The Exterior (part 2)
The Exterior
Windows are a significant source of heat loss on most homes. Windows
should be double pane. If yours aren't, and you can't afford to replace
them just yet, consider installing storm windows. Shutters will also
provide insulation. Obviously, the better the shutters fit, the better
the insulation. And awnings on south-facing windows can be used to minimize
the summer sun, helping reduce the inside temperature without using
energy to do so.
Closely planted shrubs or a sturdy fence can protect the house from
the wind and can help reduce your winter heating load. Shade trees planted
on the south side of the house block the summer sun. Also, vines help
keep a house cool in summer and warm in winter.
