Analytical meanders of selected systems for thermo-renovation of historical buildings

Abstract

The article contains an analysis of selected systems for thermorenovation of vertical partitions in protected buildings. Historical buildings often require thermo-renovation, but in practice their "insulation" can be applied only internally on partitions without decorations. Internal thermorenovation methods can be classified according to heat exchange and moisture transport. For the purpose of this paper, the methods were analysed in terms of diffusion-open and diffusion-closed systems, and compared in a multi-variant aspect. The calculations were made assuming a wall with the moisture content up to 3%, a wall with the very high moisture content up to 11%, and for a wet wall with a constant inflow of water due to capillary action. They attempted to evaluate the effectiveness of various thermo-modernisation treatments in building partitions in the aspect of protection against permanent moisture growth, mould development and improvement of their overall heat protection, considering the 8-year time interval. Several different sets of materials were included in a multivariate analysis, as well as various scenarios of the possible effects of their use. The paper is summarised with conclusions regarding the effectiveness and risk related to the application of different internal methods of thermo-renovation of partitions.

“…They also indicated that it is not necessary to conduct extremely dense scans, which consequently translates into saving time otherwise required for making measurements. The moisture analysis of historic buildings should be carried out thoroughly, the best results are obtained by conducting in situ examinations [49]. Mycological tests reveal the presence of various species of fungi, in particular toxicogenic and wood-degradable species.…”

Diagnosis of the Technical Condition of Historic Tenement Houses as the First Stage of Revitalisation of the City

“…In the case of revitalisation of historic tenement houses, the scope of activities largely depends on the state of preservation of the historic place [10]. All actions should be preceded by a diagnosis of the technical condition of buildings, taking into account historical changes in building development [5][6][7][8][9][11][12][13][14]. Diagnostics of individual buildings will allow determining the scale of needs in the revitalisation programme [1][2][3][5][6][7].…”
