These are the values expected in a room not yet occupied: CO₂ close to outdoor air, temperature and humidity in the comfort zone. From here on CO₂ rises, because every breath leaves it in the air.
The actual measurement of the room runs all day. We publish it at the end of the event.
It is a measurement.
What you are reading is not a value prepared for the occasion: it is the same data that reaches the spaces we monitor every day, produced by the same process.
Continuous
Not a two-day campaign once a year. A value every few minutes, without interruption.
Explained
A number on its own is no use. The system explains in plain language what happened and why it matters.
Certified
Every measurement is written to an immutable public register as soon as it is taken. No one, including us, can change it afterwards.
Cosa si fa.
Most of the actions that improve indoor air cost nothing. They are invisible only because no one knows when they are needed.
Measuring is not about building new systems. It is about knowing what to do, and when.
- Open up. A window, a door. Now, not tomorrow.
- Change a schedule. Move air exchange to the time when it is really needed.
- Reduce crowding. At the hour when the curve always rises.
- Check the system. Does the declared air exchange match the real one?
Wherever people spend many hours indoors.
Schools, workplaces, gyms, hotels, restaurants, museums, coworking spaces. Oxia® provides the continuous, certified measurement infrastructure on which a qualified technician builds the assessment under the Italian standard UNI 11976:2025.
