Natural Ventilation

Natural ventilation in buildings production is obtained with natural circulation of air entering through the side openings ( opening windows or curtains) and out through the top opening generally located at the roof ridge. Ventilation is more lively when the greater the difference of external and internal temperature is greater when the difference in height between the openings of entry and exit of air. Clearly therefore it is relatively easy to obtain good ventilation in the winter period compared to the summer.
