Questions
1. The left side (garage side) of the dwelling unit has a setback of 2 metres (6’ 6”), and
the fire department is within 10 minutes response time. The exposed building face for this
side is 71 square metres. What is the maximum aggregate of glazed opening permitted in
this wall? (For this exercise, increase to the next highest square metres of exposed
building face that the Code gives and do not use Part 3.)
Answer The maximum area of glazed opening that is permitted for this exposed
wall is 9% of the total area of the exposed wall. That means that the
maximum permitted opening is 9% of 71 square metres which equals to
