For a Natural Ventilation System to be Effective there must be:
-
An Efficient means of extracting warm and stale air through roof mounted ventilators.
-
Adequate low level provision for the entry of fresh air at ambient temperature.
- The ventilators must be of a high standard to ensure they are at optimum performance.
 |
GOOD VENTILATION |
| Efficient turbine ventilators exhaust hot and stale air and provide a given number of air changes per hour for the building. |
 |
NO VENTILATION |
| Absence of roof ventilators prevents hot and stale air escaping the building. |
