Changes:

The carbon dioxide content of the air in urban areas, for example, is considerably enhanced by the artificial lighting. But this is still far no reason to extra ventilation, unless there is a larger building, such as Larger conference rooms, theaters, etc., where the carbon dioxide is a product of respiration, and the intense lighting creates a strong warming. Then, of course, a more intensive ventilation will be needed.

Humidity and wind

Also, the humidity affects the continuity of materials. Furthermore, the wind also affects the natural ventilation. For some strong winds will be plenty of air in the room pressed. But this is not of great importance. Not even sensed these transactions. With equipment in the rooms, which produce heat, it is, however, somewhat different. The furnace example Spent a lot of air, because the fire needs oxygen to burn. These air he takes out of the room, even if the fire is extinguished. Even the warm chimney sucking air. Subsequently, a certain amount of ventilation. But this is still not as effective as in the above-mentioned high temperature difference. For if in the room even while several people are, this effect is not sufficient ventilation, and will be meaningless.

On the other hand, there are two systems for the ventilation of rooms: the respiration system and pulsing system, both in larger buildings, such as hospitals, applied.

Since the movement of the heated air in the rooms a permanent mixture of upper and lower atmospheric layers causes, it does not matter whether the openings used for the air near the ceiling or the floor holds. Because the proportion of carbon dioxide is everywhere evenly.
High-located openings lead but considerable quantities of heat (yet not used and warm) air. This would not be beneficial in the winter. The openings of pouring inside for the fresh, not preheated air, on the other hand, should not be so low. Because this is when the temperature difference leads then to the air movement and will be not comfortable.
