Principles of Building Planning MCQ with answer and solution

Concept

Minimum window area requirement for classrooms

Formula

NONE

Step-by-step solution

1. Adequate natural lighting and ventilation are essential factors in designing educational spaces. 2. For classrooms, window opening areas are defined as a percentage of total floor area. 3. According to standard planning norms, the minimum window area required in a classroom is 20% of floor area. Answer: C

Explanation

Adequate daylight and fresh air are crucial in learning spaces to maintain comfort and health. Building planning regulations mandate that openable window areas in classrooms should equal at least 20% of the floor area to ensure proper lighting and air exchange. Consequently, 20% of floor area is the correct minimum requirement.

Why the other options are wrong

A) 10% of floor area is the general minimum for residential rooms, which is insufficient for educational spaces. B) 15% of floor area does not satisfy the natural lighting requirements for classrooms. D) 25% of floor area exceeds the standard minimum percentage required by building codes.

Shortcut

Classrooms require window ventilation area equal to 20% of floor area.

Common mistake

Confusing classroom window opening requirements (20% of floor area) with general residential ventilation requirements (10%).
