The purpose of the research is to find adequate solution against rising damp in historical buildings. The improvement in this case is the use of ventilated air channels. A special group of historical buildings are churches because they do not use routines as for example museums, galleries. We designed 4 differently constructed ventilated air channels. These are: open or closed, with overpressure and underpressure. As a verification we use a relevance to these constructions which we simulated in software Ansys CFX the air flow of channels. We modelled the equal segments of the channels. The best solution of these constructions are the ventilated air channels with underpressure system. In this solution we measured the highest values of air velocity. Nevertheless this solution is not an aesthetic form of construction, because the pipes are set on the facade. But these pipe are put inside the drainage pipe. This research should offer the solution for architects against problems of rising damp in historical buildings. To find the right solution is necessary to research every case. The aim of the research is to prepare the design process of the ventilated air channels for the architects without the simulation of every building, cross section or geometry of the construction.

For find the right solution is necessary to research everyone case.

The selection of building materials is one of the most important issues in the phase of building design. This decision has impact on the energy performance of the building as well asits indoor environmental quality. Energy needed forthe extraction, processing and transportation of materials used in building structures can be a significant part of the total energy within the entire life cycle of the building. The environmental impacts are expressed by indicators such as embodied energy, CO2eq and SO2eq emissions. The aim of this analysis is to identify the environmental quality of material compositions of exterior walls. [ABSTRACT FROM AUTHOR]
