doi:10.18086/eurosun.2014.08.13
A new method was developed to measure the spectral radiance of all sky elements using a general purpose digital camera with a circular fisheye lens. The method provides sufficient accuracy for solar energy applications such as daylighting design, photosynthesis analyses and photovoltaic evaluations. The instrument is portable for field measurements in various climates. The digital camera with the fisheye lens is colorimetrically calibrated using a xenon lamp and a spectroradiometer to obtain the calibration functions which transfer the video signal values RGB on a digital color image into the absolute values of CIE 1931 tristimulus values XYZ pixel by pixel. The calibrated fisheye digital camera measures the all sky distribution of the XYZ tristimulus values which are also useful for measuring all sky distributions of luminance and correlated color temperature. The XYZ tristimulus values are transferred into the all sky spectral radiance distribution using the eigenvectors obtained by principal component analysis of spectral radiance data of sky elements measured by a spectroradiometer under various weather conditions. The accuracy of the method is experimentally validated by comparing with the spectral radiance of sky elements measured by the spectroradiometer.

EuroSun 2014 proceedings now online!
Dear Dr. Uetani,
We are pleased to announce that the proceedings of International Solar Energy Society (ISES) EuroSun 2014 conference are now published and available online in a new ISES open access online database at http://proceedings.ises.org/. All accepted papers are freely accessible and have been assigned a Digital Object Identifier (DOI).
This website is a new service of ISES to provide access to proceedings of ISES conferences. The EuroSun 2014 papers are the first conference proceedings published. Proceedings from other ISES conferences, such as select past and upcoming Solar World Congresses and EuroSun events will be added to the website database.
For more information: www.eurosun2014.org Date:
September 16-19, 2014 Venue:
Aix-les-Bains, France A conference of: ISES Conference host: INES Contact:

Papers can be searched by title, author or topic. In addition, all papers from the EuroSun 2014 can also be downloaded as a complete PDF file or as individual papers in a ZIP file.
We hope you enjoy the proceedings and this new service of ISES.
Kind regards,
Dr. Elimar Frank
Chair of the Scientific Committee, President ISES Europe

EuroSun 2014 EuroSun 2014: International Conference on Solar Energy and Buildings Aix-les-Bains, France 16 - 19 September 2014 www.eurosun2014.org
EuroSun 2014, the ISES European regional solar energy conference, was organised by ISES Europe and ISES jointly with the Institut National de l'Energie Solaire (INES), CEA and PSE AG. The EuroSun 2014 brought together leading scientists, engineers, architects, and representatives from industry and business to discussed the latest research results, technological developments and business opportunities in solar energy. The main themes explored during this conference were solar energy and buildings, fundamental pillars to achieving a transition to a renewable energy society.

Search all papers by keyword, author, event... ISES Conference Proceedings Database Welcome to the International Solar Energy Society (ISES) Conference Proceedings Database. On this website you can search and find papers published under the proceedings of ISES conferences. Each paper is published with a unique Digital Object Identifier (DOI). This database offers the global renewable energy community with easy and searchable access to ISES conference proceedings. It also provides authors of scientific papers a state-of-the-art platform to publish their work presented at ISES conferences. ISES was founded in 1954 to advance solar energy technology development and use. Since then ISES has led the growth of solar energy from the laboratory to commercial success. ISES conferences, such as the biennial Solar World Congress and EuroSun, exemplify the spirit of international networking and exchange of ideas. Our conferences provide a unique opportunity for knowledge sharing and networking opportunities for the global renewable energy community, representing the research and academic sectors, governments, civil-society and project and community planners among many others. The proceedings represent the latest in research, development, deployment and projects on a range of topics presented at ISES conference. Topics covered include: Renewable Electricity Technologies: Photovoltaics, Concentrated Solar Power (CSP), Biomass, Geothermal, Wind, Hydro, Ocean and Other Solar Heating and Cooling Solar Buildings and Architecture Resource Assessment and Energy Meteorology Energy Storage Renewable Energy Grid Integration and Distribution Off-Grid and Rural Energy Access Solar Energy and Society Clean Transportation Technologies and Strategies
The papers published under each conference are sorted according to the themes and topics defined under each event. Papers are published according to the events at which they were presented by the authors. They can be searched by theme, author, or title. Each paper published in this online database was presented at an ISES conference by the authors, and reviewed by the respective scientific committee members for that event. All the papers published here are open access, thus free of charge. Complete versions of the conference proceedings are also available as PDF to download.
CrossRef ISES is a member of CrossRef, an association of scholarly publishers that develops shared infrastructure to support more effective scholarly communications. CrossRef is the official DOI registration agency for scholarly and professional publications. All papers in the ISES proceedings database are assigned a DOI number and registered with CrossRef.
How can you support our work? ISES offers access to the proceedings and papers published here free of charge. As a non-profit, membership organisation, we rely on members’ support to offer this and other services.
