-Install "Energy Star" double/triple pane gas filled windows.
This tends to cost a lot up front, and it may take years to recoup
your cost.

Depends on your location. In the deep South or anyplace without a true
winter season, double or triple pane windows are unnecessary -- in fact, a
waste of money. Double pane windows are good insulation across a
temperature differential. In the north you may have a 50 - 60 degree
differential, for days on end. In the South, even in the peak summer
season
the most differential you'll probably EVER see is about 15 degrees, and
then
for only a portion of the day. What you really need is a window which
blocks radiation, which can be single pane, and a house design with a
large
overhang to keep the windows in shade. Regards --.



Don't know where you got the 15 degree thing. A few days ago it was 105F
midafternoon, 69F at dawn next day. Indian autumns here may have the 15
degree range, and only if it rains all day.

UV and infrared blocking is easily done on 3 pane gas-filled windows.
There's even stick on films for those already installed without. Trees, a
minimum distance away from the house for disaster felling concerns, can
provide natural shading in a.m./p.m for east/west windows..

A house with an extensive overhang is asking to be pulled off in heavy wind
conditions. A full wraparound porch, or half wrap that faces the south, is
smarter. 12" overhang / soffit is enough.
