These graphs demonstrate how visual comfort improves by means of well-designed daylighting redirection elements. Calculating their size to shade the area close to the window reduces absolute lighting levels close to it (where they are quite strong).
The anidolic concentrator, planned to reflect incoming direct natural light, helped to increase lighting levels at the end of the room, while the lightshelf helped to reduce absolute differences
between front and bottom. This hour by hour analysis also confirms that device efficacy is reduced after a distance of around six to seven meters.
