Working daily within the parameters of the ENERGY STAR®  program you have to dive deep into the inner workings of how a house is built and where to look for past shortcomings that lead to current comfort problems and high energy bills.

The attic, crawl space and even sometimes the basement are the least visited places inside a home.  But, if left unchecked they can yield some of the biggest problems that are actually easy to fix.

I decided to record some of my experiences beginning November 2020.  I hope you find something that helps you. 

You don't really know what is happening in these spaces unless you get in there every so often and take a look.

The BGE/Pepco Energy Audit Experience

An interview was conducted with a BGE Home Performance with ENERGY STAR® Program participant located in Howard County Maryland.

Questions asked:

1. What made you decide to the get the energy audit?
2. Did you get anything from the energy audit that you were not expecting?
3. What recommendations did you follow and why?
