What it does

FLO2 FAIR+ connects to any existing HVAC system, whether AHU, VRF, inline fans or split units, and shifts it from fixed-schedule operation to demand-based control. Ventilation responds to actual occupancy and air quality conditions in real time, reducing energy consumption while maintaining indoor air quality within required thresholds.

How it works

Step 1

Sense

CO₂ sensors and occupancy inputs provide a continuous picture of conditions in each served zone. When occupancy increases above threshold, the zone requires more fresh air. When occupancy drops, it requires less.

Step 2

Decide

Control logic processes sensor inputs against configurable parameters including CO₂ setpoints, occupancy schedules and outdoor conditions, and determines the appropriate response for each moment.

Step 3

Act

Fresh air intake adjusts. Where outdoor conditions permit, ambient air is used to reduce mechanical cooling load. AC units are managed to maintain comfort without unnecessary compressor hours.

Step 4

Record

Every reading and every control action is timestamped and cloud-logged. Historical data is structured for compliance export without manual data assembly.

What it delivers

HVAC energy reduction of 20 to 60 percent across installed sites
CO₂ maintained below 800 ppm in occupied zones
Compliance-ready data for IGBC, LEED, WELL, GRIHA and RESET
Continuous cloud dashboard with real-time performance visibility

Energy performance by climate zone

Observed reductions across FLO2 FAIR+ deployments in Indian cities.

Location	Observed Energy Reduction	Primary Driver
Chennai	12 to 18%	Humidity management, reduced over-ventilation
Bangalore	15 to 25%	Free cooling potential, low active cooling demand
Hyderabad	30 to 40%	Replacement of constant fresh-air systems with adaptive control
