The IES San Francisco and the Pacific Energy Center will present a Daylighting Spring Education Seminar: A Complete Picture of Daylight. This course will include a 2 hour presentation with in-class exercises on daylighting metrics, followed by a 30-minute demonstration of cloud-based daylight analysis.

It is accredited for 2 contact hours of IES/CEU's for NCQLP Certification and AIA/LU's. Instructions for requesting CEU/LU certificate will be given during the seminar.

Spaces lit with natural light have been linked with productive, healthy and happy occupants. Daylighting can be difficult without the right tools to help visualize how the sun interacts with a space. Join us to learn about ways to investigate and use daylight effectively in your designs, how occupants use blinds, and whether the levels of natural light in your space minimize electric lighting use and glare.

In this seminar we introduce different methods for looking at daylight, from renderings to IES LM-83 daylighting metrics, which have been adopted by LEED v4. These techniques can inform and help you create great daylighting in your buildings. We will discuss the strengths, limitations, assumptions and controversy over each technique, including answers to questions such as

  • Why are annual metrics necessary?
  • What do the metrics mean in terms of daylight design?
  • What qualities of daylighting do the metrics miss?
  • How does occupant behavior and the use of blinds affect both the daylighting "score" and experience of daylight?

We will go beyond reciting formulas to help you define these metrics in meaningful terms you can visualize, relate them to other techniques and understand and use them in your every-day practice. In addition, we will take a close look at the LEED v4 daylight credits (EQc7), and the differences in the requirements from LEED v2009 (IEQ c8.1).

Participating in this seminar will inform you about how to pursue the LEED daylight credits and how to use new technology to drive daylight beyond LEED. You will learn several principles and concepts of daylight analysis including solar geometry, sky conditions, annual climate data, sampling, material properties, glare and shade controls. An iterative daylight design example will illustrate trade-offs of various strategies.
