V sklopu diplomske naloge je bilo izvedeno terensko evidentiranje toplotnih mostov, ki se pojavljajo na realnih stavbah. Pri tem smo si pomagali z IR kamero, ki deluje na principu termografije. V sklopu evidentiranja toplotnih mostov smo izdelali tudi katalog toplotnih mostov na podlagi standarda SIST EN ISO 14683, ki je opremljen z IR posnetki toplotnih mostov iz realnih stavb. V drugem delu naloge pa smo preverili kako vplivajo toplotni mostovi na energetsko bilanco izbrane enodružinske stavbe. Za potrebe teh izračunov smo omenjeno stavbo locirali v Ljubljano. Izračune smo naredili na tri različne načine upoštevanja toplotnih mostov. Prvi način je upoštevanje toplotnih mostov na poenostavljen način, kot to predpisuje tehnična smernica (TSG-01-004-3.1.2). Drugi način je bil z upoštevanjem toplotnih mostov po standardu SIST EN ISO 14683, pri čemer nismo vnesli nobenega toplotnega mostu. Tretji način pa je bil po standardu SIST EN ISO 14683 z vnesenimi vsemi toplotnimi mostovi, ki se pojavljajo na izbrani stavbi. Pri tem smo ugotovili, da način izračuna pomembno vpliva na energetsko bilanco. Izkazalo se je, da so si rezultati, pridobljeni z upoštevanjem enostavne metode iz tehnične smernice (TSG-01-004-3.1.2) in rezultati pridobljeni z metodo po standardu SIST EN ISO 14683 brez vnesenih toplotnih mostov precej blizu, z majhnimi medsebojnimi odstopanji. Če te rezultate primerjamo z rezultati pridobljenimi po metodi iz standarda SIST EN ISO 14683 z upoštevanjem dejanskih toplotnih mostov na stavbi, jasno vidimo, da so odstopanja precej večja.

• Title: Field analysis of thermal bridges with IR camera and assessment of their influence on the building energy consumption

Abstract

The thesis consists of field evaluation of thermal bridges on real buildings with the help of IR camera. For this purpose we made a catalog of thermal bridges which is based on the standard SIST EN ISO 14683 and completed with the IR pictures of realistic thermal bridges. In the second part of the thesis we calculated the influence of thermal bridges on the energy consumption of our chosen building. The chosen building is modern family house located in Ljubljana. Energy consumption was calculated on three different ways regarding thermal bridges. The first calculation was in accordance with Slovenian technical building guide (TSG-01-004-3.1.2). The second calculation was based on the standard SIST EN ISO 14683 with the difference that no thermal bridge was included. The last calculation was basically no different than the second one except that all the thermal bridges that are possible on the building were included. The final result was a conclusion that it is really important which method is used in calculating the buildings energy consumption. First and second calculation showed only a small difference in the results. However results of the third calculation were very different from the first two, supporting our conclusion.
