This is an excerpt about the importance of metrics from Daylight Metrics: The What, How, and Why Should I Care.
This is a past event.
Understanding the metrics of daylight performance is crucial to the design and operation of any lighting system that hopes to integrate daylight. In 2013, the Illuminating Engineering Society approved a method to calculate a new set of climate-based daylight metrics to evaluate daylit spaces: Spatial Daylight Autonomy and Annual Sun Penetration. This method has been adopted in LEED v4.0 and is expected to be utilized by other consensus-based codes and standards that promote better daylit spaces.
These metrics, based on research and occupant/expert assessments for real spaces, provide designers a tool to more effectively describe, evaluate, and improve the performance of their daylighting designs.
