Case studies :
Predictive HVAC control of a primary school


  • Primary school
  • 520m2 – one level
  • North of France
  • 16 room

Ventilation system

  • Double flow AHU
  • Two operating speeds :
    100% or 22% of its capacity

Heating system

  • Heat pump
    Atlantic Excellia 18kW


Managing the school’s HVAC system, making the right compromise between indoor air quality and outdoor air quality.

Save energy without damaging indoor air quality

QAI école

Deployment of INDALO® Supervision
Smart plan

indoor air quality

Installation of 4 sensors on the premises:
– 2 CO2 – light VOC sensors
– 2 CO2 – PM – total VOC sensors

Online control of
the dual-flow AHU

The VMC is controlled by limit values for the concentration of CO2 and particulate matters.

Expert plan
Predictive HVAC 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.
