A Passive House (PH) system is not only an opportunity but also a necessity for the further development of sustainable eco-buildings. Construction of the foundation in energy-efficient houses is the key to maintaining low energy losses. The appropriate selection of building materials requires considering the thermal conditions of the environment, including its location and the zero isotherms in the ground. The main objective of this work is to analyze the possibilities of designing foundations for PHs in Poland, according to the current methodological data. In order to realize the basic aims, the work was divided into the following materials and methods: (I) literature review; (II) database of PH in Central Europe; (III) method of depth of ground freezing determination; (IV) selection of the joint of slab-on-ground foundation and external wall to analysis; (V) description and validation of the heat-transfer model. The result of the research work is: (i) analysis of the foundation under the conditions of freezing of the ground in Poland; (ii) description and validation of the heat-transfer model. The research has revealed that in the Polish climate zone, the most efficient solution for passive buildings is to build them on a foundation slab. The foundation of a building below the latest specified ground frost depths in Poland is inefficient in terms of, for example, thermal insulation, economics, and the idea of PH.
Artykuł prezentuje analizę posadowienia oraz wytyczne do projektu konstrukcji chłodni kominowej w elektrowni konwencjonalnej. Zaprezentowano ogólną charakterystykę konstrukcji, główne założenia projektowe oraz opis warunków gruntowo-wodnych na rozpatrywanym obszarze. Następnie omówiono zakres i główne założenia analizy. Otrzymane na podstawie analizy wyniki prezentują podsumowanie rozważań projektowych związanych z wyborem ostatecznie przyjętego sposobu posadowienia. Ostatecznie uzyskano zoptymalizowany rozkład współczynnika podatności sprężystej podłoża, wraz z przewidywanymi wartościami osiadań po obwodzie fundamentu chłodni kominowej.
