneering spirit to make the energy transition in the way we build and live happen. Thanks to all passive building practitioners and to newcomers to the conference especially the international speakers from the UK and Japan.

Together you submitted nearly 100 abstracts and we had a hell of a time to choosing the best ones. We ended up with an unprecedented total of 72 sessions in 4 tracks this year, more than ever before (we cut the plenary short upon your request to get to the meaty sessions quicker and to have more of them).

Special thanks go to Sam Rashkin from the DOE, for his invaluable contributions to the tracks on government perspective and for the great partnership he and the DOE have provided to the PHIUS+ certification program over the past couple of years. Sam took time to be with us on the Sunday tour of passive buildings in the bay area, which was a lot of fun.

I would especially like to thank all of our outstanding pre-conference workshop presenters who covered topics in great depth, most popular were the Multifamily Palooza (kicked off by Chris Benedict who currently leads the field with the most passive projects in this sector realized), Passive Building Science with Joe Lstiburek (our unofficial lounge sponsor), packed the house closely followed by Mechanical Systems and commercial applications. Many thanks to the outstanding instructors who tackled more specific technical issues and new frontiers, such as efficient water systems design by Gary Klein, and Matthias Patzold from the Fraunhofer IBP and PHIUS staff presenting on dynamic energy modeling in WUFI Passive, THERM/windows modeling and PHIUS+ certification QAQC during the rater training. To all our presenters, pre-conference and main session: Thank you all so much! It would have not been possible without you!!!!

We owe many thanks to Michael Hindle, our charismatic Master of Ceremonies, and President of the Board of Managers of Passive House Alliance US (PHAUS). His opening speech was inspiring, artful and philosophical, The Passive House Alliance is now 16 chapters strong with 7 more in formation all over the country. It is starting to develop an impressive momentum regarding advocacy for passive buildings across the nation. Michael pledged to the membership that he would keep increasing member benefits and participation opportunities and closed with a call for action to join the many committees that have been formed to get the work done.

Michael also made a very well received announcement: the PHAUS  board has moved to remove any reference to a specific passive house standard from chapter founding documents. This decision rightly recognizes that since the inception of the passive house concept in the 70s in North America, it has undergone more than just one transformation and that evolution and learning will continue. It must continue to evolve for us to be successful. PHAUS leadership supports the new climate specific Passive Building standards brought forward by PHIUS as part of such evolution.

Bill Rose followed with the most thoughtful, most provocative keynote given at the North American Passive House Conference yet. Many of you came to me afterwards expressing that sentiment. He showed a short video recording from the early 70s of the researchers credited with formalizing the superinsulation/passive concepts. They worked at the Small Homes Council, University of Illinois at Urbana-Champaign in Illinois. The video reinforced the notion that the passive house community has a longstanding history here in the United States. He then showed a document written by the Nixon administration predicting peak oil and climate change to happen in 2010. It was a stunning piece of evidence that the issues had been known then, as well as the possible remedies outlined in the document. The document, then issued a clear call for action, recognizing the emerging passive community as having the best approach for reducing the demand side of buildings.

Rose made clear that facing the climate crisis means we also need to step up to transform the supply side of the system, coming up with strategies of how to keep the fossil fuel reserves in the ground and how to challenge the current economies that are all built around such assets. He ended provocatively saying, that we need to get to a point where we will be saying: “Energy (fossil fuels), what’s that?”

After the keynote and during all breaks, the exhibit hall was buzzing. A big thank you to all exhibitors of high performance materials and technologies! Every year the cast has been expanding significantly and new useful materials and systems manufacturers join the core group of providers. Thank you, without your products and services it would be impossible to realize passive buildings as well as we now do. Of course, also thank Exhibit Hall sponsor Bayer MaterialScience and our lanyard sponsor Hayward Lumber. Bill Hayward joined us on the tour and provides some great local background. Be sure to check the Hayward Health Home, a very cool initiative.

Achilles Karagiozis delivered the closing keynote. He spoke on the view forward, the implementation of passive buildings worldwide in all different climate zones and the challenges and responsibilities that come with it. He stressed the importance of dynamic modeling for accurate energy prediction results as passive building is applied in different climate zones. He cited an astounding example: WUFI Passive is now able to predict insulation material dependence on temperature on an hourly basis. And of course, this is important to assess hygrothermal performance of enclosures as well as to get the energy balances calculated with more accurate granularity. A great new age has arrived for us designers to manage our risks in designing passive buildings, thanks to the emergence of more powerful computing capabilities that make dynamic models feasible.

At closing, maybe best of all, the incredible sense of community of people who trust each other and know each other well:  We have been coming together now for almost a decade, reuniting at this amazing annual event working together to devise solutions for the North American market, its climate zones and building sector.

And this year, for the first time, the event was held in one of the largest and most exciting metropolitan areas: the San Francisco Bay area. This meant a significant step up from the previous conferences and importance in visibility of our community to city and government leaders, in California and beyond.  Passive building has turned the corner. And so has PHIUS as we were more than once told during the event by you.

PHIUS’ Senior Scientist Graham Wright’s presentation on new North American Passive Building Standards that are currently being completed under a DOE Building America grant was very well received: “This sounds like a really good program” was consistent feedback. The interest was so large that the session had to be moved from the break out room to the ball room. Most everybody was in support, not one negative comment! Kudos to excellent work by Graham Wright and a clearly laid out and scientifically founded argument by the tech committee.

And last but not least thanks to the PHAUS San Francisco chapter and John Sarter and Lizzie Adams from PHCA for helping to organize a fantastic tour of project on a beautiful Sunday in paradise: From multiuse building to state of the art office building to residential retrofit projects, it was great!

Thank you all for coming, for your contributions, participation and feedback on what to do better next year. Keep it coming so that the next act will be better yet again… see you in Chicago, details to come!
