Abstract
V zaključnem delu smo primerjali različne vplive robnih pogojev na izračunane dinamične toplotne lastnosti gradnikov ovoja stavb v numerični simulaciji s pomočjo Excela. Te dinamične toplotne lastnosti smo primerjali z vrednostmi po SIST EN ISO 13786:2017. Podatke smo izračunali za navidezni dan z različnimi vrednostmi sevanja in za realen jasen dan v Ljubljani. Ugotovili smo, da z numeričnim modelom pri istih robnih pogojih, kot so opredeljeni pri SIST EN ISO 13786:2017 dobimo enake vrednosti za faktor dušenja in časovni zamik toplotnega toka. Ugotovili smo, da ni bistvene razlike v izračunanih podatkih s spreminjanjem količine maksimalnega dnevnega sevanja. Ugotovili smo, da ni bistvene razlike v izračunanih podatkih za realen jasen sončen dan v numerični simulaciji, če upoštevamo sončno sevanje ali pa ne. Ugotovili smo, da so dinamične toplotne lastnosti konstrukcij z ozelenjenimi strehami veliko boljše kot pa konstrukcij brez ozelenjenih streh.

Title:
The influence of outer boundary conditions on the thermal dynamic characteristics of elements of the building envelope
Abstract:
The thesis compares the effect of different boundary conditions on the calculated dynamic thermal characteristics of the building envelope. We calculated the various dynamic thermal characteristics using numerical simulations in Microsoft Excel. We compared these dynamic thermal characteristics to those calculated using SIST EN ISO 13786:2017. We calculated the data for a hypothetical day with various solar radiation values and for a real clear day in Ljubljana. We have found that using the numerical model we get the same values for the decrement factor and the time shift as with SIST EN ISO 13786:2017. We have found that there is no fundamental difference in the numerical simulation when we change the boundary conditions for solar radiation. We have found that there is no fundamental difference in the calculated values for the real clear sunny day in the numerical simulation with or without the added boundary condition of solar radiation. We have found that the dynamic thermal characteristics of buildings with green roofs are much better than those of buildings without green roofs.
