“…Collected data are valuable due to the fact that their accumulation can be very time-consuming and that they can be used later in many ways, such as input data for simulation tools or as a data-mining analyses source. The need of a convenient data storage solution is present across the scientific fields [1][2][3], including materials engineering [4,5].…”

Numerical simulation of heat, moisture, salt and momentum transport is often applied for the investigation of building materials, nowadays. However, the results would not be satisfactory without credible and precise input data for the computations. Therefore, the results of laboratory experiments have to be stored and shared. In this paper, we focus on the material parameters of historical masonry in the manner of a system for their storing and utilization. To provide the data in a sufficient and safe way, make it accessible across the computer platforms and realize a connection between the experimental measurements, its circumstances and performers, a web-based database system is designed. It provides a solution to several issues: data backup and sharing, ensuring uniformity and serviceability on separate yet easy accessible storage. The database offers the descriptions, prescriptions, references and values of parameters of materials arranged in several categories. The online PHP application is based on the MVP concept with RMD-type MySQL database equipped by data conversion and interpretation tools. The contents of current version were measured and consolidated on the Department of Materials Engineering and Chemistry, Faculty of Civil Engineering, Czech Technical University in Prague. Several characteristic examples of the practical application of the database are presented, demonstrating its capability to act as an effective tool for the computational assessment of degradation of historical masonry

“…Material parameters of autoclaved aerated concrete were taken from the material database of Department of Materials Engineering and Chemistry, FCE CTU in Prague [9]. The system is based on PostgreSQL type of database with PHP application, a solution well proven in general computer systems, but also in materials science [10]. For the tested structure, thermal transmittance (U-Value) and thermal resistance (R-Value) were calculated according to [11], assuming the thickness of the autoclaved aerated concrete wall of 375 mm.…”

The construction of latent-heat-storage building envelope systems often involves an application of interior and/or exterior plasters with enhanced thermal storage properties. In this paper, cement-lime plasters with incorporated phase change material (PCM) are designed and the effect of the applied PCM on their heat storage capacity is analysed using the measurement of basic physical, mechanical and thermal parameters. Among the basic physical properties, bulk density, matrix density and total open porosity are measured. Mechanical resistivity of the developed plasters is characterized by compressive and flexural strength and dynamic Young's modulus. Thermal conductivity and thermal diffusivity are measured using the transient pulse method. The temperature dependent specific heat capacity is accessed using differential scanning calorimetry (DSC) in cooling, as well as heating regime. On the basis of the experiments performed, the supposed improvement of the energy efficiency of characteristic building envelope system where the designed plasters are likely to be used is evaluated by a computational analysis. The results of computer simulations are very promising for the future use of the designed system in the building sector.

The Eco-MCPS database is a web-based database system that includes environment-friendly materials, components, products, and services. The text data stored in the Eco-MCPS was analyzed by text-mining showed that eco-product environmental performances are realized by the use of environment-friendly components or materials. The access log of Eco-MCPS was subjected to data mining, and the association analysis suggested that there are item relations formed by the user interest. Based in these results, it is suggested that the enhancement of collaboration between manufacturers and material or component suppliers improves the development of environment-friendly products and provides the "suggesting function", thereby promoting this collaboration.
