Has anyone heard of these homes or know of someone that has one? They sound very interesting. www.enertia.com I emailed them for a list of previous homeowners so I could ask if they were satisfied. They said they get 150,000 request a year and their homeowners said they had enough hassles. They said they build display models and I could visit one they are building in Green Bay (the closest one to me, although several hundred miles). If you know of anyone that has built one or have heard of these homes before, please let me know. Thanks.
