Ocular light exposure has important influences on human health and well-being through modulation of circadian rhythms sleep, as well neuroendocrine cognitive functions. Prevailing patterns do not optimally engage these actions for many individuals, but advances in our understanding the underpinning mechanisms emerging lighting technologies now present opportunities to adjust promote optimal physical mental performance. A newly developed, international standard provides a SI-compliant way quantifying influence intrinsically photosensitive, melanopsin-expressing, retinal neurons that mediate effects. The report recommendations lighting, based an expert scientific consensus expressed easily measured quantity (melanopic equivalent daylight illuminance (melaponic EDI)) defined within this standard. are supported by detailed analysis sensitivity circadian, neuroendocrine, alerting responses ocular provide straightforward framework inform design practice.

At its best, human-centric lighting considers the visual and non-visual effects of light in support positive human outcomes. worst, it is a marketing phrase used to healthwash products or design solutions. There no doubt that environmental contributes health, but how might one practice given both credible potential implausible hype? Marketing literature filled with promises. Technical societies have summarized science not yet offered guidance. Meanwhile, designers are middle, attempting distinguish knowledge from which dubious make decisions affect people directly. This article intended to: (1) empower reader fundamental understandings ways affects health; (2) provide process for can dovetail decision-making already part designer's workflow.

Since the non-image-forming (NIF) effect of daylight on human circadian system is widely accepted, adequate exposure to now considered one elements a healthy life. In urban environment, prerequisites for adequately lit indoor spaces amount and quality reaching window, which highly dependent characteristics environment. The aim study was determine whether there are correlations between density (i.e., distance buildings, building height), façade surface colour Window-to-Wall Ratios – WWR) NIF potential daylight. conducted parametric geometric model street canyon covering wide range characteristics.

This paper reports the results of a systematic review conducted on articles examining effects daytime electric light exposure alertness and higher cognitive functions. For this, we selected 59 quantitative research from 11 online databases. The protocol was registered with PROSPERO (CRD42020157603). showed that both short-wavelength dominant intensity white induced alertness.
