Pre-conference starts on Tuesday, Oct. 12, with a trio of diverse sessions. One of our most highly anticipated sessions is “Phius Critical Path for Large-Scale Buildings” presented by BR+A Consulting Engineers Senior Associate and Phius Board Member Prudence Ferreira. With more than a decade of passive house experience to work from, Ferreira will share her approach and tools for approaching the more complex, large-scale Phius projects.

She has outlined the following learning objectives for the workshop:

  1. Define Phius critical path items and process
  2. Explore strategies and tools for managing complexity
  3. Examine energy modeling approaches for large-scale projects
  4. Analyze Phius protocols unique to large-scale projects

For those looking for a broader, more introductory workshop, there is “Passive Building 101” presented by Phius Co-Founder and Executive Director Katrin Klingenberg. This session offers a high-level overview of passive building, covering topics such as: passive house history, rationale for passive building standards, five core principles of passive building, certification processes, benefits of certification, and more!

Things won’t slow down on Oct. 13, as the sessions listed below make for a full day of passive building education and discussion.

  • Prescription for Better Buildings: Phius 2021 Prescriptive
  • Climate and Social Equity Workshop
  • Developer’s Multifamily Buildings of Excellence Case Studies
  • What’s My Size: Using the Newly Revised Manuals for VCHP Sizing

The “Climate and Social Equity Workshop” is free to attend, but registration is requested. It will be hosted by Clean Energy Works Managing Director Tamara Jones, HLW International Designer Satpal Kaur and Topsight Advisors LLC Principal Bomee Jung. The workshop will ask attendees to think critically about the topic of climate justice, which is the principle that actions to mitigate or adapt to climate change should equitably distribute their benefits, redress existing inequities, and dismantle institutional racism.

Mitsubishi Electric Trane US Sr. Product Manager Kimberly Llewellyn’s “What’s My Size: Using the Newly Revised Manuals for VCHP Sizing” workshop promises to be another highlight of the second day of Pre-Conference. She is one of the top mechanical systems experts in the country, and her presentation will focus on the management of humidity loads in high-performance buildings. Questions answered during the session are to include: When is an ERV enough to maintain acceptable interior conditions? What is the interplay of efficiency metrics for dehumidifiers vs heat pumps and where do rating metrics need to go in order to support development of HVAC equipment that can operate optimally in low SHF conditions?

We also don’t want you to forget about the New York City Passive Projects Tour, which is slated for Oct. 12 as well. Attendees will explore some of the largest, most innovative projects in the country. 

If you can’t get enough of Phius and passive house, you belong at PhiusCon 2021 Pre-Conference. Pre-Conference and Tour tickets are sold separately, so be sure to buy yours today!

 

When Sam-I-Am Met Kat in the Hat

Sam is sorely missed.

Sam is sorely missed.

PHIUS co-founder and Executive Director Katrin Klingenberg reflects on the one-and-only Sam Hagerman. 

It was 2008 when PHIUS launched the CPHC® training in Urbana, Illinois—it was so successful that we took it on the road in 2009. First stop was Boston in the East, then a West Coast swing through San Francisco, Portland and Seattle.

Back then, we delivered all training in-person. All students attended three segments with a few weeks in between each—it required a serious commitment. Though the passive movement was nascent, a cadre of forward-thinkers filled all our dates and locations. One of them was Sam Hagerman.

I was fortunate to meet Sam during the second segment of our West Coast swing.
The Integrated Design Lab in Seattle had graciously agreed to host the training. The class room was full except a seat in row two in the middle. Sam was fashionably late and made an entrance, stopped the class in its tracks, scootched past people on the right, charmingly smiling and cracking a joke, all eyes on him, including mine.

Sam could command a room.

He wore a casual plaid jacket, casual to a point of laissez faire, he had pizzazz, a combination of vitality and elan that stuck with me. I wasn’t sure he had staying power to last through serious calculations and building science but he did. This, in spite of having to step out frequently to make calls; he clearly had a bustling business.

I learned later at a class social event that Sam was a builder from Portland, owner and founder of Hammer and Hand. Eventually Sam offered me a ride, and we stopped at the grocery store getting a bottle of wine and a giant bag of cherries.

These are my most valuable memories of Sam, first impressions count and I remember every second of it. It was a good one.

Soon thereafter we held the Third Annual North American Passive House Conference in Urbana, when we founded and launched the Passive House Alliance. I asked Sam if he was interested in chairing it. He clearly had construction, business and political acumen, people skills and plenty valuable connections up the food chain. He graciously accepted the invitation and the rest is history.

Sam Hagerman became the driving force and the bedrock, took us all patiently by the hand, mentored us and me in countless phone calls, advice on industry politics, and strategy. Sam was determined to make passive building mainstream, and to save the planet. We were on a mission together.

Sam had an endearing frontier kind of charisma, combined with big-city business acumen. Most of all, he loved people and his friends and they loved him. He was wont to generously throw parties for them at a nearby restaurant. He brought everyone together and was just a hell of a lot of fun to be around.

He also saw talent and attracted talent. At the training in Seattle he met Skylar Swinford and took him under his wing at Hammer and Hand. What Skylar and countless others learned was that working together with Sam always also meant being friends, having fun and exploring.

I was lucky enough to experience him and Zack Semke, two peas in a pod at the time, on our trip to Innsbruck for the international Passive House Conference in 2011. We ran into them coincidentally on a mountain hike, sat in the sunshine at a small restaurant up there with Graham Irwin and Mike Kernagis…good times! (I hope you’ll view Zack’s tribute to Sam.)

He weathered some early storms within the passive house community as the chair of a rambunctious bunch, including some personal attacks, but nothing seemed to faze him. He kept his eyes on the prize nonchalantly and brushed off slights and difficulties like they were nothing. And in the big picture they weren’t; another valuable lesson learned for all of us.

Under his leadership his firm went on to build one of the very first PHIUS certified passive houses: a ground-breaking positive energy project in the Northwest called Karuna House. The project was way ahead of its time, in a stunningly beautiful setting and the name deeply meaningful. Karuna in Sanskrit means compassion and self-compassion, it is part of the spiritual path of Buddhism. This is how I will remember Sam…the Karuna House spirit.

Life is fragile. He had demons as well, as all artists and deeply thinking and feeling people do, those who are not afraid of living and taking risks. And he was not. And he met his limits eventually, just way too early.

He was a celebrity in his own right, out there, building bridges where he could, creating, playing music (the sax), bringing joy. He was having it his own way. Always.

Sam, you will be so missed, the community is no longer the same without you.

A star has fallen.

Make a wish.

Passive house for the rest of us

Since 2008, when PHIUS launched its consultant training program, more than 500 architects, engineers, and energy consultants have taken the training, passed the computer-based and take-home exams, and earned qualifications as a PHIUS Certified Passive House Consultant (CPHC®). This group has driven the growth of passive building in the United States and Canada.

With the advent of the new format for our CPHC training—which delivers Phase I via live virtual sessions, becoming a CPHC has become more affordable and convenient, and the number of CPHCs continues to grow. (The next virtual program begins August 20, and in-class locations for September include Washington, D.C.; Golden, Colo.; and Providence, R.I.)

CPHCs can’t do it alone, though. That’s why we launched the PHIUS Certified Builders program last year – to develop a community of builders who understand passive principles and can work side by side with CPHCs on projects.

And, now, I’m happy to report that in partnership with  the Northeast Sustainable Energy Association (NESEA), we can offer training tailored to another critical audience: firm owners, managers, policy makers, developers and other project stakeholders who want to know about passive house, but for whom full CPHC training is not appropriate.

This group of professionals are critical to the making passive building mainstream. They need to understand passive house fundamentals — to speak passive house — but don’t need the same kind of hands-on training and technical expertise that architects and builders do.

The new NESEA BE Masters program – called Passive Building Fundamentals — meets this need. I’m working with NESEA’s experienced online training team to create a series of modules. Participants have between September 23 and November 29 to complete the 10-module program on their own time and their own pace .

Like our CPHC training, Passive Building Fundamentals will give participants a firm grounding in the fundamental building science principles of passive design: Superinsulation, airtight envelopes, management of solar gain, ventilation strategies, and a look at climate-specific challenges.

Unlike CPHC training, however, the course will focus on these fundamentals, but not delve into the intricacies of passive energy modeling – a capacity that designers need, but managers and other decision makers do not.  Participants will learn everything they need to know to work with CPHCs and passive building teams, managing and quality assuring the process, managing risk–and making the sale.

Whether you own or manage an architecture firm or construction business; you’re a commercial or an affordable housing developer; a government policy maker; or you’re thinking about building your own passive house: This is the program for you!

Part 3: NESEA BE13–the passive building journey continues…

 

OK, the finale! In part one we looked at the growth of passive building and how it’s reflected in Passive Place at BE13.

In part two we embarked on the passive building tour of the BE13 trade show floor–mapped to the fundamental principles of passive building.

Today, we introduce some unofficial passive building principles and visit some terrific partners.

Onward!

Unofficial passive building principle No. 6:

ASSURE QUALITY AND MEASURE YOUR SUCCESS!

Only PHIUS+ projects earn the plaque!

PHIUS (www.passivehouse.us) offers certification programs for projects and products. PHIUS+ Certification for new and retrofit applications is the only voluntary certification program in North America that requires a thorough design as well as an onsite third party review process. PHIUS+ certification is the most rigorous on the market–and the best value. That’s because PHIUS has partnered with the Department of Energy and RESNET. That means industry-standard certification protocols for design and onsite verification. And it means one-stop certification shopping. Earning PHIUS+ Certification also nets a HERS rating, DOE Challenge Home Status, and EnergyStar status.

PHIUS+ has jumpstarted certifications. We expect to have fully certified approximately 100 passive building projects by the end of 2013 in North America (if apartments are counted, then the number is closer to 200) and yes, the growth is exponential!

At the 7th Annual North American Passive House Conference in Denver last September, PHIUS launched its Window Data Verification Program. In cooperation with NFRC PHIUS is identifying a North American window data verification protocol and climate appropriate guidelines and recommendations. Several leading window manufacturers have signed on and submitted various window frame and glazing combinations for calculation and verification, and listing in the coming PHIUS window data base.

PHIUS recently partnered with PowerWise Systems–Booth 961 (http://www.powerwisesystems.com/passive) to promote their newest product – the inView Passive™ monitoring package. PowerWise offers all kinds of monitoring solutions for all building types—but we’re really excited about the value that the inView Passive monitoring package brings to our community. For passive builders, the proof is in the pudding–monitored performance is where it’s at. inView Passive includes monitoring dashboards optimized for typical passive house components and systems. We think it’s a great tool for anyone certifying a project through the PHIUS+ Certification and Quality Assurance Program.

Besides verifying predicted performance, monitoring systems like inView Passive can serve as early alerts for routine maintenance. For example, energy consumption might rise because a filter in the ventilator has not been cleaned on schedule. Monitoring also provides safety. Say one of the two ventilator fans fail; this could depressurize the house. Without monitoring, it might take some time to notice that indoor air quality declined, back drafting on vented appliances or fireplaces might have occurred or radon levels might have climbed.

inView Passive includes dashboards for typical passive house systems and components and indoor air aspects. Even a closed ground loop defrost system dashboard is included. Information on ordering the system and prices can be found on PHIUS’s website or on the PowerWise website. PHIUS has negotiated a 5% discount for all PHIUS+ certification enrolled projects and the Promo Code is available through PHIUS when registering.

The Energy Conservatory–Booth 828 (http://www.energyconservatory.com/) is the PHIUS+ Certified Rater’s best friend. Commissioning equipment for low load and airtight superinsulated homes has become more sophisticated and is now affordable.  What exactly has to be commissioned and tested? The most obvious—the air-tightness of the envelope needs to get tested during construction and then again upon project completion. For very tight homes the rater can now use the Mini-Fan Blower Door System, a duct blaster in a newly developed red door insert to test the entire building, A small fan is all it takes if the home is that tight! The mechanical ventilation system also has to be commissioned and flows have to be verified. Very small ventilation air flows need to be measured. The Energy Conservatory Flow Blaster Accessory measures air flows at diffusers down to very low levels such as 10 CFMs. And lastly FLIR infrared cameras are used to check insulation quality, thermal bridging and also interior surface temperatures. Indispensable tools throughout QAQC process to verify a building has been built as designed and performs.

 

Unofficial passive building principle No. 7:

SPREAD THE WORD, SHARE THE TALE AND TEACH ALL YOU HAVE LEARNED

The leading national passive building research, education and alliance organizations are the Passive House Institute US (PHIUS) (www.passivehouse.us) and the Passive House Alliance US (PHAUS) (www.phaus.org).

PHIUS was founded by myself and Mike Kernagis in 2003, initially as Ecological Construction Laboratory, a non-profit, promoting and building passive houses for low income home buyers. It changed its name later to Passive House Institute US when it went national. Since 2008 PHIUS has been offering the hugely successful CPHC®Passive House Consultant training nationwide (NEW in 2013: Virtual segment online saving cost and travel time), we have added Certified PHIUS+ Rater trainings and PHIUS Certified Builder trainings over the last few years. We have trained more than 800 architects, engineers, energy consultants and builders and have certified more 500 of them as CPHCs, PHIUS Certified Builders and PHIUS+ Raters in the US and Canada. These are the folks you want on your passive building team!

In 2013 the renowned Fraunhofer Institute for Building Physics, PHIUS and Owens Corning collaborated on a new next-generation passive building modeling tool – WUFI© Passive. WUFI Passive now replaces PHPP as the backbone tool of the CPHC training. Like PHPP, the tool includes a static passive house energy balancing capability. But it also offers dynamic whole building energy modeling and individual component hygrothermal analysis. And it covers another critical modeling variable: thermal mass, which is necessary for the cooling energy balance. In WUFI Passive all of these assessments use the same project data; no double entry of project data in multiple modeling tools is necessary. Risk and performance management all in one. This tool is seriously cool!

In 2009 PHIUS launched a membership/chapter program, the Passive House Alliance US (PHAUS). The mission: to support the community of professionals who had been trained, to educate the public, and drive the market by involving manufacturers and advocating for making passive building standards the norm in North America. Since Mark Miller took on the Executive Director role of this ambitious program in 2011, PHAUS has a thriving and growing membership program, now up to 350 members. PHAUS’ manufacturer sponsors program (amongst them founding sponsor CertainTeed and Rocky Mountain Institute) is growing, as is the chapter organization—now up to 13 nationwide Chapters with two pending.

PHIUS and PHAUS have significantly shaped the landscape of passive buildings in America over the past 10 years and will continue on our mission: the transformation of the marketplace to make passive buildings commonplace. We are a non-profit and if you like what we have done so far and would like to help, you can donate to PHIUS, become a PHAUS member, or certify and train with us.

Building Science Corporation (http://www.buildingscience.com/)  has been a leader in high performance building consulting and education for decades. BSC Principal Joe Lstiburek was a pioneer way back in the 1970s; that’s why at his keynote address at last year’s 7th Annual North American Passive House Conference, he closed his presentation with: “You guys are family.” I was totally moved—and I wasn’t alone. It was inspiring. Joe started building superinsulated buildings in the late 70s when he was just 23 years old!!! The details matched what we consider to be good passive building practice today. He has been on the forefront all along – vapor retarders, thermally broken fasteners, insulated foundation systems, energy heel trusses and even earth tubes (which he is not a great fan of )(link to his article). He knows what the trenches look like.

Building on that energy from the conference, BSC and PHIUS resolved to work together in promoting passive buildings. A first step: We decided to cooperate on the Passive Building University which lives on the PHAUS website (link): BSC bookends PHIUS executive certification classes with a Building Science Fundamentals program, the ultimate preparation for the CPHC Passive House Consultant class. BSC also offers Advanced Hygrothermal Analysis, truly building a science master class. I encourage you to visit BSCs table as they have the best selection of  cutting edge literature that applies to passive buildings. Be prepared to spend some money and schlep books home!

The most recent Yestermorrow CPHC class.

Yestermorrow Design/Build School (http://www.yestermorrow.org/) This past December I arrived in Warren, Vt.,for the second CPHC class offered through the Yestermorrow Design/Build school. Yet another full class, intense and dynamic.

How is Yestermorrow different? It teaches all modules in person on 8 consecutive days with the exam on the 9th. People are on site 24/7, they form study and discussion groups beyond the class time and prep for exam together. You talk bonding…the food is exceptional and the people who show up for this are some of the smartest and unique. Yestermorrow truly attracts exceptional individuals. The classes took the passive discussion to new heights and aside from that, Vermont is just stunningly beautiful – an unforgettable learning experience with a retreat flavor.

Passive House New England (http://www.passivehousenewengland.org/) is one of the first independent passive house groups in the country. Many of its members are some of the most experienced CPHCs in the country with one or more certified passive houses under their belts. This group is a great resource for anyone who is interested in building a passive house or building in the North East region. The group has a very active meet up group schedule and hosts a passive house symposium annually in the fall highlighting most recent projects of special interest. Great group: Get involved!

Passivhaus Maine (http://www.passivhausmaine.org/) is carrying flag in Maine in regards to passive house (don’t you love the lobster in the logo?). This is also an area that has very many experienced passive house consultants and builders solidly on their way. This group also is making strides by providing great information and by putting on symposia. Join the meet up group and help getting the word out!

Well, that’s about it–and that’s plenty!

Thanks to NESEA and all the friends out East that have given me the opportunity to do this review and I hope to see a few of you on the BE13 NESEA trade show floor!!!!!!

 

CPHC® goes virtual – Training to become a Certified Passive House Consultant now more convenient and affordable

The PHIUS Certified Passive House Consultant (CPHC) training—launched in 2008—is the first and still only training program geared to North America’s unique climates, construction details and market conditions. Over the years we’ve made strides toward streamlining the process—for example, we’ve implemented computerized testing at the end of each session, offered the training at multiple locations across the United States, and offered more standalone test opportunities nationwide. As a result, PHIUS is far and away leading training provider in the United States and Canada. More than 850 professionals have takend the 9-day training; 450 have gone on to pass the exam and earn the CPHC credential.

Now it’s time to take another leap forward. During our recent constituent survey, you were good enough to spend your valuable time and give us your feedback and loads of great suggestions. Many of you said that you want to take the CPHC training but you simply couldn’t  be away from work for 9 days; that traveling once for a five-day session was a limit. That the time and travel for two in-class sessions was just too much.

We heard you: To make the training more accessible, we are making a portion of the class available in live, virtual format:

  • Phase I will now be available via eight three-hour virtual sessions presented in collaboration with GreenExpo365, a national leader in virtual sustainable building training. Lecture and homework sessions—which are well-suited for this format—will be delivered twice a week for four weeks. The sessions will be taught live by PHIUS trainers and will feature live interaction. They will be also be recorded and made available to registered students for review and exam prep. Instructors will also hold “office hours” outside of class time to field questions from participants.
  • Phase II will still be delivered in-class over 5 days—students can choose the most convenient of several in-class locations  in the US and Canada. (See schedule here.)

The new format cuts travel and accommodation requirements in half. It allows students to take Phase I from their home or office. And—it allows PHIUS to reduce course fees, which are being reduced by $300! (See the full description here).

We’re very excited to launch this new format in April (see the schedule here) and we think it will open opportunities for more and more professionals to become CPHCs.

Still, you might be wondering why we have not taken the entire training online.

A proficient CPHC must fully understand the core underlying passive house principles, and have ability to optimize a project’s

For modeling and other training components, there is no substitute in-class in-person instruction.

energy balance and performance,  all within the context of a realistic budget.  Years of in-class instruction have taught us that mastering tools like WUFI Passive or PHPP demands personal interaction. Classroom give-and-take between a student and experienced instructor is critical to understanding work flows, appropriate component choices according to climate, and making cost-effective design choices based on modeling results.

In person, group interaction also greatly enhances the mechanical systems design exercises. Perhaps most important: We’ve seen firsthand the kind of personal connections that develop among classmates and between students and instructors.  It has fostered a spirit of sharing and exchange, and forged connections that are the foundation of the passive house community. It has made us strong.

The PHIUS CPHC curriculum is constantly evolving—and it’s better than ever. It reflects the ever-growing collective knowledge and practical experience of our trainers–the most active CPHC consultants, who have build the most certified projects nationwide. Students received a binder of passive house information as well as CDs of class content.

And the CPHC training now incorporates  the new  WUFI Passive modeling tool. It is truly the dawn of a new age for passive designers! In addition to integrating WUFI Passive into CPHC training, PHIUS is offering three-day, standalone WUFI Passive training. It’s a great opportunity for CPHCs to refresh and upgrade their modeling skills.

I just finished participating in the first ever WUFI Passive 3-day training at Parsons College in NYC. CPHCs from the Northeast, Southeast, the Midwest and California and even CPHCs from areas with extreme climates like Texas and Toronto made the trek—and the energy was fantastic! (We just added WUFI Passive trainings in Chicago and Portland, Ore.)

This is a modern production tool with a terrific user interface. On day one we created a 3-D visualization in Sketch-up, imported it into WUFI Passive,  and assigned window properties to the model. On day two we built assemblies in WUFI P in the 3D detail visualizer and on day three we’re trying out the dynamic options of the model for hygrothermal and comfort assessments.

We’re very excited about this new tool and the new CPHC training format. We expect that our partnership with the DOE—PHIUS+ Certification now also earns DOE Challenge Home and Energy Star designation—will put passive house on the national stage. And the demand for CPHCs will grow faster than ever.

We hope to see you all in 2013 and hope you will find the new format as exciting as we do!
