Subject aims expressed by acquired skills and competences

Learning outcomes of the course unit the aim of the course is to acquaint students with the possibilities of design of heating systems for low-energy and passive construction and buildings with almost zero energy consumption. They will be acquainted with the evaluation of heating systems from a technical, economic and functional point of view, they will be able to determine the investment and operating costs of individual heating systems and the ways of their regulation. Part of this is to point out the connection between the design of the building technical systems and the partial energy supplied in the energy performance of the building, including practical calculations. On the basis of the realization documentation, he acquires the content and scope of the project documentation of heating with an emphasis on completeness and quality of execution. They are able to build technological schemes for combining different heating sources using renewable energy sources.
