This thesis introduces a new approach to characterize and evaluate ocular light exposure based on the discovery of novel blue light-sensitive photoreceptors in the human eye. These photoreceptors are the primary mediators of 'non-visual' responses impactin ...

Human circadian, neuroendocrine, and neurobehavioral responses to light are mediated primarily by melanopsin-containing intrinsically-photosensitive retinal ganglion cells (ipRGCs) but they also receive input from visual photoreceptors. Relative photorecep ...

Daylit architecture is perceived as a dynamic luminous composition, yet most existing performance metrics were designed to evaluate natural illumination for its ability to adequately illuminate a two-dimensional task surface and avoid glare-based discomfor ...

Daylight is valued as an energy efficient alternative to electric light and over the past few decades, climate-based horizontal illuminance metrics have demonstrated the importance of variable sky conditions on annual predictions. These metrics allow us to ...

This paper introduces a novel approach for the assessment of daylight performance in buildings, venturing beyond existing methods that evaluate 2-dimensional illumination and comfort within a fixed field-of-view in order to predict human responses to light ...

This paper presents a proof-of-concept for a goal-based simulation structure that could offer design support for daylighting performance aspects beyond conventional ones such as illumination, glare or solar gains. The framework uses a previously establishe ...

In spaces where daylight is a primary source of illumination, our visual perception of architecture is largely influenced by the ephemeral composition of sunlight and shadow. To evaluate these perceptual effects, the authors will apply quantitative contras ...

This paper introduces an interactive web-based visualizer for multi-metric daylight simulation results, named OCUVIS. It is able to display simulation-based results for a diverse range of ocular human-centric metrics such as non-visual health potential (nv ...

The discovery of a novel non-rod, non-cone photoreceptor in the human eye that mediates a number of effects on the brain has sparked a growing interest in incorporating these non-visual effects of light into the design process of buildings. Appropriately–t ...

The discovery of a novel non-rod, non-cone photoreceptor in the mammalian eye that mediates a range of ‘non-visual’ responses to light has required reexamination of how lighting needs for human health are characterized and evaluated. Existing literature pr ...

This paper will present an annual simulation-based workflow for assessing human perceptual and non-visual responses to daylight across a series of view positions in an architectural case study. Through the integration of mathematical models used to predict ...
