Département Développement DurableDépartement Développement DurableAimsAims
Development of smart systems to integrate the control of lighting, blinds and HVAC applications to :
=> improve the indoor environement(thermal confort, visual comfort, indoor air quality)
=> reduce energy consumption

A good integration can be achieved througha limited data exchange
Define the data to be exchanged betweencontrollers

Département Développement DurableDépartement Développement DurableAimsAims atat the zone the zone levellevel
At the zone level the different applications shall enable to reach the following goals:
Provide requested thermal comfort
Provide requested illuminance level
Avoid glare or provide requested contrast level
To reach these three different goals three different actuators can be used at the zone level:
Heating/cooling actuator
Artificial lighting
Solar protection.

Département Développement DurableDépartement Développement DurableIntegrationIntegration of light of light andand blindblind
1st strategy:
There is no integration but optimised glare controller
2nd strategy:
There is a first level of integration. The illuminancecontroller sends requests to the glare controller.
3rd strategy:
2nd level of integration. The illuminance controllersends requests to the glare controller and the latersends back it's possibility to move up.

Integration of simple algorithm leads to a large improvement
Integration of already optimised stand alonealgorithms does not lead to significantimprovement
Question?What is the best approach

Département Développement DurableDépartement Développement DurableConclusionConclusion
data to be exchanged are defined
process to implement strategy involving differentmanufacturers was tested
prototypes are implemented in a demonstrationroom
connection to service and plant level have been defined but not implemented in demonstrationroom
the structure is ready, better algorithms can bedefined independantly by the manufacturers
