Principles of Building Planning MCQ with answer and solution

Concept

Preferred aspect for a verandah

Formula

NONE

Step-by-step solution

1. Verandahs serve as protective sun-shades for living spaces against intense heat and driving rain. 2. Orienting a verandah toward the West or South-west blocks harsh afternoon sunlight from directly heating inner walls. 3. Therefore, a better aspect for a verandah is west, sw. Answer: A

Explanation

A verandah facing west or south-west acts as a protective buffer, shielding the interior of the building from harsh afternoon solar radiation. This placement reduces indoor temperatures and lowers cooling needs during warm periods. Therefore, a west or south-west aspect is ideal for enhancing thermal comfort in building design.

Why the other options are wrong

B) NW aspects receive harsh afternoon sunlight and offer poor breeze during hot weather. C) NE aspects capture light morning sun and are better suited for bedrooms or study rooms. D) SE aspects receive morning sun and are typically preferred for living rooms or kitchens.

Shortcut

Verandahs face West/SW to block direct, harsh afternoon sunlight.

Common mistake

Choosing North East or South East based on standard living room aspect guidelines rather than West/South West.
