Daylight factor prediction in atria building designs

Solar Energy, 2004
This paper investigates the main characteristics of the atrium and their influence on the daylight conditions in the adjoining space and on the atrium floor. The shape of the atrium and its orientation to the sun, the transmittance of the roof, the reflectivities of the atrium surfaces and the glazed areas are important parameters in the daylighting ...

Portable photoelectric daylight factor meter

Journal of Scientific Instruments, 1936
The practical conditions controlling the accuracy of measurement of daylight factor are considered in the first section of the paper. A simple portable photoelectric daylight factor meter, incorporating two rectifier photoelectric cells, is described. The direct range of daylight factor measurable by the meter is from 0.03 per cent to 2.5 per cent. The

A Daylight Factor for Clear Sky Conditions

Architectural Science Review, 1999
This paper describes a method for estimating the daylight factor under clear sky conditions. The internal illuminance is divided into two components; light received directly form the window, as a diffuse source, and light reflected from the internal surfaces of the room.
