Episode 13 Summary

⚡️WHY DID THIS HOMEOWNER GET THE ENERGY AUDIT? Homeowner's exact reason: The owners of this home wanted to make sure they were doing what they can to keep energy bills down and the house comfortable.

⚡️WHERE WAS THIS HOME ENERGY AUDIT? This audit was done at an interior townhouse located in Rockville, Maryland, 20851, through the Pepco Home Performance with ENERGY STAR® program.

⚡️WHAT MADE THIS ENERGY AUDIT INTERESTING? It was a good exercise for this family to compare the things that they were doing around their home to the things on the energy assessment list to see where there were gaps and opportunity for improvement.

⚡️WHAT YOU MAY LEARN FROM THIS ENERGY AUDIT? Storing items in the attic on top of flooring is not a good idea and a lot of times we find huge gaps and holes in an attic during the process of working in the attic even after the initial assessment.

⚡️KEY TAKEAWAY FROM THIS HOME ENERGY AUDIT: There is no substitute for creating a more efficient and comfortable home than addressing the air sealing and insulation in the attic and often times it will yield incredible air leakage reduction numbers which means you will live in a more comfortable home and spend less doing it!

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.
