2. 1.Considering direct sunlight within buildings 2.Direct sunlight – a multidimensional phenomenon 3.Related work 4.SPOT- Time Projection - Navigable animation - Demo 5.Implementation 6.Future work

3. 1- Why to consider direct sunlight in buildings ? Benefits of the sun : ENERGY SAVING: >Artificial lighting = 25 % of the electric energy >"efficient daylight = energy saving (by 30-60% )“ PRODUCTIVITY: >Students : learn faster, test higher. sales increase an average of 40% HEALTH: Alleviates: stress, anxiety, depression, migraines, sleep disorders, immune system function, cholesterol levels, increases calcium utilization, visual acuity, Cardiac outputs.
