Risk is real in the AEC. True risk management isn't about avoidance, but about informed engagement.Homes and buildings today measure success in many ways, each of these represent a potential failure mode. Managing risk means recognizing and embracing it, this is a core message from our guest today. Joe Basham is a seasoned construction industry attorney with decades of experience, a keen mind, clever wit and the ability to cut to the heart of the matter.

Join Kristof and Joe as they delve into the critical role of risk management in the design and construction process and unpack real world ways to navigate challenges with demanding clients, the importance of clear contracts, the power of proactive project management. The discussion also focuses on the impact of new project delivery methods, the rising costs of professional liability insurance and evolving liability concerns in the larger context. Discover how architects are adapting by focusing on design leadership, leveraging consultants, clear contract language and the importance of having open and respectful relationships with all stakeholders. 

We explore the arriving potential of AI to revolutionize the design profession, offering increased efficiency and informed decision-making - recognizing that this is also a deep change and one that comes with implicit risks and rewards. 

One final thought is that the ultimate de-risking move is to design thoughtfully, build carefully and maintain open communication and realistic expectations at all times!

Understanding climate action through the words we use

Keep an ear out for an easter egg after the outro on this one.

The words we use matter. Terms like "sustainability”, “net zero” and “resilience” signify our industry's evolving priorities and concerns. These “buzzwords” reflect current cultural circumstances within the AEC industry and larger society while also actively shaping how we approach and address these issues. 

In this episode will be exploring the meanings and relationships between many of the current buzzwords that are alive in the AEC today. If you’ve ever wanted to deepen your understanding of words and terms like “sustainability”, “net zero”, “embodied carbon”, “circular economy”, “resilience” or “adaptation” you’ll appreciate this interview w/ Kjell Anderson of LMN Architecture in Seattle.

Yes, buzzwords come and go. We routinely air quote them somewhat irreverently. But do not be fooled - buzzwords are also important. Far from being superficial, these trends in language mark the emergence, acceptance, and eventual integration of new, often significant, ideas. When a word gains prominence, it often signals a collective reckoning with the issue it represents. Conversely, when it fades, it may indicate that the idea has either been absorbed into the mainstream, superseded by more urgent concerns, or—sometimes quite worryingly—been deprioritized.

Dictionary definition of “Buzzword”:  (pejorative) A word drawn from or imitative of technical jargon, and often rendered meaningless and fashionable through abuse by non-technical persons in a seeming show of familiarity with the subject.

“The world is not made of atoms, the world is made of stories”

Muriel Rukeyser

“Where do buildings come from?” is a question that comes with a story. Less often asked, “Where do buildings go?”.  The evolving story human society tells itself in answer to those questions is worth unpacking thoughtfully. That’s what happens in this episode. Join Kristof as he shares a conversation with Greg Esparza on the power of storytelling and the connection between stories and the materiality of buildings. The power of storytelling is clear in the ability to connect people, foster empathy, and transmit knowledge and shape cultural values. The materiality of buildings is itself a response to storytelling. 

Every building belies the presence of an underlying story about our relationship with nature. At every step of the design and construction process we make decisions. What are those decisions based on? Unfortunately the answer is not often evident and is likely tangled up in outdated ideas based on stories that no longer make sense. The importance of biogenic building materials as an emerging theme in the AEC is not just their materiality, it’s deeper. It is the story of us all coming to our senses - both literally and figuratively - our senses of sight (of course), sounds, smells, and textures - while also thinking about where buildings come from and where buildings go. 

Ultimately the choices we make in how we deliver homes to ourselves impacts our felt sense of life altogether. Why not curate materials for our homes that actually make us feel good? Turns out when we do this we find that these same decisions support the AEC’s ultimate triple bottom line of healthy homes, healthy people, healthy planet.

Greg Eparza

Greg Esparza is a designer and builder with over a decade of experience in custom residential design and construction as a co-founder of Moontower Design Build in Austin, TX. In 2021, Greg immersed himself in designing and building a prototype project called Cross Cabin, a “plant-based” home made of hemp, cork, and cross-laminated timber for himself and his family in Austin. Inspired by this experience. Greg established Cross Cabin Build & Supply to represent and distribute healthy, high-performance, and low-carbon building materials in Texas. Greg has a passion for building with natural, plant-based materials rooted in the commitment of the AIA Architecture & Design Materials Pledge to support health at three scales–human, social, ecosystem–and to prioritize climate impact and circular economy considerations with all material specifications. The Cross Cabin has been featured on the Build Show Network, Dwell+, Passive House Accelerator, The Architect’s Newspaper, as well as the 2023 AIA Austin Homes Tour where the most frequent feedback on the home was “I love the smell!”.

The tension between aesthetics and performance in architecture is a critical and complex issue in contemporary design. Architects are increasingly and appropriately being tasked with designing buildings that are not only beautiful but also functional in terms of impacts on owners, occupants, resources, and planetary ecosystems. The contrasting view, one where architecture is principally form-making comes at its peril. As Juhani Pallasmaa cautions, following this path  “The world becomes a hedonistic but meaningless visual journey”

Navigating the path between form and function is central to the role of architecture in our society. It is also the backdrop to the daily routine for our guest in this episode. Keith Simon FAIA is both an architect and an enclosure consultant, two roles that move him from one vantage point to the other continually.

As Keith says in this interview Architects could be leading many of the changes society needs now but are not. I think we should all look introspectively and ask “Am I prioritizing the right things?”. This episode is both a tribute to the importance of architecture and an appeal to prioritize the lived experience of homes and buildings over the hedonic sculpture on the cover of the glossy magazine. The themes touched on here will ripple out through the AEC for the rest of our careers. It’s both important and captivating to reflect on them now. Enjoy!

Join Kristof and Corey Squire in this third and final installment of their interview series discussing Corey’s book People Planet Design. In Part 1, they opened the discussion at the logical starting place of the important Why questions. Why design matters to society and Why architecture is the place to address so many important issues we face today. Part 2 addressed How to make good design happen by focusing on often overlooked dimensions of the design process. These include company culture, communication and information flow, and the importance of positive incentives.

Here in Part 3 is where the rubber meets the road in the form of the What question - What types of systems do we actually design? What do we actually do during the design process? This conversation flows across ten different architectural systems that each correspond to a chapter in Corey’s book. The systems covered are (1) Scale; (2) Windows; (3) Air; (4) Roof; (5) Electricity; (6) Structure; (7) Embodied Energy/Carbon; (8) Interior Finishes; (9) User Behavior, and (10) Access/Equity.

People, Planet, Design: A Practical Guide to Realizing Architecture’s Potential

If you were asked to close your eyes and envision where you are happiest, would you picture somewhere inside a building? North Americans are inside buildings for more than 90% of the day. Meanwhile, the indoors are stifling us, sometimes even killing us. Buildings, and the materials that make them up, expose us to materials linked to negative health impacts. The construction and operation of buildings is responsible for 40% of climate-changing carbon emissions. 

In the US, the design choices made by the typical architecture firm employee each year can reduce emissions by about 300 times that of an average American. But the promise of sustainable architecture will not be realized if sustainability remains a secondary consideration for architects. What if great design were defined by its ability to cool the planet, heal communities, enhance ecological functioning, and advance justice?

In People, Planet, Design, architect Corey Squire builds the case, provides the data, and lays out the practical tools for a transformative human-centered architecture. This approach integrates beauty and delight with an awareness of how every design choice impacts the community, the planet, and the people who will use the building. Outcome-focused with a deep dive into practical design strategies, the book showcases ten building systems that embody design excellence.

Squire centers the idea that by focusing on the desired outcomes—that buildings shelter us from the elements without disconnecting us from the world, that buildings provide the quality of air, light, and views we now know to be essential to health, productivity, and joy—we can move beyond the checklist mentality that has captured much of the design community.

Essential reading for architects who want to transform what the profession means, People, Planet, Design pioneers a new vision and sets readers up with clear guidance on implementing it. Only when design prioritizes people, as it should, can architecture realize its full potential.

What is the future of dehumidification? Turns out this simple question opens up an exciting view of the future of IAQ generally. The goal of a low energy method for removing water molecules from a flowing airstream boils down to some way of identifying, grabbing and holding onto them. Essentially we are talking about a designer desiccant or molecular filter that lets the air pass through while it filters out water molecules. 

If we can do this, the next logical question is “Why stop there?” Why not identify a broad range of pollutants and contaminants in the airstream and also select and remove them as well? 

Enter molecularly sensitive filtration based on Metal Oxide Framework (MOF) technology. MOFs are a type of advanced material that scientists are developing to tackle a wide range of challenges, from clean energy, to environmental protection via direct air carbon capture (DACC), to health and drug delivery.. While the name may sound complex, the basic idea behind MOFs is relatively simple—they are materials made by combining metal ions (like zinc, iron, or copper) with organic molecules to create a kind of 3D structure that is highly porous, meaning it has lots of tiny holes or cavities - and they operate as a molecular sieve or filter. 

Join Kristof as he interviews Todd DeMonte of Madison IAQ to unpack the future of dehumidification and learn about desiccants, and the potential for metal oxide frameworks. Along the way we learn whether the “good old” compressor-based dehumidifier is likely to remain the preferred and appropriate approach for many years to come. This is an episode that will bring you up to date at this important edge of the industry. Enjoy!

Passive house has become synonymous with the rapidly arriving new normal for our homes and buildings and offers layers of positive outcomes. Thermal comfort, IAQ/IEQ, durability, and low energy use are typically the incentives for owners, architects, builders and trades. As it turns out, there may be broader societal benefits tied to thoughtfully managing heat flows in and out of a building as well. Good ol’ thermodynamics isn’t getting the flashy attention of solar PV, wind turbines and batteries, but the demand side may well be where we win this fight to protect ourselves and our planet from the worst, most devastating impacts of the climate crisis.

Join Kristof in this wide-ranging conversation with Lisa White, the Co-Executive Director of Phius, where they unpack the positive ripple-out impacts that passive buildings have on our energy grids, and our decarbonization efforts. Seen holistically, buildings are a powerful enabling technology for the ongoing energy transition away from fossil fuels to renewable sources of energy. Starting with a perspective on the current state of the grid and its ongoing evolution, the conversation here positions passive buildings in relation to the decline of the fossil fuel era and the dominance of renewables.

Lisa White

Lisa White is the Co-Director and a technical lead for Phius.  

Ms. White has been with Phius since 2012. She led the building certification review team for seven years and is an instructor for Certified Passive House Consultant (CPHC®) training and WUFI® Passive energy modeling software training. She holds a degree in Environmental Sustainability with a minor in Architecture from the University of Illinois at Urbana-Champaign, and a Master’s in Energy Engineering from the University of Illinois at Chicago.

Ms. White has a strong understanding of high-performance building design and how this is integral to the transition to a renewable energy grid. Her Masters’ thesis posed the question “What do Net Zero Buildings Cost the Grid?”, combining the concepts behind how building loads are shaped, how design techniques can alter that shape, and how that ultimately impacts the electricity generation resources needed to meet the load – all while considering the shift to more intermittent, renewable energy resources. Ultimately, this research concludes that energy conservation and demand response in buildings is a critical up-front investment to facilitate this transition.

At Phius, White works on the development of new and existing professional training courses and has delivered professional training to more than 800 students. She has taught introductory and advanced seminars at professional conferences and universities nationwide, including guest lecturing at the Harvard Extension School. She is a longtime member of Phius’ technical committee and was instrumental in the development of the Phius+ 2015 Climate-Specific Passive Building standard, followed by the 2018 and 2021 updates. Alongside standards development and research, White works directly with the Fraunhofer Institute of Building Physics to develop and implement new key features into the WUFI Passive energy modeling software that Phius uses for passive building certification. While in her previous role as Certification Manager, Ms. White reviewed and provided feedback on energy models, drawings, details, planned mechanical systems, etc. to more than 500 project teams working on passive building designs across the world.

Ms. White has written and co-authored many publications, the most recent being a cover-featured article in the ASHRAE High Performing Buildings magazine. She has presented at numerous national and international conferences on topics related to grid-friendly buildings, assessing resiliency and passive survivability, measured data for high performance and net zero buildings.

Empowering the practice of architecture to achieve consistent, predictable, positive impacts on human well-being and planetary health is perhaps one of the most pressing topics in the AEC today. Starting with a review of the history of the search for Bioclimatic Law, this conversation with Dr Bill Braham, FAIA is an invitation to architects to reclaim their power. 

Bioclimatic Law is the relationship between architecture and life. In practice “life” is more narrowly defined by architecture as “comfort” or “comfort, health and well-being”. At its core bioclimatic design asks “What are the climate opportunities?”. The basic principle is to start with a clear understanding of the ambient climate and map those inputs to the design of the building - its massing, orientation, enclosure systems, and window sizes, locations, and shading devices. Beyond these truly passive methods, there are always active systems involved in maintaining a balance between heat flowing into the building and heat sources within the building.

Our buildings mediate between the external climate and our lives. From a thermal perspective, actively managing the enclosure can lead to comfortable indoor conditions 60-80% of the time in most climates. From a well being perspective, as the external climate becomes more unpredictable and severe we have an opportunity to improve the quality of the lived experience of the buildings we deliver to ourselves to protect and shelter us. Join Kristof as he and Bill enjoy a thoughtful, wide-ranging discussion about the role of architecture in society and the role of buildings as extensions of our lives and goals. 

Big picture, we also want to thank you for being listeners who, in our increasingly soundbite world, appreciate the depth, breadth and subtlety of conversations like this. We’re happy that you’re noticing and valuing that we “go there” in these idea exchanges. Please keep your emails and comments coming.

The work of the AEC is broader than buildings. On a daily basis we, collectively and individually, make decisions that have broad and lasting impacts on our lives, our health, and our world. These impacts can be either positive or negative; the choice is ours. This is the perspective of Gina Ciganik and her brilliant and motivated team at Habitable. 

Armed with powerful minds and compelling data, they are working to help society rethink material supply chains altogether. Formerly the Healthy Building Network, Habitable exists to help people understand that we need to fundamentally shift the materials economy to protect ourselves and our planet's ecosystems. These are also the people who created the Pharos database. Now they are releasing a powerful tool, The Informed Tool, to make it easy to make good decisions for materials using a simple Green, Yellow, Red system. It’s time to start.

If the term materials economy is somehow just a bit bland and doesn’t connect or feel engaging for you, consider these two facts to remind you of what we’re talking about:

1. Microplastics in the ocean: 58% of them are from one material - Paint. And 48% is from paint used in homes and buildings. We know latex gloves are plastic but somehow we forget that latex paint is as well. If we are going to ever get the plastics out of our waterways, oceans and bodies, we have to address this material and the upstream decision making process. 

2. Carpeting as single use material: 2 Millions Tons of carpeting are thrown into landfills and incinerators in the US every year. Our national obsession with fuzzy floors uses more plastic than all single use plastic bottles, plastic bags, and plastic straws combined (mic drop). 

OK, did those wake you up and help you understand that the decisions we make here in the AEC have implications and impacts far beyond what we normally consider our purview? Join Kristof and Gina in this lively wide ranging discussion as they unpack the work that Habitable is doing.

Gina Ciganik

Gina Ciganik is the CEO of Habitable and has been instrumental in growing and scaling the organization's vision since assuming the role in 2016.

Recognized nationally for her leadership in transforming human and environmental health, Gina’s strategic partnerships and innovative practices have reshaped housing standards across the affordable housing sector.
