It looks like there isn't going to be a continuation from Spy but some may
be interested in some facts anyway.

These figures are the difference in degrees in the rising position of the
sun between 20th June and 20th December. The difference in setting position
would be similar.

Miami 52
London 79
Moscow 90

Obviously it varies with latitude and the same sort of differences arrise in
the southern hemisphere as in the north. There is considerable difference
in how the sun strikes your house between summer and winter unless you live
in rather low latitudes, basically in the tropics. This is worth
considering when designing the passive solar heating/cooling of your house.

I live at the same latitude as Moscow (and Alaska) and there are plenty
of valley houses here which are sunny all summer, but receive no direct
sun in winter because the sun never gets high enough in the sky. We've
always avoided buying property in winter shadow locations because they are
noticeably colder and darker for half the year.
