Daylighting can have such a powerful effect on office workers’ comfort, well-being, and productivity, the buildings they occupy are now being oriented and designed to bring as much daylight as possible into occupied spaces. So say three experts on the topic, impaneled at the National Lighting Bureau’s Annual Lighting Forum. Moderated by EdisonReport Editor and Publisher Randy Reid, the panel comprised Sara Lappano, P.E., LC, LEED AP (SmithGroupJJR); Brent Protzman, Ph.D., LC (Lutron Electronics); and Seth Warren Rose (Eneref Institute).

Underscoring the impact of effective daylighting, Rose recounted a story about five libraries in Berkeley, California. The least-used library provided low-quality daylighting to the facility’s occupants. Once the building was renovated, with extensive focus on its daylighting characteristics, the library became Berkeley’s most popular.

Lappano noted that developing effective daylighting design is not simple. It requires a team approach involving the architect, lighting designer, electrical engineer, and – for purposes of energy-use modeling – the mechanical engineer. As Protzman noted, however, the team needs to develop a solution at the outset, and all team members need to focus on making it happen. In that respect, Lappano commented that team members must realize that more daylighting is not necessarily better daylighting, given that too much daylighting can have a negative impact on energy consumption and overall lighting quality.

As one outcome of the new emphasis on daylighting, Lappano said new buildings tend to be “slimmer” than their older counterparts, allowing almost all occupants to have a view out the window, giving almost all workers some of the benefit of a “corner office.” While this approach costs more to build on a per-square-foot basis, Protzman noted that those who intend to purchase or rent space find that the benefits of better daylighting justify higher prices for space acquisition.

sunny officeMy 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 of sleep, as well as the resulting quality of life, of office workers. The results suggest workers in windowed spaces tend to sleep better and longer than those without windows, while showing a greater tendency toward physical activity, possibly due to greater vitality.

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 February 25 and March 11 covering the building codes of New York State and New York City. The course will consist of three sessions: two 60–minute live webinars on Feb. 25 and Mar. 11 with a 90-minute selfguided session to be taken in between. Continuing Education credit is available for architects and engineers.

Study Concludes Workers in Windowless Offices Lose 46 Minutes of Sleep Each Night

daylightResearch 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 it begs the question of how well they isolated light as a factor as opposed to human factors such as income, job security, etc.

The study concludes: “We suggest that architectural design of office environments should place more emphasis on sufficient daylight exposure of the workers in order to promote office workers’ health and well-being.”

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 LightFlex daylighting system is available in 21” tubular as well as 2’ x 4’ and 4’ x 4’ configurations to fit a variety of fixture options for plenum ceiling applications. The larger unit options allow for fewer penetrations in the roof. The tubular device includes adjustable elbows to bypass interior ceiling obstructions in retrofit applications. The system comes standard with a conventional insulated square roof curb, which uses roofing industry-preferred flashing methods.
