The Science Behind Attic Airflow and Energy Savings
Living in Old Hickory, TN , you understand the importance of keeping your home cool year-round. Proper attic ventilation play a crucial role in energy efficiency , especially in our local climate conditions .
Ventilation systems function by promoting air circulation that removes hot air from your attic space. During summer months , roof spaces can exceed dangerous levels, which makes your air conditioning to consume more energy.
The fundamental principle of attic ventilation involves creating a continuous airflow system that removes hot air from your attic space while drawing in cooler outside air. This process, known as the stack effect, occurs naturally when intake vents (typically located in soffits) allow cool air to enter while exhaust vents (like attic fans or ridge vents) remove heated air. For 37138 residents, this system is particularly important due to our regional climate patterns and seasonal temperature variations.
