Low E double windows are
covered with Plexiglas storm windows in winter |
Windows are
good for gaining heat on a sunny winter day but aren't good for heating
on a winter night. Solar energy
from the south-facing windows provides the house
with natural heat in the winter. Adequate roof overhang provides
protection from the sun's heat in the summer. 56%
of the windows are located on the south side of the house and 27% on the
east side. The windows also
reflect heat back into the house in the winter and reflect heat out in
the summer. A skylight has four panes of glass to conserve energy.

On cold winter nights our double-hung
windows are insulated with window panels |

Foil is used
in the top part of the window because the air space between the inside
window and the Plexiglas storm window is less than 1 inch
and there is only enough space for the heat to be radiant. Since
the heat is radiant, it can be reflected back by using foil
insulation. The lower part of the window has an air space of over
2 inches between the inside window and the Plexiglas storm window, which allows convection to take place and requires insulation
to stop the air flow--such as the 2-inch foam used here.
