Modeling Retractable Roof

[AYDASAHAF]

Hi

I want to model a retractable roof, which is a roof of a stadium. I modeled the retractable part as window.

In order to model the retractable roof, I do not want to use Macroflow. Since I am modeling the infiltration in the relative zone in the thermal templates. I am using formula profile and max value for infiltration received from CFD analysis. hence the infiltration is already being taken into account in the formula profile I created in the thermal template section. By opening the roof via Macroflow, I would model additional infiltration which is not wanted.

Hence I am looking into other ways like having external shades being modeled for the retractable part, and give it a schedule as wanted, to model retractable roof? I never worked with defining external shades in the construction tab for the glazing system. Can you advise which type is the best for this case, and for the values that needs to be defined how I can fill them out like incident radiation to lower,....

Thanks
Ayda
