Determination of the construction and the material identity values of outside building components with the help of in‐situ measuring procedures and FEM‐simulation calculations. The aims formulated nationwide and internationally to the climate protection can be achieved by combining of the energy‐efficient construction and rehabilitation of the existing buildings. Knowledge about the construction and the material identity values of the warmth‐transferring outside components is a condition for the energetic balance of buildings. The essential information to this can frequently be no more taken from the construction documents particularly for older buildings since they are no longer traceable or incomplete. At the example by univalve and bivalve out‐wall construction it is shown that the thermophysical qualities can be determined with the help of in‐situ measuring procedures and FE‐simulation calculations without destruction. 相似文献

Bei großflächig verglasten, mehrgeschossigen Bürogebäuden liegen doppelschalige, hinterlüftete Glasfassaden nach wie vor im gestalterischen Trend. Die Konstruktionsdetails der Fassade haben einen erheblichen Einfluss auf die sommerliche Überhitzung der Luft im Fassadenzwischenraum (FZR), in dem auch der Sonnenschutz platziert ist. Es empfiehlt sich daher, die Details einer doppelschaligen Fassade im Hinblick auf die sommerlichen Temperaturverhältnisse zu optimieren. Die üblichen Methoden einer standardmäßigen bauphysikalischen Planung sind für eine derartige Optimierung nur sehr bedingt verwendbar. Im vorliegenden Beitrag wird anhand des Projektes Neues K & H Bank‐Gebäude in Budapest exemplarisch aufgezeigt, wie mit Hilfe von moderner Simulationstechnik die Ausbildung einer doppelschaligen Fassade evaluiert und anschließend optimiert werden kann. Evaluation and optimization of a double skin façade with the help of computational simulations. Natural ventilated double skin façades still prove to be trendy design choices for multi‐story office buildings with large glazed surfaces. The construction design details of these façades have a significant impact on the summer overheating of the air in the façade cavity, in which the shading is positioned also. Therefore it is recommended to investigate and optimize the parameters of the double skin façade concerning the summer temperature conditions. The usual methods of standard building physical planning have limited application possibilities for optimizing these kinds of systems. Therefore in the following article through the example of the K°&°H Bank, Budapest, we are going to explain how the modern simulation techniques can support the constructional design of double skin façades first by evaluation, then subsequently, by optimization. 相似文献

Germany has set ambitious targets at a national level for the reduction of emissions with the Energiekonzept 2010: by 2020, emissions should be reduced by at least 40 % compared to 1990. By 2050, a reduction of emissions by 80 to 95 % (compared to 1990) is intended [1]. In order to even come near to these targets, the energy‐related refurbishment of existing buildings has been gaining significance for some years. Facades that are worth preserving or under listed building protection limit the upgrading options on the outside, but interior insulation solutions are as ever regarded with suspicion by some protagonists. The following article reports on the building physics support for a particularly challenging refurbishment project. 相似文献

This article illustrates the solid building envelope both as an integral system and in terms of its potential for additive manufacturing. The Façade Research Group at the TU Delft works on the building envelope, investigating strategic and process support for development and planning processes and renovation technologies, as well as functionally integrated building envelopes. The Institute of Structural Mechanics and Design at the TU Darmstadt undertakes research and development in the areas of materials technologies (glass, polymers) and additive manufacturing as they relate to building structure. 相似文献
