Three-dimensional finite element method in the heat analysis of buildings

  • In the present paper, the usage of the finite element method in analysis and improvement of energetic efficiency of buildings is demonstrated on the simple example of inhomogeneous wall suggested by the European Committee for Standardization. It was shown that described method may be considered chip, efficient and more precise than standard “hand-out” calculations. In addition, it was shown that it enables a wide opportunities in the process of designing of new buildings and evaluation of its thermal behavior. With the simple change of input parameters as material characteristics, geometry and boundary values, its influence on the building’s over all behavior is analyzed and optimized, regardless of the type of complexness of geometry and type of thermal load, with simultaneous visualization of the temperature and heat flux field.
