59
Q

How is the occupant load of a space calculated?

A

To calculate this value for a space, the total area in square feet (or square meters) is divided by the occupant load factor.

60
Q

What is an exit access travel distance?

A

This is the distance an occupant must travel from the most remote point within a building to the entrance of the nearest exit.

61
Q

In the United States, what document gives jurisdictions the basic authority to adopt and enforce building codes?

A
