Radiance and blinds

I had an Openstudio model without shading. Then I added interior blinds and ran simulation using EnergyPlus and Radiance. The results were strange (electricity use for interior lights was smaller with blinds (even with slat reflectance 0)). Then I started looking for a glitch, and found out that the electricity use for interior lights is not the same when I simulate a model without a shading and a model with shading always off (which should be he same, right?).

Any sugestion why electricity usage is not the same in both cases?
