What is a potential consequence of an increase in occupant load as mentioned in building standards?

An increase in occupant load in a building can lead to a reduction in performance level, particularly concerning safety and building services. As the number of occupants increases, demands on egress systems, mechanical systems, and overall building infrastructure can amplify. This means that existing systems may become overloaded, potentially causing them to operate less effectively. For instance, stairways and exits, which are designed to safely accommodate a specified number of people, may become congested, increasing the risk during evacuations.

Additionally, an increased occupant load could overwhelm fire alarm systems, HVAC systems, and other crucial supportive infrastructure designed for a lower capacity, potentially resulting in safety risks and a lower overall performance level. Building codes and standards take these factors seriously, leading to stricter requirements when occupant loads increase to ensure safety and functionality are maintained.
