Hi all,

I am concerned over the different outputs associated with defining internal blinds in E+ (i.e. defining the blinds as constructions with shading or as standalone devices in the WindowProperty:ShadingControl object).

I want to upload the two files but there is insufficient space (any ideas?). They are exactly the same except for how the blinds are defined (construction layer or standalone).

I have 9 zones of key interest to me in this building as these are the zones that use advanced lighting controls and blind control (south facing in a desert environment). I employed â??Zone/Sys Sensible Cooling Energyâ?? to check if they are identical. However, the output suggests this is not always the case. In my simulation runs, the values for one of these zones (C_S_W:Zone/Sys Sensible Cooling Energy [J](Hourly)) differs by 1.5%. This may seem small however should the output not be exactly the same?

I would appreciate your input.

Many thanks

-Elmer
