02 Module 1 Lstiburek

This presentation by Joseph Lstiburek provides a thorough overview of how air, heat, and moisture behave in building envelopes, and how to design and construct these envelopes to prevent problems caused by these factors, such as condensation and mold growth.

Great talk which you can find in roughly similar versions in other videos on KZbin. In fact, I now feel bad because I commented on another video where Dr. Lstiburek gives this talk (at Berkeley) that I thought his attitude was quintessential engineer, caring only about the construction of the building, and not the aesthetics. I find in this, earlier, talk, his view is much more reasonable and measured. As he says here, if you want a building to last a long time, make it beautiful. His insights about LEED certification -- which of course carry a fair amount of weight with laymen like myself -- are very interesting (he views the whole thing as what I believe these days is called "greenwashing", i.e., pretending to be "green" and efficient but failing at the real task) and deserve a well-focused 5-10 minute video of their own. And now to go find that other video and delete my comment... 🤓

brutal no one ever has the courage to say what is wrong .joe thank you so much for sharing your knowledge, i learned a lot .a big hug from your fan number 2 😀 a lot of health and all the best

Great presentation. I love Joe's sense of humor.

[@th3giv3r]

Especially the part where he makes himself seem smarter by assuming everybody in his audience is stupid. True bravery on display here.

[@HWY66]

all architecture schools should be teaching efficient building performance as part of good design! and Joe's lectures are a great start....

[@TedKidd]

"If you do the wrong thing right, its still wrong, right?" Quality control of bad design insures you get bad design right.

[@JimBellamy]

So, Joe, how do you really feel about it? ;-> The KZbin title for this talk tells no-one anything about the topic of the talk: the serious need for architects and building engineers to learn and apply building science. Great examples of great mistakes. Always good to hear your reminders about the need for common sense in design. It's a serious story delivered in a humorous way. Thanks!

Excellent! Interesting and very educational.

[@dekonfrost7]

Dude yiu are the funniest guy ive heard in years. You would be a hit in my circle if friends. Its like when we were in the first grade trying to get milk come out of my nose.

[@TonyWadkins]

My hero of Building Performance

[@flukedogwalker3016]

He's the rockstar of building scientists, I wish he would do a good lecture on building underground homes. Which direction does the moisture in the soil go?

[@joshuasmith1215]

"...so don't do stupid things." LOL

[@VertigoGTI]

Lstiburek should open for Kevin Hart.

[@barkeater7867]

love it when he gets wound up.

[@ipeksahin4442]

Good joject .I met with him in Manhattan NY ,but i lost his business card

[@danielam1992]

Can someone advise which Willis Carrier book he is referring to?

[@dogfan4lyfe]

Tough crowd.

[@2awesome292]

People take care of really really really old and really really really really big buildings no matter what the cost lol

[@TedKidd]

Slams LEED min 9 Engineers enable this bs, "we don't measure energy, we simulate it" min 10

[@ipeksahin4442]

Hi Joe .I know hm from 53 street on Manhattan Hello Joe

[@joshuasmith1215]

I always get confused. So on a residential, is something like Tyvek home wrap what you would put on the exterior sheathing, because it's an air barrier and vapor retarder?

[@ASIRIDesigns]

Tyvek Homewrap isn't an air barrier or vapor retarder, in fact homewrap is highly permeable by design at 56 perms. If you choose this weather barrier, you would need to tape all the joints in the sheathing behind the homewrap to provide the first air seal. Then install your rigid insulation layer over the homewrap, and then a rainscreen over the rigid insulation. Ideally you would want something self-adhered if you want something air tight, like delta vent sa or siga majvest sa.

[@malarbusto]

The don't do stupid things mantra also extends to presentations! Duh!

Somebody needs to waterproof this guy's ego because he desperately needs validation of his personality.
