LAB.1 realized daylight calculations in three stages. Firstly, we carried out external illumination calculations for representative dates (four different times of day, and one day for each month). Secondly, detailed calculations were carried out for the sunniest month, July, with a detailed analysis of all the exhibits, particularly regarding specifying projectors. At this stage, we prepared 3d models and performed daylight calculations for all eight floors separately. Lastly, we made annual daylight calculations for all floors, without the exhibits.
