In the context of building codes, what does 'egress' refer to?

Egress refers to the exit routes from a building, which is a critical aspect of building safety and design. It ensures that occupants can safely and effectively exit a structure in emergencies, such as fires or other hazardous situations. Egress requirements are governed by building codes to specify the number of exits, their width, accessibility, and overall design to accommodate a certain number of occupants. Clear egress paths are vital for life safety and are a key focus in construction and building modifications.

In the context of the other options, materials used in construction pertain to the types and specifications of building components, while the design of indoor spaces relates to how internal environments are arranged for functionality and aesthetics. Landscaping around a building concerns the exterior aesthetics and use of surrounding open spaces but does not inherently affect the escape routes essential for egress. Understanding egress is fundamental for ensuring compliance with safety regulations and protecting occupant safety.
