It is a well-known fact, however, at KE Fibertec we were
recently reminded of how important it is to have a healthy indoor
climate in order to maintain high productivity and a good working
During week 12 the floor of a large common room had to be sanded
and recoated. To avoid dust in the ventilation system it was turned
off Monday and Tuesday. That gave us the opportunity to measure the
conditions with and without mechanical ventilation including our
based ventilation system for air distribution, and the
difference was quite astonishing.
Using our InTex
Meter we are able to measure e.g. temperature and
CO2 level. These factors present us with an overall
picture of the indoor climate of the room.
The room temperature climbed to 24.7°C during Tuesday (at
an outdoor temperature of 10°C).
Normally, the CO2 level is below 500 PPM in
this administrative room, but with no ventilation running it rose
to critical 1332 PPM during Monday. If the CO2 level
exceeds 1000 PPM it may result in headaches and fatigue late in the
day which is a very unfortunate development.
Under normal conditions with the textile based ventilation system
running, the indoor air quality of the room is on a par with the
outdoor air quality - approx. 450 PPM. The ventilation system was
turned on again on Wednesday, March 23 at 10 a.m. It takes about 13
hours without ventilation and heat load of persons before the room
is back at around 500 PPM.
Above "mini analysis" of the impact with and without ventilation
speaks volumes. Mechanical ventilation is necessary to maintain a
healthy indoor climate and by that high productivity level at the
You, too, can measure the indoor air quality at your workplace by
using the InTex
Meter by KE Fibertec. Contact us for further information.
