Then you shouldn't have an issue since you are basically living outdoors most of the time.

As long as there is enough air movement, it should dry things out.

The problem is condensation inside the walls. To deal with that, your wall has to be vapor-open to either the inside or outside, so it can dry. Standard interior paint is usually breathable.

Also, if you are leaving your windows open that much in winter you probably consume a lot of heating fuel and therefore generate a lot of heat, which also dries things out. That's how it worked with old wood houses - you generated a ton of heat to dry them out.

Thanks for that info! We don’t have any air conditioning, I live in a place where it ranges from 50-85 F throughout the year, rarely below 60 though. I’m trying not to install HVAC or heat until we have solar and storage installed that can support it, and it’s important to me that the house lasts and doesn’t contribute to ecological disasters such as climate change, micro plastic pollution, etc. I’m still learning a lot as most of my expertise is in software and not construction. I need to eventually strip off years of bad paint jobs with crappy paint, and I intend to use something breathable that lasts inside and out at that time.

Combined with what you said about it being wet, I'm guessing you live in the subtropics.

Building in a climate/ecology conscious way in tropical/subtropical places is very different than in colder places, and most of the knowledge out there is for colder-than-tropical climates, and frankly I don't know much about it.

But one thing that translates well between the climates is shade - shade structures and roof overhangs - especially on the sides that take the most solar load.
