- Light technology calculations
All light technology calculations can be performed with the aid of additional graphical instruments (see example pictures). By varying specific individual steps, the instruments (unlike other computer programs, which require a considerable amount of input) are extremely suitable for the advance testing and accurate assessment of special geometrical solutions.


Hanns Freymuth used this procedure for many different kinds of building projects (museums, hospitals, university buildings, schools, sports facilities, residential and administrative buildings, industrial buildings, churches etc.) during his decades of consultancy work up to 1997 and extended it, one particular addition being a full “Set of solar heat diagrams” with which the insolation for surfaces with any orientation or incline can be determined during the course of a year in a simple way.
