East or West?

I might find myself in the position of choosing between two apartments that are identical except that one faces east and the other faces west.

There are two primary factors involved: sun and wind.

East gets more sun in the morning, West gets more sun in the afternoon. East would be better for my cicardian rhythms and marginally better both in winter and summer insofar as sunlight will warm my apartment (in the winter I'd rather have warmth in the morning, and in summer I'd rather have coolness at night). West would allow me to enjoy sun-filled rooms for more hours a day (since if I'm home during the day, I'm likely to be asleep in the morning and awake in the afternoon).

The prevailing winds come from the west, so West gets more wind and East gets wind only rarely. Wind is very very good in the summer (helps cool and freshen the apartment naturally) and marginally bad in the winter (seeps in and makes things colder). Less wind might also mean that my windows don't get as dirty on the outside.

If everything functions optimally - my blinds can keep out the sun, my heating and air conditioning work, the windows are well-sealed - the primary factor will be my circadian rhythms (favouring East), with the fact that I like having wind blow into my windows in good weatther (favouring West) coming in a not-close but not-distant second.

If my air conditioning stops working, wind becomes far more important (favouring West) and sun somewhat more important (favouring East). The air conditioning system is new, which reduces the chance of age-related difficulties but increases the chance of teething troubles.

Other things that can go wrong have a more marginal effect. The biggie is presence or absence of air conditioning. I guess it's also dependent on whether I can turn on my air conditioning at will regardless of the date, or whether the whole building switches twice a year. I don't have this information yet. Being cool in the summer is more important to me than being warm in the winter.

Any thoughts? Would you pick East or West?
