Guide based on normal
room insulation, average
number of sun exposed
windows and two person
occupancy.
1. If heavily shaded, reduce
cooling Btus required by 10%
2. If very sunny, increase cool-
ing Btus required by 10%
3. Add 500 Btus per person over
2 people
4. Add 4,000 Btus if the area is
a kitchen
