Solution
Concept
Minimum ventilation area for hospital wards
Formula
NONE
Step-by-step solution
1. Hospital wards require adequate ventilation to prevent nosocomial infections and maintain air quality. 2. Building codes prescribe minimum opening areas for windows and ventilators based on room floor area. 3. For hospital wards, the minimum ventilation area required is 20% of floor area. Answer: B
Explanation
Hospital wards require high ventilation rates to maintain clean indoor air and minimize healthcare-associated infection risks. Building codes specify that the minimum openable window or ventilation area in hospital wards must be 20% of the floor area. This ensures adequate fresh air exchange for patient recovery.
Why the other options are wrong
A) 10% of floor area is insufficient for hospital wards where higher ventilation rates are mandatory. C) 25% of floor area exceeds the standard minimum requirement for hospital ward ventilation. D) 30% of floor area is significantly higher than the required regulatory minimum threshold.
Shortcut
Hospital wards require a minimum ventilation area of 20% of the floor area.
Common mistake
Confusing hospital ward ventilation requirements (20% of floor area) with standard residential building regulations (10%).
Correct answer: B) 20% of floor area
