The WELL Building standard was designed for "advancing health and well-being in buildings globally" [26] Part of the standard is the implementation of Credit 54: Circadian Lighting Design. Specific thresholds for different office areas are designated in order to achieve credits. Light is measured at 1.2 m above the finished floor for all areas.
A circadian clock, or circadian oscillator, also known as one’s internal alarm clock is a biochemical oscillator that cycles with a stable phase and is synchronized with solar time. Such a clock's in vivo period is necessarily almost exactly 24 hours (the earth's current solar day). In most living organisms, internally synchronized circadian ...
A circadian rhythm (/ s ər ˈ k eɪ d i ə n /), or circadian cycle, is a natural oscillation that repeats roughly every 24 hours.Circadian rhythms can refer to any process that originates within an organism (i.e., endogenous) and responds to the environment (is entrained by the environment).
The incidence of light on the human eye produces visual impressions, so its presence is indispensable for the capture of art. At the same time, light is intrinsically found in painting, since it is indispensable for the composition of the image: the play of light and shadow is the basis of drawing and, in its interaction with color, is the ...
Circadian rhythms have been documented for centuries. For example, French astronomer Jean-Jacques d’Ortous de Mairan noted the periodic 24-hour movement of Mimosa plant leaves as early as 1729. However, science has only recently begun to uncover the cellular mechanisms responsible for driving observed circadian rhythms.
The angle, lighting, and gaze of the Christ Child reproduces that of his mother, while John the Baptist reproduces these same elements in the face of Saint Anne. The lighting indicates that there are two protagonists, and two supporting cast in the scene that the viewer is witnessing. There is a subtle interplay between the gazes of the four ...
Charles Demuth, Aucassin and Nicolette, oil on canvas, 1921. Precisionism was a modernist art movement that emerged in the United States after World War I.Influenced by Cubism, Purism, and Futurism, Precisionist artists reduced subjects to their essential geometric shapes, eliminated detail, and often used planes of light to create a sense of crisp focus and suggest the sleekness and sheen of ...
The visual system is the physiological basis of visual perception (the ability to detect and process light).The system detects, transduces and interprets information concerning light within the visible range to construct an image and build a mental model of the surrounding environment.
