How
Much Ventilation?
The adequate ventilation of an indoor space is essential to maintain
health and comfort. European CEN Standards now define air quality
and specify ventilation ranges that are needed to achieve these Standards.
High air quality requires ventilation in the range of 15 - 25 L/s for each
occupant present in a space.
Poor air quality has been shown to:
- Spread illness and disease;
- Reduce productivity;
- Create discomfort.
Substantial research dating back over 100 years has shown that
ventilation rates at less than 8 L/s per person are inadequate. The CEN
values largely confirm this. UK Building Regulations (Part F 2006) now
require a minimum ventilation rate for office premises of 10 L/s per
person. |
