Kuhn, Tilmann E.Tilmann E.Kuhn2022-03-032022-03-032007https://publica.fraunhofer.de/handle/publica/21447910.1002/bapi.200710012A general method for realistic performance evaluation of solar control properties of facades with sun-shading or other solar control systems has been developed. It is particularly designed to be used for venetian blinds. It can be used 'stand-alone' or within building simulation programs. The new method has proven to be of great practical value to planning teams of huge office buildings in Germany, Austria and Switzerland. The method is presented in detail in [4]. It can be used either 'stand-alone' (without building simulation) for comparisons of different facade variants or within building simulation programs. In this publication the extension of the methodology for the case of facades with solar control systems between the panes of an insulating glazing unit (IGU) is presented. Some parts of the proposed methodology could be used in standards (e. g. EN 13363) or to improve the accuracy of building simulation programs which are currently on the market Practical experience with the new methodology led to insights which are the basis for the design of two new products. These new products are compared with state of the art products in [5] on the basis of the new methodology. We are currently linking the new method with the building simulation program ESP-r in a project which is funded by the Veluxstiftung.de621690journal article
