What does the process of negative air pressure achieve in a building?

1. Increase energy efficiency

2. Depressurize the air quality

3. Enhance air circulation

4. Control moisture levels

The correct answer is: Depressurize the air quality

The process of negative air pressure in a building is primarily used to depressurize the environment, which helps in controlling airborne contaminants and minimizing the spread of pollutants. By creating a difference in air pressure, negative air pressure serves to draw contaminated air away from areas where mold or other hazardous materials are present, preventing their migration to other parts of the building. This containment strategy is essential for effective mold remediation and restoration efforts, ensuring that potentially harmful spores or particles do not escape the contaminated area. While negative air pressure can have implications for energy efficiency and moisture control, its primary function is related to air quality management. Enhancing air circulation is not a direct purpose of creating negative pressure; rather, it may lead to a more efficient flow of air into the space due to the induced pressure difference. Controlling moisture levels may be influenced indirectly through the management of air quality, but the core achievement of negative air pressure is to actively manage contamination within the environment.
