Variation in Phototopic and Melanopic Lighting in Swiss Offices: A Field Study

Marilyne Andersen, Jan Wienold, Caroline Karmann, Megan Nicole Danell, Clotilde Marie A Pierson

Health requirements for lighting in buildings are becoming increasingly important in building standards. Yet, there is a lack of concrete data on the lighting conditions that prevail in our workplaces, in terms of their spectral characteristics, their seas ...

Influence of macular pigment on the sensitivity to discomfort glare from daylight

Marilyne Andersen, Jan Wienold, Sneha Jain

Understanding the factors that influence the human perception of glare is necessary to properly address glare risks in buildings and achieve comfortable visual environments, especially in the workplace. Yet large inter-individual variabilities in glare per ...

Comparison between CIE 2° and 10° field photopic luminosity functions V(λ) for calculating daylight discomfort glare metrics

Marilyne Andersen, Jan Wienold, Sneha Jain

The spectral sensitivity of the average human eye in photopic conditions is represented by the photopic luminosity function V (λ). The CIE has established the photopic luminosity functions for the 2o and 10o visual fields for a standard observer applicable ...

User Evaluations of Contrast-Dominant Discomfort Glare Dim Daylit Scenarios: Preliminary Findings

Marilyne Andersen, Jan Wienold, Geraldine Cai Ting Quek

Discomfort glare metrics typically consider at least one of the two effects of discomfort glare-saturation and contrast-in their equation. The former occurs when there is an excessively bright glare source in the field of view, while the latter occurs when ...

Validation of Spectral Simulation Tools for the Prediction of Indoor Daylight Exposure

Marilyne Andersen, Clotilde Marie A Pierson

A growing area of research focuses on the relationship between ocular light exposure and the non-visual responses. In order to accelerate research on this topic and improve building design, reliable spectral simulation tools are needed. This study aims at ...

Raytraverse: Navigating the Lightfield to Enhance Climate-Based Daylight Modeling

Marilyne Andersen, Jan Wienold, Stephen William Wasilewski

We propose a new method for climate-based daylight modeling (CBDM) based on simulating and evaluating only the most important features. By adaptively sampling the temporal lightfield that describes daylight in buildings, our method escapes the curse of dim ...

Self-commissioning glare-based control system for integrated venetian blind and electric lighting

Jean-Louis Scartezzini, Laurent Deschamps, Ali Motamed

Rule-based control logics have proven to be efficient for automation of shading and lighting systems. However, successful commissioning of these systems for multiple stores non-residential buildings, regardless of the control logic, requires time-consuming ...

A Critical Literature Review of Spatio-temporal Simulation Methods for Daylight Glare Assessment

Marilyne Andersen, Jan Wienold, Stephen William Wasilewski, Lars Oliver Grobe

A well daylighted space can provide a highly satisfying visual environment. However, if that environment causes us visual discomfort, it can become such a nuisance that we, sometimes literally, turn our backs on this powerful connection to the outside worl ...

A smart luminaire in an office environment: impact on light distribution, user interactions and comfort

Jérôme Henri Kämpf

A smart luminaire able to change the direction of its light beam is installed in an office environment and compared to the available LEDs fixtures. Standard lighting measures are performed and a controlled user experiment is conducted, involving 22 subject ...
