Gosh ST, I can't hardly go from room to room without taking my jacket. I don't always wear it - but we don't have central heat here, and there's parts of the house where the drapes billow when the wind blows. (I been workin' on that.)
I changed all my windows on the north for just that reason. In reality though, I should have changed all the ones on the south and east because that is the predominant wind direction.
