I think about buildings and the built environment a lot. Optimist. He/Him. Views are mine.

Is it Murray from the Wiggles?

Genuinely curious, did you do any edits to the blog posts at all (except for P.S.)? Im trying to figure out whether you modified the assessment of research assistants.

This is not a fast supply chain either.

Going to have change my routine on the train ride home. Just got done learning about MacIntyre and curious how he'd answer these questions.

Also I didn't realize he was still alive up until last year. Dood had a good run.

To answer your second question, I dont think you learned anything from Colonialism.

Super fun read. Now I want to figure out the Cambrian explosion.

Im also thinking about what the max resolution is for any given distance at any given time. Thanks for ruining rest of my workday, Phil!

Yup, I totally agree with this. I'd add when it has to be used, servicr life should be a critical element of design.

Sorry. To clarify, how much concrete is going into building sector and how much into the transportation sector? its one thing to replace a concrete building with 0GHG buildings, but another thing to do the same for bridge, overpass, piers, etc.

This will definitely help. Id like to see the concrete industry take ownership of its footprint and step on the gas (NPI). Im submitting a proposal to speak at World of Concrete 27 about sustainability.

Block is pretty great for high wind areas. But yes, its not really needed in moderate climate areas. BTW you shouldn't look at what Im buildin.

Seriously asking because I don't know, but do you have a an idea of the breakdown of concrete used in construction vs transportation? Theres less good alternatives in transportation space.

I'm OK with high carbon materials as long as its service life is long enough.

It kills me when I see <50year old commercial building demolished though. Those are the practices we need to stop.

Thinking about pitching a new pilot to CBS, The Fat Man and the Potato. Think it will work?

Having a durable grid is important to renewable adoption. I dont mind my utility charging me for grid reliability... I do mind when they are using those funds to invest in production. Regulation need to catch up and incentivize both sides of the equation.

An important and underappreciated fact of electricity economics: The US average *wholesale* electricity price is ~5 c/kWh, or ~25% of the average *retail* price of ~19 c/kWh. The other ~75% of the electricity prices we pay is about poles, wires, transformers, generation capacity, and utility profit.

โ€œBills, Commanders, obviously the Steelers, I think the Giants for a bit there. Huge reservoir of talented offensive and defensive minds. Jimmie Laycock has a coaching tree to rival Yggdrasil. โ€

I asked about interior and exterior vapor sealing and it gave me the the article. Better than most Ai. I got spray foam on the outside with this as my finished interior wall. Should be OK since we sealed the rim joists and top plates if next floor

This is legit. Link on BSC website has it. I'm amazed Joe got into the modern era. He and Betsy are they absolute best people.

I created a building science feed to try and pull this stuff out. Tbh, theres not much in the way of construction activity on BS. Your content is pretty great.
