Case study :
Air handling unit control for a nursery


  • Nursery
  • 900m2 – one floor
  • North of France
  • 15 rooms

Ventilation system

  • Double flox AHU
  • CAD O Integral EI 45 VLEXG
  • Operating speed adjustable between 0% and 100% of capacity

Heating system

  • Gas boiler
  • Atlantic Guillot LRP4 145kW


Controling the nursery’s AHU by making the right compromise between indoor air quality and outdoor air quality.

Save energy without compromising IAQ

Deployment of INDALO® Supervision
Smart Plan

indoor air quality

Installation of 4 sensors in the nursery :
– 4 CO2 – PM – total VOC sensors

Online control of
the dual-flow AHU

The AHU is controlled by limit values for the concentration of CO2 and particulates matter (PM2.5)

Results with predictive
ventilation control only

- 0 %

Expert Plan
HVAC predictive control

Predictive control of heating according to occupancy, external disturbances (weather) and the building’s thermal inertia.
In this way, we limit situations of over-consumption and discomfort.
