While there is a growing use of complex facade designs in contemporary architecture worldwide and across Europe, little is known about the perceptual effects of these facades and the resulting daylight patterns on occupants, or about how such effects might ...
Ce projet s’inscrit dans le cadre du développement d’une centrale solaire thermique de faible puissance (2-10 kW). La quantité d’énergie produite par toute centrale solaire, thermique ou photovoltaïque, dépend de la quantité de flux lumineux capté. Un syst ...
This work discusses solar power towers and especially the simulation and optimization of heliostat fields. The technological stateof the art is given through typical characteristic values and dimensions of some existing central tower power plants such as t ...
Automated shading systems have the potential to exploit daylight in buildings to save energy of artificial lighting and cooling loads and improve occupants'f visual comfort. This paper investigates the daylighting performance of automated Venetian blinds b ...
Air mass factors (AMFs) are used in passive trace gas remote sensing for converting slant column densities (SCDs) to vertical column densities (VCDs). AMFs are traditionally computed with 1D radiative transfer models assuming horizontally homogeneous condi ...
A new physically based method to estimate hemispheric-directional reflectance factor (HDRF) from lightweight multispectral cameras that have a downwelling irradiance sensor is presented. It combines radiometry wilh photogrammetric computer vision to derive ...
We present an analysis of the hemispherical-directional reflectance factor (HDRF) of snow, using 16 seasonal datasets of the spectral range from 400 to 2,500 nm. The data was measured under clear sky conditions in Davos Dorf (Grisons, Switzerland, 1,560 m ...
This guide provides the IES required uniform method for determining and reporting the photometric characteristics of skylights and tubular daylighting devices. It describes the procedures followed and the precautions observed in obtaining uniform and repro ...
