Re: [EnergyPlus_Support] direct solar irradiance in the workplace as control system indicator - EMS

["Jean Marais jeannieboef@xxxxxxxxx [EnergyPlus_Support]" <EnergyPlus_Support@xxxxxxxxxxxxxxx>]

You put a sensor to monitor an output variable, but you add an actuator to change an available component. The easiest components to actuate are schedules, so your logic can change what the usual value of your blind deployment schedule is.

Hi all, I hope that you can help me with this:  I'm using EMS to simulate the control of exterior venetian blinds. I need to set a control to deploy the system when direct solar irradiance of above 50 W/m2  hits the work place. I cannot find an ouptut varialble in the .rdd file that could be used for that.

I found:

Output:Variable,*,Surface Window Transmitted Solar Radiation Rate,hourly; !- Zone Average [W]

but how to define the surface of the workplane as a trigger indicator

or

Output:Variable,*,Surface Inside Face Interior Windows Incident Beam Solar Radiation Rate per Area,hourly; !- Zone Average [W/m2]

or 

Output:Variable,*,Surface Inside Face System Radiation Heat Gain Rate per Area,hourly; !- Zone Average [W/m2]

(is not clear to what 'surface' it refers, and in any case is not exactly what I need).

Can anybody help me to figure it out a way of doing this?

I'd appreciate your help, thank you

Steph
