I see Ben has made some updates to the energy tracker. I think its getting close to being useful.
I suggest adding another field for "Renovations & Improvements" where you can list things you've done to the house. Also, it and the notes field don't recognize returns, so it slaps everything on one line. Both of these fields need to be larger than the current notes field.
Also, when you view a specific home it doesn't show the date, HDD, CDD, or notes field for each entry.
