Poor indoor air quality leads to the emergence of symptoms ranging from headaches to allergies and asthma.

Whether as part of a sustainable approach (environmental certifications), complaints from occupants or a simple IAQ assessment at the reception of a building or during its operation, IAQ measurements are an asset in deciding on the state of indoor air.

Benefit from the assistance of OXIVI, your thermal and indoor air quality (IAQ) design office.

With its partner laboratories, OXIVI has a dual expertise in building and indoor air quality in the communes of Amiens, Lille, Arras and the surrounding area. The measurements carried out by the OXIVI team are analysed as part of a strict quality approach before the report is issued, including its recommendations for improving the IAQ of the building concerned:

  • CO2
  • Formaldehyde
  • Benzene
  • Mould
  • Nitrogen Dioxide (NO2)
  • Hygrometry
  • Total VOCs
  • Fine particles
  • Lead dust

The air permeability test

The blower door test, or air permeability test, is used to identify air intakes that affect the thermal and acoustic comfort of a building.

It represents an essential point in improving the energy efficiency of a property.

The RT 2012 thermal study (Bbio certificate, end of works certificate, etc.), the new energy assessment (DPE) and the blower door test include :

  • Fillings, caulking and installation of the blower door
  • Depressurisation of the building (NF EN 13829)
  • Searching for parasitic air infiltrations
  • Submission of an air permeability report including the Q4pa-surf values according to RT 2012 and n50 according to NF EN 13829 and application guide P50-784.
