IAQ simulation · design phase

The air quality of your buildings, anticipated.

i4o simulates the pollutant concentrations of your future buildings from the design stage — with no physical measurement, and results ready to use for your HQE, BREEAM and LEED certifications.

What i4o does

Models without measuring.

Predicts indoor pollutant concentrations (CO₂, TVOC, HCHO, PM2.5, PM10, NO₂, O₃, humidity) from the model, the materials, the outdoor environment and the ventilation.

Checks compliance.

Automatically checks your results against the HQE Bâtiment Durable, BREEAM and LEED frameworks — with a certifiable report export.

Anticipates non-compliance.

Identify and correct deviations before building handover, not after.

Who it's for

One tool, two challenges.

For engineering firms

IAQ simulation at the design stage is now expected in the major environmental certifications. i4o lets you offer this service, bring it in-house and highlight it in your tender responses.

For building owners

Anticipating indoor air quality means avoiding costly non-compliance at handover. i4o produces certifiable deliverables, ready to be used directly by your certification body.
