This occupancy is a use of a building by people gathering for the purpose of civic, social, religious function, recreation, food and drink consumption, or waiting for transportation. This gallery offers example images of public entry and exiting, air conditioning and lighting, and audience seating. The examples presented possess a high degree of acoustical sensitivity and concern for noise control, but many buildings exhibit much less demanding environments. Small spaces and occupancy loads qualify for certain exemptions, these photos in performing arts centers and places of worship represent many structures common in the modern building environment.
