Question

why is advantageous to maintain a positive pressure in a building?..a.reduce exfiltration b. minimize system ventilation heat load c. simplify system can and duct design or reduce draft

Answer 1

solution b.minimise system ventilation heat load

ventilation into a building, controls by the positive pressure

Answer 2

Answer:

Maintaining a positive pressure in a building is advantageous because:

1. Reduces exfiltration – Prevents unconditioned outdoor air from leaking into the building, improving energy efficiency and indoor air quality.

2. 
   

3. Minimizes system ventilation heat load – Reduces the need to heat or cool excess incoming air, lowering energy costs.

4. 
   

5. Simplifies system can and duct design – Ensures more predictable airflow, making HVAC system design and operation easier.

6. 
   

7. Reduces drafts – Improves occupant comfort by preventing unwanted air movement from leaks.

8. 
   

Key benefit: Enhances energy efficiency, indoor air quality, and comfort while simplifying HVAC system management.

Final Answer:
$\boxed{{\displaystyle \text{All of the above (a, b, c, and additional benefits)}}}$
