Integrating non-visual effects of light in the automated daylight-responsive control of blinds and electric lighting

The use of daylight in buildings is important because it contributes to energy savings by reducing the use of electric lighting and space heating. It also impacts on biological functions and on well-being. Indeed, light not only allows vision, but has non- ...

Validation of Spectral Simulation Tools for the Prediction of Indoor Electric Light Exposure

Marilyne Andersen, Clotilde Marie A Pierson, Myrta Gkaintatzi-Masouti

As the interest in design applications related to responses to light beyond vision is growing, two simulation tools, ALFA and Lark, have been developed to incorporate spectral characteristics of light in the evaluation of indoor lighting conditions. The sp ...

Does glazing color influence our perception of discomfort glare from daylight?

Sneha Jain

Spectrum and correlated colour temperature of light are shown to influence human visual comfort. Previous research conducted with electric light, mainly in the context of vehicular headlamps, have demonstrated that coloured LEDs induce more discomfort glar ...

Data-driven optimization of building layouts for energy efficiency

Andrew James Sonta

One of the primary driving factors in building energy performance is occupant behavioral dynamics. As a result, the layout of building occupant workstations is likely to influence energy consumption. In this paper, we introduce methods for relating lightin ...

The Role of Percent Volume Buried in the Characterization of Copper(I) Complexes for Lighting Purposes

Murat Alkan

The usefulness of percent volume buried (%V-bur) as a readily quantifiable property is investigated with regard to Cu(NN)(PP) complexes of interest for lighting purposes. Photoluminescence quantum yields (PLQYs) and single crystal X-ray structures of ...

Calibration and Validation of Climate-Based Daylighting Models Based on One-Time Field Measurements: Office Buildings in the Tropics

Geraldine Cai Ting Quek

Calibrated climate-based lighting simulation models of buildings have the capacity to perform an essential role in postoccupancy evaluations, such as annual frequency assessments of daylighting quality and visual discomfort. However, in most postoccupancy ...
