[EnergyPlus_Support] Light shelf simulation in Energy Plus

["Belal" <bka255@xxxxxxxxxxx>]

Hi all,

I'm a new user to Energy Plus, i want to add an exterior light shelf to an existing model.(The model already includes an exterior overhang).

I tried to increase the reflectivity of the overhang top side from 0.5 to 0.9, but it made no difference. Then i created a new material and a new construction for the light shelf material, and added a light shelf in the daylighting category and defined the top side of the overhang as a light shelf, but i get empty spreadsheets for the results.

Is there something wrong i did? Please help me resolve this issue so i can move on with my mater's thesis.

Thank you all,

Belal
