Design and assessment of an anidolic light-duct

Lighting and energy performance of solar film coating in air-conditioned cellular offices

“…People expect good natural lighting in their working places [4]. New technologies such as photoelectric switching [5], laser cut penal [6], light shelf [7], light pipes [8][9][10], anidolic light-duct [11] and dynamic venetian blind [12] have been developed to enhance daylighting schemes. Daylight, however, is always accompanied by solar heat gain.…”

A daylight factor model under clear sky conditions for building: An experimental validation

“…The sum of these components is called the daylight factor (DF) (Acosta et al, 2013;Hopkinson et al, 1966). The analysis of DF depends on several characteristics of an atrium building: the sun orientation, the atrium shape, the atrium roof transmittance, the surfaces reflectivities of the atrium, and the penetration of daylight into the adjoining spaces (Canziani et al, 2004;Courret et al, 1998;Calcagni and Paroncini, 2004). The DF also depends on the orientation of the daylight aperture (with reference to the sun and the room orientation), any surrounding obstruction and the optical phenomenon (namely transmission, reflection and light scattering) occurs at the fenestration system through which daylight enters into the room.…”

Energy matrices of the building by incorporating daylight concept for composite climate—An experimental study

“…The more incidental daylight is received by top few floors while deep atria spaces are chiefly influenced by reflected and refracted light. [19][20][21] Previously, to enhance visual comfort, the laser cut penal, 19,20 light shelf, 21 light pipes, 22,23,25 anidolic light-duct 24 are innovative daylighting technologies to pass light from outdoor into the deep plan rooms to enhance daylighting schemes. In the present study, light well and clerestory window have been employed at SODHA BERS COMPLEX (SBC) to enhance occupant comfort (visual and thermal), physical health, and energy-efficiency.…”
