Good comments Kermit. Only proviso I would add, from my Architecture training, is the phychological and physiological aspects of our built environment. We are very sensitive to light and sound, just as we are heat and humidity. Yes apartments have a better surface to volume ratio that gives benefits for space heating, but at what cost?
Apartments can be designed well, but you need light from two sides of every room. They should be no taller than four levels, living or working higher than that comes with an increased risk of mental illness with each level higher. There are more guidelines, a good read is "A Timeless Way of Building" by Christopher Alexander. For someone that has been living sustainably for decades, check out this friend of mine from Dunedin, New Zealand. https://powerdownkiwi.wordpress.com/ Murray is a fridgy by trade, yet his reputation sees him guest lecture on the topic at Otago University. He isn't one to mince his words. Cheers all.
