Dear all,
I am using daylight dependent control of artificial light in a hospital patient room and I would kindly ask you just to check if my procedure is correct.
Regulation requires to have:
- 300 lux at 0.90 m from floor for reading and examination at bed position
- 100 lux at 0.03 m from floor for general lighting
My aim is to regulate artificial light on the base of daylight by adopting a "continuous on/off" lighting control type.
In TRNBuild I defined two geoposition:
- geoposition 1: in the middle of the room, at 0.03 m from floor
- geoposition 2: bed position, at 0.90 m from floor
Then, I defined two gain types (added from the library):
- SIA_2024_Ltg_41classroom (to provide 300 lux)
- SIA_2024_Ltg_43library (to provide 100 lux)
and I selected "gain/loss related to reference floor area" for both gain types.
Afterwards, I defined two daylight control types:
- "GENERAL LIGHTING" for the gain "SIA_2024_Ltg_43library"
- "READING_EXAMINATION" for the gain "SIA_2024_Ltg_41classroom"
as reported in the pictures:

Is this procedure correct in order to ensure the illuminance levels required by regulations?
Thank you for your precious support and your time.
