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.

How can we build better supply chains for the built world?  When it comes to the inconceivably vast amount of wood we use in our buildings, one “simple” way is to use less virgin material and use more wood that would otherwise not make it to market. Instead it would be destined to decompose and emit its carbon into the sky. What if, instead, the forgotten trees were salvaged and turned into valuable, usable lumber?
This is a big idea whose time has come. Still, having a powerful idea is only the first step. Making it happen in the real world is the other side of the story. Starting with a focus on a smarter, more transparent wood supply chain, the ambitious team at Cambium Carbon are making powerful change happen in the human side of the wood ecosystem in the AEC. Their work is a key support for firms committed to sustainability. 
 Join Kristof in a thoughtful conversation with Ben Christensen to learn more about what Ben and his team are doing to find wood impacted by the four Ds: disease, decay, disaster, and development and keep it out of landfills. Instead of landfills the wood goes back into the built world for generations to come.

The company Living Carbon was mentioned during this episode as an interesting website to check out!

Ben Christensen

Ben, a Forbes 30 Under 30 lister and TedX speaker, is a thought-leader and industry expert. He is the CEO and Co-founder of Cambium, a climate-tech start-up backed by Joe Tsai, Steve Case, and many others. By working with cities to divert wood waste, local manufacturers to create sustainable products, and demand partners for offtake they are creating a new regenerative supply chain for urban wood. Ben loves to share his expertise on topics like circular economies, climate tech, leadership, and building teams. He earned his Masters of Environmental Management from the Yale School of Forestry and Environmental Studies.

Today we’re continuing the conversation on modular construction w/ Rommel Sulit and Chris Krager. Buckle up for some quotable quotes and impactful ideas in this episode. A recurring theme from part 1 is present here. Could it be the case that because modular delivery must rethink basic assumptions, it may be the first area of the AEC to do what the rest of the AEC is not. At core, the role of architecture is to create the link between design intent and what is actually built. This is not easy, nor simple. It means managing multiple streams of expertise and action so that they are effectively coordinated and integrated into a finished livable space.

Modular requires a high resolution understanding of why we build the way we do, what are its strengths and weaknesses, and, particularly, where are the key leverage points to unlock change. Because as they say in this episode, there’s no way around the reality that when it comes to AEC practices, We have to Pivot at somewhere. Modular delivery is perhaps, at heart, a recognition of this truth.

Rommel Sulit

Founding Principal and Chief Operations Officer at Forge Craft Architecture + Design. With 25 years of experience, Rommel founded Forge Craft with Scott Grinder to improve lives through the art and science of architecture and design. Rommel developed his architectural philosophy working on projects that span demographics, geographies and types at the Office of Metropolitan Architecture (OMA) with Rem Koolhaas, Page Southerland Page, Rhode Partners and BOKA Powell. 

Before Forge Craft, Rommel’s work in Europe and across the U.S. centered on ambitious, large scale urban developments. Rommel now oversees projects across Forge Craft’s six Architecture + Design Craft Studios including Commercial, Affordable Housing, Interior Architecture, Residential Use, Modular Architecture and Emergent Technologies.

Chris Krager

Chris Krager has a BA in Business Administration from Michigan State University, and he received his March First Professional from the University of Texas at Austin School of Architecture. Krager formed KRDB (Krager & Associates, Design/Build), a develop/design/build company, in 2001 with the intention of creating financially accessible architecture, while focusing on sustainability in the urban environment (www.krdb.com). The firm’s projects cover a broad range from single-family developments, small lot projects, mixed-use and multi-family developments, hotels, creative office, alternative senior living models, and more.

KRDB’s work has been recognized locally and nationally including winning the AIA Austin’s prestigious “Firm Achievement Award” in its first year (2001). Their work has appeared in the New York Times, Dwell, Architectural Record, Residential Architect, and Metropolitan Home amongst others. It has been published in numerous books including “Modern Shoestring: Contemporary Architecture on a Budget” by Susanna Sirefman, “Good House/Cheap House” by Kira Oblensky, “The Perfect $100,000 House” by Karrie Jacobs, and two of Sheri Koones’ “Pre-Fabulous” books. There work has also been featured on shows such as “This New House”, “Small Space, Big Style”, “Dream Builders”, “Dwell TV” and “What You Get For Your Money”.

KRDB’s Sol Austin project, a 40 unit model for holistic sustainable design, was one of the first net-zero capable projects in the US, and was awarded an AIA Austin Merit award, the inaugural Austin Green, “Project of the Year” and was featured on the front page of the NY Times Homes section (www.solaustin.com).

How often do you think about modular construction? Is it an idea whose time has come? There are those who view it as the only path forward that realistically checks all the boxes - are they right? 

The potential is clear, modular project delivery can save time, save money, and positively impact our current and looming labor and skills crunch on the construction side of the AEC. There is no doubt that relative to the current norm, the “holy triumvirate” of owner, architect builder*, modular delivery represents a disruptive force within the AEC. Modular may be exactly the solutions we need but also one that we are not currently embracing at scale. Why is that? What are the challenges and the opportunities for modular design, construction and delivery? Join us today to unpack those questions and more. 

Whether you’re a seasoned modular developer or just a curious newcomer and novice this podcast has something for you. Kristof is joined by Chris Krager and Rommel Sulit who, collectively have soaked up decades of experience and expertise in the modular space. One of the challenges to understanding modular design and construction is that it is dynamic and evolving. This confluence of financial, technical and material perspectives means different things at different times to different stakeholders. Along with our society and the AEC industry, modular has a path quality, it is not static, by some accounts where we are now is Gen 4 modular. To fulfill its potential modelar delivery needs to reach backward to influence the design process and also to reach forward to construction. This reality, while challenging, is long overdue and it is perhaps the most relevant and powerful benefit. It forces, or at least strongly encourages, the AEC to finally do integrated project design and delivery at scale.

Who knew that an indoor pickleball facility could become a touchstone for high performance construction based on passive house principles? The backstory here is worth unpacking as it relates to a powerful force that is not often discussed - money. Return on investment is the aim of the game in the realm of real estate investment and this fact typically filters out high performance passive buildings - but not this time, and it is important to understand why. Our guest today is adept in both the financial and the construction realms and has been able to make a solid case for the value of passive construction in his latest development. 

Beyond the financial angle, this project aim to showcase high quality construction while also fostering community through sport. Plus with the heat and humidity of the Texas summers playing sports indoors makes it far more accessible to people. Join us in this thought-filled interview with David Komet of Urban Earth to hear about his journey and learn what he’s doing with his new pickleball facility as he prioritizes the health of the community, the local environment, and the planet.

David Komet

David's professional career began with the Medical Center Guesthouse of America, developing interim stay facilities for patients and their families in major medical centers. From there he went on to be General Manager of Murdock Pharmaceuticals, a division of Nature's Way. His business experiences soon led him to the public capital markets and positions with Prudential Securities and Komet Asset Management managing private pools focused on long/short equity, direct lending and equity real estate investments. His current active projects reflect his deep interest in the sustainability conversation for the built environment, including age in place housing , commercial buildings and controlled environment agriculture.

At a fundamental level, passive house practitioners are engaged in a rebellion against poor quality design and construction. It’s becoming quite clear that this rebellion has legs and will endure. Given this, a question worth unpacking is whether the durability of the passive house movement is emerging as an architectural style. What are the defining principles behind architectural aesthetic decisions in the context of high performance homes and buildings?  What will the history books say about our little rebellion in the years to come? Join us in this rich and thoughtful discussion with two powerful voices at the top of their game in the passive house realm.

Tessa Bradley

Tessa is an optimist. She’s also tenacious and dedicated to creating designs that are stunning and sustainable at once. She uses her powers for good: in Tessa’s vision of the future, architecture is a cohesive part of creating the good life for more people — she believes that excellent design can help make a joyful life. 

With a tireless enthusiasm for problem-solving and a drive to tackle the toughest challenges head-on, she approaches every project with a blend of spunk, poise, and nerdy, sciencey know-how.

Big news! The Humid Climate Conference is coming back to ATX and it’s time for some appropriate FOMO. We’re just two weeks out. You will be so glad you made the decision to come to HCC in ATX. Both the technical knowledge and perspectives you’ll hear, as well as the realization and experience of the power, vitality and unstoppability of the growing community of folks in the AEC that are stepping up to move our industry and our society forward. 

The theme for HCC’24 is Transitions. The  work we do in the world as architects, developers, builders, trades, and even owners is important and it is also going through a series of transitions that together represent an altogether new way of delivering buildings to clients and communities. The Energy Transition, the refrigerant transition, the transition to lower carbon designs, both embodied and operational, are all “in play” right now. Now is the time to learn about them from visionary thought leaders and boots on the ground who are both showcasing these transitions and helping make them happen. 

Here’s the HCC website and here’s the link to buy tickets.

What if it’s true that “We can not solve our problems using the same level of thinking that created them”? - Attributed to Albert Einstein

Could it be that our building science understanding is limited? Could it be that even the clarity of understanding we gain by viewing homes and buildings as a systems of systems, assemblies, materials and products interacting according to the laws of science and nature - is necessary but not sufficient to cause us to build that way? 

Building science is a necessary understanding but it is proving insufficient to cause the change we want at the pace we need. What do we need to add to the building-as-a-system perspective? What will it take to get past Knowing How to get us to Actually Doing what it takes to design and build for the outcomes we need? Using that concept as a lens, this episode seeks to expand the building-as-a-systems view into the society-as-a-system view in order to find ways to allow the power of building science to have proper impact in society.  Anyone working in the AEC knows that the barriers to change are solid and weighty. This is what motivates our search for Leverage. 

Leverage is a force multiplier. Leverage creates a large powerful force using a smaller force. We need leverage to multiply the force we can exert to cause change to happen in the AEC. Following the insights from Donella Meadows(2), we focus on the concept of Leverage Points - those “places within a complex system where a small change in one area can have pervasive positive impacts”. What we will discover is that according to Donella our mental models of the world, our industry, and our role in it - our deeply held, often unexamined, paradigms, are points of power that bring leverage. 

Please join us for this rich and thoughtful exploration to find sufficiency. What will it actually take to bring the future we want into the present we have. Bring your caring hearts and curious minds and let’s have some fun!
