âThe savings are roughly 9 percent for the corridor and 17 percent for the classroom,â the study found. With this same scenario, switching from a 30 percent to a 45 percent light reflectance floor results in an energy saving of roughly 4 percent for corridors and 9 percent for classrooms.
The Axial Age is defined by Jaspers as occurring in the interval from about 800 to 200, but a closer analysis suggests the need to modify and break up this interval. However, the basic point is clear. But the Axial phenomenon is evanescent and begins to wane rapidly by 400.
