Blending the Art and Science of Building
This comparison is between our 2008 Central Ohio BIA Parade of
Homes “green” home and our 2007 Buckeye Valley Parade of
Homes house.  Both homes are ranches with finished basement
(the 2007 has a walkout basement).  Both homes have gas
furnaces and water heaters.

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!
