Transparent structured conductive coating for applications in smart windows.
Solar radiation reaching the surface of the earth for a period of one hour contains more energy than that consumed by mankind over an entire year. Some of this solar energy is already collected by photovoltaic cells to cover the electricity needs of buildi ...
EPFL2023Novel microwave transparent low emissivity coating for energy-efficient glazing: towards 5G frequencies
Andreas Schueler, Luc Burnier, Jérémy Jacques Antonin Fleury
Novel mobile communication technology such as 5G will provide a more efficient and reliable platform for the development of the Internet of Things. However, microwaves in the range of 5G frequencies are strongly attenuated by modern energy-efficient glazin ...
IOP2019Experimental demonstration of three-fold wavelength multicasting of a 64-QAM 120 Gbit/s data channel using a Kerr frequency comb and nonlinear wave mixing
Tobias Kippenberg, Maxim Karpov, Martin Hubert Peter Pfeiffer, Arne Kordts, Fatemeh Alishahi, Ahmad Fallahpour
We experimentally demonstrate three-fold wavelength multicasting of a 64-quadrature-amplitude-modulation (QAM), 120-Gbit/s data channel using a microresonator Kerr frequency comb and nonlinear wave mixing. The multicasting is achieved with a data signal an ...
SPIE-INT SOC OPTICAL ENGINEERING2019Development of a novel mechanical micro-engraving method for the high-aspect-ratio microstructures of an advanced window system
André Gabriel Kostro, Josef Andreas Schuler, Jing Gong, Antoine Robert Michel Delaunay
A transparent polymer film with embedded micro mirrors is developed, and it can be attached to a window glass pane for daylighting, improving visual comfort and reducing cooling load in buildings by redirecting sunlight. Despite existing cutting-edge techn ...
2018Windows and renovation: The case of 19th century ordinary housing in Switzerland
Luca Ortelli, Catarina Wall Gago, Peter Zurbrügg
Ordinary residential buildings dating from late nineteenth century and early twentieth century are an essential part of the European urban built environment. Today, it is important to address the comfort of residents through renovations improving the build ...
Green Lines Institute for Sustainable Development2016Efficient Algorithms for the Data Exchange Problem
Michael Christoph Gastpar, Sameer Pawar
In this paper, we study the data exchange problem, where a set of users is interested in gaining access to a common file, but where each has only partial knowledge about it as side-information. Assuming that the file is broken into packets, the side-inform ...
Institute of Electrical and Electronics Engineers2016Microstructured glazing for daylighting, glare protection, seasonal thermal control and clear view
The appropriate choice of glazing in a facade depends on many factors. They include amongst other criteria: location, orientation, climatic condition, energetic efficiency, usage of the building, required user comfort, and the architectural concept. On the ...
EPFL2015Recursive Compressed Sensing
Martin Vetterli, Nikolaos Freris, Orhan Öçal
We introduce a recursive algorithm for performing compressed sensing on streaming data. The approach consists of a) recursive encoding, where we sample the input stream via overlapping windowing and make use of the previous measurement in obtaining the nex ...
Submitted to IEEE Transactions on Information Theory2013Urban Form Optimization for the Energy Performance of Buildings Using Citysim
The energy efficiency of the urban texture relies notably on the buildings’ form, which characterizes its capability to take profit of the solar potential as well as its loss of energy through the envelope. Therefore, the general layout at the district sca ...
EPFL Solar Energy and Building Physics Laboratory (LESO-PB)2013Solar shading and its influence on daylight and well-being
This talk will provide current research perspectives on shading systems, on how their performance can be evaluated and on what the implications are on comfort and health. In particular, the latest results from an ongoing research project conducted at the L ...
