Outside
Outdoor sensors measure particles, NO₂ and wind around the building. Until they are installed, the nearest state station is the reference.
Pilot project · N99 Tech Park, Skopje
Live since November 2026Terra Regina 360°
The first pilot.
Terra Regina and N99 Technologies are making N99 Tech Park the first site where city air, indoor rooms and purification work as one system. It is measured live, shown on screen and, step by step, acted on automatically.
×Terra ReginaThe partnership
One building.
The whole loop.
N99 Tech Park in Aerodrom, Skopje, is home to labs, offices and a showroom. Together with N99 Technologies we use it as a living test site. Outdoor air, indoor monitors, purifiers and screens all run on one Terra Regina platform.
What we learn here becomes the standard setup for offices, schools and public buildings.
Running today
- 4 indoor monitors in the laboratories, showroom and office
- Live TV display on site, with Macedonian voice alerts
- Public QR page with current values for visitors
- Outdoor comparison with the nearest state monitoring station
- Panel access for the N99 team, with history and charts
Live
N99, right now.
Current values from the rooms, refreshed every minute. These are the same numbers the TV on site shows.

Outside awareness.
Inside action.
Inside
Each room has its own monitor for CO₂, PM2.5, VOC or formaldehyde, noise, temperature and humidity.
Respond
When indoor air gets worse, a smart switch starts the purifier. The TV and voice alerts tell people when to open a window.
Show
The panel, the TV in the room and the public QR page show the result, so everyone sees the air getting cleaner.
The hardware
Real devices.
One data layer.
Indoor monitors are running. The outdoor devices and purifier automation are the next phase of the pilot.
