What is the primary purpose of attic ventilation in hot weather?

• A. To relieve summer heat
• B. To prevent moisture in winter
• C. To improve seismic resistance
• D. To reduce noise

Answer: (A)

Attic ventilation in hot weather is meant to remove the hot air that builds up in the attic. By letting hot air escape and bringing in cooler outside air, the attic temperature drops, which helps keep the living spaces cooler and reduces the air‑conditioning load. Moisture control is more relevant in winter, and attic vents don’t affect seismic resistance or noise, so those aren’t the primary purposes in hot weather.
