PRIMERJAVA ENERGETSKIH IZRAČUNOV STANOVANJSKE HIŠE Z UPORABO PROGRAMOV PHPP V8 IN PHPP V10

Kos, Urh (avtor), Pušnik, Igor (mentor)

Osrednji namen diplomskega dela je bila analiza in primerjava energetskih izračunov stanovanjske hiše, izvedenih z uporabo dveh različic programskega orodja PHPP (Passive House Planning Package), različic 8 in 10. Cilj raziskave je bil ugotoviti, kako se nova različica programa razlikuje od starejše pri obdelavi enakih vhodnih podatkov, izračunu toplotnih izgub in dobitkov ter vplivu teh razlik na končno energetsko oceno objekta. V teoretičnem delu so predstavljene osnove energetske učinkovitosti stavb, vključno s toplotnimi izgubami, toplotnimi dobitki in standardi energetske učinkovitosti, kot so nizkoenergijske, pasivne in skoraj ničenergijske hiše. Podrobno je opisan tudi programski paket PHPP, njegova struktura, delovanje ter posamezni zavihki, ki omogočajo celovito energetsko analizo objekta. V praktičnem delu je obravnavana stanovanjska hiša v Domžalah, zgrajena leta 1970. Opisan je njen konstrukcijski sistem, toplotni ovoj, gradbeni materiali ter prezračevalni in ogrevalni sistemi. Na podlagi zbranih podatkov je bila v obeh različicah programa izvedena energetska bilanca. Primerjava rezultatov programskih paketov zajema razlike med rezultati energetskih bilanc, njihove utemeljitve na podlagi izračunov ter razlike vnesenih vhodnih podatkov. V zaključku naloge so predstavljeni tudi predlogi za izboljšanje energetske učinkovitosti objekta, kot so dodatna izolacija toplotnega ovoja, izboljšanje zrakotesnosti in vgradnja prezračevalnega sistema z rekuperacijo. Delo potrjuje, da sta si programska paketa PHPP V8 in PHPP V10 podobna do te mere, da so njuni rezultati energetskih bilanc primerljivi, kljub nekaterim prisotnim razlikam.

Izvleček

The main purpose of the thesis was to analyze and compare energy calculations for a residential house performed using two versions of the PHPP (Passive House Planning Package) software tool, versions 8 and 10. The aim of the research was to determine how the new version of the program differs from the older one in processing the same input data, calculating heat losses and gains, and the impact of these differences on the final energy rating of the building. The theoretical part presents the basics of energy efficiency in buildings, including heat losses, heat gains, and energy efficiency standards such as low-energy, passive, and nearly zero-energy houses. The PHPP software package, its structure, operation, and individual tabs that enable a comprehensive energy analysis of a building are also described in detail. The practical part deals with a residential house in Domžale, built in 1970. Its structural system, thermal envelope, building materials, and ventilation and heating systems are described. Based on the collected data, an energy balance was performed in both versions of the program. The comparison of the results of the software packages covers the differences between the results of the energy balances, their justification based on calculations, and the differences in the input data. The conclusion of the thesis also presents proposals for improving the energy efficiency of the building, such as additional insulation of the thermal envelope, improvement of airtightness, and installation of a ventilation system with heat recovery. The thesis confirms that the PHPP V8 and PHPP V10 software packages are similar to the extent that their energy balance results are comparable, despite some differences.
