HYGROTHERMAL PROPERTIES OF HISTORIC BRICKS FROM VARIOUS SITES OF LATVIA
There are available hygrothermal simulation tools that allow to model possible scenarios for optimization of thermal transmittance of historic wall, creating complex insulation systems. The accuracy of the results depends on the conformity of the input data to the specific design of existing wall. The properties of materials selected in the simulation tool should reflect as close as possible the properties of the wall under investigation. For theses tools to be widely applicable the material library has to include various materials from various regions, thus allowing architects, planners, real estate developers and homeowners of Latvia to use the simulation tool with greater reliance on the accuracy of the simulation results. In order to obtain a result in mathematical modelling software simulating the humidity transfer processes, which would reflect the situation as close to the real conditions as possible, the database built into the modelling software should be supplemented with materials specific to the Latvian construction periods and obtained in different locations. Dataset Contains hygrothermal parameters of 40 different historic brick samples from Latvia (Density, Porosity, Water vapor resistance factor, etc.). Standard measurement methods with some adjustments were used to determine hygrothermal parameters of brick samples. The material properties were determined for a specific reason, to be used as a input data for creation of hygrothermal simulation tool material file, in this case DELPHIN simulation tool. Therefore, some deviations from the testing standards were implemented. These deviation were developed by Dresden University of Technology (also the developers of DELPHIN simulation tool) and are described in file "description.docx".
