2D-toplotna analiza stavbnega ovoja na podlagi 3D-modela : diplomska naloga = 2D thermal analysis of a building envelope on the base of a 3D model : graduation thesis
Bizjak, Dejan, gradbenik, 1990-
Diplomsko delo zajema toplotno analizo stavbnega ovoja s pomočjo programskega orodja THERM 7.5. Ovoj stavbe je bil izrisan v programu AutoCAD s pomočjo oblaka točk, pridobljenega z laserskim ...skeniranjem. Izrisani so trije profili stavbnega ovoja z različno stopnjo členjenosti: profil, ki predstavlja idealiziran stavbni ovoj (minimalno členjen); profil, ki predstavlja model obravnavane stavbe; in profil, ki predstavlja realno stanje na podlagi oblaka točk iz 3D-skeniranja. Za vsakega izmed profilov je bilo modeliranih 6 križanj, ki so bila analizirana v THERMu. Križanja so geometrijsko modelirana v skladu s SIST EN ISO 10211:2017. Rezultati 2D-toplotne analize so prikazani v obliki izoterm, termografskega izrisa toplotnega polja, vektorjev toplotnega toka in z intenzivnostjo toplotnega toka. Na podlagi pridobljenih rezultatov lahko sklepamo, da členjenost v primeru obravnavane stavbe vpliva na spremembo toplotnega polja v stavbnem ovoju ter s tem na toplotni tok in toplotne izgube stavbe. Najmanjši toplotni tok teče skozi idealiziran profil. Razgibanost stavbnega ovoja vpliva na povečanje toplotnega toka skozi dele stavbe, kjer je stena zamaknjena v notranjost ali pa se medetažna plošča skozi steno nadaljuje v zunanjost. V takih primerih se nam lokalno poveča toplotna prehodnost, kar posledično vpliva na zmanjšanje energetske učinkovitosti.
