HIGROTHERMIC TRANSFER THROUGH THE PASSIVE HOUSE AND ZERO ENERGY HOUSE ENVELOPE

Autor/autori: Lorena CARDOS, Valeriu STOIAN, Daniel DAN

Rezumat: In aceasta lucrare se va prezenta o analiza o comportarii unei punti termice in cazul unei cladiri eficiente energetic (casa pasiva sau casa zero energie), avand in vedere transferul de caldura si transferul de masa, precum si corelarea rezultatelor cu coeficientul liniar de transfer termic si riscul de producere a condensului. Detaliul analizat reprezinta o punte termica constructiva, situata la intersectia in plan orizontal dintre un perete exterior si un element vertical liniar. Se vor analiza mai multe variante de alcatuire pentru puntea termica, corespunzatoare modelului structural propus pentru cladirea considerata.

Cuvinte cheie: casa pasiva, casa zero energie, cladire eficienta energetic, punte termica, flux de caldura, risc de producere a condensului

Abstract: This paper has the purpose of analyzing the behavior of a thermal bridge in the case of an energy efficient building (passive house or zero energy building) both regarding heat and mass transfer through a selected construction section , with correlation to the linear thermal transmittance and the condensation risk. The building detail subjected to study is a geometrical thermal bridge (horizontal section through external wall at junction with vertical linear element) and will be presented in multiple detailing solutions, according to the structural system proposed for the considered building.

Keywords: passive house, zero energy house, thermal efficient buildings, thermal bridge, heat flux, condensation risk
