The front of my house faces southwest. On a sunny afternoon, when it is freezing outside, my house is well enough insulated that the sunlight entering through my front windows and storm door can raise the temperature inside by several degrees Fahrenheit. By closing the prime front door, and covering my windows with insulated plugs, it takes several hours to lose those degrees of heat.
