Vpliv toplotnih mostov na porabo energije za ogrevanje na primeru osnovne šole : diplomska naloga

Megušar, Primož (author), Košir, Mitja (mentor), Kristl, Živa (comentor)

Na primeru Osnovne šole Dobrova sem preveril, kakšen vpliv imajo dejanski toplotni mostovi na porabo energije za ogrevanje. Iz načrtov stavbe sem evidentiral vse toplotne mostove, kateri vplivajo na porabo energije. Tem toplotnim mostovom sem nato v standardu SIST EN ISO 14683 poiskal ustrezne približke. Nato sem s programom TOST izvedel tri simulacije. V prvem primeru toplotnih mostov nisem upošteval. V drugem primeru sem toplotne mostove upošteval na poenostavljen način, v zadnjem primeru pa sem jih upošteval po standardu SIST EN ISO 14683. Rezultate za vse tri primere sem nato primerjal med seboj. Na koncu sem podal še nekatere ukrepe, kako bi lahko porabo energije zmanjšali. Rezultati so pokazali, da je poraba energije zaradi toplotnih mostov ki sem jih upošteval po standardu SIST EN ISO 14683 večja za okoli 20% kot v primeru brez upoštevanja toplotnih mostov, pri primeru poenostavljene metode, pa je poraba večja za slabih 12%.

• Title: The impact of thermal bridges on energy consumption for heating in the case of Primary school

Abstract

In the case of Primary school Dobrova I checked what impact have actual thermal bridges on energy consumption for heating. From the plans of the building, I recorded all thermal bridges, which have affect on energy consumption. In standard SIST EN ISO 14683 I seek appropriate approximations to these thermal bridges. Then I made three simulations with the program TOST. In the first case I did not take thermal bridges into account. In the second case, I have taken them into account in a simplified manner and in the last case, I have taken them into account according to the SIST EN ISO 14683. Then I compared the results for all three cases with each other. Finally I made some steps how to reduce energy consumption. The results showed that the energy consumption due to thermal bridges increased by about 20%, comparing to SIST EN ISO 14683, regarding the case without taking them into account. In the case of a simplified method, the consumption increased by nearly 12%.
