Why is it advantageous to maintain a positive pressure in a building?
A. To reduce exfiltration
B. To reduce drafts
C. To minimize system ventilation heat load
D. To simplify system fan and duct design
Answer (2)
Maintaining a positive pressure in a building primarily helps to reduce exfiltration, which prevents energy loss and improves indoor air quality. This condition minimizes drafts and keeps conditioned air within the space. Thus, the best answer to the question is option A. To reduce exfiltration. ;
The primary advantage of maintaining positive pressure in a building is to reduce exfiltration, which prevents energy loss and improves indoor air quality. This condition also helps reduce drafts and supports efficient operation of heating and cooling systems. Therefore, the correct choice is option A: To reduce exfiltration.
