Episode 12 Summary

⚡️WHY DID THIS HOMEOWNER GET THE ENERGY AUDIT? Homeowner's exact reason: This family was feeling uncomfortable in their new home and they had a good experience in Nevada with an energy assessment, so they decided to do the same when they move to Maryland in November 2022.

⚡️WHERE WAS THIS HOME ENERGY AUDIT? This audit was done at an interior townhouse located in Silver Spring, Maryland, 20902, through the Pepco Home Performance with ENERGY STAR® program.

⚡️WHAT MADE THIS ENERGY AUDIT INTERESTING? This energy audit yielded a neat find in the basement that showed that the house was losing energy due to the stack effect - in normal conditions. In other words, I did not have to run the blower door test to show air leakage in this house!

⚡️WHAT YOU MAY LEARN FROM THIS ENERGY AUDIT? In this instance, the customer had spent a good amount of resources to put a plastic seal around a hard-to-reach window and the house had a much bigger problem and one that is easier to fix, hiding in plain sight.

⚡️KEY TAKEAWAY FROM THIS HOME ENERGY AUDIT: Dark, discolored insulation is a tell-tale sign that air leakage is occurring in that location.

There are so many houses that I have been to for an energy audit where during the beginning walk through the owner is super focused on windows and doors. I know the reason for this. It is because it is the only possible place you can see any cracks and crevices that lead to the outside.

But, there are far worse offenders than those two areas, usually hiding in plain sight.

Hello and welcome to my world which revolves around teaching some of the basics of building science so that more people can get into the driver’s seat regarding their energy usage and overall comfort around the house.

Weekly episodes should yield a variety of housing types that will provide both common and unique scenarios. 

As always, finding the correct diagnosis will require good investigative work, experience, and the use of diagnostic equipment.

Hopefully, these daily encounters will help open people's minds to the subtle, yet important ways in which a home can lose, literally "tons" of energy.

Do you have some other issue not covered here?

Often times homeowners don't know what a home energy audit is or how it can actually help you understand energy waste in "three dimensional" ways.

For example, it is quite likely that a set of poorly sealed recessed lights will cost you far more in annual energy waste than perhaps all of the windows in your house.

Here is what the Home Performance with ENERGY STAR® program can do for you:

1.  It can help you avoid choosing the wrong solution to a comfort problem you are having around the house.

2.  An energy audit can help you find practical & often missed ways to reduce your energy bill.

3.  A home energy audit is a great way to organize your home improvement priority list.

4.  It will undoubtedly guide you, or someone you know, to a more comfortable home.
