SENSITIVITY STUDY OF ANNUAL AND POINT-IN-TIME DAYLIGHT PERFORMANCE METRICS: A 24 SPACE MULTI-YEAR FIELD STUDY
With the latest published version LEED (v4), and the
IES codifying two recommended annual-climate-based
daylighting metrics and performance criteria, annual
daylighting simulation has become even more
important to the design professions than ever before.
However, interpretation and application of annualclimate-based
daylighting data are still relatively novel.
This paper documents a 8-year human factors
daylighting field research project using students’
qualitative assessments of daylight sufficiency and
corresponding point-in-time and annual-climate-based
daylighting simulation in a variety of building types
(n=24) in order to provide insight to the building
performance simulation community about application
of these new annual daylighting metrics.
