Talk: VSS VIENNA young SCIENTISTS SYMPOSIUM, TU Wien; 2018-06-07 - 2018-06-08; in: "VSS - Venna young scientists symposium", P. Hans, G. Artner, J. Grames, H. Krebs, H. Mansouri Khosravi, T. Rouhi (ed.); Book-of-Abstracts, (2018), ISBN: 978-3-9504017-8-3; 74 - 75.

In recent years, many efforts have been undertaken to investigate potential energy-efficient renovation solutions for existing buildings, especially in case of historical buildings. Applying
thermal insulation systems to exterior building envelope is one of the most common strategies to reduce building energy use. In this regard, using new insulating nano-material with special hygrothermal properties, such as Aerogel, has become increasingly common worldwide. This paper describes the result of a case study on application of various finishing layers on Aerogel plaster,
which were applied on the external layer of a retrofitted construction. Silica Aerogel is an open-cell nano-material that is suitable for applications where particularly high thermal insulation properties are desired[1]. An insulation coating based on silica Aerogel has a minimal impact on the thickness of the walls, and is a lightweight refurbishment system with high
thermal performance (low thermal conductivity, i.e. 0.014 W.m-1K-1, and low density, about 3 kg.m-3)[2]. In addition to the thermal performance, the hydrophobic behavior of an Aerogel based
material is useful in building renovation. Applying the rendering on the external surfaces reduces or eliminates the undesirable consequences of condensation and moisture problems within the wall
structure[3].
