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.
The Actual Age is the number of years that have passed since the structure was built. Actual age is also called the Chronological Age. The Effective Age is the estimate of the age of a structure based on its utility and physical wear and tear. The effective age is the difference between the Economic Life of the structure and the Remaining Economic Life of the structure. The appraiser considers effective age in any appraisal.
