A Critical Comparison of Annual Glare Simulation Methods

Marilyne Andersen, Jan Wienold

Recently, there have been multiple proposals for faster methods to calculate glare metrics, daylight glare proba- bility (DGP) in particular. This is driven simultaneously by the lengthy times required to simulate DGP with a con- ventional image-based appr ...

Window Size Effects on Subjective Impressions of Daylit Spaces: Indoor Studies at High Latitudes Using Virtual Reality

Marilyne Andersen, Jan Wienold, Kynthia Chamilothori

Daylight provision to the indoor space is affected by different building elements that cannot be fully controlled by the users, such as the window size of a space. The dimensions of the fenestration not only affect the lighting levels, but they also affect ...

Effect of Indoor Temperature and Glazing with Saturated Color on Visual Perception of Daylight

Marilyne Andersen, Jan Wienold, Giorgia Chinazzo

This paper presents the combined effect of indoor temperature (19 degrees C, 22 degrees C, and 26 degrees C) and colored glazing (blue, orange, and neutral) on visual perception of daylight. Experiments were performed in an office-like test room, in which ...

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 ...

Environmental preferences of occupants: A multi-domain approach in the Swiss open office case study

Marilyne Andersen, Jan Wienold, Dusan Licina, Dolaana Khovalyg, Caroline Karmann, Verena Marie Barthelmes, Arnab Chatterjee

Defining indoor environmental conditions that meet the needs and preferences of occupants in open space offices can be challenging since the same space might be occupied by people with different individual needs and preferences regarding what constitutes a ...

On Sensitivity to Glare and Its Relationship with Macular Pigment

Marilyne Andersen, Jan Wienold, Sneha Jain

Current trends in discomfort glare research have suggested the influence of physiological parameters on individual glare perception. To this end, we hypothesize that a specific ocular physiology characteristic, namely the macular pigment (MP) in the retina ...

Global Environmental Stimuli and Human-Building Interaction in Open Space Offices: A Swiss Case Study

Marilyne Andersen, Jan Wienold, Dusan Licina, Dolaana Khovalyg, Caroline Karmann, Verena Marie Barthelmes, Arnab Chatterjee, Maria Viviana Gonzalez Serrano

Office employees are exposed to a variety of environmental and contextual stimuli that might drive them to perform control actions, such as operating windows or window blinds. These actions have a significant impact on building energy use and increase unce ...

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 ...

Glare assessment in a daylit workplace from a physiological perspective

Marilyne Andersen, Jan Wienold, Sneha Jain

Designing the buildings that facilitate optimum utilization of daylight is desirable for its many benefits [1], [2] yet challenging due to other intrinsic properties of daylight responsible for over-heating and discomfort glare [3]. Discomfort glare has be ...

Subjective assessment of visual comfort in a daylit workplace with an electrochromic glazed facade

Jan Wienold, Caroline Karmann, Sneha Jain

Electrochromic (EC) glazing is increasingly employed in building facades to achieve better visual comfort for the occupants. EC glazing can modulate the light entering through the facade by varying the solar transmittance of the glass and therefore can wor ...
