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 âWhy stop there?â Why not identify a broad range of pollutants and contaminants in the airstream and also select and remove them as well?
Enter metal 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 simpleâthey 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 âgood oldâ 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!Important Links!

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 olâ thermodynamics isnât 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 (CPHCÂź) training and WUFIÂź 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 Masterâs 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 Mastersâ thesis posed the question âWhat do Net Zero Buildings Cost the Grid?â, 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 â 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 Phiusâ 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 âlifeâ is more narrowly defined by architecture as âcomfortâ or âcomfort, health and well-beingâ. At its core bioclimatic design asks âWhat are the climate opportunities?â. 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. Weâre happy that youâre noticing and valuing that we âgo thereâ 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. Itâs time to start.
If the term materials economy is somehow just a bit bland and doesnât connect or feel engaging for you, consider these two facts to remind you of what weâre 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, Ginaâs strategic partnerships and innovative practices have reshaped housing standards across the affordable housing sector. With a proven track record of creating healthier spacesâincluding the groundbreaking 90-unit apartment building, The RoseâGinaâs leadership drives Habitableâs mission forward. She sees herself as a âdot-connectorâ and translator who amplifies the organizationâs impact, fostering holistic solutions for planetary health. Determined, curious, and joyful, Gina is committed to creating healthier environments for communities worldwide.

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 âsimpleâ 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 weâre 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, thereâs 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.

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 âholy triumvirateâ 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 youâre 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 heâs 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. Itâs 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.

What if itâs true that âWe can not solve our problems using the same level of thinking that created themâ? - 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 âplaces within a complex system where a small change in one area can have pervasive positive impactsâ. 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 letâs have some fun!Reference: Donella Meadows, Thinking in Systems: A Primer

How do we design and build affordable net-zero, carbon-negative homes? That important goal is the subject of todayâs episode and is the focus of a multidisciplinary team that includes PNNL, Virginia Tech, and Green Canopy NODE. On the podcast today youâll hear from Patti Gunderson with PNNL who is working with a talented team who are taking a thoughtful approach to this ambitious goal. One that focuses on modular design, carbon sequestering materials, thermal/energy efficiency, and a forward-looking circular approach that relies on cleverly designed, factory-built, bio-based materials right from the start. The outcome is a home that supports an ownerâs right to repair (we need this with so many so-called durable products in our world today) and also allows the materials in the home to be disassembled and reused and the end of the home's lifecycle.
Patricia Gunderson
Patti Gunderson joined PNNL in 2021 and supports several projects in both the Energy Policy and Economics and Buildings and Connected Systems Divisions. A particular strength is collaborating with manufacturers, designers, builders, and trades people to understand and overcome barriers to adoption of optimized building technologies.
Patti most recently spent nearly six years at Home Innovation Research Labs where she proposed, designed, and led research projects to study constructability, functionality, energy efficiency and durability of buildings. Her background in building physics, engineering software tools, systems design, discipline coordination, project documentation, and construction administration provides valuable insight for research, analysis and client support.
Prior to HI, Patti worked in the DC office of SmithGroup, an international AE firm, on numerous high-profile projects including embassies, medical centers, university law schools and the flagship Net Zero Brock Environmental Center for the Chesapeake Bay Foundation. Patti is a big fan of collaboration and has benefitted from research partners and clients representing several national labs, the National Association of Home Builders, the Leading Builders of America, and numerous international manufacturers, as well as staff from DOE, FPL, HUD, and VA.

You donât have to be a building nerd or an engineer for a question like this to be relevant and important to consider. There are many reasons why AWHP systems make an attractive alternative to our batch of current ânormalâ heat pumps that rely on refrigerant for thermal distribution. Some of the reasons AWHP are appealing include: (1) reduced refrigerant volumes, thus reduced refrigerant leakage into the atmosphere; (2) larger selection of indoor unit options relative to refrigerant based systems; (3) the ability to support comfort via thermally active surfaces (aka radiant heating/cooling); (4) your home is better future-proofed and more technology-agnostic, and (5) these systems affordably unlock thermal storage (for thermal loads), which can provide energy resilience for their owners as well as dispatchable grid-level energy storage This episode is why you listen to the Building Science Podcast, somehow this multifaceted emerging story has still not hit the mainstream.

We spend the vast majority of our time inside yet we actually know very little about what it means to live indoors. This is the case even though what happens indoors impacts us in nearly every way. Our comfort, health and overall well-being all are deeply impacted by what's in the air we breathe and whatâs happening in and on the surfaces all around us.
Enter Corbett and Grace Lunsford. Knowing that what we donât know about our homes matters a lot, they took on the challenge of creating a TV show on home performance for mainstream audiences. Their show, now in itâs third season makes it clear that a âgood homeâ is far more than what it looks like and how much it will sell for in the market. In the process, Corbett and Grace have become leading voices in the role of educating us about the many and hidden dimensions of home performance. Join us in this episode as they unpack the why, the what, and they created the Home Diagnosis TV show on PBS.Corbett Lunsford
Corbett began working in the realm of home performance expertise in 2008 with Grace. He quickly discovered the challenges within the construction industryâits inherent messiness, time constraints on professionals, and inadequate compensation, all of which adversely affect homeowners throughout their lives. Their shared objective is clear: to present building performance in an accessible manner for both professionals and consumers, contributing to the improvement of structures globally.
In 2009, Corbett initiated the Building Performance Workshop. He has also been prolific in sharing knowledge through more than 500 YouTube videos, 80 interviews for the Building Performance Podcast, and the authorship of the book "Home Performance Diagnostics: the Guide to Advanced Testing." Additionally, he developed the APT Reports software tool.
Not bound by conventional expectations, Corbett and Grace designed and constructed the world's highest performance tiny house on wheels, the #TinyLab, in 2016. They toured the U.S. and settled in Atlanta, Georgia, creating the groundbreaking TV series "Home Diagnosis," the first of its kind on public television across the U.S.
Grace Lunsford
Grace Lunsford is the powerhouse behind The Building Performance Workshopâs videos and the Home Diagnosis TV series. She started the 'Home Performance' YouTube channel, and has produced over 500 videos to date, gaining 4 million views and 23k subscribers. Grace is the creator, co-host, and Executive Producer of 'Home Diagnosis', the first-ever TV series about measured home performance, which has aired on over 60% of the PBS stations across the U.S. Her short films and feature film, The Other One, have won awards at film festivals, and as a Hewlett-Packard sponsored artist, she presented workshops on her work methods at both Sundance and Cannes.
She founded the media firm Sterling Rock Productions because the media she wanted to see was not being made. She has served on the Boards of Directors of the Screen Actors Guild Midwest and the Illinois Production Alliance (which lobbies for tax incentives in the film industry), where she spearheaded an initiative to bring the production of major motion pictures and television shows to Chicago. She also founded the 501c3 Chicago Acting in Film Meetup, a professional support group of over 150 screen actors.
Grace's career in film and television and voiceover continues in Atlanta, GA, where she's represented by Stewart Talent.

Moving heat with a heat pump is an unsung superhero in the global energy transition. Chances are nearly 100% that youâre using a heat pump right now - to heat or cool yourself, refrigerate your food, or keep your car comfortable while you drive. The vapor compression process may be the thermodynamic engine of a heat pump, but where the rubber meets the road is the heat exchanger, aka âthe coilâ.
Getting heat exchanger coils right is a balancing act. On one hand we want the coils wall material to be as thin as possible so they move heat efficiently, on the other hand we donât want the working fluid, typically a high GWP refrigerant, to leak out into the sky. This is a costly hassle for us as well as a tragic outcome for the atmosphere.
This is the backdrop for todayâs conversation with Todd DeMonte on coils, coil failures, and the future of refrigerant based heat ex. Todd has been one of many smart folks around the world working to help society move past the vexing issue of formicary corrosion. Enjoy the feast of ideas in this episode! -
As a society we are learning, slowly but surely, how to design and build healthy indoor spaces for ourselves and our loved ones. Seeing the need to both guide and accelerate this learning process, Paula Baker LaPorte and her wingman John Banta and Erica Elliot MD dedicated themselves to write a book. This happened 35 years ago with the 1st Edition of Prescriptions for a Healthy Homes, last year (in 2022) the 4th Edition was published and it is a richly updated treasure trove of motivation, guidance and actionable information that we all need to know more about. What we need now is a step change of sorts in the way society thinks about and delivers housing to itself. We need a Healthy Home Revolution.
With that in mind, Kristof sat down with Paula to have a conversation about her journey exploring and understanding the connection between the built environment and our health. After hearing her stories and absorbing the understanding and knowledge in her book, it is clear that homes can be so much more than we currently ask them to be. Homes are more than a visual-spatial-economic situation, more than a place to hold ourselves, our families and our stuff, more than an exercise in energy efficiency and resource use; The places we live are in truth highly immersive and tactile experiences for our bodies and minds, and profoundly impactful opportunities to promote our health and the health of the planet.
