[esp-r] Re: Blind control problem

[Jon Hand]

A question about blind control...

In the data below the likely cause is that the type of daylighting control
is "daylight coef".  This lighting control is expecting to access information
pre-calculated by the Radiance visual simulation tool.  It is likely that
the Radiance model of the building has not been correctly setup and
thus there is no lighting control applied.  Learning to use Radiance
well enough to generated the daylight coefficients is much more difficult
than the simpler lighting control types - sensing radiation.

The email did not include any information from the zone casual gains
control file which specifies sensor locations and logic associated with
dimming lighting in the zone so the user may only want to switch
the optical properties.

The 'surface for common location' is asking for the index of the surface
in the room.  For example, if you wanted several windows in a room
to switch based on solar radiation arriving at a surface named south_wall
and south_wall was the 4th surface in the room then you would supply
the index 4 to the control logic.

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.
