The focus of buildings should be: 1. Keeping dry and bulk water out/away. 2. Being as air tight as possible.† 3. Controlling vapour. 4.

It is comforting to see this discussion continues the great HN tradition of having a lively and wide-ranging debate about a complex scientific article or paper without ever bothering to read the article and paper. This is a rather complex paper, so I perused it for about five minutes. As such I consider my self a one eyed man among a hoard of shouting extremely opinionated blind people, so you should all listen to me…

Is it possible that all of your neighbors in your building have their heater on? This is what happened to me in a building in NYC. It would actually get so warm in the winter I would have to crack the window open or I would get a nose bleed.
As someone who also lives in Toronto: most things being built now are giant class towers. Now, glass sucks at insulation (even triple glaze), but—depending on the coatings—it lets in a lot of sun light and with that potentially heat. While in a perfect world there would be no / minimal exchange between the inside of the structure and the outside,† being too warm may be better than being too cold, as I'm guessing that…

The problem with buildings with windows that don't open, is that the windows don't open. What do you do if you want to open the window?
Get casement windows, which open on hinges, and that tend to have levers to apply force against a seal/gasket.

Same in France, I'm buying a condo and looking into all this for the renovation, and everybody is screaming "insulation by the outside".
If you want to make sure things are built properly, look into the topic of "building science": * https://www.buildingscience.com/documents/insights/bsi-001-t... Matt Risinger, a general contractor in Austin, Texas, has a lot of good videos on the topics: * https://www.youtube.com/c/MattRisinger/videos Even if you can't use the same techniques that he does (and pay for some of the premium products), it may be possible…
Then we can talk r-values, zoning rules, permitting and planning.
Don’t get me wrong, I’m a technophile, I watch American construction shows, and I bought a bunch of books on renovation at the same time as the condo, but it’s only a small part of what has to be done.

I was going to read the paper tonight. I do appreciate your summary.
One thing I've been doing lately is to highlight the fact that nothing in life is reduced to a single variable problem. No, a cow is not a uniform sphere of milk one meter in diameter.
I've been doing this because of just how many discussions seem to take one variable and assign to that one variable the entire end result of whatever it might be that is being discussed. Frankly, it's maddening. I couldn't even name something that, in the real world, is an honest single-variable problem (I'm sure someone will find something now and point it out; OK, now go find ten!).

The biggest issue I see is that LEEDs allow for a building that looks like a big heat exchanger, and has zero heat insulation to certify for high power efficiency in a cold climate. Canada, and Toronto area had tons of LEEDs certed luxury condos being heated like no tomorrow in Winter. Things are even worse in Vancouver, but that's offset by milder weather. The opposite picture is there in hot climates. Building with…
That's called Green Washing. Now, Snow Washing is the process in which dirty money is brought into Canada to purchase said assets.

>or I would get a nose bleed. Are nose bleeds associated with high temperatures?
As you heat some air the relative humidity drops. If your room is not leaky, the relatively humidity will rise as it cools back off, but if you're constantly leaking air your indoor humidity will approach that of the outside air raised to the indoor temp.
This is why energy recovery ventilators exist-- to exchange outside air without losing or gaining as much relative humidity change.
