Students will master skills in the following fields:
1) Advanced calculations of heat resistance of building structures in the case of two-dimensional heat flow. Utilization of analogy of electric resistances
2) Solutions of Fourier’s equations of heat conduction in the case of temperature-dependent coefficient of heat conduction.
3) Calculations of heat radiation inside closed spaces (interiors).
4) Advanced calculations of combined heat transfer.
5) Advanced calculations of diffusion and condensation of water vapors in building structures.
7) Solutions of generalized Fick’s equations of diffusion in non-isothermal conditions.
6) Calculations of room accoustics.

Basic knowledge of physics, basic knowledge of mathematical analysis, basic knowledge of building thermal technology, basic knowledge of acoustics of inner spaces.

Solutions of advanced differential equations, calculations of more complicated integrals.

Teaching method of this subject is in agreement with article 7 of Brno University Technology Rules for Studies and Examinations. The method is based on a series of lectures (one hundred minute lecture per each week) and laboratory measurements (one hundred minute measurement per two weeks). In addition, students have to solve a series of rather more complicated numerical problems as their homework. The solutions of these problems are checked by the teachers in student laboratories.

The classification of students concerns practical and theoretical skills. Practical skills are evaluated on the basis of performed measurements and numerical calculations within student laboratories. Students are graded up to twenty levels there. The evaluation of their theoretical skills is realized during the examination which consists of two written tests (essay plus 4 numerical problems) and oral examination. The overall evaluation (100 levels) is converted into six grades: A, B, C, D, E, F.

1. Types of pores, porosity, absolute and relative humidity, physisorption and chemisorption.
2. Sorption isotherms after : (a) Harkins and Jury, (b) Langmuir, (c) Brunauer, Emmet and Teller (BET).
3. Three-phase system, potential of porous water, retention line of moisture.
4. Measuring methods, hysteresis of retention line, analysis of retention line.
5. Foundations of non-linear thermodynamics.
6. Phenomenological transport equations, Fourier equations of heat conduction.
7. Non-linear temperature profiles in building constructions.
