Description: Das Projekt "Innovative glazings for high solar gains and daylighting" wird vom Umweltbundesamt gefördert und von Fraunhofer-Institut für Solare Energiesysteme durchgeführt. General Information/Objectives: The objectives of this project are to develop advanced window systems with a widely variable solar transmittance, a low u-value (smaller than 1.1 W/m2K) and in special cases improved day lighting performance. In order to meet the objectives, different new technologies will be pursued and integrated into one system. Thus the main task is to develop: (1) highly transparent coatings with low thermal emittance in order to achieve glazings with uvalues smaller than 1.1 W/m2K (2) a switching system with a very wide dynamic range for the transmittance modulation (between 0.7 and 0.05) (3) broad-band antireflection layers with a gain in solar transmittance of at least 5 per cent per pane (4) daylight directing and distributing components with a maximum efficiency higher than 40 per cent. Technical Approach New materials and production technologies are available on a small scale in research laboratories. During the project these new materials and technologies have to be combined to build up new window systems. The scaling up will be done in close cooperation with the consulting industrial companies. At the end of the project a decision has to be made as to which technologies will be available for large scale industrial production. Complete systems will be constructed, characterised and tested. In close cooperation with industry and architects, the appearance and technical acceptance will be tested and the cost of the systems analysed. Expected Achievements and Exploitation In the course of the project, results in the different fields will be presented at conferences and discussed with the scientific world. Positive feedback from outside will be included in the project. At the end of the project the results will be presented in a special workshop during Eurosun II, which will be held in Ljubljana in September 1998. For this workshop, a short summary of the final report will be available. The workshop will be organized by the industrial partners so that they can demonstrate their interest in this field. Depending on the success of the project, demonstration projects are planned within the THERMIE Programme afterwards.
