Solar radiation is poor, as you can see on the radiation Typical fm oorplan 1:200 map images, so in such a case energy consumption would dramatically increase. Ti e rest of the daylight factor calculations are on the chosen design South facade fully tilted. Glare and illuminance interior calculation (reduced tilt). Ti ey show the daylight situation in a room at the exterior MEAN DAYLIGHT FACTOR 4.65 % facades, as well as at the part facing the inner core. MEAN DAYLIGHT FACTOR 2.58 % Note: Ti e daylight factor can vary depending on the rotating position of the lamellas. It is calculated for the south facade and it ranges from 1.35 to 2.32 percent. Plan Layout: Each fm oor provides plenty of private and more open work spaces, conference rooms and dining areas. Ti e central core brings light down to the lowest fm oor and North facade East facade spreads it inside. Installations rooms and communications are situated around the core for convenience.
