This is actually the back of the house. The lower windows are my room and the upper windows are where the domestic employees sleep most nights (they have homes that are fairly far away, I understand). You can also see a big white wall rather than open sky- in this neighborhood the buildings all butt up against one another. The picture is taken from a little patio under an awning.

You might be able to tell that the 'hall' to the student rooms and the employee rooms are open, which is a pretty common design. When it's hot enough for Peruanos to complain it's only in the 80's or so, and it never freezes in winter. Its rare-issimo to have any kind of climate control machinery anywhere. On that note, I also notice that lawn and garden care are done with hand operated tools, like those lawn-mowers that spin when you push them- not gas operated- which is almost surprising cause gas is cheap.
