Selected aspects of design for internal partitions and construction joints in low energy consumption buildings – a case study

Sustainable building is construction approach which is friendly to both humans and the environment, saving natural resources and counteracting pollution. The most essential design and execution features in this kind of construction approach include: the use of renewable energy sources to preserve natural resources; lowering the energy consumption of technological processes; decreasing the amount of material waste (by changing or modernising the building material technologies used); limiting of energy consumption of existing buildings and those being designed; modern installations in buildings; computer aid in sustainable building design.

This paper presents principles for the design of external partitions and their joints using innovative thermal and insulation materials regarding their thermal and humidity requirements. Integral design elements in this range include certified computer programs which use numerical calculations allowing for parameters of external and internal air. The introduction of new thermal and insulation materials has a crucial impact on processes inside partitions and building joints. That is why the choice of a material layers system should be based on individual calculations considering 'the specifics of the situation in which it will be applied. Based on the performed calculations and analyses, certain recommendation regarding design and execution were formulated in this paper for design of low energy buildings.
