Why is it important for a building to have emergency lighting?

Emergency lighting is crucial in any building as it provides essential illumination during power outages or emergencies. When standard lighting fails due to an electrical issue or during a critical situation, effective emergency lighting ensures that occupants can see their surroundings and navigate safely. This visibility is vital for facilitating safe evacuation, reducing the risk of accidents, and helping individuals locate exits and safety equipment. By maintaining adequate lighting, emergency systems enhance overall safety and manageability within a building during unforeseen circumstances.

The other options, while they may have their own relevance in different contexts, do not align with the primary purpose of emergency lighting. Enhancing aesthetics or improving security does not address the immediate need for visibility in emergencies. Likewise, reducing energy consumption can be a goal of many building systems, but it is not a factor that directly relates to the purpose of emergency lighting in ensuring safety and preparedness during crucial moments.
