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

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

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 ...

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 ...

Strong coloration of nanoporous tungsten oxides by in-vacuo lithiation for all-solid-state electrochromic devices

Andreas Schueler, Anna Krammer, Maxime Lagier, Olivia Valérie Charlotte Bouvard, Luc Burnier

Electrochromic windows allow for an improved management of solar heat gains in buildings and enhanced visual comfort of building users. All-solid-state electrochromic devices can be especially durable. During their fabrication lithium has to be inserted, p ...

Color neutral nanocomposite nickel-tantalum oxide for electrochromic windows

Andreas Schueler, Josef Andreas Schuler, Olivia Valérie Charlotte Bouvard

Electrochromic windows can darken on demand to limit the solar gains entering a building to reduce the risk of overheating, while preserving the view towards the exterior. Yet, the switching speed and contrast as well as the durability of commercial produc ...

Coatings with tailored electronic and optical properties for advanced glazing

Olivia Valérie Charlotte Bouvard

Modern envelope glazing relies on nanoscale coatings to meet a range of specific needs. Low emissivity coatings can improve the thermal performance of glazing thanks to a thin metallic film. However, the conductive nature of this layer leads to an attenuat ...

EPFL Smart Glass Field Study

Marilyne Andersen, Forrest Simon Webler, Victoria Eugenia Soto Magán

The objectives of this study are to evaluate (1) direct non-visual effects of red-impoverished daylight on circadian resetting and alertness and (2) the daily light-exposure pattern on indirect–circadian–effects. The novelty of this study is that it will b ...

Development and characterization of electrochromic oxide and ion conductor deposited by reactive magnetron sputtering

Andreas Schueler, Olivia Valérie Charlotte Bouvard, Djamel Eddine Mansour

In order to modulate the solar gains of a building, electrochromic windows can be used. To improve their durability, inorganic solid state electrolytes are considered. This work reports on the investigation of tungsten trioxide (WO3) and lithium phosphorou ...
