Traversing Time Dependent Light Fields for Daylight Glare Evaluation
To understand how daylight gives shape and life to architectural spaces, whether existing or imagined, requires quantifying its dynamism and energy. Maintaining these details presents a challenge to simulation and analysis methods that flatten data into di ...
EPFL2023Tuning the Solar Performance of Building Facades through Polymer 3D Printing: Toward Bespoke Thermo-Optical Properties
Stephen William Wasilewski, Arno Schlueter
Facades are the primary interface controlling the flow of solar energy in buildings and affecting their energy balance and environmental impact. Recently, large-scale 3D printing (3DP) of translucent polymers has been explored as a technique for fabricatin ...
WILEY2023Tone-mapping requirements in real-time videos for studying the dynamism of views-out in virtual reality
Marilyne Andersen, Caroline Karmann, Stephen William Wasilewski, Yunjoung Cho
Current view representation methods in VR predominantly rely on static photographs and tone-mapping operators without temporal variations, limiting the exploration of dynamic features in a view. This study presents an alternative workflow to capture dynami ...
2023Using raytraverse to render high accuracy images
Raytraverse is a python based software that helps to efficiently organize and guide the sampling of a lighting simulation within a scene. Radiance is embedded within Raytraverse to provide accurate and efficient solutions for each sampled ray. This talk wi ...
2023Glare analysis of an integral daylighting and lighting control strategy for offices
Complex Fenestration Systems (CFSs) can significantly impact both the visual and non-visual daylight effects on the occupants as well as the energy performance of buildings. To ensure that those impacts improve the overall situation, proper control algorit ...
2023Modeling reflection by structured building-integrated photovoltaics
Evaluating the reflection of solar radiation by Building Integrated Photovoltaics (BIPV) with structured front-glass is challenging for two reasons. First, the resulting irregular scattering of light cannot be accounted for by simple reflection models. Sec ...
2023Efficient 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 ...
2022Tutorial: Raytraverse for Annual Glare Assessment
In this tutorial the basic usage of raytraverse to complete annual glare simulation tasks is covered. Raytraverse is a software for managing and speeding up the simulation of daylight in building. ...
2022Comparing Annual Glare Simulation Methods
Recently, there have been multiple proposals for faster methods to calculate glare metrics, daylight glare probability (DGP) in particular. This is driven simultaneously by the lengthy times required to simulate DGP with a conventional image-based approach ...
