My experience is with BEopt running EnergyPlus where BEopt assumes the following:

1. Blinds are always present - i.e. not a user variable
2. Blind use is scheduled and either up or down (0 or 1 schedule)
3. When down, solar gains are multiplied by a constant interior shading multiplier of 0.7 (or reduced by 30%)

See the WindowProperty:ShadingControl object in the EnergyPlus Input Output Reference or do a quick sim in BEopt and then look at the IDF for the assumed schedule.
