“Air does not have borders. Water does not have borders. Humans do not have borders...” - Dionne Brand. TFW when my heart and #buildingscience are 100% in sync.

@duncancampbell Any chance this can be updated to present? Looks like it only goes through 2022. By the way we've found this very helpful and thank you for the tool.

Me, on the absurdity of our approach to indoor air quality standards v. outdoor air quality (you will be shocked by what I share, and you will agree it's absurd.) Thanks to @EricTopol for having me on. Full links to our 60-minute interview in his bio.

@drvolts So sorry about this, David but also glad you're ok! I hope you feel better soon and plan an even better trip.

The end, I guess! I sure will be glad to get back home to my pups.

I had to run out of the customs line to go to a bathroom, where I spent several minutes sitting on a toilet, sweating, with nothing happening. I also puked several times, though nothing of substance, just green bile.

Sound Smarter on the Jobsite: "Send me the CAD files."
Haven't done one of these in a while!
As yesterday's lively discussion reminds us, many people really don't understand this issue, and get quite spicy about it.
Why is this such a touchy topic?!
Let's get into it:

Microplastics are so tiny they can get past the blood / brain barrier. They are just one kind of micro-particulate in indoor air. This article is a great way to visualize and understand some of the ways that indoor air pollutants interact. washingtonpost.com/climate-enviro…

@mwmoedinger Bravo to your whole team, and especially to your ability to set objectives at the start, use a building science approach, and verify your results.

Just posted 0.8 ACH blower door test results on a renovation of a 100+ year old house we're working on.
That's a pretty big deal!
We tested this one *before* putting up drywall, so we could address any air leakage/insulation issues before walls are closed up. We'll test again at the end of the project; it should be even tighter.
Results like these are a testament to a lot of teamwork: design, engineering, GC, and subs. And frankly, we didn't have to do a ton of weird or over the top details. It's mostly everyone paying close attention and doing their jobs well.
We also planned for the house to be this tight, and have a Zehnder whole house ERV system, properly sized kitchen exhaust, etc. When a house is tight, you have to "ventilate right" to avoid moisture issues or CO2, etc issues.
All this effort is not only good for general energy use reduction, but also for comfort, lower energy bills, and a better quality build over all. And the inside of the house is *so* quiet!
Proud of the team today 🥰🛠️

It can be done! Buildings are a system of systems. The best time to get it right is at initial construction. The second best time is at the point of significant remodel or renovation. You can even get it right during a general energy retrofit - building science is the key.

Hands-down, the best part about this heat pump hot water heater is that when it is hot and humid outside (like today), it air conditions and dehumidifies my garage workshop.

Smooooooth! And yes you can bet I'm learning this song and playing it around the campfire at my upcoming family reunion.

For 6 years people have told me to "Make Heat Pumps Sexy". I told them "Highly efficient, pollution free heating and cooling is sexy enough!" But they didn't stop. So here is your sexy heat pumps. #imyourheatpump switchison.org/news/im-your-h…

@KHayhoe Thank you so much for all of the awareness you are building - and also thanks to Amy Harder for the article about the ongoing energy transition. I can only hope these weather shocks make the need for a clean energy transition quicker and more obviously needed to naysayers.
English
@CanaryScience The changes we are seeing today are in response to everything we've done over the last few decades. Like a slow-moving ship, the wheel may be turning, but it takes a while to see the effect. The article above is about the wheel and our projected future path.
English
The amount of warming Earth is projected to face in coming decades has DROPPED since 2015.
“If we don’t talk about what has been accomplished, we are disempowering and discouraging people from taking action,” @KHayhoe says.

Like many, we were surprised to learn that, as early as the 19th century, public health specialists and engineers knew precisely how to create the ideal conditions for limiting airborne transmission and promoting learning. Here are some of the pioneers of indoor air quality. 🔽

While we're talking about numbers...great progress in lowering the outdoor air pollution limit for PM2.5 from 12 ug/m3 to 9 ug/m3. Do you know what the legally enforceable limit is for *indoor* particles? Have a listen.

Glad to share our recently published study in ES&T Air evaluating 13 different air cleaners for PM and VOC removal under wildfire smoke conditions. We evaluated 13 different commercial and DIY air cleaners in a test chamber w/ pine needle wildfire smoke challenge

@drvolts @corawentwhere @rewiringamerica Order of improvements matter. Address that post-retrofit conditions after building enclosure improvement must be verified via blower door / ASHRAE 622 to properly size new heat pumps, and also associated indoor air quality negative impacts of wrong order implementation.

On Wed. I am recording a podcast with @corawentwhere, research director at @rewiringamerica, about their new "personal electrification planner." This will be about the practical nuts & bolts of electrifying your home: where to start & what to prioritize.
Any questions?

what is this nuttery?
also:
how do I get involved?
will my family collude?
