Abstract(s)
Instead of standard building materials, alternatives are gradually being used more and more in construction. One of these alternatives is a lightweight wall systems using the cement panel AQUAPANEL® OUTDOOR. The investigated system is characterized by heterogeneity, which is determined by its design features. The possibility of using light systems as enclosing structures of buildings should be confirmed by calculations of thermo-physical parameters of the construction. As features of constructive solutions for the external walls with the use of cement boards, namely the presence of a metal or wooden frame, massive wall elements require special attention and supporting calculations for thermal resistance. Research on the joint work of elements of light systems, in compliance with the requirements of thermal protection during the operation of buildings, will allow determining the degree of influence of these systems on the sanitary and hygienic parameters of thermal protection. Investigation of thermal protection characteristics of complete systems on new or reconstructed objects, taking into account the influence of defects of building envelope structures, allows quantitatively determining the compensatory capacity of reducing the energy consumption of each system. An analysis of the efficiency of the use of light systems will allow assessing the economic effect of using one or another system from the point of view of reducing operating costs. Objective: 1. Consider the actual data, works and literature on this theme;
2. Build two different testing walls which represent light systems;
3. Conduct research to determine the thermal heterogeneity of the systems; 4. Conduct an analysis of the walls with two thermal imaging devices; 5. Run a computer simulation of the heat transfer process and compare the results with the real results;
6. Conduct a feasibility study comparing with the traditional solutions.
