Want to Do an Energy Evaluation on Your Home? Use this Checklist

Want to Do an Energy Evaluation on Your Home? Use this ChecklistEven though American homes are becoming increasingly energy efficient these days, there’s still lots of room for improvement in most households. Most homeowners are more than willing to invest in improving energy efficiency, both for altruistic and financial reasons. The main obstacle isn’t a lack of will but rather knowledge about what needs to be done. That’s where a home energy audit comes into play. A professional energy evaluation will reveal where energy is being lost in the home, and then tell you how to stop it.

What’s Involved in a Home Energy Evaluation?

  • The energy auditor(s) will inspect your home, checking out likely spots for energy waste, such as windows, doors, and the attic. He or she will inspect your heating and cooling system, including the ductwork. He or she will likely ask to look at previous years’ utility bills to better understand energy usage in your home and detect any patterns over time.
  • Diagnostic tests are undertaken to confirm where energy is being lost. The most common is the blower-door test. A powerful fan and housing is installed in a main exterior door frame, after all windows, doors, and vents have been closed. As the fan blows outward, it depressurizes the house. A gauge measures how quickly air rushes back into the home via air leaks. This measures your home’s airtightness.
  • During the blower-door test, the auditor, using thermographic scanning equipment, will detect where air is leaking, plus locate where insulation is insufficient.
  • A test similar to the blower door also may be done inside your ductwork, to determine how much air is leaking during the heating and cooling process.

After the evaluation, you’ll receive a detailed report listing areas of improvement. While some of the recommendations will be tasks that you can do yourself, other recommendations, such as replacing windows, repairing ducts or upgrading HVAC equipment, will require professional help.
