Assess the energy efficiency of your home and see how it measures up:

Nexus Energy Center’s AlabamaWISE program is the only registered provider of Home Performance with ENERGY STAR certifications in the state of Alabama. AlabamaWISE participants are ensured of improved home energy performance. But first, you need to know how well your home is currently performing.

EPA’s Home Energy Yardstick provides a simple assessment of your home’s annual energy use compared to similar homes. By answering a few basic questions about your home, you can get:

  • Your home’s Home Energy Yardstick score (on a scale of 0 to 10);
  • Insights into how much of your home’s energy use is related to heating and cooling versus other everyday uses like appliances, lighting, and hot water;
  • Links to guidance from ENERGY STAR on how to increase your home’s score, improve comfort, and lower utility bills; and
  • An estimate of your home’s annual carbon emissions.
