Natural Ventilation Isn't the Most Efficient Solution in All Cases

Ventilation serves two main purposes in a room: first, to remove pollutants and provide clean air; second, to meet the metabolic needs of the occupants, providing pleasant temperatures (weather permitting). It is well known that environments with inadequate ventilation can bring serious harm to the health of the occupants and, especially in hot climates, thermal discomfort. A Harvard University study demonstrated that in buildings with good ventilation and better air quality (with lower rates of carbon dioxide), occupants showed better performance of cognitive functions, faster responses to extreme situations, and better reasoning in strategic activities.

It is not difficult to see that ventilation plays a vital role in ensuring adequate air quality and thermal comfort in buildings. We have all felt it. But when we talk about ventilation, a light breeze from the window might come to mind, shifting through our hair and bringing a pleasant aroma and cooling temperature that brings fresh air and comfort. In mild climates, this experience can even be a reality on many days of the year. In harsh climates or polluted spaces, it could be quite different.
