Abstract

This publication focuses on the assessment of the impact of structural solutions of single-family buildings with an increased energy standard on their air-tightness level. The first part presents the threats resulting from the low tightness of the building. To formulate the conclusions, quantitative and qualitative casing tightness tests of existing single-family energy-efficient buildings were carried out. Construction and material solutions used in buildings were also analysed. The obtained results indicate that there is no impact of the building structure on its level of air tightness.

Highlights

The implementation of the principles of increasing the energy efficiency of buildings promoted in the world results in the need to minimize energy losses in buildings
Negative examples leading to the increase of the actual energy demand in relation to the design assumptions can be considered as too low level of air tightness of the building [1, 2]
The level of air infiltration is influenced by the number and size of critical places in the building envelope, construction materials used and combinations of components of different construction

Summary

Introduction

The implementation of the principles of increasing the energy efficiency of buildings promoted in the world results in the need to minimize energy losses in buildings. Negative examples leading to the increase of the actual energy demand in relation to the design assumptions can be considered as too low level of air tightness of the building [1, 2]. This dependence was presented, among others in the article [3], in which the authors prove that improving the tightness, in an energy efficiency building, may cause a 25% decrease in the demand for energy for heating and ventilation. The level of air infiltration is influenced by the number and size of critical places in the building envelope, construction materials used and combinations of components of different construction
