The 2007 home is a very efficient home. It is an Energy Star home that received a rating of
68.0 (meaning the home is 32% more efficient than a home built to code). This home qualified
for the U. S. Governments energy tax credit. This home is more energy efficient than the
new homes most builders offer today!
Both homes were unoccupied during the time the utility bills cover. Since utility prices can
vary over the course of a year, it may be better to look at the actual usage data (Ccf for gas
and KWH for electric).
The results are eye-opening to say the least!
