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.

Permanent increase of energy prices leads to the construction of new houses in the low-energy and passive standard. In particular, the development of wooden buildings in recent years has experienced a boom and their positive qualities are coming to the attention of potential investors. Thanks to this the new technologies of construction are still being developed and the new wood-based materials tested. All of these materials and technologies must follow the standards which tightened the thermal technical requirements.

The aim of the contribution is to confirm or rule, by using non-parametric Kruskal Wallis test, the hypothesis published [1] that the construction type and building materials have not statistically relevant effect on the final building airtightness. For non-parametric test is used the same sample as in [1], where the impact of construction type on the airtightness is refused by using parametric test - one way analysis of variance (ANOVA).
