Contributions to the transfer of heat and mass into brick walls with vertical holes

The paper presents the analysis of heat and mass transfer in brick walls with vertical holes, type of envelope widely used in the construction of residential dwellings in Romania. Moving towards the concept of passive house leads to the sealing of the envelope as much as possible, leading to complex mass transfer phenomena. The analysis of winter mass transfer phenomena for buildings in climate areas II, III for such a type of envelope leads to conclusions that can be used for solutions that lead to high energy efficiency in conditions of interior comfort and fulfillment of parameters leading to the occupants' health.
