My main concern is frozen pipes, other cold related damage to my home. Gets quite cold up here in Minneapolis. Lovely design ideas for a cabin though where the infrastructure is inherently more limited.

Cant you keep the space above freezing? Just not as warm as people would prefer

I've been thinking about the inverse problem. I live in a very warm city. Air conditioning (cooling spaces) is the norm, but tons of money are spent with installations, maintenance and the monthly electricity bill. The new houses are designed with zero consideration about ventilation, designers seem to take for granted that you are going to buy an AC system. Oftentimes, a very simple change in the project would be enough to improve ventilation, but apparently they just don't think about it.

Some months ago I moved into an apartment with good ventilation and started to do some simple experiments directing the air flow and staying in places where it's more concentrated and the wind is slightly faster, improving the heat remotion. I use, at most, a fan, and didn't feel the need for an air conditioner so far.

I wonder how much energy we could be saving. I'd love to find an article as thorough as this one but about air cooling.

Ventilation doesn't help much with humidity, which frequently overlaps with the heat.

I get by without AC in the northern Midwest, but I'd be inclined to get a window unit if there was more than a few uncomfortable nights a year.

We take the general concept of heating people, not the space, to heart for our outdoor swimming pool. While most other folks heat their pool, we go ahead and swim in the cold water... but we buy everyone in the family a wetsuit. A few hundred dollars on wetsuits each year is far better than many hundreds on propane every month.

As a swimming experience, you're getting what you pay for.

Just curious, what part of the world do you live in?

I've lived in cities where we experience anything between below zero to 120F throughout the year. I couldn't imagine not having AC/Heating in those areas even with more efficient ventilation/insulation.

Uhm.. for me it helps, and A LOT. Surely there are more factors involved, which I'm not aware of. I'm talking from Fortaleza, Brazil. Maybe the sea is bringing cooler air. I really don't know, I only have these pieces of empirical knowledge and my experience is very narrow, basically limited to this city.

Is that enjoyable?

How, that's a huge temperature gradient.

I live in Fortaleza, Brazil. Temperatures here are very stable along the whole year (78F - 90F, it rarely falls out of this interval).

I'm not advocating this no-AC model as a general solution though. I'm aware we're a bit lucky here. I used to live in Sao Paulo and temperatures vary more wildly there, sometimes within a single day.

Ventilation and air conditioning are two very different things. Unless it’s a central unit, the AC will be reusing the same air. In order to not die of lack of oxygen you need ventilation as well.
