Exhaust ventilation at night works by using fans or other mechanical systems to remove stale air and pollutants from the indoor environment. The fans draw the air out of the building and expel it outside, creating a negative pressure that encourages fresh air to enter through open windows or other intake points. This process helps to improve indoor air quality and maintain a comfortable and healthy environment for occupants during the night. **
