Key design breakthroughs center on the skeleton, skin and respiratory systems of buildings.
The message from scientists is clear: The planet is on a finite greenhouse gas budget and the longer we wait to reduce emissions, the faster we’ll have to reduce later to avoid catastrophic climate change. Time is of the essence.
While we have made remarkable progress over the past decade in delivering more energy-efficient buildings, we are moving too slowly given the urgency of the climate crisis. According to the U.S. Energy Information Agency’s 2014 projection for building energy use, efficiency gains will be offset by the 60 billion square feet that will be added to U.S. building stock between 2005 and 2030.
That’s not good enough. If we’re serious about our climate goals, we need to bend the building energy use curve downward.
The good news is that we — architects, engineers and builders — can transform building energy performance today. Passive House (aka Passivhaus) design and construction, for example, can reduce overall energy consumption by up to 75 percent and launch the built environment toward the Zero Net Carbon goal recently announced by the World Green Building Council, Architecture 2030 and others. And we can do this cost-effectively and predictably.
Nevermind the gap
Ever since the New Buildings Institute published its 2008 paper documenting the performance gap between modeled and actual energy use of LEED buildings, the predictability of performance in LEED and other high-performance buildings has been the topic of much study and debate.
There is no such debate with Passive House performance. The consistent finding is that Passive House modeling (via the Passive House Planning Package or PHPP) is highly correlated with actual building performance.
Research from Germany bears this out. Data from independent researchers, shared by Passivhaus Institut, compares the heat consumption of four developments: three Passive House settlements and one non-Passive House settlement (though still fairly energy efficient.) Their findings:
- Passive House radically outperforms conventional energy-efficient buildings, by up to 80 percent in heat consumption.
- Occupant behavior varies widely. It is normal to see a swing in energy use of around 50 percent for identical units within a settlement. The S-curves that emerge for each development illustrate the variance between energy “misers” and energy “hogs” across functionally identical units within a community.
- Passive House modeling has strong predictive power. The PHPP model’s predicted heating consumption for the three Passive House settlements is nearly identical to the actual average heating consumption of each.
Passive House models are highly correlated with actual building energy performance for two reasons.
First, the data inputs for the PHPP performance model exactly correspond to the actual building materials and assemblies used in a Passive House project. And these assemblies control convection, conduction, radiation, and the movement of heat, air and moisture.
Second, Passive House quiets the volatility (measured in temperature deltas, moisture gradients and air leakage rates) that we see in non-Passive House buildings. Energy models of stable systems are more accurate than energy models of volatile ones. So, the quiet and comfortable interior environment in a Passive House is a boon for both the occupant and the modeler.
The key design breakthroughs of Passive House center on the skeleton, skin and respiratory system of buildings.
For centuries we have ignored the thermal (and condensation) implications of the structural elements of our buildings, blithely allowing beams to jut through walls without a care for the energy transferred through these thermal bridges. In fact, steel beams thrusting through otherwise decent exterior walls can still be seen as a signature architectural gesture today.
But even far less egregious examples of thermal bridging, like wood studs in a wall, dramatically reduce the overall performance of the building envelope.
If not detailed properly with thermal breaks between inside and outside, the skeleton of a building can undermine energy performance, yet thermal bridging is either ignored or incompletely accounted for by many modeling protocols and by many designers.
Passive House is the gold standard of thermal bridge-free design, dramatically improving energy performance, predictably.
SKIN AND RESPIRATORY SYSTEM
In a Passive House, building envelope and ventilation function together as a system. Airtight construction is central to this system because it limits the movement of air, and the heat and moisture that air carries, through the building envelope. This dramatically reduces the loss of thermal energy from buildings, especially when combined with a thick sweater of insulation. It also protects the integrity of building assemblies, limiting the movement of moisture into wall cavities where it can cause mold and rot.
Equally important are the health implications of this approach. Airtight construction stops random, uncontrolled air leaks through cracks in building materials and enables designers to bring filtered fresh air in through balanced ventilation with heat recovery. This approach delivers superior indoor air quality to building interiors. (This is why the 2017 Washington Code will require DOAS, or Dedicated Outdoor Air Systems, in commercial buildings.)
The heat recovery of ventilation air brings major energy performance benefits as well. And because the airtight envelope eliminates random air and heat leaks, the system becomes easier to model: predictable energy performance.
At what cost?
I’m often asked, what does Passive House cost? What’s the premium?
It really depends on the building typology and program, of course. And if Passive House is tacked on late in project development as an afterthought it can be expensive. But when part of an integrated design approach, Passive House’s “premium” can be negligible.
Recently released data from the Pennsylvania Housing Finance Agency illustrates the point. In 2015 and 2016, the agency received 179 project proposals for Low Income Housing Tax Credits: 59 of those proposals were for Passive House projects and 120 were for conventional buildings. The average projected construction cost for the Passive House buildings was $171/square foot, compared to $168/square foot for the conventional projects. That’s a difference of just 1.8 percent.
Revolutionary efficiency, predictable performance and negligible cost premium? That sounds like a pathway to move our industry from being part of the climate problem to being part of the climate solution. And not a moment too soon.

Photo by Casey Braunger: Orchards at Orenco, near Portland, applied lessons learned from phase one to slash the Passive House expense in phase two by more than half. This fast learning curve makes Passive House a great candidate for incentive programs aimed at market transformation. Ankrom Moisan and Walsh Construction led the team.
When I bought my Prius in 2010, the federal tax rebate for hybrid vehicles was a real win-win. The feds got one step closer to their fuel efficiency goals and I got my hands on an uber-efficient vehicle without breaking the bank.
The approach was simple: incentivize the purchase of a superior-performing product.
But imagine if that incentive had been structured differently. What if it depended on user behavior? What if I could be penalized later if my driving habits led to greater-than-modeled fuel use? Too many trips to the mountains? Foot too heavy on the gas pedal?
With the risk of such a penalty, I wouldn’t have purchased the Prius. I doubt others would have either. The risk of that behavior-based penalty would have weakened the incentive’s power to motivate buyers to purchase hybrids, slowing adoption.
The certainty of Prius performance means that policymakers don’t have to impose such a penalty. The fuel efficiency of a 2016 Prius is carefully measured and known (VW cheating notwithstanding), and each Prius that comes off the assembly line will perform essentially identically to the one before it. Regardless of driver behavior, more Priuses means increased fuel economy on aggregate.
But that kind of certainty has been lacking for green buildings. Unlike cars, every custom-designed building is a prototype, totally unique. Even for designs that are replicated over and over, each building will vary in orientation, shading, solar access, elevation and construction quality. And frankly, conventional means of predicting building energy performance, even LEED-certified ones, has seemed little better than guesswork at times.
The rational decision for policymakers crafting building efficiency incentives has been to require post-occupancy energy monitoring and to impose penalties when actual performance doesn’t perform up to snuff.
While this approach removes uncertainty for policymakers, it creates it for project owners. The risk of financial penalty is a disincentive.
Passive House design can remove uncertainty for both policymakers and project owners. Its energy modeling is predictive, with modeled results highly correlated with actual energy use. This correlation is thoroughly documented and demonstrated thousands of times over in the U.S., Europe, China and elsewhere.
This certainty means that, like the Prius incentive, we can incentivize better buildings with all carrot and no stick because both policymakers and project owners know that they’ll get superior energy performance at project completion.

Driving costs down
Make no mistake, the stakes are high for getting catalysts for change right.
Most of us recognize that climate change represents a serious threat. We understand that humanity needs to rapidly change the way we use and produce energy. This is why Seattle’s Climate Action Plan calls for net zero greenhouse gas (GHG) emissions by 2050, and King County calls for an 80 percent reduction by the same date.
Real cause for climate hope has emerged recently. The plummeting price of renewable energy, batteries and electric vehicles makes meaningful GHG reductions doable. Financial analysts from Citi, Bloomberg New Energy Finance and Alliance Bernstein argue that because solar, wind and EVs are powered by technology, innovation will continue to drive costs down. This cost shift is causing a fundamental and increasingly disruptive transition away from “business as usual.”
The key question is whether that transition will happen quickly enough to achieve climate security.
Answering this question rests in large part on what we do with our buildings. Buildings consume nearly half of all energy in the U.S., and are responsible for over a third of GHG emissions in King County. Viewed through the lens of climate change, buildings are a problem.
But buildings could readily become part of the solution. Just as cheap renewable energy, batteries and EVs are changing the rules of the climate change game and making climate action practical, so too can Passive House design.
The genius of the Passive House approach is that it views the building itself — its skeleton and skin — as a technology. Innovation can therefore drive down both energy demand and the cost of meeting that demand. Passive House buildings routinely use 90 percent less heating energy than conventional buildings, and up to 75 percent less total energy.
When a project team does its first Passive House building, construction tends to cost a bit more, but the learning curve is short. By the second or third project this cost premium often drops 2-3 percent on multifamily and commercial buildings. When you factor in superior building quality, better comfort, indoor air quality and lower utility bills, this small cost premium leverages a lot of value in terms of higher rents, and lower vacancies and maintenance costs.
Passive House is scalable because it pencils. Other jurisdictions in North America recognize this and have begun to harness Passive House to deliver on both climate action and affordable housing goals, recognizing that low energy bills mean reduced energy poverty for building residents:
- The New York Energy Research and Development Authority made Passive House the centerpiece of its $27 million incentive for building energy efficiency.
- The Pennsylvania Housing Finance Agency uses Passive House performance as a key criterion for the award of Low Income Housing Tax Credits, spurring dozens of affordable multifamily Passive House projects throughout the state. Ohio, New Jersey, New York, Massachusetts, Rhode Island, Illinois, Connecticut, New Hampshire and Idaho have followed suit.
- The newly adopted Zero Emissions Building Plan of the city of Vancouver, British Columbia, positions Passive House design and construction as the model for future building in the city. The Vancouver Affordable Housing Authority is a big proponent.
It is time for the Seattle region to reclaim its position of national leadership in green building. The city’s Living Building pilot program is a great step. The next step is to scale up: capitalize on the predictive modeling of Passive House to create a catalyst that is all carrot and no stick, providing policymakers and developers with the certainty they need to make green projects happen and building-as-climate-action to scale.
To this end we are working with Passive House Northwest and others on the 20 by 2020 Building Catalyst, a campaign to reward buildings over 20,000 square feet that achieve 20 EUI (energy use intensity) by the year 2020.

Our friend and colleague Tim McDonald (pictured above) explains to a North American Passive House Conference tour group about how Pennsylvania Housing Finance Agency’s priority on Passive House for affordable housing projects is catalyzing innovative multifamily buildings like The Whitehall (under construction).
As Seattle gets ready to deliver 20,000 units of new affordable housing, we should ask if it can deliver the kind of high-quality, energy-efficient and low-maintenance housing that everyone deserves.
Most of the new affordable housing in Seattle will be underwritten with both state Low Income Housing Tax Credits (LIHTC) and the soon-to-be-implemented city of Seattle linkage fees.
These funding agencies, being strong proponents of social justice, should take note of recent successful affordable housing projects in Pennsylvania, which have been able to provide high-quality, healthy housing within state affordable-housing budgets.
Three years ago, Pennsylvania wanted to find a way to improve energy efficiency and construction quality in state-funded affordable housing projects, and landed on the “passive house” standard as the mechanism for achieving their desired gains.
Passive house refers to a voluntary standard of building design that reduces energy used for heating and cooling by up to 90 percent over code-minimum buildings. The passive house design methods of air-and-weather barriers, superinsulation and heat-recovery ventilation also create very healthy indoor air environments and reduce risk of rot and mold in buildings.
A year later the Pennsylvania Housing Finance Agency implemented an incentive program that included passive house energy benchmarks in its LIHTC application scoring. Their belief was that competition for state funds from nonprofit affordable housing developers would drive lower-energy, higher-quality projects.
This affordable passive house project in Philadelphia received funding from a nonprofit agency.
In the first year, 20 percent of all awarded affordable housing projects in Pennsylvania were built to the passive house standard, which will result in 422 new high-performance affordable housing units. In the 2015 funding cycle, almost half of all proposed projects chose to pursue the standard.
Other states with affordable housing funding agencies have taken note, and currently nine other states, including New York, New Jersey, Ohio, Rhode Island, Massachusetts, Illinois, Connecticut, New Hampshire and Idaho, have included the passive house standard as an incentive in their own affordable housing funding selection criteria.
Affordable housing developments are well suited to being high-performance passive house buildings for many reasons.
The first reason is that passive house buildings are much more efficient to heat and cool than conventional buildings, which lowers operating costs. Lower operating costs are very important for affordable-housing operators because rents are lower than market rate average, and they must keep operating costs in check to remain viable.
In fact, because electricity costs are rising faster than rents in many areas throughout the U.S., passive house buildings confer additional long-term financial viability to multifamily housing assets, often referred to as “future-proofing.”
The second reason that affordable housing developments are well suited to being passive house is that maintenance costs are lower. This derives from the air- and weather-tight exterior walls and roof, which prevent water intrusion as well as in-wall vapor condensation, eliminating the chances for rot and mold. Longer exterior system replacement schedules translates into lower reserve funds, and therefore lower operational costs.
Third, passive house interior spaces are much healthier than conventional buildings, which is just as important for affordable housing residents as it is to any other individual or family.
We believe that everyone should have access to safe, healthy, affordable homes. Spaces are more comfortable because the passive house enclosure and HVAC system keeps thermal and humidity swings within the human comfort range, and because the heat-recovery ventilation system used in passive house buildings provides constant, HEPA-filtered fresh air.
Lastly, apartments are more peaceful because continuous exterior insulation and high-quality windows and doors keep outside noise and odors away.
Need for state incentives
In Seattle, multifamily affordable housing buildings use significantly more energy than their market-rate counterparts across building sizes, according to the Seattle Office of Sustainability & Environment.
This has often been attributed to lower unit sizes and denser populations in affordable housing facilities. However, in the case of mid-rise buildings, the affordable housing facilities are on average 28 percent more dense, yet use 42 percent more energy, which cannot be attributed to population habits alone.
If the passive house standard is incentivized at our state and local levels, it would be reasonable to expect — following Pennsylvania’s experience — that after four years, half of our new affordable housing stock would be performing at 18 EUI, or a full two-thirds less energy than was benchmarked in 2013.
We’ll need to build 8,000 units in four years’ time to stay on pace with the mayor’s housing challenge of 20,000 affordable units within 10 years. With a Pennsylvania-type passive house incentive system, at least half of the 8,000 units would be low-energy, low-operating cost, comfortable and healthy places to live for our community’s needy individuals and families.
The time is now to incentivize high-performance affordable housing in new construction, not later when we will have to go back and retrofit walls, roofs and foundations.
Seattle has long been seen as a progressive city when it comes to social and environmental justice. If we don’t adopt now what other states rightly see as a clearly progressive initiative to build quality affordable housing, then we will not even be able to call ourselves sensible followers, much less leaders, in the social and environmental justice movement.

I’m new at NK, drawn here by the firm’s commitment to design and building performance. Call it “Passivhaus high design.” So it was fitting that just three weeks into my new job I got the chance to be part of a weeklong Certified Passive House Designer training with all of NK’s Seattle architectural staff. It was an immersion in both the building science of Passivhaus and in the community of designers that is NK. (It’s an inspiring group, as I think you’ll get a sense for from the quotes later in this post.)
The inimitable Tomas O’Leary – Irish Passivhaus pioneer, instructor extraordinaire, cofounder of Passive House Academy, and all-around sparkplug – taught the training. The man has a gift, holding the 35 of us mostly-rapt for five long days of training in Passivhaus design principles, building science fundamentals, component performance calculation, and PHPP modeling minutiae.
The training was a big deal for us. We aim to be a national leader in Passivhaus design, especially for multifamily and commercial buildings, so growing our firm-wide Passivhaus capabilities is mission critical. We will likely soon have more certified Passivhaus professionals on staff than any architectural firm in the US, but more important than that distinction is the multiplying effect that group training brings. Passivhaus won’t be something that one or two isolated designers try to carry forward at NK. We all get it. We’re all aware of the ways that Passivhaus planning and building science can support great design and better buildings.
“I’ve been in architecture for over 25 years, and to me, the Passivhaus method of designing buildings is really the top of the game,” said Tim Weyand, NK’s CEO. “It’s surprising that Passivhaus hasn’t already caught on in the United States. I mean this is such an accepted way of building, entrenched in Europe and getting to be that way in areas of China, actually. For this way of building to totally reduce the amount of energy that we use in our built environment and not to be embraced already is weird. I think it’s going to take off, and we’re right there, so I’m excited about that.”
This Passivhaus perspective is attracting new talent to NK.
“When I found out that NK was offering Passivhaus training to its designers, that actually made me choose this job over other jobs,” project manager Peggy Heim told me. “I had been interested in Passivhaus for a long time, and I wanted to have the training. But I wanted to have the training as part of a group so that we could support each other. Because if I just got it on my own I wouldn’t necessarily have the projects or people to collaborate with so I would be just kind of figuring it out on my own.”
One of the big draws of Passivhaus is that unlike other green building certifications like LEED or Built Green, it requires revolutionary gains in building energy performance. Climate change is humanity’s most pressing environmental crisis and buildings are responsible for nearly half of our greenhouse gas emissions. The idea that building and renovating can be a form of climate action is exciting, and Passivhaus arguably delivers on this promise better than any other design approach.
“When I graduated about ten years ago from architecture school, LEED and sustainable building practices were taking off,” Peggy said. “I was initially really excited about that, but I feel like those types of projects don’t go far enough. I think they were good in starting the conversation, but Passivhaus takes it to the next level. There is a path to really reduce our carbon footprint through these types of buildings.”
Project architect Alyse Zimmer also points out the health implications of Passivhaus design.
“When I first started working in the architecture industry, the first homes I worked on were Built Green 4-star or 5-star,” Alyse said. “It felt good that I had some sort of impact. It was better than code mandated buildings. But what we could have done through Passivhaus would have been so much more.”
“Looking back at my motivations for going into the architecture field, I wanted to be able to create something that’s beautiful and wonderful for a homeowner 50 or 100 years down the line,” Alyse continued. “Passivhaus actually incorporates health into that. That’s huge. When I think of an unhealthy building, if that were something that I created, that would be horrible. To be able to incorporate Passivhaus techniques so that the occupant is healthy and it’s a beautiful building? It’s really awesome.”
Beautiful buildings that promote the health of occupants and the planet. Shouldn’t that be what we all strive to design? The approach is not complex. The modeling tools for Passivhaus are built on advanced building science and formulae, but the design approach is one of simplicity.
“I’m impressed with the basic simplicity of the Passivhaus system,” said senior technical architect Loren Brandford. “There’s a very short list of rules which are usable to drive design towards very large energy savings and more ‘moral buildings,’ or less ‘immoral buildings,’ as Tomas put it.”
For Loren, the desire to create “moral buildings” goes back to ninth grade bible class.
“Mr. Merrill made us read ‘The Limits To Growth,’ the report of the Club of Rome. And I admit, it sort of scared the bejeezus out of me,” Loren said. “Oh my god, we’re going to run out of iron ore! We’re going to run out of aluminum! We’re going to run out of gravel! We’re going to run out of oxygen! We’re going to run out of oil! That put me on the course of thinking about issues of sustainability, as it did for many people.”
This ultimately drove Loren to architecture as a profession.
“When it came time to choose a career, what I was going to do for the rest of my life,” Loren continued, “having lived in apartments most of my life, and lived in cities all my life, and being concerned with issues of sustainability, I sort of smashed them all together and aimed toward sustainable housing in cities. You can draw a ridiculously straight line between what brought me to architecture initially and Passivhaus design as a rigorous system for building sustainably on this Earth.”
Staff architect Brittany Porter’s story echoes Loren’s.
“I decided to become an architect not knowing whether I should become an environmental lawyer or a politician or who knows what,” Brittany explained, “trying to do something towards sustainability and towards improving our global future. Passivhaus is an amazing tool to do that. It’s a tool to try and build more responsibly.”
The training with Tomas had an immediate impact on Brittany’s work.
“The day after we got back to the office after the training we were working with our SIPs [Structural Insulated Panels] manufacturer,” Brittany said, “and we were able to bring drawings that we had done at the training during lunch breaks and asked, ‘Can you do this? Can this be manufactured for us?’ And they can! So we were able to achieve the airtightness that we talked about at the training and also the continuous insulation using this new material, this new piece of construction. We said, ‘We learned these principles, can you help us do this thing?’”
“They were a little surprised,” Brittany continued. “They hadn’t realized that, ‘Oh if we just inset a window in the sill that one inch and bring that insulation up it’s going to be the detail that achieves Passivhaus.’ That was really exciting, and it happened 24 hours after the training.”
The most consistent reaction to the training? Praise of Tomas and his teaching style.
“What was the highlight of the training? Tomas O’Leary. He was just…I can’t get him out of my mind! That sounds creepy,” joked principal Jill Burdeen. “I can’t imagine having taken that class from anyone else. There was no part of it, no matter how mundane, when I wasn’t captivated. He was so engaging. Engaging! That’s the number one word I use for him.”
“The real highlight of the training was Tomas’ boundless energy and enthusiasm for the Passivhaus system and conveying what he understands of it to the rest of us,” Loren agreed. “We were eager to learn it and he was eager to share it, despite many, many time zones of difference and very long days.”

Change is afoot in the world of building design. Both our ability to design buildings that address climate change and our sense of urgency to do so are stronger today than ever.
The Passive House approach to high performance building stands at the vanguard of this development, enabling designers and builders to revolutionize building energy performance in a scalable and cost-effective way: buildings can become a form of climate action.
As we wrote recently in our post about our experience at the North American Passive House Network’s conference in New York City, serious momentum for Passive House is building. We’re committed to help drive that momentum and to help provide the building science expertise necessary to create projects that realize the full potential of the Passive House approach – not only transformative energy efficiency, but also superior comfort, indoor air quality, and building durability.
To that end, we’ve brought to Seattle one of the world’s leading Passive House trainers, Tomas O’Leary, for a five-day “deep dive” into Passive House building science and energy modeling. All Seattle NK design staff – 34 in all – will take part in 55 hours of top-level this week. (NK Pittsburgh staff will go through the same training this September.)
Tomas is co-founder and president of Ireland-based Passive House Academy, the Passive House certifier whose certification portfolio includes the Cornell Dormitory Tower on Roosevelt Island in NYC, the world’s tallest Passive House building. Tomas and PHA also cracked the code in Ireland’s Dún Laoghaire-Rathdown County to require all new homes to be Passive House. He’s an entertaining and high-endurance educator (which will surely come in handy during his five intensive days with us!).
With this training under our belts the next step will be to study and prepare for the examination process to become Certified Passive House Designers. That exam will take place in October.
If you’d like to meet Tomas and hear from NK designers about how the training is going, please join us this Thursday evening (7/21) from 5-7pm at the FADO Irish Pub’s “Dungeon Room,” 801 1st Ave (near Pioneer Square), for an evening of drinks and conversation.
In the meantime, wish us luck as we hit the books!

The talent and unique perspective of our staff is at the heart of every project we design. Each quarter we will highlight a member of our team in Four Questions with NK, a series intended for our clients, partners and peers to get to know NK Architects a little better. This month, meet Curtis Bigelow, a project manager with a passion for thoughtfully designed urban landscapes and pushing ultra-sustainability forward.
What industry changes are you are most excited about?
The most exciting shift in the industry, to me, has been the rediscovery of urban neighborhoods. Sadly, so many of our western cities were deserted 60 years ago and the infrastructure turned to suburbia – creating dissociated neighbors, horrible traffic, wasted farmland, and ugly landscapes. Recently, people are coming back to the cities and architects are embracing the concepts of urban living: exploring different building types, materials, and connections. Integrating energy efficient concepts and urban building is exciting and worthwhile. Creating interesting buildings on small, infill sites is a test in itself, but the complexities of the added desires of the modern world and environmental responsibility add to that challenge. The demand on our profession seems to be: make successful, attractive, sustainable buildings that add to our sense of place, allow for the human experience, and provide a legacy for the future. How much more exciting is that?
What does great design mean to you?
Great design is a successful design. Success is measured from the owner’s pocketbook and the user delight from the first day. It’s also reflected in a project’s longevity. As someone who strongly believes our society needs to make some basic changes to our built environment concerning energy use, energy consumption, and urban life, buildings, infrastructure, and landscapes need to contribute unequivocally to the healthy, vibrant, happy lives of people. Great design incorporates the needs of today while staying flexible for the future and encourage good decisions. Great design enhances and eases individual, daily activity while contributing to a vibrant, efficient city. Great design synthesizes all these things beautifully and cohesively to support surroundings that people cherish.
What do you like most about Seattle’s architecture?
For me, the best part is its accessibility, and of course, its sense of Seattle. Growing up in the Pacific Northwest, I have a connection to the rainy, wooded forests of western Washington and the natural beauty that can be seen all around the region. The great buildings of Seattle draw from that expression and reflect the imagery and grandeur of our exciting landscape as well as the spirit of the people who live here. The singularly white and tall spire of the Smith Tower reminds me of the white capped mountains throughout the Cascades and the fading brick of the Seattle Tower harken back to the rocky shores along the Sound. Seattle also loves something unique and new; our city symbol, the Space Needle, is just plain futuristic cool and the growth and variety of downtown’s contemporary buildings reflect the region’s desire to live in a vibrant city.
Seattle’s architecture feels pedestrian – in the best possible way: it isn’t too high brow and generally gives a person the chance to appreciate either a special detail, like the Arctic Building’s tusks, or a sparkling window that opens onto one of our neighborhood corridors allowing the energy of the interior to erase the line between inside and outside. Pacific Northwest architecture has long relied on blurring the lines of the natural and built environment, keeping us rooted to our surroundings.
What style architecture are you most drawn to?
In a word: quirky. I’ve never been one to design ‘star’ buildings; my buildings tend to be part of the fabric of a neighborhood or environment. Perhaps that is why I find those little gems of construction or thought so compelling. I find that something unexpected or a small, but bold creates a delight that is more personal and special. I do try to incorporate some small, focused item of interest or unusual design decision that has a very specific reason or function. The small scale of a quirk is what draws my attention and helps bring a connection between the built environment and the human experience through identity and care.

Earlier this month, NK’s founding principal, Brandon Nicholson, and CEO, Tim Weyand, attended the North American Passive House Network (NAPHN) annual conference in New York City. NAPHN brings together owners, designers, builders, suppliers, lenders, enthusiasts, and policy makers who want to learn about the latest techniques, innovations, and policy changes affecting the industry. It’s also the time when board members of NAPHN network organizations, including Passive House Northwest and Passive House of Western Pennsylvania, convene to set the annual NAPHN agenda.
One of the most important takeaways of the conference is that Passive House is accelerating in the US, particularly in the Northeast and Northwest—a great opportunity for our firm and those individuals and organizations with Passive House experience and focused expertise.
We also gained an understanding of key policy changes and commitments that will shape the continued growth of this important movement to achieve a carbon neutral future.
- New York City has committed to reducing citywide greenhouse gas (GHG) emissions by 80% by 2050 – the 80/50 Initiative. In NYC, buildings account for 73% of their GHG’s and the City has committed to a 50% energy reduction for all new municipal buildings starting now, and codifying a whole-building performance standard by 2022.
- The New York State Energy Development and Research Agency’s (NYSERDA) Deep Energy Retrofit Program is targeting Passive House as a method to retrofit 100,000 units of affordable housing by 2025.
- 422 new units of affordable housing being built today in Pennsylvania with PA Housing Finance Authority (PHFA) tax credits, will serve as a catalyst for thousands more in another 10 states with similar programs. Washington State is being lobbied hard to include Passive House in their Qualified Allocation Plan.
- Vancouver B.C. has committed to being carbon-free by 2020 and sees Passive House as a proven method to reduce overall energy demand. The City of Vancouver has trained several key staff members, including the Director of Build Inspections, in the 5-day Passive House Tradespeople program, and plan to train another 40 in one-day sessions. The department is actively changing their code to remove barriers to Passive House design.
Member organizations, including Passive House Northwest, are taking note of these important strides towards carbon neutrality in NY, Vancouver and Pennsylvania, and will be advocating hard in their regions for similar advances.

NK Architects will design Gerrish Hall, an eight-story boutique apartment project in the heart of Capitol Hill at 1820 Boylston Ave. Developed by Capitol Hill Lofts, LLC, the 55-unit 43,270 sf project will be comprised of one-and-two-bedrooms, a guest suite, and two penthouse units with views. NK’s design will capitalize on its central location with added stories, including a recessed top floor that creates space for a common rooftop amenity area while offering quiet and privacy from the street.
The well-designed units will have a large sliding door system that opens to private balconies to create synergistic indoor/outdoor living environments. Each unit will also feature interior glass walls separating the bedroom from the living area while allowing for an abundance of light throughout. Penthouse units will have a large kitchen, separate living area, master suite, and one with access to a private rooftop deck. Residents will enjoy an indoor/outdoor amenity room with a large screen TV, and a kitchen with La Cantina folding doors that open to large rooftop deck with a fire pit and sweeping views of downtown Seattle, Puget Sound, Space Needle, and Queen Anne.
Located just two blocks from the Broadway corridor and Capitol Hill’s newly opened light rail station, residents will enjoy a Walk Score of 98 with easy access to downtown, South Lake Union, acclaimed restaurants, and nightlife.
Gerrish Hall will be designed to Built Green 4-star certification. Construction is scheduled to begin winter 2016.
