Final answer:
The use of mechanical ventilation increases control of air flow and speeds the removal of contaminants, enhancing indoor air quality by replacing indoor air with filtered and conditioned outdoor air. The correct answer is option C. Speeds the removal of contaminants
Step-by-step explanation:
One advantage to using mechanical ventilation is that it increases control of air flow into and out of a building. Mechanical systems allow for the management of air exchange rates, ensuring that indoor air is continuously replaced with filtered and conditioned outdoor air. This advantage is particularly useful in managing the quality of indoor air, especially in terms of speeding the removal of contaminants that can accumulate in poorly ventilated areas.
Mechanical ventilation systems, such as exhaust fans and ductwork, provide a methodical way of removing indoor air pollutants and controlling humidity and temperature levels within a building, thus enhancing the overall indoor environment. These systems are crucial in maintaining healthy air quality and preventing the buildup of harmful pollutants that can result from inadequate natural ventilation or infiltration.
