When I bought this house 20 years ago (wow doesn't seem that long)
I planted aspen trees on the south side of the house along a big concrete
driveway that used to be a bare area of concentrated solar heat. The trees are
mature and have added Mountain Ash and chokecherry that the birds "planted".
Having that shade on that driveway and side of the house
in the summer helps, but the West side in the afternoon really
gets a solar beating.
