I disagree. The window insulation requirement is based on
temperature difference between the outside temperature and the desired inside temperature. Up north, it may be 0 degrees outside and 70 degrees inside. That's a temperature difference of 70 degrees. You definitely need double-pane windows for a 70 degree temperature difference.
Down here in Florida, the "winter" is so mild as to make thermopane windows unnecessary. As for the summer cooling, it seldom gets hotter than about 95 degrees, and that's only for a few hours per day in the hottest part of the summer.
Your temperature difference then is only about 17 degrees if you keep the inside at 78 degrees.
Many people would argue that thermopane windows are unnecessary for a mere 17 degrees temperature difference. My 2,400 square foot house has single pane windows, including my enclosed lanai, and my heating and cooling bills are very modest even during the hottest part of the summer.
In short, Leesburg is not Minneapolis.
