In hot and dry climates, how should a building be oriented?
- ALong walls facing north and south to minimize heat gainCorrect
- BLong walls facing east and west to maximize sunlight
- CCompletely closed to minimize air movement
- DOrientation is not important in hot climates
Solution
Concept
Orientation in hot-dry climate
Step-by-step solution
1. Long walls facing north and south reduce solar heat gain.
Explanation
East and west walls receive intense low-angle sun.
Why the other options are wrong
The other options increase heat or ignore orientation.
Shortcut
Hot dry: long walls N-S.
Correct answer: A) Long walls facing north and south to minimize heat gain
