Deviation from due south should not exceed 15° in either direction for best solar access and ease of control. A maximum facade facing due south is the optimal orientation. from south to north has been shown to be viable for daylighting. A floor depth of no more than 60 ft., 0 in. If the project allows, consider a building footprint that maximizes south and north exposures, and minimizes east and west exposures. This is only possible for new construction projects and does not apply to retrofits. If possible, the building footprint should be optimized for daylighting. Since daylighting components are normally integrated with the original building design, it may not be possible to consider them for a retrofit project.

Beyond adding windows or skylights to a space, it involves carefully balancing heat gain and loss, glare control, and variations in daylight availability.
VISUAL LIGHTING 3 SAVE AS PDF HOW TO
The science of daylighting design is not just how to provide enough daylight to an occupied space, but how to do so without any undesirable side effects. This overview is intended to provide specific details for Federal agencies considering daylighting technologies as part of a new construction project or major renovation. Daylighting requires an integrated design approach to be successful, because it can involve decisions about the building form, siting, climate, building components (such as windows and skylights), lighting controls, and lighting design criteria. Implementing daylighting on a project goes beyond simply listing the components to be gathered and installed. Alternatively, suitable glare remediation devices such as blinds or shades must be made available. Further, the fenestration, or location of windows in a building, must be designed in such a way as to avoid the admittance of direct sun on task surfaces or into occupants' eyes. When there is adequate ambient lighting provided from daylight alone, this system has the capability to reduce electric lighting power. By providing a direct link to the dynamic and perpetually evolving patterns of outdoor illumination, daylighting helps create a visually stimulating and productive environment for building occupants, while reducing as much as one-third of total building energy costs.Ī daylighting system is comprised not just of daylight apertures, such as skylights and windows, but is coupled with a daylight-responsive lighting control system. Daylighting is the controlled admission of natural light, direct sunlight, and diffused-skylight into a building to reduce electric lighting and saving energy.
