This is a view of the
left side of the house with the front on the right
and the rear on the left. Note the attic vent type
and size, the vent size is determined by the square
footage of the house. Use the square footage of
the house divided by 150 to get the square footage
of the vents needed. Take the square footage of
the livable area and the garage “1788”
for total attic space, divided by 150 for a total
of approximately 12 square feet of vent opening
required. The vent size given is only 5 square feet
times two vents for a total of ten square feet.
We come up a little short. We will need another
2 square feet.
Note that the house is raised above the natural
grade of the lot. This is to provide adequate drainage
away from the house.
