Thank you gfmucci for the Energy star Link.
Basically To earn the ENERGY STAR, a home must meet guidelines for energy efficiency set by the U.S. Environmental Protection Agency. These homes are at least 15% more energy efficient than homes built to the 2004 International Residential Code (IRC), and include additional energy-saving features that typically make them 20–30% more efficient than standard homes.
More detailed info is found at that link

I have a feeling that the homes in the Villages do not meet all the standards to be Energy Star because the Villages used Builders grade equipment furnaces water heaters refrig dishwashers low efficient windows etc. This is not a dig on the Villages just what a builder does to increase profits.
So my Question to you is......Do you feel your home is a well constructed energy efficient home AND what would you do to improve your home's construction or energy efficiency.
Did your improvement result in any Dollar savings.
