What is a key function of an exhaust system in a building?

The key function of an exhaust system in a building is to capture and remove air pollutants. This system plays a vital role in maintaining indoor air quality by drawing out stale air, smoke, odors, and harmful contaminants such as volatile organic compounds (VOCs), gases, and particulate matter. By effectively removing these pollutants from the environment, the exhaust system helps ensure a healthier indoor atmosphere for occupants.

Additionally, the removal of excess humidity and airborne toxins is crucial in preventing issues such as mold growth and respiratory problems. This system works in conjunction with other ventilation components to create a balanced air exchange, thereby contributing to the overall functionality and comfort of the building.

While other building systems may contribute to aspects like natural lighting, heating efficiency, or the distribution of cooled air, they do not specifically address the critical need for pollutant removal as the exhaust system does.
