Capillary rising damp in Venetian context: state of the art and numerical simulation

Abstract The fragility of Venice and its buildings are linked to the floods, observed since ancient times and emphasized in recent years: the periodic sea level rise, accompanied by rising damp, are the main causes of the alteration. In particular, the rising damp causes a series of complex diseases in the historic buildings, such as physical decay, chemical or biological, with loss of aesthetic and economic value. In addition, greater heat dispersion and reduced thermal comfort can also occur in interior spaces, with consequent risks for human health. This is a sign of “Sick Building Syndrome”. It is very important to develop models for assessing the vulnerability of assets and to manage sustainable plans related to maintenance processes and activities, satisfying the requirements of effectiveness and compatibility. Basing on numerical models performed with the WUFI 2D software, the paper analyses the different behavior of rising damp in relation to materials or masonry structures. In particular, the construction techniques and typical materials used in Venetian buildings were investigated, such as clay brick walls, lime plaster, Marmorino and Cocciopesto, adopted mainly to limit the capillary rise also caused by the phenomenon of “acqua alta”.

This paper presents the negative impacts on residential buildings in Kosovo, - as well as the main factors of the occurrence of sick building syndrome (SBS) in residential buildings in the case of Kosovo. It also examines the impact of different materials on this phenomenon and how many constructions in Kosovo are protected from this phenomenon. For the assessment of the impact of materials on health and the environment, it is necessary to consider all the phases. Starting from the phase of construction, selection of materials, application from the beginning of the use of the building, including all the materials processing from the beginning until their application, the use of natural resources for the production of various construction products, the necessary energy for the production and processing of the materials used, and the amount of release and imitation of CO2 (carbon dioxide). This paper also discusses the question of what sick building syndrome SBS is, how materials are affected by this phenomenon, what are the main materials affecting the residential buildings in SBS phenomenon in Kosovo, what buildings are affected by this phenomenon and how does this phenomenon affect human health. Furthermore, this paper provides a deep analysis on factors influencing the phenomenon of SBS in different municipalities and several companies. It also discusses the influence of Asbestos and its impact on SBS, through a survey conducted in different municipalities and institutions and other companies. Through this discussion the paper attempts to provide information on the current knowledge about asbestos, as well as the manner of its assembling and dismantling, storage and all other information related to this material which has a great impact on the appearance on phenomena of SBS. A special emphasis has been put on the impact of materials on our health, recent research on the materials used and impact on the appearance of SBS case, including the diseases that occur as a consequence of the occurrence of diseased buildings.
