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

A message from Chris McTaggart, QA/QC Manager, PHIUS+ Program

New PHIUS+ QA/QC Manager Chris McTaggart

PHIUS has contracted with Chris McTaggart of Building Efficiency Resources to serve as our new QA/QC manager in support of the PHIUS+ Rater program.  For more information on this transition, please read a special message from Chris below.

Dear PHIUS+ Raters and constituents,

I am thrilled to have the opportunity to work with the Passive House Institute US as the QA/QC Manager in support of the PHIUS+ Rater program. My role will be primarily in working with PHIUS+ Raters to provide technical support and quality assurance review of documentation submissions for PHIUS+ Certified projects. Additionally, I will be supporting PHIUS as an organization by participating in the PHIUS Technical Committee and helping to refine and develop the passive house program certification standards.

I would like to thank the previous PHIUS+ QA/QC Manager, John Semmelhack, for his leadership in managing and developing the PHIUS+ Rater program. John is a first-rate professional, extremely knowledgeable building scientist, and an exceptionally personable and friendly person, and PHIUS has benefited tremendously from all the effort John was able to provide to the organization. I greatly appreciate John’s recommendation to PHIUS that I succeed him, and will do my best to pick up where John left off for all of our benefit.

A bit about my background… I am the co-principal and lead RESNET Quality Assurance Delegate (QAD) for Building Efficiency Resources (BER). BER is a national third-party RESNET QA Provider that works with over 150 independent raters and rating companies in 25 states. Throughout the past 6+ years, I have worked almost exclusively in providing technical support, training and mentorship to RESNET HERS Raters to help them understand program standards and how to execute their role in providing third-party verification. Additionally in this role, my company performs QA review of energy rating files both using site verification documentation as well as in the field.

In my role as QA/QC Manager for PHIUS, I hope to achieve the following:

  1. Provide thorough and timely technical support to PHIUS+ Raters and other program constituents regarding the role of third-party verification of PHIUS+ certification standards.
  2. Review all PHIUS+ project certification submissions by PHIUS+ Raters for accuracy in order to ensure that all program certification criteria is being properly verified.
  3. Help refine and improve the PHIUS+ program certification standards and affiliated documents so that PHIUS+ Raters clearly understand their role in performing verification services for PHIUS+ Certified projects, and so that role is as streamlined and efficient as possible.

As many of you know, the PHIUS+ certification standards are being evaluated and updated to help the program achieve greater levels of consistency and participation in the marketplace. A huge part of this process will be to properly codify the role and scope of third-party verification and quality assurance oversight of these standards so that consumers and program constituents are confident in the results of PHIUS+ certification.

My role in achieving success in this development process is clear: help make the on-site verification process for PHIUS+ certified projects as clear, organized and efficient as possible for all parties involved. This will ensure that PHIUS Certified Passive House Consultants (CPHCs), Raters, and affiliated project architects, engineers, owners, etc. will all be able to understand and communicate with one another about the program certification requirements. The end goal of this process is that PHIUS+ Certification and verification criteria is uniformly achieved and projects are successfully certified.

Achieving the above will require significant effort and feedback from PHIUS constituents regarding the current certification process so that future versions of the certification standards are as clear as possible. I encourage all of your participation and communication throughout this process, and encourage you to reach out to me with any questions, technical support issues or feedback that you may have.

I look forward to working with all of you.

Sincerely,

Chris McTaggart

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!

 

 

 

 

California here we come!

I’m just back from San Francisco where I spent five days to meet with stakeholders and contributors to discuss plans for the conference coming up on September 10-14, 2014.

The talks were amazing and super encouraging! PHIUS+ projects in the Bay Area are exceptional – they all are also zero energy or positive energy buildings highlighting that passive building is the ideal starting point for going zero or positive. This growing trend – passive to positive energy — will be one of the major themes for conference sessions!

Combining passive design in buildings plus renewables is one of the strategies identified by carbon reduction groups to help mitigate and adapt to climate change. The latter because passive buildings are especially resilient in weather extremes and power outages.

San Francisco has long been aiming at carbon zero goals by 2020, looking to identify a clear set of tools on how to practically and cost effectively implement them. That’s why we chose San Francisco for this 9th Annual North American Passive House Conference. We think it can be the catalyst for a tipping point, a special moment in time when the concept is catapulted forward thanks to favorable factors in the Bay Area. With plenty of high quality high-performance projects designed and built by the pioneers in the passive community, we have an excellent opportunity to make the case to make to the city and its residents that passive design is the best path to their goals.

On my trip I have spoken with various stakeholders and thought leaders and have seen nothing but honest excitement about the possibilities of the conferencce. And better yet, if San Francisco get’s it, you know that the rest of the state and then the country will eventually follow, hence it is critical to make this a big success that radiates beyond the borders of California setting a definite sign: we are in the transition toward a new energy economy and buildings, passive and renewables will play an important role in it.

We’re excited that William Rose, a building science pioneer, will deliver our keynote and that Achilles Karagiozis, Director of Building Science for Owens Corning and WUFI developer will speak at the closing plenary. Also: Joe Lstiburek will present a daylong workshop on building science fundamentals during pre-conference sessions.

Of course, success of the conference – as always –will depend on the dedicated members of our community. We’ve collected dozens and dozens of terrific presentation proposals (and we’re a week or two behind in our review, please accept our apologies; we’ll be in touch soon), and the content of our breakouts will be terrific, as always. We also have a great range of pre-conference sessions (which als earn CPHC CEUs), including a daylong session with five CPHCs who are leading the way in multifamily builldings. Visit the conference website often for updates.

And if you’re available to volunteer to help, email conference@passivehouse.us with your availability and any special expertise. We could use help with everything from registration desk staffing to videography.

Full schedule — and more announcements on some great presenters — are on the way, stay tuned!
