Design and Evaluation of Modular Gas and Wind Sensing Nodes for Static and Mobile Deployments

Alcherio Martinoli, Emmanuel Droz, Wanting Jin

Static and mobile sensor nodes can be employed in gas monitoring tasks to detect gas leaks in an early stage and localize gas sources. Due to the intermittent nature of gas plumes and the slow dynamics of commonly used gas sensors, measuring gas concentrat ...

Glare analysis of an integral daylighting and lighting control strategy for offices

Stephen William Wasilewski

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 ...

Electronic properties and ion migration of “in vacuo” lithiated nanoporous WO3:Mo thin films

Andreas Schueler, Josef Andreas Schuler, Luc Burnier, Jérémy Jacques Antonin Fleury

Electrochromic (EC) glazing helps manage daylight and solar heat gains in building, thereby allowing a reduction in energy consumption caused by heating, cooling, and artificial lighting. This study relates the optical and electronic properties of nanoporo ...

Theory and application of a data-driven approach to compressive spectrometry in the assessment of neurophotic stimulation

Forrest Simon Webler

Recent advances in biology and neuroscience have elucidated pathways in which visible light initiates a signaling process, via the eye, responsible for activating direct and indirect biological responses. While the full impact of unnatural light patterns o ...

A conceptual simulation workflow to guide design decisions regarding the effects of daylight on occupants' alertness

Marilyne Andersen, Clotilde Marie A Pierson, Victoria Eugenia Soto Magán

Recent developments in the lighting research field have demonstrated the importance of a proper exposure to light to mediate several of our behavioral and physiological responses. However, we spend nowadays around 90% of our time indoors with an often quit ...

Integrating non-visual effects of light in the automated daylight-responsive control of blinds and electric lighting

Marta Benedetti

The use of daylight in buildings is important because it contributes to energy savings by reducing the use of electric lighting and space heating. It also impacts on biological functions and on well-being. Indeed, light not only allows vision, but has non- ...

Validation of Spectral Simulation Tools for the Prediction of Indoor Electric Light Exposure

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

As the interest in design applications related to responses to light beyond vision is growing, two simulation tools, ALFA and Lark, have been developed to incorporate spectral characteristics of light in the evaluation of indoor lighting conditions. The sp ...

The Role of Percent Volume Buried in the Characterization of Copper(I) Complexes for Lighting Purposes

Murat Alkan

The usefulness of percent volume buried (%V-bur) as a readily quantifiable property is investigated with regard to Cu(NN)(PP) complexes of interest for lighting purposes. Photoluminescence quantum yields (PLQYs) and single crystal X-ray structures of ...
