5 Principles Of A Healthy Home by Positive Energy

Health is the new green - this message is seemingly everywhere these days. It's clear that a shift is underway in the way we think about our homes and buildings. A quality building does more than just use energy efficiently, it needs to provide for the occupants. This means recognizing that our clients will spend their time immersed in the air we create for them and that indoor air is a dominant exposure. Now is the time to get clear on how our homes and buildings relate to health, comfort and well-being and, more importantly, what to do about it.

Let's Get Legal-ish by Positive Energy

When we think about building science, we're thinking about systems and the unseen forces that contribute to the success or failure of a building. Some of the largest and most complicated systems and unseen forces in the AEC industry are the contracts that make or break a project. Join Kristof as he interviews construction attorney, Joe Basham, on all things funky and legal in the AEC industry.

Architectural Yogurt by Positive Energy

Put on your microbiology hats, folks. This episode of The Building Science podcast will dive into the great unseen world of microorganisms all around us inside our buildings down to the level of the ecosystems that grow on our HVAC coils. We're truly at a time when the health sciences and the building sciences are becoming more closely related than ever before and the future is a weird, wonderful world of intersectional and interdisciplinary scientific inquiry. Join us as Kristof interviews, Graeme Marsh about the weirdness of biofilms that you can't even see right before your very eyes.

Our Homes, Our Health by Positive Energy

It's normal these days to pay attention to what we eat. But what about the steady diet of air we breathe and soak ourselves in?  The impact of homes on health somehow manages to stay below the radar. Even our language is a bit evasive. Why do we say "sick building syndrome"? The buildings aren't sick, the people are. 

This episode is a step toward helping this important topic get some long-overdue and much-needed attention. Join us for an interview with Bill Hayward and Carl Grimes that took place at the 2018 IAQA Conference in Chicago, IL. as we discuss the Hayward Healthy Home Score. We hope you enjoy, take the quiz yourself, and share with your friends and families.

Forget What You Know About Buildings: An Interview With Kiel Moe by Positive Energy

In this episode, Kristof interviews Kiel Moe of Harvard's GSD about the energy flows and multiple re-thinkings necessary to change the future of construction and design. You may remember reading about Kiel's inspiration to us at Positive Energy in our blog post about the thermally active surface system we installed in our office, compliments of the fine and wonderful people at Messana and SpacePak. This episode is definitely headier than most of ours, so buckle in and be ready to hit pause, rewind, and take notes if you need. We couldn't be more thrilled that he stopped by the office to chat.

Design & Construction In Humid Climates by Positive Energy

Yes. We're going to have a chat about humidity. If you live in a heating dominated, dry climate you might be thinking "what good is this for me to hear?" and I wouldn't blame you. But frankly, the more we know about humidity, the better we can understand how things work without it too. So dig in and think about how moisture affects the things we design and build. In this episode of The Building Science Podcast, we’ll explore the potential upside and downside of designing and building in humid climates.

Don't Wait For The Market by Positive Energy

In our first episode of season 4, Kristof interviews James Geppner of Erase40 and Big Yellow Cab on the topic of behavioral change and market transformation. Building Science stands poised to change the way we deliver conditioned space to society. There are many angles by which we can dissect exactly how to do that. In this episode, we're going to explore how YOU can change the market.


James Geppner

James has advised and developed initiatives for nonprofits, new ventures and mature companies in infrastructure, technology, media, education, health and housing. Following his years in Project Finance, where he evaluated companies and studied markets, he has applied social science (and competitive theory) to a range of issues in order to see what’s shaping a market, a cause or a behavior.

He founded Big Yellow Cab in order to apply social science research and the procedures of behavior change to important social and environmental issues. He has advised nonprofits, new ventures and global companies. Most recently he did an extensive analysis of the market for passive buildings and the decision-making process of buyers, funders and end users in order to find clues as to how to increase the size of the market and how to reduce the barriers to widespread adoption of passive technology. He founded Erase40 in order to develop market based initiatives that drive up demand for passive buildings and in order to serve as a decision lab for different players in the building ecosystem. He is a graduate of NYU and of SGIB’s investment banking program.
