We (very) generally build with sticks and bricks with uPVC framed double or triple glazed windows. Double skin of bricks externally, one skin internally for load bearing walls and wooden "stud" walls for the rest. However there is a lot of variation after that. Modern building regs stipulate a lot (decent amount) of thermal insulation in roofs and acoustic insulation between floors and rooms if possible. When we had our 1920s build modernised somewhat, we had to have additional steels and wooden structure added to account for potential additional snow loading on the roof because it would no longer melt quickly. Yes, we do get good passive cooling in general with this design. Some better than others. Half of the ground floor (first floor in en_US) of my house is tiled with underfloor heating. The dogs love it when dumping thermal overloading - it is cool to the touch regardless of air temperature. Now, if I wanted to add AC to my house it would not need to account for window shape. I don't understand that comment. Slide up windows are called sash here in the UK and are generally associated with the Victorian era! To add AV I would simply get another consumer unit added to my home 'leccy feed. Then I would fit the internal air out in the primary living area and connect to the external unit by drilling holes in the wall. Not sure where the windows fit into this. Oh and I'd try and fail to get the wife to close the bloody doors. Not going to happen - I'll stick to being British and whine when it gets warm.

The majority of American air conditioning units are window mounted, like these: https://www.consumerreports.org/window-air-conditioners/how-to-size-a-window-air-conditioner/ https://www.consumerreports.org/window-air-conditioners/how-... As an example, the house I grew up in, late 1940s, was piped for heating only, to an oil furnace. When my parents wanted an AC, they got a window unit. (Bonus: The original heating system had ceiling vents, at some points the house was re-vented for floor vents) My place has in floor heating, if I wanted AC there aren't any vents in my house, so same thing, I'd have to get a window unit.

  That is not true most houses built in the US have central AC not window mounted. They might be popular on the West Coast but the majority of house do not have those.

    Most new housing in the US has central AC, but most housing here predates that being standard. In the Northeast especially, window units are very common.
