How to Reduce Energy Costs in Existing Homes

What Makes the Meter Spin? 40% Heat/Cool, 20%WH, 20% Appl, 20% MiscEnergy use in most Florida buildings 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 50% if the most efficient technologies are employed in new buildings or where existing buildings are very inefficient.

Total annual electric and gas energy use typically falls into four categories: heating and cooling, water heating, kitchen laundry, and lighting and plug-ins. Utility bill costs the average Florida homeowner five percent of their total annual after-tax income. Floridians are currently paying about 12 cents per kilowatt hour (kWh) for electricity. Without close monitoring, electrical use can easily push utility costs over $150 per month.

Thinking About Buying a Home?

If you’re thinking about buying a home, consider getting an energy rating. Before you sign a contract, learn more about home energy ratings. Like a miles-per-gallon sticker for your car, energy ratings give new and existing home buyers a marketplace yardstick that measures the benefits of energy efficiency.

Download the “Thinking About Buying a Home” brochure that explains the benefits.

What is a Home Energy Rating?

Workplace of architect with floor plans photoSimilar 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 Residential Energy Services Network (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.
