Direct light (from the direct sunlight at the desired location on the floor or other surface); Once a design is executed, ensure operational success by educating building occupants and operators on the intent of the daylighting design, how to use lighting controls, and how to access and use shading controls. The human desire for change wrought by the changes … It is the “seasonal variability of interior daylight illumination,” Heschong says, “along with views to the outdoors that provides important stimulus to the circadian system, [and] along with making any space more pleasurable and interesting for its occupants.”. Do office workers with exposure to daylight experience better general health? We wrote an article on whether or not wellness architecture was the future of the industry, and it’s certainly true that natural light is a significant part of this. As the sun makes its daily transit from east to west, shadows convey sense of time. Zenith light (from the ceiling like a skylight); Light is critical to human functioning in that it allows us to see things and perform activities. Today, computer-based simulations are becoming increasingly popular, especially when daylighting and energy conservation are amongst the key goals for a project.

Kevin Van Den Wymelenberg is a professor at the University of Oregon, where he directs the Energy Studies in Buildings Laboratory, co-directs the Biology and the Built Environment Center, and directs the Institute for Health in the Built Environment. Integrating Daylight with Design While daylight is a variable, often unpredictable, light source with a spectrum that depends on solar position and sky conditions, it is also rich in the short-wavelength portion of the visible spectrum found to support both alertness and circadian sleep–wake entrainment. In 1862, Henry David Thoreau wrote, “In Wildness is the preservation of the world.” If he were to see our modern cities, our buildings, and what remains of the wild, perhaps his reaction would be similar to what David Orr, the Paul Sears distinguished professor of environmental studies and politics at Oberlin College, noted in his book Design on the Edge: The Making of a High-Performance Building (The MIT Press, 2006): “Modern designers filled the world with buildings and developments divorced from their context, existing as if in some alien realm disconnected from ecology … and place.” In cities today, daylight might be the last trace of Thoreau’s idea—and might be, in fact, the preservation of wildness. There are examples in contemporary architecture that have used light in a masterly way. Light, natural paint colors, such as green, blue, and yellow, will brighten spaces and help light reflect throughout the space. It seems like design is moving towards natural light and finding ways for it to permeate further into the interior of buildings. … Daylight and the Circadian Cycle The biological processes that regulate our sleep–wake cycle make up our circadian system. In the practice of architecture, daylighting refers to the use of natural light, be it brilliant sunlight or muted overcast light, to support the visual demands of building occupants. Since photopic vision is critical to visual tasks, most electric light sources are designed to support it. The 1999 study “Skylighting and Retail Sales: An Investigation Into the Relationship Between Daylighting and Human Performance” and the 2002 study “Daylighting Impacts on Retail Sales Performance,” both by HMG, are arguably two of the most robust investigations into daylight and its effects on retail sales to date.

Those fortunate enough to have windows might keep the blinds open, especially if the view is nice, and let in some natural light. If Thoreau’s belief about “Wildness” is true, then we should take the opportunity to introduce the wildness of daylight into our structures. Yet, it is the factor that decision-makers most often value when choosing whether to include daylight and advanced controls for lighting and blinds. The defining aspects of green building are sustainability, and a low environmental impact. A belief that daylighting is beneficial does exist, but hard evidence is still scarce. “Productivity is incredibly difficult to quantify in terms of time and money,” Park says. #mc_embed_signup{clear:left; font:14px Helvetica,Arial,sans-serif; width:260px;} Architect Magazine: Architectural Design | Architecture Online:  The premier site for architecture industry news & building resources for architects and architecture industry professionals.
