> Older homes were designed to breath.[1] Was it purposefully desgined to do this, or did it just happen because of construction methods of the time?

Somewhat both. Balloon framing existed for houses when homes were heated with fireplaces and sealing the house could have been potentially dangerous as a result.

  Why would sealing a balloon framed house be dangerous? I know that you need blocking to help stop a fire from spreading between floors.

    If you heat with open fireplaces, then you can't seal the house unless you have really really good artificial ventilation (which you don't because it's 1840 still when you're building this house), regardless of how the house is built. A sealed house with a fire burning in it is a suicide machine.

        That's not an open fireplace, though? (And so while the house is sealed, the fire is not burning with the sealed boundary of the house.)

  I find the idea that balloon (rather than platform) framing was part of the heating design of a house a little hard to take. The moment we could switch to platform framing, almost everybody did (not least because shorter studs were cheaper). But a balloon framed house with a fire that escaped the fireplace is going to burn only slightly faster than a platform framed house, and the main determinant is not going to be the framing but things like fire-resistant doors and wall finishes.

Sort of, yes. They knew that they had to prevent water so you tend to see homes with larger eves than post WW2 homes. You'll also see attics with windows which seems weird until you realize that was designed to prevent condensation. Also they built homes much smaller (the average home was less than 1000 sq feet 100 years ago, today it's 2400) and they tended to have smaller, compartmentalized rooms. This allowed for the inefficient home to use less energy anyways. Where I live there are quite a few ~120 year old homes that are about 2400 sq feet. These would have been built by fairly wealthy people of that time as evidenced by old directories which indicate a live-in servant at most addresses, rift sawn moldings and floors, and stained glass windows on landings/in dining rooms. And although inefficient, they are smaller so they use similar amounts of energy to much larger modern homes.
