Energy use in virtually any Florida building can be cost-effectively reduced by at least 15-30%, saving owners thousands of dollars over the life of their buildings. With skill, building energy use can be reduced by as much as 60-75% if the most efficient technologies are employed in new buildings or where existing buildings are very inefficient.

What is a Home Energy Rating?

Similar to a miles per gallon (mpg) rating for your car, a home energy rating grades the energy efficiency of your house.  This value is calculated using the Home Energy Rating System (HERS), developed by ResNet.  An energy-efficient home has lower electricity bills and you create a smaller carbon footprint.  Many homes can benefit from energy efficient improvements, some of which have a payback period of only a few months.
