Optimizing Daylighting: Exploring Visual and Non-Visual Effects through Weather, Orientation, and Location
Abstract
This paper presents a comprehensive analysis of daylight performance in a standard office across twelve different locations. The assessment covers both the visual and non-visual impacts of daylight, taking into account aspects such as vision, glare, view quality, and circadian rhythms. Evaluation criteria are based on the prerequisites for daylight and view credits outlined in LEED v.4 [1], in conjunction with the WELL 2.0 Building Standard [2] for daylighting evaluations. The assessed space is outfitted with sidelight windows, representing a typical section of an office within a multi-story building. The study's findings shed light on how daylight performance is influenced by geographical location, prevailing weather conditions, window dimensions, shading devices, glass transmittance, and floor plate depth. Notably, the study demonstrates the feasibility of designing spaces that meet the daylight and view credit criteria of LEED v.4 while complying with the circadian lighting requirements of WELL 2.0 in diverse locations. Achieving this goal relies on implementing window systems that provide ample bright light while employing minimal window size and shading devices to control glare at occupants’ eye level.
