Daylighting

As part of current research sponsored by Southern California Edison, the California Lighting Technology Center (CLTC) is updating its Advanced Daylighting Lab to include dynamic fenestration and integration of electric lighting and HVAC systems. Activities are being conducted in collaboration with ready-to-integrate manufacturing partners so that new systems can more quickly and effectively transition to [...]

ARCHITECTURAL LIGHTING recently published an article about annual daylighting performance metrics–Spatial Daylight Autonomy and Annual Sunlight Exposure–adopted by the IES. These metrics enable designers to quantify and evaluate the success of daylighted spaces. Check it out here.

My lighting column in the March issue of ELECTRICAL CONTRACTOR covers a new University of Illinois study that attempted to link daylight exposure to quality and duration of sleep among office workers: “Recently, a multidisciplinary team at the University of Illinois, Urbana-­Champaign, set out to determine the effect of daylight on the quality and duration [...]

The Cooper Union for the Advancement of Science and Art and the Illuminating Engineering Society are offering a new series of online courses, DAYLIGHTING & CODES, designed to explore the benefits of daylighting in the energy codes of various states and cities. The first of the series will be a 5-hour course taking place between [...]

Research by an interdisciplinary team at the University of Illinois found that office workers in windowed spaces scored better on common self-report health and sleep surveys, averaging 46 minutes of sleep per night (measured by sleep monitor) compared to workers without windows. More evidence that appropriately designed lighting may be preventive medicine? Maybe so, though [...]

Everybody loves daylight. Get the story here.

The Illuminating Engineering Society (IES) recently published Recommended Practice for Daylighting Buildings (RP-5-13). This Recommended Practice module includes the most up-to-date data on the many benefits of daylighting, including energy savings of 40-50% or more. It also offers information and expertise on daylight delivery methods, glazing systems, shading techniques, control strategies and daylight performance simulation [...]

Sunoptics’ LightFlex system is a high performance prismatic daylighting solution for suspended-ceiling applications. The LightFlex toplighting system uses the Sunoptics Signature Series prismatic skylight, which allows the system to efficiently capture low-angle sunlight and optimize light distribution. A patent-pending optic sphere drives light down through the skylight’s light well, maximizing the system’s light penetration. The [...]
