Which ancient architectural technique used in Gujarat is known for enhancing indoor thermal comfort by providing excellent thermal insulation and is still relevant in modern green building design?
- AHigh ceilings
- BJali (lattice) screens
- CCourtyards
- DThick mud wallsCorrect
Solution
Concept
Thermal insulation in traditional building design
Formula
NONE
Step-by-step solution
1. Thick mud walls possess high thermal mass, significantly delaying heat transmission during daylight hours. 2. This natural thermal insulation property provides superior indoor climate control in hot and dry regions. 3. Therefore, thick mud walls offer optimal indoor thermal comfort and remain relevant in sustainable architecture. Answer: D
Explanation
Thick mud walls possess high thermal mass and low thermal conductivity, which delays the transfer of outdoor heat into the building interior. This keeps the living spaces cooler during hot daytime hours and retains warmth during colder nights. Thus, thick mud walls provide excellent thermal insulation to enhance indoor comfort, making option D correct.
Why the other options are wrong
A) High ceilings facilitate air circulation rather than providing direct thermal insulation. B) Jali screens enhance ventilation and shade rather than providing thick thermal insulation. C) Courtyards induce natural ventilation and passive cooling rather than insulation.
Shortcut
Thick mud walls = High thermal insulation for indoor thermal comfort.
Common mistake
Choosing Option B (Jali screens) or Option C (Courtyards) by confusing general passive cooling techniques with the primary insulation provider.
Correct answer: D) Thick mud walls
