Daylight calculation was realised 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 sunniest month, July, with detailed analysis of all the exhibits, particularly in regard to specifying projectors. At this stage, all the ﬂoors were modelled separately and eight different models were produced and calculated.
Lastly, annual daylight calculations were made for all ﬂoors, without the exhibits.
