This study evaluates the performance and robustness of 22 established newly proposed glare prediction metrics. Experimental datasets daylight-dominated workplaces in office-like test rooms were collected from studies by seven research groups six different locations (Argentina, Denmark, Germany, Israel, Japan United States). The variability experimental setups, teams allowed reliable evaluation metrics for workplaces. Independent statistical methods applied to individual also one combined...
The discovery of a novel non-rod, non-cone photoreceptor in the mammalian eye that mediates range ‘non-visual’ responses to light has required reexamination how lighting needs for human health are characterised and evaluated. Existing literature provides useful information about quantify non-visual spectral sensitivities but optimal approach is far from decided. As more learned underlying biology, new approaches will continue be published. What currently lacking flexible framework describe...
Daylit architecture is perceived as a dynamic luminous composition, yet most existing performance metrics were designed to evaluate natural illumination for its ability adequately illuminate two-dimensional task surface and avoid glare-based discomfort. It may be argued that task-driven approaches based on glare ignore the likelihood contrast can provide positive impacts our visual perception of space. Advances in these accommodate climate-based sky conditions occupant behaviour have...
This paper details the results of an experimental study investigating combined effect indoor temperature (19 ℃, 23 ℃ and 27 ℃) horizontal illuminances (∼140 lx, ∼610 lx ∼1440 lx) on visual perception, with daylight as only source light. The goal is to evaluate cross-modal unimodal perception daylight. A 3 × mixed-design experiment was conducted in office-like test room 84 participants. Results show that effects occurred: Temperature influenced perceived warmth daylight, interacted...
Recent studies have shown that the façade and light patterns in a space are an important factor occupants' experience, but little is known about generalizability of these findings different lighting conditions, uses space, or latitudes. This study employed virtual reality to investigate effects geometry daylight on impressions physiological responses (skin conductance, heart rate, rate variability), while simultaneously examining effect sky type, spatial context, latitude participant...
This paper describes a climate-based simulation framework devised to investigate the potential for non-visual effects of daylight in buildings. It is part 2 study where first focused on formulation photobiological underpinnings threshold-based model configured lighting from perspective human system (e.g. circadian response). employs static dose–response curve and instantaneous exposure at eye estimate magnitude effect as step towards that would establish link between light an architectural...
Discomfort glare is a major challenge for the design of workplaces. The existing metrics discomfort prediction share limitation that they do not take gaze direction into account. To overcome this limitation, we developed ‘gaze-driven’ method assessment. We conducted series experiments under simulated office conditions and recorded participants’ using mobile eye tracking luminance distributions high dynamic range imaging methods. two methods were then integrated to derive ‘gaze-centred’...
An accurate knowledge of the directional optical properties advanced fenestration materials is necessary for them to be adequately integrated in buildings. These are expressed by Bidirectional Transmission (or Reflection) Distribution Functions (BTDF, BRDF) such elements, which measured specifically designed measuring equipment: an innovative, time-efficient bidirectional goniophotometer, based on digital imaging techniques, was and set up that purpose. In this paper, in-depth validation...
This work discusses the use of digital cameras fitted with absorption filters as quasi-spectral radiometers. By filtering incident light into selected wavelength intervals, accurate estimates radiances can be made for unknown spectra. approach is being employed part a new video-projection goniophotometer to study properties angularly and spectrally selective complex fenestration systems. Complex systems are increasingly used distribute solar radiation purposefully in buildings. They utilized...

It operates in near-IR spectral region (950-2020nm) as a photometer spectrometer. instrument composed of: cold (135 K) optomechanical subsystem consisting Silicon carbide structure, an optical assembly, filter wheel mechanism, grism calibration unit, thermal control system, detection system based on mosaic 16 H2RG with their front-end readout electronic, warm electronic (290 data processing / detector...
The aim of this study was to develop a small-scale model system resembling the micro- and meso-structure butter, namely having water-droplet size distribution water content close that commercially produced butter. Although it is possible churn cream on small scale, matching microstructure butter challenge. A 2-step churning process introduced with application kitchen mixer. resulting evaluated using confocal laser scanning microscopy. In addition, low-field nuclear magnetic resonance used...
Abstract In accordance with the Paris agreement, Swiss Climate Strategy (SCS) defines net-zero target to be reached before 2050, which demands for a thoughtful carbon budget allocation between different contributors. Ongoing normalization tasks are currently defining life cycle budgets at building scale aligned SCS. While recent research has provided promising methodologies break down whole building’s budget, SCS-aligned cannot calculated component yet. Having ability define components’...
Current view representation methods for Virtual Reality (VR), monitors, and projection screens predominantly rely on static photographs tone-mapping operators without temporal variations, limiting the exploration of dynamic features in a view. Capturing views with real-time video overcomes this limitation but has limited range relies an unverified built-in process. This study investigates adequacy reliability using real- time captures daylit VR. To evaluate suitability camera's procedures,...
Health requirements for lighting in buildings are becoming increasingly important building standards. Yet, there is a lack of concrete data on the conditions that prevail our workplaces, terms their spectral characteristics, seasonal variation, influence orientation or chosen blind control strategy, and how they might impact occupants’ well-being. The objective this study to start addressing gap by offering insights into kind environments typical Swiss open-plan offices provide occupants...
Discomfort glare from daylight can lower productivity and hinder effective use of in buildings. Existing prediction models have limitations accounting for the large inter-individual differences, mainly due to unknown physiological factors underlying discomfort glare. Our study aims determine whether macular pigment optical density (MPOD) human retina influences individual sensitivity indoor daylit environments. We conducted user studies involving 149 participants office-like settings,...
