[esp-r] Blind control problem

[Chris Lee]

Dear all,

 

Recently I trying to apply internal blind control model for office building.

The problem is that illuminance control doesn't work and even solar
radiation, entering zone, doesn't change

However, solar irradiance and ambient temperature work quite well.

 

As I know, shaded pane will be active if illuminance, solar irradiance or
ambient temperature is greater than set point.

I gave set point of illuminance at 700lux for simple room and I found sky
illuminance is more than 10,000lux(sometime more than 20,000lux)

 

I will attach TMC contents (optical properties are library in esp-r)

Optical properties of blind in database are also conformed. 

 

I have made simple box model more than 10times to solve the problem,  but
the results are the same.

 

Also, what does 'Surface for common location' mean?

I can give option of 7, but I can't find what each number mean.

 

Please give me your advice.
