I took the survey and got a 90% result. There was no place on the survey to show that we have solar panels for all our energy needs and that we have a geothermal heat pump. I am certain that our house would be at 99% efficiency if this survey had included those items.
I have helped many people get home energy audits over the last 3 years and many of them have gone on to have their homes weatherized. I recently helped host an information session with NeighborWorks HeatSquad on cold climate heat pumps and 40 people attended.
We have given tours of our net zero solar home to over 200 people to show them what is possible and I know some of those people have gone on to install either solar electricity in their homes. It is fun to inspire others to either retrofit their homes or to design their new homes with efficiency in mind.
