To add to this: large windows seem great on the surface, however in Nordic countries, the houses are generally very well insulated and rarely have air conditioning, so the new houses with floor to ceiling windows turn into unlivable greenhouses in the summer.

I find this hard to believe. I live in a place with tall (not quite floor to ceiling) windows and hot summers and having such large windows gives the house way more ventilation, not less.

I remember a apartment where I live as student. First floor next to bus stop, west fasting windows. So not really that great to open. And the central ventilation itself was not that effective. Net result was 27C inside in mid winter...
