Window Replacement in Florida: What To Know

Because of its climate, Florida windows primarily require cooling features. The Sunshine State's average annual temperatures range from 77 to 85 degrees Fahrenheit for the highs, and from 56 to 73 degrees Fahrenheit for the lows.

Therefore, ENERGY STAR-rated, energy-efficient replacement windows in Florida need a U-factor, the rate of heat loss, of ≤0.60. They also need a solar heat gain coefficient (SHGC), the fraction of solar radiation infiltrating a window, of ≤0.27. In warm climates, like that in Florida, a low SHGC is the most important consideration when selecting replacement windows. The lower the SHGC, the lower the amount of solar heat infiltrating the window.

This would yield a tax credit of greater than $1,000 for either window type.
