HOMEChem Interview with Arlene Blum

Corbett Lunsford

Arlene Blum is a famous mountain climber AND biophysical chemist, and it turns out they're basically the same job. At the Green Science Policy Institute in Berkeley, CA, she sat down with Corbett and Grace to talk about Six Classes of harmful chemicals, how to recognize when you're being duped by lazy industrial processes and marketing magic, and what to do to protect your kids from fluorinated products, antimicrobials, flame retardants, bisphenols, phthalates, and certain solvents and metals.

Tour the Off Grid Homestead with Chris Laumer-Giddens

Corbett Lunsford

Last week I made my first site visit to the mountains of North Carolina to start performance testing the #OffGridHomestead. This is an uber-homebuild with LG Squared Architects (now also LG Cubed Builders) and Chris Laumer-Giddens has a lot to show us, even at this rough in stage, with saws running and tractors rumbling around.

2 Years Later: is #TinyLab Still the Highest Performance Tiny House on Wheels?

Corbett Lunsford

Grace and Corbett built the world's highest performance tiny house on wheels in 2016. It was perfect. Then they toured it 13,000 miles across America and let 7,000 people come inside to feel, hear, and smell what perfectly tuned home performance is like.

What's the house performing like now, after all that torture? And under 2 inches of snow in Atlanta, Georgia? See for yourself in this 20-minute tour, complete with testing, demonstrations, and metrics that show Proof Is Possible, even for people who have never built a house before. The #TinyLab is still the undisputed most scientifically superior home performance demonstration in the world, and we sincerely hope others start challenging our work!

Tour of the Building Performance Workshop in Atlanta

Corbett Lunsford

Welcome to the inaugural tour of the real life Building Performance Workshop on our high performance homestead in Atlanta, Georgia! From the translucent walls and roof to the airtight, insulated and dessicant dehumidified Dry Vault inside it, everything here is about making the invisible dynamics of building performance visible. Stay tuned for the blower door test, infrared thermal scan, air quality testing, and much more when the Workshop is built!

Home Performance Homestead Begun in Atlanta!

Corbett Lunsford

Now that Corbett and Grace's 26-state Proof Is Possible Tour is over and 7,000 Americans have been brought into the illuminati of home performance, they get to have a real life for awhile. Here's a weird moment from their weird life in Atlanta.

Do Tankless Water Heating Systems Perform Better?

Corbett Lunsford

Watch home performance diagnostics guru Corbett Lunsford test the performance of demand tankless water heaters, in the #TinyLab and in a big house.  You may be surprised to see that it doesn't work exactly as advertised.

Carbon Footprint. Sustainable. Life-cycle Analysis.  Zero impact. Eco-friendly. Green. Greenwashed. The terminology is as diverse as the people involved in what we’ve come to call “the environmental movement”. The origins of the movement are equally diverse. In his book, Blessed Unrest, Paul Hawken goes so far as to suggest the growth in environmentalism might be a biological reaction of the planet’s dominant inhabitants. Deep down, our instincts are telling us we must protect our habitat in order to survive.  It’s no longer “Save the Whales” now it’s “Save Us!”

Theories. Musings. This is fun stuff to think about, and is partially what this blog is: Exploring where this movement came from and where it might be going. Many people have widely varying opinions about this, but the fact is that the future is a clean slate. To take Donald Rumsfeld’s words out of context “as we know, there are known knowns; there are things we know we know. We also know there are known unknowns; that is to say we know there are some things we do not know. But there are also unknown unknowns — the ones we don’t know we don’t know.”

There are technologies that have been in development for decades and are widely written about like photovoltaics and electric cars. But for as often as these are written about, there are hundreds quirky solutions that very well may become leading technologies. For example, Richard Wool at the University of Delaware is exploring how to make circuit boards out of chicken feathers. Or how about the National Environmental Research Council, who are studying ways that oysters and mussels (because they naturally filter water) can be used to combat water pollution.

If you choose to participate in this blog (and we really hope you do) send us the weird, fun environmental “hey-I-heard-abouts” that make for interesting reading and writing.

Mostly, however, this blog is about people. There are hundreds, probably thousands, of people in this city who consider themselves environmentalist. Heck, there are probably dozens of environmentalists in Chicago who never call themselves “green”. They’re simply trying to do the efficient, respectful, and smart thing. From the gloom-and-doom professor to the vegan cyclist, from the local insulation man to the master composter, from those mining the alleys for treasure to those handling Chicago’s municipal waste; This blog is to explore the subject of “Green” from all angles.

In 1971, Greenpeace rented 12 billboards and posted this: “Ecology: Look it up! You’re involved”. Thank you for being involved, and thanks for participating in our new blog!

Looking Forward,
Steve
