Got Light Scoops? New Design Guide for the Latest in Daylighting
The Lighting Research Center (LRC) at Rensselaer Polytechnic Institute recently released a design guide for light scoops—skylights that provide more strategic light through daily and seasonal fluctuations than conventional skylights do.
Particularly effective in cloudy and overcast climates, light scoops face south and are angled at either 45 or 60 degrees in order to receive light from the zenith (the brightest part of the sky) during the winter, and more indirect light during the summer. According to the guide, in a recent project where 14 light scoops were installed at the Welch Allyn corporate headquarters in Skaneateles, New York, almost 90% of occupants were highly satisfied with the results.
Light Scoops: A Design Guide—available as a(PDF) on the LRC website—offers guidance on determining the angle, glazing area, dimensions, glass specifications, and color finishes to meet target light levels. Modeling software can be used to compare different features, but the guide cautions that simulations should take into account a variety of weather conditions.
The resource simplifies light scoop design as evidence builds for daylighting’sand benefits.
