Circadian Stimulus Calculator
Now that Symmetry is available with a fully tunable color spectrum, I thought I’d share an amazing new tool to help you with your circadian lighting needs. No, it’s not a good night’s sleep, but it might just help you get there.
The Lighting Research Center at Rensselaer Polytechnic Institute released a free Circadian Stimulus (CS) calculator to help lighting professionals select light sources and light levels that will increase the potential for circadian-effective light exposure in architectural spaces, utilizing the CS metric. The CS metric is a new way to quantify light’s impact on acute melatonin suppression, a marker for circadian system activation.
The CS calculator can be downloaded from the LRC’s website here for your use www.lrc.edu. They also list some handy “look-up charts” to help you identify the right design direction to take.
The LRC’s Mark Rea and Mariana Figueiro recently published a paper in Lighting Research & Technology detailing how the model works. You can view the paper here: Lighting Research & Technology (for purchase).
For a more easily understood breakdown of how it all works, click below to view the article Designing with Circadian Stimulus published by LD&A last year.
