Daylight and carbon interactions: An explorative method to reconcile daylight performance and carbon budget constraints

Marilyne Andersen, Nazanin Rezaei Oghazi

Existing daylight standards encourage larger glazed areas, which often results in larger solar gains in the summer and heat losses in the winter. To avoid these, shadings, thicker frames and multiple panes of glass are required to respect operational energ ...

Applying Visible Difference Prediction to View Visibility

Marilyne Andersen, Stephen William Wasilewski

This paper presents a preliminary model for relating the optical characteristics of different dynamic shading systems to the visibility of the view through these systems. View visibility is dependent on the optical properties of the façade, the incident li ...

Identification of Spectral Distributions in Light-Dosimetry Data: Methodology and Application to an Intervention Field Study

Marilyne Andersen, Steffen Lutz Hartmeyer

Modern life in predominantly indoor environments has led to a profound alteration in the amount, spectral distribution, and pattern of light humans are exposed to daily. Given the role of light in health and well-being, and to understand how modern living ...

T-Shaped Interdisciplinarity: A Model for Applied Research?

Marilyne Andersen

Challenges ahead: how the conduct of research needs to change The emergence of scientific discovery at the interface of disciplinary fields is not necessarily driven by the academic system - rather, discovery happens despite it. Marilyne Andersen (EPFL) co ...

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 ...

Risk of incorrect choices due to uncertainty in BPS evaluations of conceptual-stage neighbourhood-scale building designs

Marilyne Andersen, Luisa Pastore, Minu Agarwal

At the conceptual stage, building performance simulation (BPS) based evaluations are being increasingly used for tasks such as ranking of competing massing design proposals. However, such conceptual stage evaluations suffer from information deficiency in b ...

Saliency prediction in 360° architectural scenes: Performance and impact of daylight variations

Marilyne Andersen, Sabine Süsstrunk, Kynthia Chamilothori, Bahar Aydemir, Caroline Karmann, Seungryong Kim

Saliency models are image-based prediction models that estimate human visual attention. Such models, when applied to architectural spaces, could pave the way for design decisions where visual attention is taken into account. In this study, we tested the pe ...

User assessment of fabric shading devices with a low openness factor

Marilyne Andersen, Jan Wienold, Caroline Karmann

Providing adequate glare protection and a view to the outside through fabric shading devices is challenging because these two objectives require conflicting material properties for a fully lowered shading. In a semi -controlled office-like experiment invol ...

Dynamism in the context of views out: A literature review

Marilyne Andersen, Caroline Karmann, Yunjoung Cho

Previous studies have shown that access to a satisfactory view to the outside with sufficient daylight is essential for building occupants' health and well-being. It has also been suggested that certain features of visual content improve view-out quality, ...
