OFIS yearly conducts measurement campaigns of physical parameters (temperature, relative humidity, particles, etc.), chemical parameters (formaldehyde, benzene, etc.) and microbiological parameters (bacterial flora, fungal flora, etc.) at different points of air systems (air handling units, air outlets, offices ambient air).
A report containing the analytical results with graphs and comments, conclusions and recommendations for action is provided at the end of each audit.
The control at all levels of the air handling system allows us to precisely locate the observed degradation. Adjustments can be made for instance at the air handling unit, by optimizing the ratio fresh air / recycled air or by improving the efficiency of filtration and its maintenance. A servo-ventilation to a detection system of different air quality parameters can significantly solve common problems. For example, the monitoring of CO2 is used to detect air renewal issues. This is the principle of online monitoring associated with the automation that is promoted by OFIS.
