Syllabus

1.Introduction to the issues, recommended reading, the possibility of using computer technology, award structures and premises, requirements. 2.Coefficient transmittance - assessment of all assigned existing structures. Calculation of thermal transmittance Uw windows. 3.Design and assessment of external walls "A" and "B" and flat roofs "C" to meet the required and recommended heat transfer coefficient according to the current wording of CSN 73 0540-2 4.Numerical and graphics solutions at all temperatures during the given structures for steady-state temperature. Assessment of the temperature factor of the internal surface of the components "A", "B" and "C" and modified components "A" and "C". 5.Approximate calculation of the coefficient of heat transfer (thermal resistance of structures), which can not be considered one-dimensional heat transfer (roof, wall timber, sandwich panel, etc.). 6.Lowest inner surface temperature structure (thermal factor inner surface fRsi) in the corners (thermal bonding, thermal bridges). Assess total of 5 parts (AB, BC, AC, BF and modified structures AC). 7.Detectionthe condensation on peripheral wall of the "A" flat roof "C". Draft vapor diffusion properties (layers with high diffusion resistance, gravel) in the peripheral wall of "A" at the bathrooms. 8.Calculation of the annual balance of evaporation and condensation of water vapor in the perimeter wall of the "A". 9.Calculation annual balance of condensation and evaporation of water in the perimeter wall or a flat roof with computer technology, an example of calculating the thermal stability in summer. 10.Temperature drop on the floor Δθ10. 11.Average heat transfer coefficient Uem calculated for a building with existing and new structures. 12.Design internal dividing walls between apartments to suit the requirements in terms of sound insulation according to the current version CSN 730532 13.Credits.
