BSD has developed several software calculating modules for specific purposes of calculating daylight and energy transmission in double skin facades and retro-optical shading systems. 

•Special algorithms and programs for façade solar energy and daylight calculations;

•Programs for economical calculations of the effects from the applied façade concept.

Specialized database with properties for different glass and blinds combinations;

Energy calculations of different blinds models, shapes etc.;

Energy calculations for different glass combinations and shading devices;

Specialized ray-trace and energy distribution analyzes.

Energy simulations for different glazed and shading concepts without or with combination with BMS.
