Additional Speaker Information

Dylan Lamar is among the leading Passivhaus consultants in the country, having designed Passivhauses since 2004 from Illinois, to New Mexico, to Oregon. He has translated the PHPP into IP-units, in 2008 and 2014. He has also worked on many Passivhaus first’s in the nation including office/educational buildings, affordable single-family and the largest multifamily Passivhaus (currently under construction). 

Program Description: This will be an interactive workshop introducing and guiding participants through use of the designPH Sketchup plugin and how to best integrate with the PHPP-IP v2.0. We will review best practices in the use of these tools for planning and certification purposes. Participants should bring a laptop installed with registered versions of Sketchup, designPH and the PHPP-IP v2. Sketchup and PHPP experience are strongly recommended to get the most from the workshop. 

Dan Whitmore has worked in the construction industry since 1987 as a carpenter, general contractor, builder, and consultant with additional stints as a designer and FEMA Inspector. His introduction to high-performance building came at an early and impressionable age when, in 1977, his family built an award-winning Solar Home in Oklahoma, where he grew up. As designer, builder and Certified Passive House Consultant in 2010 he completed one of the first Passive Houses in Washington State. As a part of the Hammer and Hand, Inc. team he concentrates on project development and implementation in the Seattle market in addition to energy and building consulting throughout the region. Additionally he is an Instructor for the Passive House Institute US, co-developer of the PHIUS Builders’ Training program, Board Member of the Passive house Alliance US and a founding Board Member of Passive House Northwest.

Program Description:  At the helm of any construction project is the builder, interpreting the intents of the architect, engineer, and client to bring vision to reality. While Passive House methodology is not rocket science, it does add complexity and nuance throughout the construction process, often in ways new to the North American builder.  Dan’s workshop will pull from his experience building and consulting on twenty Passive House projects as well as the insights of countless Passive House builders from across North America. Session participants will come away with an understanding of the various components that go on into Passive House buildings with special focus on those developed for the Pacific Northwest, how those components differ from standard construction, and how they go together into a holistic solution that delivers durability, efficiency, comfort, and health.

Bronwyn Barry designs buildings, products, organizations, marketing campaigns and events - and prefer sto play in the high performance sandbox with the bold and adventurous. Her diverse skills are optimized by a love of collaboration, a startup mindset and a formidable work ethic. An international background and unconventional training have fostered a creative mind and ability to problem solve. Her specialty is achieving results through relationship and team building. She has strong connections across a broad spectrum of disciplines, from policy makers and researchers, to contractor and energy modeling communities. These relationships span the globe. Her fascination with structure extends to systems and organizations. She is a disciple of 'Bright Spot' theory and enjoys using that technique to rapidly scale and replicate systems that are already working. When not focused on buildings, she can be found on Twitter, mining new information, making new friends or simply enjoying a bit of global banter. Bronwyn currently enjoys working as the Design Director at One Sky Homes - a Silicon Valley Net Zero and Passive House Design|Build company. She periodically consults to window manufacturers on high performance profile design. Her volunteer time is spent in service to Passive House California and the North American Passive House Network.

Program Description: There is an increasing need for optimization tools in the Passive House community.  Running hundreds of PHPP iterations is not only complicated, but time consuming – unless this process is automated.  Fortunately for us all, this is exactly the task that computers are good at.

Gary Klein, President of Gary Klein & Associates has been intimately involved in energy efficiency and renewable energy since 1974. One fifth of his career was spent in the Kingdom of Lesotho, the rest in the United States. Mr. Klein has a passion for hot water: getting into it, getting out of it and efficiently delivering it to meet customer's needs. After serving 19 years with the California Energy Commission, he has provided consulting on sustainability since 2008. Mr. Klein received a BA from Cornell University in 1975 with an Independent Major in Technology and Society with an emphasis on energy conservation and renewable energy.

Program Description: Once we build a very high performance building from the perspective of heating, cooling and ventilation and install high efficiency lighting and plug loads, we are left with what to do about hot water. Hot water is a system: heater, distribution piping, plumbing fixtures and appliances, waste heat that runs down the drain. This session will discuss practical measures you can incorporate into your next project that result in high performance hot water systems and very satisfied customers. Bring your floor plans and your questions. We will demonstrate the principles, not just discuss them!

Zack Semke: Zack is director of business development and chief evangelist with Hammer & Hand, a Portland and Seattle-based construction company dedicated to inciting evolution in building through service, craft, and science. http://hammerandhand.com Founded in 1995, the firm specializes in high performance building in the commercial and residential realms, with projects like Karuna House, the first in the world to achieve the triple crown of Passive House, Minergie, and LEED Platinum certifications. After graduating from Stanford University with a degree in Human Biology: Human Ecology, Zack began his career with the then-fledgling Coalition for a Livable Future, supporting its work in the ‘90s to advance progressive planning policy in the Portland region. By 1998, Zack’s passion for beating on huge drums beckoned and he devoted himself fulltime to co-directing Portland Taiko, leading the group’s organizational development, fundraising, and artistic programming, and performing for half a million people across the US. In 2005 Zack returned to his interest in the built environment, enrolling in the design program at the Landscape Institute in Boston. It was through his subsequent work as a designer at Shapiro Didway Landscape Architecture that he was introduced to Hammer & Hand. He joined H&H in 2010.

Lloyd Alter: Writer / Toronto. Lloyd Alter is managing editor of TreeHugger. He has been an architect, developer, inventor and prefab promoter. He contributes to The Guardian, Azure and Corporate Knights magazines, and is Adjunct Professor teaching sustainable design at Ryerson University School of Interior Design. Lloyd is a Past President of the Architectural Conservancy of Ontario. In the course of his work developing small residential units and prefabs, Lloyd became convinced that we just use too much of everything- too much space, too much land, too much food, too much fuel, too much money, and that the key to sustainability is to simply use less. And, the key to happily using less is to design things better.

Program Description: The smart home is the hot subject in the news these days, with technology becoming embedded in everything in our homes and offices. Much of this technology is being developed as add-ons to our existing building stock, in attempts to provide better control, comfort and energy efficiency. The presenter will make the case that this is the wrong approach, that it is counterproductive and possibly dangerous, and that it is usurping the role and responsibility of the architect, replacing good efficient and effective design with technological band-aids.

Günter Lang: Since 2001, LANG Consulting's intensive passive house networking, research and consulting work have made it a world-renowned passive house expert. In close cooperation with the Passivhaus Institut, Günter Lang has made a major contribution to networking passive house stakeholders worldwide and publicizing the passive house standard. In 2013 the Passivhaus Institut together with Günter Lang formed Passivhaus Austria – an expert networking group led by Günter Lang.  Prior to leading Passivhaus Austria, Günter Lang was the manager of IG Passivhaus Oberösterreich for ten years. LANG Consulting conducts theoretical research and pioneering demonstration projects. Günter Lang presents his findings promptly and widely in numerous congresses and technical meetings worldwide. Günter Lang suggests that if you really want to get understand passive house, you must experience it for yourself. This is why Günter Lang has shown his own passive house – Austria’s first certified passive house - to thousands of visitors and conducts expertly-guided excursions to other passive houses for visitors from all over the globe.

Keynote Summary:  Europeans are redeveloping entire city districts with passive buildings. Travel with us to the Bahnstadt district in Heidelberg completed in 2015 with $2.6B US in new passive house apartments (5,000 dwelling units) and commercial buildings (7,000 work spaces).  And see the Eurogate district in Vienna – the first passive house district worldwide. With every building meeting the Passive House Standard, the world’s most rigorous energy-standard. And Brussels, Belgium, where every new building constructed or substantially remodelled since January 1, 2015 must meet the Passive House Standard. See 10- and 20-story skyscrapers, both new and retrofitted, that meet the Standard, and learn how their energy intensity is a fraction of comparable US buildings.  Gunter Lang, an Austrian Passive House researcher and leading expert on large-scale Passive House developments, will present these developments and explain why developers, building owners/investors, and government officials decided these skyscrapers, districts, and cities must meet the Passive House Standard.

Julie Kriegh: KRIEGH ARCHITECTURE STUDIOS, founded in 2000, focuses on high performance residential buildings and neighborhoods. Julie Kriegh, AIA, LEED AP, and international CPHC advocates strategies that are Aggressively Passive, using high performance building, sustainable site, and community design modeling to achieve low-energy demand and low-impact site design community wide. She holds degrees from Duke University and University of Washington (Master of Architecture) and is currently pursuing a PhD researching occupant behavior.

Mike Fowler:
Mike is an Architect at Mithun, a design firm working to inspire a sustainable world for people and the planet through leadership, innovation, and integrated design. His 25+ years of experience on award-winning projects includes two net-zero energy designs and six LEED projects. He has served on two Technical Advisory Groups for the Washington State Building Code Council (Green Building and the Energy Code) and chairs the Codes and Planning Policy Committee for AIA Washington Council. Recently, Mike managed the Multifamily New Construction and the Residential New Construction energy efficiency financial incentive programs at Puget Sound Energy. There he created the first and only whole-building residential measure in the country with an incentive for predicted low-energy-use design and a bonus incentive for actual metered energy use hitting the design target. Mike has authored a peer-reviewed outcome-based energy budget code proposal (original 2012 proposal and current 2015 proposal to Washington State) that sets an energy use budget for eleven occupancies/uses, establishes a road map to achieve 70% energy use reduction compared to 2003 baseline by 2030, incorporates site and building design with the future ability to generate 40% of the energy budget with renewable energy, and sets the stage for buildings with low energy use to participate in a future state cap and trade program.

 Russ Weiser: Russ has a background in Science and worked as an Assistant Professor at Virginia Tech before becoming an Architect.  Russ studied Architecture at University of Oregon and worked at the Energy Studies in Buildings Laboratory (ESBL).  Working at HKP Architects since 1999, Russ is familiar with all phases of sustainable design and has a keen interest in reducing barriers to Passive House Construction.

Program Description: High performance new construction residential buildings strive to meet their predicted energy use targets as modeled. However, meeting stringent targets can remain elusive due to: development cost hurdles, funding sources, delivery methods, construction quality, and occupant behaviors.  To address this issue, the authors take a deep look into an iterative project delivery process (Agile) designed to target high performance quality construction (Passive House) and leverage strategic financial incentives (Elegant) for an early investment of time and resources leading to better outcomes with greater transparency and assurance of success.  The Agile project delivery method was developed in 2001 by the Software industry to increase the success rate of innovative product delivery.  Applied to the construction industry, the Agile process necessitates the assessment of the project iteratively to promote innovation and accountability focusing on people and values as well as project performance goals through feedback and flexibility.  Agile accomplishes projects with lower risk by structuring financial incentives that reward project goals at discrete intervals in the process. Elegant energy efficiency financial incentives from local utilities or statewide programs assist with reducing early project cost hurdles. Incentives open the door to a powerful marketing message that emphasizes increased project value. A groundbreaking example is the new 2014 Whole Building Target EUI and Actual-Use incentive from the Residential New Construction program at Puget Sound Energy. This unique incentive provides higher financial incentives to lower energy use targets and it rewards projects that prove actual energy performance over a full year with additional dollars. Passive House buildings fit this incentive perfectly. Passive House examples will show how projects can leverage energy savings and incentives into increased financing opportunities, how projects can offer more value for less cost, and how a cash positive project can be achieved using the Agile project delivery method.

Sam Hagerman: For 30 years Sam has worked as a builder, business owner and high performance building proponent.  In 1995 he co-founded the contracting firm Hammer & Hand, emphasizing sustainability in the built and work environments.  He is active in the national and local policy arenas, recently completing a three-year term as inaugural president of the national Passive House Alliance US, for which he continues to serve as board member.  In 2012, Sam completed the first commercial Passive House retrofit in the US, the Glasswood Building in Portland.  In 2013, he finished the Pumpkin Ridge Passive House (one of six super-efficient “demonstration homes” recognized by NW Energy Star) and the Karuna House (the first green building in the world to earn LEED, Passive House, and Minergie certifications).  His current Passive House and other high performance building projects stretch from Yamhill County, Oregon to Seattle, Washington.

Program Description: This presentation will share the evolution in Hammer & Hand’s construction of wood framed Passive House envelopes in the Pacific Northwest. Drawing on seven built projects in Portland and Seattle, the session will examine how each assembly aimed to optimize performance, cost, land use, and durability. The presentation will also chart Hammer & Hand’s move toward developing details that are more familiar to the building community and easy to assemble, moving from unique practice to common practice. A series of detailed, 3D color renderings of the various wall assemblies will illustrate the presentation. The six case studies are: 1. Courtland Place – A fun carpenter’s puzzle with minimal budget; 2. Karuna House – A high design, high performance showcase; 3. Glasswood – Passive House retrofit of a commercial building; 4. Pumpkin Ridge – “Let’s do all cellulose!”; 5. Maple Leaf – Solve problem of walk-out basement;6. Puget – Move toward standard practice; 7. Madrona – Add mineral wool (life’s good between a rock and a hard place). Discussion of each wall assembly will be organized into three categories, Air Barrier, Moisture Management, and Insulation, as follows:1. Sheet goods with tape: Glasswood, Courtland Place;2. Sheet goods or OSB with liquid applied membrane at seams: Pumpkin Ridge, Maple Leaf, Madrona; 3. Liquid applied membrane applied as continuous layer: Karuna, Puget. Moisture Management; 1. Liquid applied membrane applied as continuous layer: Karuna, Puget; 2. Liquid applied membrane at punched openings with integrated membrane WRB: Glasswood,Courtland Place; 3. Liquid applied membrane at punched openings with Agepan (integrated sheet good) as WRB:Pumpkin Ridge; 4. Liquid applied membrane at punched openings and panel edges, with ZIP Sheathing (structural sheet good with factory applied WRB): Maple Leaf (extra credit: mineral wool at Madrona). Insulation1. Cellulose cavity fill with exterior foam: Glasswood, Karuna; 2. Cellulose cavity fill with exterior mineral wool: Madrona; 3. Dense fiberglass with exterior foam: Puget, Maple Leaf; 4. Larsen Truss with cellulose: Pumpkin Ridge; 5. Wall truss with dense blown fiberglass: Courtland Place;This climate-specific examination of Passive House envelope strategies will share construction details, cost-effective strategies, site management considerations, code issues, and how to coordinate Passive House construction practice with existing conventions.

Program Description: Passive house buildings are characteristically designed for low peak or annual heating and cooling loads ("very small furnace size".) One of the selling points is that thermal comfort is improved (and/or that there is less need of distribution systems for heating and cooling.) But to the extent that comfort is a primary concern, it would be better to design for it directly using human comfort metrics, rather than using energy metrics as proxies. For one thing, the benefit of ceiling fans can then be modeled. Also, the fully mixed single-zone building energy models that are usually used for passive design may not be granular enough especially for large buildings. This presentation will introduce the Predicted Mean Vote and Predicted Percent Dissatisfied metrics, review the comfort standards ASHRAE 55, ISO 7730, and EN 15251, and explore how we might use them for comfort focused design, and to make tradeoffs between passive measures and distribution systems, and to quantify the comfort benefits of passive design in normal operation and in outage situations.

Program Description: There have been numerous revisions, and proposals for revision, to the “Passive House Standard,” by both PHI and PHIUS. These changes are intended to extend and enhance the feasibility and scope of Passive House, but they have also
resulted in increased complexity. The “thermal time constant,” a hidden calculation within PHPP, measures a building’s ability to resist changing outdoor conditions. Might this be key to a simplified, yet robust, definition of “Passive?” This presentation will explore this issue and illustrate the environmental and economic benefits of buildings with long thermal time constants.

Andrew Michler: Owner Baosol LLC consulting, writer of Hyperlocalization of Architecture | Sustainable Building Archetypes released April 2015 by eVolo Publishing. Born in Oakland, California Andrew found his way to an pine forest in the Colorado Rockies where he has lived off grid for 20 years. Blending his long time experience in design/construction, art, and sustainable building research into the written word he began exploring contemporary buildings for the environmental design website Inhabitat, eVolo Magazine and other publications in 2010. His newly released book Hyperlocalization of Architecture explores firsthand new environmental contemporary architecture movements around the world including the passive house chapter [Germany Maintains] available for free at www.hyperlocalarch.com.

Program Description: As our building become much more efficient the importance of what we build with becomes a core design consideration. The emerging understanding of the impact of materiality in construction, while still imprecise has a deep and lasting environmental impact. The carbon footprint of a conventional building may be an important but small percentage of its lifetime impact, with Passive House the environmental impact of materials can notably go up as the energy consumption goes down. This is a particularly salient objective when investing in fabric first design and the resulting demand for more raw materials. The goal is to merge the revolution of Passive House and the evolution of low impact healthy construction from the standpoint of the envelope system. Using foam free Passive House construction methodologies Andrew will explore the impact of material selection from an environmental and building perspective. The first project is a small off grid retreat that merges Passive House with Cradle to Cradle inspired methodology to select materials based on environmental impact, health, and life use assessments. This inspired a second foam free mainstream three bedroom Passive House in a typical suburban neighborhood. Material selection and incorporation is examined for the environmental attributes with a focus on mineral wool, cotton batt, and cellulose and to de-emphasize concrete, foams, and plastics. The results are lower cost and more robust wall systems. Other mainstream and fungible low carbon
envelope systems will highlighted as well including heavy timber large construction to emphasis the synergies of scale, material, and energy efficiency.

Program Description: There is a growing demand for building materials that meet low-energy goals while maintaining the health, safety, and wellness of building occupants for the life the building. Many products going into high performance and Passive House buildings today are falling short:particularly spray foam. Foam has come to dominate high performance building by claiming a high insulating value, air tightness, and vapor control all in one product. When practitioners are seeking more environmentally friendly alternatives, they are often left scratching their heads about the options, the details, and the possible results. This presentation will cover the basic building science of high performance enclosures. A wide range of material options such as wood fiberboard, sheathings, membranes, mineral wool, straw bale, cellulose and other insulations will be considered. Airtightness goals will be analyzed, looking at ground, wall, and roof conditions as well as the design, construction, and testing of the assemblies.
The presentation will demonstrate that one can achieve higher performance, greater sustainability, resilience, and building health without foam. We also show how to do it with practical examples, details, and assemblies that make sense for the Pacific Northwest.

Program Description: The concept of the passive house is one of the most enlightened and progressive in the sustainability arena. Passive houses have extremely low energy demands, are more easily made independent of the grid, and are highly functional. Passive building can also be an excellent antidote to efficiency traps that promise to conserve resources but actually increase resource consumption. It would be hard to criticize the passive house movement for a failure to address environmental concerns. Nonetheless, in the spirit of striving to improve our focus and effectiveness I will discuss efficiency traps that could affect the passive housing movement. I will also discuss the passive house movement in terms of the twin crises of fossil fuel depletion and global climate change.

Program Description: The last 30-years have seen some significant changes in the technologies and techniques used in creating new commercial buildings. While this has included significant strides in the energy efficiency and performance of lighting systems, window glazing, building insulation, and HVAC equipment efficiencies, this has not translated to consistently high performing buildings. Typical new buildings are using nearly the same energy use per square foot as buildings built in the 1980s. This presentation seeks to demonstrate how it is possible to meet the ambitious goals of the 2030 Challenge in commercial buildings - Net Zero Energy by the year 2030. To do this we will present lessons from our experience auditing typical new buildings as well as from our
successful design experience producing buildings that are meeting the 2030 Challenge. From these case studies of real buildings we will pull out the essential ingredients to produce highly energy efficient buildings. This points to a new approach to building systems design which we call “Design for Off”.

Program Description: In an increasing market for multifamily - energy efficient - high performance building shells, efficient ventilation strategies become paramount in maintaining human health and comfort without sacrificing high level project such as Passivhaus Certification. So what is the best approach to creating a well-ventilated multifamily building? As with most issues in design, it depends… This workshop will discuss ventilation approaches to be considered from large central air handlers, to individual systems in each dwelling, to options in between. The pros and cons of several strategies will be presented with ample time to pose questions and debate methods. How important is distribution? Is heat recovery necessary? Should occupants have control? How much air is enough? These questions and more will be addressed through outlining general concepts and presenting case studies. Bring your own questions or a specific problem you are struggling with for discussion.

Program Description: When looking at sustainability metrics the building industry has typically focused on energy and water independently. This is reflected in standardized metrics like energy use intensity (EUI) and water use intensity (WUI) but in practice water and energy use in a building is more complex than this. Water and energy are interlinked in intricate and often overlooked ways. This presentation works to show how water use and energy use are interlinked from source to site. This includes the water use intensity of electrical production, building system.

John Hickey:

Program Description: The United States Armed Forces have a colossal "boot print" in terms of real estate owned and buildings operated.   They consume tremendous amounts of energy, and they are working hard on energy efficiency, renewable energy and high performance buildings.  Here are some of the highlights:  The US Navy, for example, is working aggressively to reach its goal of having 1 GigaWatt of renewable energy by the end of 2016.   The DoD will invest approximately $1B in energy efficiency through performance contracting by the end of 2016. All of the services have adopted the LEED Rating Criteria, and several net zero buildings have been completed.   The services are focused on missions, and this has led them to implement micro grid solutions at some bases.  The micro grids will integrate distributed generation assets such as PV and on site power plants with building automation systems and industrial controls to provide power reliability, energy efficiency, and cyber security in order to support their missions.    (this is an area where the DoD is leading, and therefore, I find this the most interesting.)

Program Description: We know that the energy consumption of our buildings is a big contributor to the biggest environmental crisis of our time: global climate change. But what if our buildings could produce more energy than they consume? “Zero Energy Building” presents an enticing vision, but one that depends on a revolutionary reduction in the energy our buildings demand for heating and cooling. The Passive House approach to design and construction achieves this revolution, reducing by 90% the heating energy consumed by our buildings. Zack will present an overview of Passive House, how the building approach provides a practical path to Zero Energy Building, and discuss an important but often overlooked benefit of high performance building: the health and happiness it brings to building occupants.
