That's How The Light Gets In by Positive Energy

Architecture that interacts skillfully w/ the sun is needed now more than ever. Beyond just light and heat there are broader implications and deeper relationships between the building skin and aperture that are not always transparent during the design process. It's time to develop a sympathetic understanding of interrelated decision factors. Enter Matt and Dason and their new book that seeks to fill a void in the understanding and practice of  designing around the Sun. This is an architects resource for moving the industry forward with the design of apertures - both the pragmatics and the poetics. This interview shares a feast of ideas related to this evolving field with two of its thought leaders.

Architectural Science and the Sun: The poetics and pragmatics of solar design

"Architectural Science and the Sun begins with the premise that great architecture goes beyond energy performance and the visual-aesthetic to engage all of the senses. Given that the stimuli to which our senses respond are physical phenomena such as light, heat, and sound, the designer must manipulate these parameters through the craft of building form and technology. Successful sustainable design is a balance between the creation of physical artifacts and a comfortable sensorial experience."

Just Don't Tell Them It's Passive House! by Positive Energy

If you’re ever wondered what kind of salt it takes to move the needle for multi-family passive house projects, look no further than the story of architect and developer Hank Keating. We all have under utilized power in our professional roles. Join Kristof for a discussion with Hank about the work he’s done in Massachusetts to make way for passive house buildings - from codes, to renter occupants, to design - this episode’s got it all.

Hank Keating, AIA


Mr Keating is a registered architect with more than 30 years of experience in the design and construction of multifamily affordable housing projects. Recently retired from Trinity Financial, (but consulting back on select projects) Mr Keating completed over nine affordable housing developments totaling over 1500 units in Massachusetts, Rhode Island, Connecticut and New York City while at Trinity. For the last 10 years Mr Keating has been engaged with the Passive House movement and designed and completed a passive house for himself while pushing to move Trinity’s large scale affordable projects toward the Passive House Standards. He managed the Bristol Commons / Lenox Green project in Taunton which created 160 affordable units built to near the passive house standard– 4 years of data tracking demonstrates that the project is using 80% less heating energy that comparable LEED GOLD projects in Massachusetts. Since retiring, he has been consulting with Trinity during the design of 425 Grand Concourse, a 26 story, 270 unit, affordable passive house project in NYC.  Mr Keating is currently on the Passive House Massachusetts Board of Directors and has been leading the efforts of its Public Policy Committee to get passive house incentives included in the upcoming EEAC Three-Year Plan for utility company incentive programs. In addition, he is on the MassCEC Passive House Challenge Selection Committee and has been working with DHCD to encourage the addition of QAP bonus points for passive house projects.

Green Builder Article On Hank

“This unique home’s smart and solar bells and whistles reduce its ecological footprint even more.

Building a home up to standards required to be deemed “passive” might make some builders cringe. But when the Valle Group received such a request, it was almost par for the course. The Cape Cod, Mass.-based builder specializes in carefully planned, energy-efficient homes.”

Passive House Massachusetts

Passive House Massachusetts is a member-based non-profit organization that promotes a healthy and comfortable built environment that significantly reduces energy consumption and lowers carbon emissions by utilizing the Passive House building standard and other high-performance building strategies, focusing on education, training, outreach, and advocacy.

PHMA members include designers, builders, engineers, policy makers, students, community leaders, and all those interested in high-performance, energy efficient buildings. From regular member meetings and educational programming to tours and special events, there are plenty of way for members to become involved and membership support is essential to our work promoting and expanding the use of Passive House and high-performance building. 

End Game Refrigerants by Positive Energy

Refrigerants are all around us and we barely ever notice. They are a hidden force in creating the comforts we have grown to think of as normal and yet many of us know little about them. Rethinking refrigerants is considered by many experts to be the #1 way to to combat and draw down climate change given how much carbon they can add to the atmosphere when not created and handled correctly. This episode features John Miles of Sanden Water Heaters in a ranging discussion of the effects and behaviors of refrigerants that might just blow your mind a little.


John Miles

John is the general Manager of Sanden Eco Products and is responsible for bringing Sanden's range of CO2 powered Heat Pump Water Heaters into the North and South American marketplace and creating a revolution in the HPWH industry.
He works to establish a sales network of Independent Sales Reps and quality wholesale distribution plus adding people to Sanden’s in house support network and is in charge of overseeing Sanden’s marketing campaign, which is beginning with adverts in the HVAC/Plumbing trade press, as well as podcasts like this one.

Big thanks to Sanden for supporting the show and for talking with us at AHR and to The Humid Climate Conference for their continued and generous support of our show. 


You Don't Know What You Don't Know, You Know? by Positive Energy

The state of our current housing industry’s understanding and treatment of HVAC systems is in quiet crisis. Systems are routinely installed incorrectly to the detriment of the environment both on a macro scale and on the micro scale of the air quality inside people’s homes. In this episode, Kristof interviews Sean and Ian Harris, the owners of IAQ Texas. You'll hear discussion on why quality duct installation is crucial for good indoor air quality outcomes. 

Also, we talk about Aerobarrier. It’s a little sneak peak for our full episode with the CEO of AeroBarrier, Amit Gupta, to be released soon!

Texas Goes Passive by Positive Energy

Is Dallas, Texas ready for the state’s first internationally certified Passive House? Kyle and Connor Fagin think so and they’re betting on it. Join Kristof as the Fagin Partners tell us their unique story of operating in the developer driven construction world to sacrificing profit for the principled push forward in industry transformation.

Kyle Fagin


The first home Kyle ever built was a tree house for his three awesome kids. Sometime after that he began a major remodel on a mid-century home for his family and was heavily involved in all aspects of the project. A year or so later he was part of a team that designed and built the family lake house in East Texas. He discovered building really suited him and it seemed that he had a knack for it as well. He built commercially for a while, but found residential much more enjoyable. His true passion is learning how to build the most efficient and sustainable homes that can be built and now does this alongside his son and partner Connor. When he's not working, Kyle enjoys biking, sailing, being outdoors and spending time with his wife, Christy, and his three kids.

Connor Fagin

Connor is a graduate from Baylor University. He has always been deeply involved in community adventures; he helped to develop the Dallas High School Meals on Wheels advisory board, which is still active today. He is a self-proclaimed techie and stays on the leading edge of any technology that can enhance his own life as well as the customers. “I truly enjoy the fact that the changes I help people make to their little slice of the American Dream is something that they will enjoy and be proud of for years to come.”

Fagin Partners

Kyle and Connor are extremely proud of the homes they have built and are building; their focus is on their customers, the environment, and the union of the two.

The homes built by Fagin Partners are efficient, sustainable, consistent and include the forethought to make it the most comfortable home for their customer. The attention to detail in each home allows each customer to be sure their home is uniquely theirs.

Fagin Partners sees the value in doing good for the environment but also appreciate that these efficiencies greatly impacts the customers. Through innovative materials and technology we create our unique yet comfortable homes. We are constructing homes today to prepare for the changes and needs of the future.

At Fagin Partners, we sacrifice profit on each project to create a high preforming product that pays our customers back every month, year after year.

A Look Inside Texas’ First Internationally Certified Passive House

Sense Energy Monitoring System

Every electrical device has a unique electronic signature — its own voice. The Sense home energy monitor listens to those voices through current sensors in your electric panel. It records them millions of times per second. Then advanced machine learning detection algorithms work to distinguish one appliance from another — to recognize each individual voice. Over time, more and more devices are discovered as the Sense community grows.

Flo Smart Water Meter Monitoring System

Flo by Moen is installed on the main water supply line to the home. Because it’s installed in-line, this allows Flo by Moen to monitor all water going into the home. The device has three sensors that actively monitor water flow, pressure, and temperature. These sensors, in combination with Flo by Moen’s algorithms, are what enable Flo by Moen to detect and protect the home from problems like leaks, burst pipes, etc.

There's What In This Building?! by Positive Energy

Welcome back for our Season 5 premiere! We decided to kick the year off with a timely and important topic - chemical exposures via building materials. Modern building materials are generally feats of engineering marvel - we’ve managed to manufacture countless high performing systems, yet it has often been at the cost of human exposure to harmful chemicals. But it’s not a hopeless situation. There are people who are helping the average consumer understand what’s what. Join Kristof in a wide ranging conversation with Gina Ciganik and William Weber from the Healthy Building Network.

Breathe Like You Mean It by Positive Energy

Live from The HIVE Conference held in Austin, TX in 2018, we’re proud to bring you one of the brightest minds in the discipline of indoor air quality research, Dr. Brett Singer from Lawrence Berkley National Labs. Join Kristof as he discusses a broad array of topics that affect every single person who breathes inside a house (so, ya know, most people). It’s our last episode of 2018 and season 4 so we made sure it’s extra long (almost an hour and a half!). Enjoy it and we’ll see you next year!

Dr. Brett Singer, PhD

Brett Singer Positive Energy

Brett C. Singer is a Staff Scientist and Principal Investigator (PI) in the Energy Technologies Area of Lawrence Berkeley National Laboratory. Dr. Singer is the Leader of the Indoor Environment Group and co-leader of Indoor Air Quality research in the Residential Building Systems Group. 

Dr. Singer has conceived, conducted and led research projects related to air pollutant emissions, physical-chemical processes, and pollutant exposures in both outdoor and indoor environments. His research aims to understand the real world processes and systems that affect air pollutant exposures. His guiding professional motivation is to provide the scientific basis to inform energy and environmental policy.

Dr. Singer leads the Indoor Environmental Quality project within the US-China Clean Energy Research Center Building Energy Efficiency Program.

A major focus of Dr. Singer’s work over the past decade has been the study of environmental quality and risk reduction in high performance homes. The goal of this research is to accelerate the adoption of IAQ, comfort, durability and sustainability measures into new homes and retrofits of existing homes. This is achieved through the mechanisms of buildings codes and standards; training of builders and contractors; public education; and technology development – all supported by robust research. The IE and RBS research groups conduct in-home studies, controlled laboratory experiments, simulation-based studies and data analysis to identify the most effective and energy efficient air quality control strategies.

Dr. Singer’s early career research examined on-road motor vehicle emissions and the effectiveness of California’s Smog Check program. His first project at LBNL examined the sorption of secondhand smoke compounds, an effect that contaminates materials and leads to extended odors and pollutant exposures. This work helped launch interest in the study of “thirdhand” smoke. 

Dr. Singer has authored or co-authored over 50 papers in archival, peer-reviewed journals and dozens of technical reports and peer-reviewed conference papers.

Do You Have 2030 Commitment Issues? by Positive Energy

To support the 2030 Challenge, the American Institute of Architects created the 2030 Commitment Program, aimed at transforming the practice of architecture to respond to the climate crisis in a way that is holistic, firm-wide, project-based, and data-driven. Over 400 A/E/P firms have adopted the 2030 Commitment, and firms from all over the country have been tracking and reporting projects since 2010, with over 2.7 billion ft2 of project work reported in 2016 alone. Join Kristof as he interviews Nathan Kipnis of Kipnis Architecture + Planning as they discuss the 2030 Commitment and all topics in-between.

            A KAP design was selected for this international design competition and built.

"He is one of Chicago's new breed of up-and-coming architects, who blends excellence in architecture with a social conscience. Before the advent of air conditioning, before electricity, everything that was built related to nature. Nate understands that. He made a habit of it long before it was fashionable.” — Stanley Tigerman, FAIA and co-founder of Archeworks.

Viewing the mission beyond his own practice of architecture, Mr. Kipnis’s leadership was instrumental in helping to develop the idea of an offshore wind farm in Lake Michigan off Evanston's shoreline. The work led to a Design Evanston Urban Design/Planning award, and the project is now on the DOE's list of potential offshore wind farm sites. 

Additionally, he currently serves as Co-chair for The National AIA AIA 2030 Commitment’s working groups. In this capacity, he assists architects with the AIA 2030 Commitment, whose goal is to design full Net Zero buildings by 2030. 

Nathan Kipnis also lectures extensively on topics related to sustainable architectural design and renewable energy. He has been an invited speaker at numerous symposiums and conferences, including at national AIA conventions, the Chicago AIA, Archeworks, GreenBuild, The Midwest Renewable Energy Association, the Center for Green Technology in Chicago, and Northwestern University's “Green City Summer Institute,” as well as being one of the keynote speakers at the Mother Earth News Fair, among others.

Recognized as Chicago’s premier award winning sustainable architectural practice, Kipnis Architecture + Planning (KAP)  was founded in 1993 and is based in Evanston, Illinois.  KAP has practiced the architectural design philosophy of 'High Design/Low Carbon™' long before it was in vogue.   They are guided by the idea that architectural design excellence need not be sacrificed for principles of sustainability. Rather, they believe sustainable design expands the possibilities for innovative architectural forms, construction methods and the use of materials. A particular expertise is the architectural integration of passive solar and bioclimatic design. They are early signatories to the AIA's 2030 Commitment, rigorously working towards having their projects be 'net zero' for their energy use by 2030.

Architecture 2030 Challenge

The urban built environment is responsible for 75% of annual global GHG emissions: buildings alone account for 39%. Eliminating these emissions is the key to addressing climate change and meeting Paris Climate Agreement targets. To accomplish this, Architecture 2030 issued The 2030 Challenge in 2006 asking the global architecture and building community to adopt the following targets:

  • All new buildings, developments and major renovations shall be designed to meet a fossil fuel, GHG-emitting, energy consumption performance standard of 70% below the regional (or country) average/median for that building type.

  • At a minimum, an equal amount of existing building area shall be renovated annually to meet a fossil fuel, GHG-emitting, energy consumption performance standard of 70% of the regional (or country) average/median for that building type.

  • The fossil fuel reduction standard for all new buildings and major renovations shall be increased to:

    • 80% in 2020

    • 90% in 2025

    • Carbon-neutral in 2030 (using no fossil fuel GHG emitting energy to operate).

These targets may be met by implementing innovative sustainable design strategies, generating on-site renewable energy, and/or purchasing (20% maximum) off-site renewable energy.

2030 Commitment Program

Join the 2030 Commitment today and become part of a growing network of designers striving to meet the 2030 Challenge targets. Commitment signatories gain access to a host of online tools, educational resources, and mentorship opportunities to support success.

The mission of the AIA 2030 Commitment is to support the 2030 Challenge and transform the practice of architecture in a way that is holistic, firm-wide, project based, and data-driven. By prioritizing energy performance, participating firms can more easily work toward carbon neutral buildings, developments and major renovations by 2030.

What Do Spec Homes Dream Of? by Positive Energy

If your house could go down a highway at 70MPH, would you trust your architect and builder to make sure it’s not going to fall apart?

Let’s face it - most people can’t build custom homes just like most people can’t afford a Lamborghini. It’s just not a financial reality for so many of us. But that doesn’t mean that we don’t want a car that doesn’t work well and it doesn’t mean we don’t want a high quality home to live in. It sure as hell doesn’t mean we don’t want a healthy environment for ourselves and our families. So what are the economic drivers of a healthy, high quality, affordable home? Join Kristof as he interviews Ben Broughton about the trends in construction economics, job site processes, market dynamics, and the ins-and-outs of quality.

The Omnivore’s Dilemma

What should we have for dinner? The question has confronted us since man discovered fire, but according to Michael Pollan, the bestselling author of The Botany of Desire, how we answer it today, at the dawn of the twenty-first century, may well determine our very survival as a species. Should we eat a fast-food hamburger? Something organic? Or perhaps something we hunt, gather, or grow ourselves? The omnivore’s dilemma has returned with a vengeance, as the cornucopia of the modern American supermarket and fast-food outlet confronts us with a bewildering and treacherous food landscape.
