Term descriptions

LIGHT CLIMATE is referred to as a variety of conditions of natural lighting in a certain area for the period of more than 10 years.

See appendix p117 «Types of insolation regimen».

NATURAL LIGHTING is referred to as direct or indirect (reflected) light which penetrates through window openings and/or doors in the outer boundary structures.

INSOLATION is referred to as penetration of direct solar rays through window and door openings.

COMBINED LIGHTING is a combination of natural and artificial lighting.

Coefficient of natural lighting is the ratio of natural lighting at a certain point within a building/room produced by direct or indirect light to the simultaneous value of external horizontal lighting produced by the light coming from a completely cloudless sky (it is calculated in %).

LOCAL LIGHTING is the lighting supplementary to general lighting produced by lamps whose light flux is directed immediately towards workplaces.

GENERAL LIGHTING is the lighting produced by the lamps regularly spaced in the upper part of the room or directed towards the equipment.

LIGHT CLIMATE - a total of all the natural lighting conditions in a certain area over the period of 10 years.

LIGHT FACTORis the ratio of the glass area of windows to the area of the floor.

COMBINED LIGHTINGis the lighting when insufficient daylight is complemented with artificial lighting.

ANGLE OF INCIDENCE is the angle at which a light ray strikes a horizontal area in a room (e.g. desk, etc.); it is formed by two lines, a horizontal and a vertical one. The former is drawn from a certain point (the surface of the desk) to the lower edge of the window; the latter is drawn from a certain point to the upper edge of the window.

APERTURE ANGLE is the angle which determines the area of the sky which immediately illuminates the working surface. It is formed by two lines, upper and lower. The former is drawn from a certain point to the upper edge of the window, the latter is drawn to the highest point of the opposite building or tree.

STABILITY OF DISTINCT VISION is the ability of the eye to discern small pieces over a period of time.

total study time ____ sec., total of all time spans when a piece was quite clearly seen ___sec.

CD (Coefficient of depth) is the ratio of the height of the window to the distance between the window and the opposite wall. It should be no more than 1: 2, 5.
