Daylight, in which we evolved, is naturally rich in the blue component of the spectrum and has key properties when it comes to impacts on body functioning. Current lifestyles are driving the emergence of a 24-hour society that spends most of the time indoors (around 90%), where lighting conditions are a result of design and operation priorities derived from both comfort and energy criteria, which often lead to reduced access to daylight (smaller or shaded openings) to manage solar gains and glare risks. This may result in an insufficient (day)light exposure in daily life from a physiological perspective, light being an essential cue to properly entrain our internal circadian clock and increase subjective alertness. But it is still unclear whether it can have a significant beneficial effect when compared to artificial light from a psychophysiological standpoint. Most of the studies on acute alerting effects have been conducted in well-controlled laboratory settings, where somewhat extreme and narrowly defined lighting conditions have been tested. This paper proposes assessment and monitoring techniques that would apply to semi-controlled studies instead, and focuses on the impact of daylighting in work settings by exploring ways to investigate alertness neurobehaviour and physiology in realistic indoor conditions.

This study aims to reveal the preferable lighting condition on the appearance of woman’s facial skin. We conducted an experiment on the appearance of woman’s face with and without makeup under some lighting conditions. The facial skin conditions of the female model consisted of three patterns, without makeup, with makeup in orange and with makeup in pink. Participants evaluated face appearance in terms of “naturalness,” “activity”, “sophistication” and “preference”. According to the results, the facial skin without makeup and with “natural” makeup look good under 4000K and 5000K in negative duv, and facial skin of all types looks active under 3000K. In addition, the evaluations of activity of the face without makeup correlated with the preference index for Japanese complexion PS, whereas other evaluations of preference have no correlation with PS.

This paper shows an photometer spectral response measurement method using an pulsed tunable laser.The laser is the comparator. the standard detector is a three-silicon S1337 trap detector and the detector under test is a silicon photodiode with a V(λ)-correction filter. Due to the low noise and strong signal of the laser, we believe it will give a lower measurement uncertainty compared to traditional method for measuring S(λ) of the photometer

Light-emitting diode (LED) is considered to be one of the feasible light source in the future. The combination of LED and architecture puts forward new requirements for Building Lighting Integration (BLI) design. This paper is concerned with the development of the BLI design software that based on Building Information Modelling (BIM) technology. Application Programming Interface (API) and Format Conversion of Information (FCI) are believed as the two main technologies during this process. In the development process, the two main technical problems with Revit as the core part are discussed. Design suggestions were given for form and lamp component library of the BLI design software that need to be designed.

The final goal of this study is to build a total appearance model for human perception of the qualities of a material. To achieve this objective, we propose physical indices for modelling perception with regard to glossiness, transparency, and roughness by investigating the relationship between measurable physical properties and the appearance of real materials in this study. In our physical measurements and subjective evaluations, we used 34 stimuli exemplifying ten material categories. As a result, we found physical indices corresponding to subjective perception as follows: (1) The index of perceptual gloss correlates to a nonlinear transform of physical glossiness. (2) The index of perceptual transparency corresponds to the luminance difference of material surfaces with white vs black backgrounds. (3) The index of perceptual roughness correlates to the edge intensity detected from the captured images.
