Q: Is an energy evaluation of my home worth my time?

A: Depending on where you live, the age of your home, and how you use and receive energy, knowing how efficient your energy use is can potentially save you money on cooling and heating bills. Features like poorly performing windows and doors, lighting, and electronics can make a big impact on energy efficiency.

Most of us have been spending more time at home as a result of COVID-19, giving us the opportunity to reflect, clean, evaluate budgets, and consider home improvement projects. One oft-forgotten item on the list is checking your home’s energy efficiency.

DIY or go with a pro?

Home energy evaluations can be done on your own, using guidelines from sources such as your utility service company, or you can hire a professional to perform one. Either way, home energy assessments evaluate your home’s current energy consumption and then identify energy efficiency measures.

Poorly performing windows and doors are one of the main reasons for energy loss—sometimes as much as 30%—so an energy evaluation will often start there. Not taking proactive energy efficiency measures can feel as if you’re throwing money right out the window!

Out with the old, in with the new

Depending on a variety of factors, replacing poorly performing windows and doors may be recommended. Besides cutting your utility bills and reducing energy loss, new windows and doors can help control moisture in your home, improve your home’s curb appeal, and increase the value of your home. And if you install new windows and doors this year, you may even be able to take advantage of tax credits to bring down the cost of your project—federal tax credits for these and other home improvement projects have been extended until December 31, 2020.

If you go the installation route, be sure to consider energy performance ratings as you shop around. Look for Energy Star labels or visit energy.gov for information on performance ratings. Choose the most efficient windows and doors you can afford and those that work best in your climate.

Always work with an experienced installation team; windows and doors need to be installed according to manufacturer’s instructions, other¬wise your warranty may be void. Using recommended flashing and caulking methods also provides maximum energy efficiency and prevents uncomfortable drafts.

Reduce, Reuse, Repair

If your existing windows and doors are in good condition, an energy evaluation may instead give you guidance on how to reduce energy loss and improve the overall performance of your windows and doors.

Saving energy may be as simple as adding shade protection to the interior or exterior of your home. Guidance may also include checking each window for air leaks and operation issues. Look for moisture, condensation, or other signs of mold on and around your windows and windowsills. Regularly check caulking, as well, as failed seals between glass panes can fog window surfaces. Failing windows don’t just lead to costly utility bills—a lack of moisture control can negatively impact your family’s health.

Aside from suggestions for maintaining windows and doors, an energy evaluation can identify energy efficiency issues with other items, such as insulation, ventilation, heating and cooling systems, lighting, and appliances. Many of these suggestions are simple and don’t have to be costly.

In short, yes, it’s worth the time to do an energy evaluation to keep your bills low, your home safe, and your family healthy.
