In light weight panelized roof configurations, Ceiling Joists spacing is what?

Explanation:
In lightweight panelized roof setups, ceiling joists are typically spaced widely at 24 inches on center. This spacing fits with the panelized design, where the roof panels and bearing walls carry much of the load, and the ceiling joists mainly serve as a ceiling tie and finish support. Using 24" OC reduces the number of joists, saving weight and material while still providing enough stiffness to keep the ceiling true and to help transfer loads. Smaller spacings like 16" OC or 12"/8" OC would add unnecessary members and weight for this type of construction. Hence, 24 inches on center is the standard.
