Shaping of Selected Elements for A Low Energy Building

Reaching the standard of low energy building requires fulfilling criteria of energy saving and thermal protection as well as humidity criterion on design and exploitation stages. The basic factors shaping energy saving construction include among other: building architecture, construction and material solutions of external partitions and building joints using modern thermal insulation materials (building casing), type and efficiency of ventilation, central heating and hot water preparation systems and integral management of a building in energy production. In this work, there is an analysis of shaping of selected elements for low energy consumption. Physical parameters of selected external partitions and joints were defined using professional computer programs taking into account external and internal air parameters. Additionally, there was presented the influence of installation systems efficiency and energy source used on demand factor for non-renewable primary energy EP. Based on performed calculations and analyses, there were formulated design, executive and exploitation guidelines in shaping of building elements for low energy consumption buildings. (paper)
