Il contesto
Parcheggio Laurentina. Roma, 2026.
Infrastruttura ATAC nel quadrante sud di Roma. ~15.000 passaggi/giorno tra auto e pendolari della metro B. Qualità aria critica per traffico e ventilazione limitata.
Dati location
- Tipologia
- Parcheggio sotterraneo multipiano
- Gestore
- ATAC S.p.A.
- Città
- Roma — Zona Laurentina
- Traffico medio
- ~15.000 passaggi/giorno
- Superficie
- ~8.000 m²
Problema rilevato
Le misurazioni baseline hanno evidenziato concentrazioni di PM2.5 significativamente superiori ai valori guida OMS (5 μg/m³), con picchi nelle ore di maggior traffico veicolare in entrata/uscita.
In assenza di purificazione attiva, ogni utente del parcheggio era esposto a livelli di particolato potenzialmente dannosi per la salute respiratoria, specialmente per anziani e bambini.
Methodology
How we measured it.
Every figure is verifiable. Here is the complete procedure.
01
Baseline sensor setup
Before installation: PM2.5 and PM10 readings for 7 days. Baseline data certified by independent laboratory.
02
E-Bufaga 2.0 activation
Installation in 4 hours. IoT system connected and operational within the same day.
03
30-day continuous monitoring
Internal and external device sensors sampling every 60 seconds. Real-time cloud data.
04
Results certification
Statistical analysis of pre/post deltas. Certified report signed by a third party. Public, downloadable.
Voci istituzionali
Cosa dicono i partner.
“Un progetto che dimostra come pubblico e privato possano collaborare concretamente per migliorare la qualità della vita in città.”
“I dati raccolti durante il pilota ci danno una base solida per valutare l’espansione del modello su altri hub della rete ATAC.”
Scalability
From pilot to network.
Immediate replicability
The same model applies to any infrastructure with >300 passages/day: metro, car parks, shopping centres, airports.
Self-financing via advertising
The integrated digital screen generates advertising revenue that covers operating costs. The PA pays nothing.
Data as an asset
Every installation produces a unique air quality dataset. Value for PA (policy), research (academic) and brands (ESG accountability).
Frequently asked questions about the ATAC pilot
What is the Bufaga-ATAC pilot at Rome's Laurentina metro station?
It is the first public-private air purification pilot in an ATAC infrastructure: an E-Bufaga 2.0 device installed in the multi-storey underground car park at Laurentina (~15,000 passages/day, ~8,000 m²), with continuous PM2.5 and PM10 monitoring.
What results did the pilot produce in 30 days?
In 30 days of operation the device generated over 430,000 clean breaths, with uptime above 95% and zero unplanned downtime, continuously removing PM2.5 with data verified by third-party-certified IoT sensors.
What does the pilot cost the public administration?
The cost for the public administration hosting the installation is zero: the project is funded through a revenue-share model on the advertising of the Green DOOH display integrated into the device.
How was the pilot's data measured and verified?
Before installation, 7 days of baseline PM2.5 and PM10 data were recorded, certified by an independent laboratory. After activation (installed in 4 hours), sensors inside and outside the device sampled the air every 60 seconds for 30 days, with data sent to the cloud in real time.
