The Effect of Boundary Conditions to Specify the Energy Performance of Buildings

The overall energy performance of buildings is determined not only based on structural and material solutions of the building. Boundary conditions affect the results of evaluation of the energy performance too. This paper deals with buildings in the Czech Republic. The paper is devoted to the evaluation of energy performance of buildings under changing boundary conditions. This means the change of the intensity of ventilation, changes in the structures’ accumulation and influence of thermal connections.
