SOLABS: Development of a Novel Solar Thermal Facade Cladding System

Christian Roecker, Maria Cristina Munari Probst

Within the European project SOLABS (Development of unglazed coloured solar absorbers) a novel performing unglazed metal collector has been developed, using a coloured absorber and with special focus on the architectural integration of the solar system. The ...

Sol-gel deposition and optical characterization of multilayered SiO2/Ti1-xSixO2 coatings on solar collector glasses

Christian Roecker, Jean-Louis Scartezzini, Andreas Schueler, Estelle De Chambrier

Thin films of silicon oxide and silicon titanium mixed oxides are deposited on solar collector glazing in a sol–gel dip-coating process based on alcoxide precursors. Spectrophotometry is used to characterize the relation of film thickness and withdrawal sp ...

Sol-gel deposition of nanostructured low refractive index materials on solar collector glazing

Christian Roecker, Jean-Louis Scartezzini, Estelle De Chambrier, Josef Andreas Schuler, Dipanwita Dutta

Nanoporous SiO2 and nanocomposite MgF2:SiO2 coatings have been deposited by sol gel dip-coating in a particle-free atmosphere. The refractive index of the prepared nanostructured thin films is determined from spectrophotometric data. In both cases, signifi ...

Potential of quarterwave interference stacks for colored thermal solar collectors

Christian Roecker, Jean-Louis Scartezzini, Andreas Schueler

2005

Thin film multilayer design types for colored glazed thermal solar collectors

Christian Roecker, Jean-Louis Scartezzini, Andreas Schueler, Estelle De Chambrier

Multilayered inteference filters of dielectric thin films have been designed for the application as energy-efficient coloration of collector cover glasses. The optical behavior of the designed multilayers is analyzed by computer simulations yielding the CI ...

Angle-dependent spectrophotometry of Sol-Gel deposited multilayered oxide coatings on solar collector glasses

Christian Roecker, Jean-Louis Scartezzini, Andreas Schueler, Estelle De Chambrier, Dipanwita Dutta

Multilayered thin oxide films have been deposited on solar collector glazing by sol-gel dip coating in a dust-free environment provided by a laminar flux chapel. A superior film quality and a satisfying film homogeneity have been achieved for the produced ...

Architectural integration of solar thermal collectors: results of a European survey

Christian Roecker, Andreas Schueler, Maria Cristina Munari Probst

A survey has been conducted as part of the European project SOLABS (unglazed coloured solar absorbers for building facades) to provide the design team with a set of formal design guidelines. Targeted mainly at European architects of the three climatic regi ...

Design of a time-efficient video-goniophotometer combining bidirectional functions assessment for transmission and reflection

Marilyne Andersen, Christian Roecker, Jean-Louis Scartezzini

A detailed knowledge of the light distribution characteristics through advanced window systems is required to improve the visual comfort of the building's occupants while controlling the propagation of daylight in rooms and the solar gains. An innovative b ...

Integration and formal development of solar thermal collectors

Christian Roecker, Maria Cristina Munari Probst

The paper presents selected results of an investigation over possible ways to improve Building Integrated Solar Thermal systems (BIST) on the formal level. It shows the results of a European survey intended to help defining quality in the architectural int ...
