Hello,

I did APpache Sim sensors and I made dimming profile. After APSim the electricity consumption had 90% reduction that is not logical. In addition,why I can not see solar gain and sensor values in the vista results?

Is there other way to calculate effect of glazing on lighting consumption except APSim sensors , because it is too time consuming.
Thanks.

You can predict the Dimming profile on the rooms and not actually reference any calculated variables but the link to Radiance sensors is the only way for the software to predict lighting control based on the actual geometry in your model.

If the simulation was run with the Radiance link ticked in simulation settings then when you select any room in Vista you should be able to select the room level variable "Daylight illuminance 1" and see the illuminance value used in the simulation for that room (it's based on the sensor result from Radiance but I think Apache may apply a function to it in some cases so may not exactly match).

Daylight illuminance 1 is the variable e1 we reference in profiles.

Thanks a lot.
