How It Works
About AQDV
AQDV (Air Quality-Driven Ventilation) is ARM Environments’ advanced control strategy that goes beyond time schedules and CO₂ thresholds to deliver smarter, healthier, and more efficient ventilation.
Most buildings ventilate according to fixed occupancy schedules – whether the space is busy or empty. Some improve on this by responding to CO₂ levels. But AQDV takes a step further: it ventilates only when doing so will actually improve indoor air quality.
Using real-time data from indoor and outdoor environmental sensors, we build a digital twin of your building’s ventilation system. This twin continuously compares pollutant levels inside with those outside and calculates the optimal ventilation rate based on actual air quality – not assumptions or arbitrary thresholds.
The result is a dynamic system that avoids bringing in polluted outdoor air unnecessarily, reduces energy use, and maintains healthier conditions even in buildings affected by traffic pollution, poor filtration, or inconsistent occupancy.

AQDV FAQs
Is AQDV suitable for existing HVAC systems? ↓
AQDV is a low cost quick impact solution which can be integrated into existing buildings seamlessly.
What data is used? ↓
Sensors for real-time monitoring of IAQ and OAQ parameters (CO2, PM, VOCs, temperature, humidity).
Will I need different filters? ↓
Possibly. Building modelling provides accurate filter selection based on AQDV principles.
Is this solution compliant with building regulations? ↓
Yes. We conceived the solution in response to Approved Document F 2.6 and constructed it using existing technologies.
Is filter waste really such a big problem? ↓
83,685 Tonnes of air filter waste will be sent to landfill or incinerated by 2028.
