Perceived glare from the sun behind tinted glazing: Comparing blue vs. color-neutral tints

Marilyne Andersen, Andreas Schueler, Jan Wienold, Maxime Lagier, Sneha Jain

While the influence of a glare source's spectrum on sensitivity to discomfort glare has been demonstrated repeatedly under electric light conditions, it has not yet been studied under actual daylit conditions. To investigate the influence of spectral alter ...

Towards a framework for light-dosimetry studies: Quantification metrics

Marilyne Andersen, Steffen Lutz Hartmeyer

Light dosimetry aims to measure personal light exposure with wearable sensors, which is a complex multistep procedure. The resulting data may be used to investigate non-visual effects of light in real-life settings, to validate laboratory findings and answ ...

Comparison of questionnaire items for discomfort glare studies in daylit spaces

Marilyne Andersen, Jan Wienold, Clotilde Marie A Pierson, Geraldine Cai Ting Quek, Sneha Jain, Caroline Karmann

When studying discomfort glare, researchers tend to rely on a single questionnaire item to obtain user evaluations. It is unclear whether the choice of questionnaire item affects the distribution of user responses and leads to inconsistencies between studi ...

Towards ‘Fourth Paradigm’ Spectral Sensing

Marilyne Andersen, Forrest Simon Webler, Manuel Spitschan

Reconstruction algorithms are at the forefront of accessible and compact data collection. In this paper, we present a novel reconstruction algorithm, SpecRA, that adapts based on the relative rarity of a signal compared to previous observations. We leverag ...

Window View Quality: Why It Matters and What We Should Do

Marilyne Andersen, Caroline Karmann

We lack consensus on a unified definition for window view quality that is applicable across occupancies and building types. In addition, while this is a topic of growing interest, there is limited research underway due to its complex nature, insufficient f ...

The spectral sensitivity of human circadian phase resetting and melatonin suppression to light changes dynamically with light duration

Marilyne Andersen, María Lovísa Ámundadóttir

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 ...

In-situ evaluation of high-performance glazing based on illuminance and glare

Marilyne Andersen, Jean-Louis Scartezzini, Andreas Schueler, André Gabriel Kostro, Jan Wienold, Pietro Florio, Caroline Karmann

High-technology glazing panes are designed to meet the need for natural light, while optimizing key functions such as reducing solar heat gain in spaces and/or redirecting daylight to the rear of the spaces. However, the actual performance in terms of both ...

Efficient Simulation for Visual Comfort Evaluations

Marilyne Andersen, Jan Wienold, Stephen William Wasilewski

This paper provides a validation of a novel sampling, storage, and evaluation method named raytraverse that can quickly and accurately compute glare and visual comfort metrics including vertical illuminance, Daylight Glare Probability (DGP), and Unified Gl ...

Measurement in the Age of Information

Marilyne Andersen, Forrest Simon Webler

Information is the resolution of uncertainty and manifests itself as patterns. Although complex, most observable phenomena are not random and instead are associated with deterministic, chaotic systems. The underlying patterns and symmetries expressed from ...

Impact of Brightness on Glare Perception when Using Shading Fabrics

Marilyne Andersen, Jan Wienold, Caroline Karmann

Access to daylight and views out are usually recognized as beneficial to occupant comfort at the workplace. Simultaneously, discomfort glare due to direct sunlight is a known source of occupant dissatisfaction. Shading fabrics with low openness factor have ...

A simulation tool for building and lighting design considering ipRGC-influenced light responses

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

The ipRGCs in the human eye mediate several effects on people, such as alertness and circadian rhythms. The spectral, temporal and spatial characteristics of light influence the magnitude of these effects. To facilitate the anticipation of the ipRGC-influe ...

Transmittance thresholds of electrochromic glazing to achieve annual low-glare work environments

Marilyne Andersen, Jan Wienold, Sneha Jain

A recent study on the glare protection performance of electrochromic (EC) glazing showed that visible transmittance levels lower than 0.6% are necessary to achieve comfortable situations for sun positions, that were close to the central field of view. Howe ...

The influence of façade and space design on building occupants’ indoor experience

Marilyne Andersen, Luisa Pastore

Existing research on user’s satisfaction at the workplace have shown that occupants’ perceived comfort depends on a number of environmental and non-environmental factors and that forgiveness, meant as the indulgent attitude towards inadequate indoor enviro ...

Regional Differences in the Perception of Daylit Scenes across Europe Using Virtual Reality. Part II: Effects of Facade and Daylight Pattern Geometry

Marilyne Andersen, Kynthia Chamilothori, Jan Wienold

While there is a growing use of complex facade designs in contemporary architecture worldwide and across Europe, little is known about the perceptual effects of these facades and the resulting daylight patterns on occupants, or about how such effects might ...

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 ...

Subjective and physiological responses towards daylit spaces with contemporary facade patterns in virtual reality: Influence of sky type, space function, and latitude

Marilyne Andersen, Kynthia Chamilothori, Jan Wienold

Recent studies have shown that the facade and light patterns in a space are an important factor in the occupants' experience, but little is known about the generalizability of these findings in different lighting conditions, uses of space, or latitudes. Th ...

Regional Differences in the Perception of Daylit Scenes across Europe Using Virtual Reality. Part I: Effects of Window Size

Marilyne Andersen, Kynthia Chamilothori, Jan Wienold

The size of window openings is widely acknowledged as an important factor in our spatial perception. However, little is known about how the perception and preference of windows changes between countries, leaving a gap of knowledge regarding the applicabili ...

Effect of window glazing color and transmittance on human visual comfort

Marilyne Andersen, Jan Wienold, Sneha Jain

: Occupants’ visual comfort in an indoor space strongly depend on the quantity and quality of the daylight inside the space which can be altered with the type of window glazing. In this study, we compared the visual comfort perception of participants with ...

Evaluating the suitability of regression-based emulators of building performance in practice: a test suite

Marilyne Andersen, Parag Rastogi

Building Performance Simulation (BPS), a useful tool to assess the operational performance of buildings and systems, can often be computationally expensive. The use of BPS is cumbersome for problems where the speed of response is important, e.g. real-time ...
