Recommended Orientation of Abattoir Long Axis
View Complete Answer & Explanation
Question (English)
The long axis of an abattoir should face in which direction?
- East or West ✓ Correct
- North or South
- North or East
- North or West
Explanation:
Correct Answer: East or West
The long axis of an abattoir building should face in the East–West direction. This orientation ensures that the broad sides (longer walls) face North and South, maximising natural ventilation and minimising direct solar heat gain through the walls, which helps maintain lower temperatures inside the slaughter hall and chill rooms.
Why East–West Orientation?
- In the Northern Hemisphere, the sun moves East → South → West across the sky.
- Orienting the long axis East–West means the large wall surfaces face North and South — receiving less intense direct sunlight than if they faced East/West.
- This keeps the interior cooler, crucial for meat hygiene and microbial control.
