all possibilities
All prerequisites must be met for a given
rating system

Home Size Adjustment30
Compensates for the effect of home size on
resource consumption…smaller homes with
more bedrooms are better
1. Calculate square footage using American
National Standards Institute (ANSI) Z765
All directly conditioned square footage, finished
and not finished, that meets building code
requirements for living space
Home Size Adjustment31
2. Determine number of bedrooms.
It is in your best interest to count the most rooms.
“any room or space that could be used or is
intended to be used for sleeping purposes and
meets local fire and building code requirements.”
If in doubt, consider if the room would be used as
a bedroom if another family member or affiliate
moved in. (new baby, nanny, grandparent,
exchange student, etc)
If five bedrooms or less, consult the following
table.
Home Size Adjustment32
Home Size Adjustment33
If home is larger than the size shown in the
bottom row of the applicable column, refer to
the following chart to estimate the threshold
adjustment or to Equation 1 to calculate the
adjustment:
