Namen diplomskega dela je ugotoviti, kateri konstrukcijski sklop strehe je stroškovno najbolj upravičen, glede na življenjsko dobo, uporabljene materiale in energijsko učinkovitost njihove zasnove. Analiza dela temelji na sedmih scenarijih, razvrščenih v tri skupine po podobnosti, ki vključujejo prenovo strehe reprezentativne Slovenske stanovanjske hiše. Analizirani konstrukcijski sklopi izpolnjujejo vse zahteve po Pravilniku o učinkoviti rabi energije v stavbah. Scenariji vključujejo tako minimalne prenove kot tudi scenarije z bolj celovito prenovo in zamenjavo celotne nosilne konstrukcije strehe. Z uporabo t. i. standardnih in nadstandardnih materialov ter raznoliko kvaliteto vgrajenih elementov, so scenariji približek raznolikosti, ki se pojavlja v praksi. Vsak posamezni scenarij je obravnavan preko energijskega modela hiše, izdelanim v programu KI energija, ki so mu dodani podatki o materialih - gradnikih posameznega dela stavbe. V programu OneClickLCA pa so bili na podlagi izračuna energijske učinkovitosti ter ocenjenih investicijskih stroškov analizirani vseživljenjski stroški stavbe za obdobje 40 let. Medsebojna primerjava scenarijev, skozi njihovo življenjsko dobo, je razvidna s časovno odvisne analize stroškov. Ugotovljeno je, da se na dolgi rok izplača uporaba t. i. nadstandardnih materialov in kvalitetnih elementov, ter da visoki vhodni stroški, še ne pomenijo višjih stroškov, ob koncu življenjske dobe stavbe. Pridobljeni rezultati raziskave, zaradi upoštevanja faze zamenjave dotrajanih materialov, realistično prikažejo visoka medsebojna razlikovanja in odstopanja. Kljub pridobljenim rezultatom pa je zaključeno, da je najoptimalnejši scenarij odvisen od namembnosti nepremičnine in finančnih zmožnosti njenega investitorja.

A cost-optimal approach to the energy renovation of a typical pitched roof |
Sekundarni povzetek: |
The purpose of this thesis is to determine which structural assembly of the roof is the most cost-effective, given the service life, materials used and energy efficiency of their design. The analysis is based on seven scenarios, divided into three groups according to similarity, which include the renovation of the roof of a representative Slovenian residential house. The analyzed construction assemblies meet all the requirements of the Regulations on the efficient use of energy in buildings. Scenarios include both minimal renovations as well as scenarios with a more comprehensive renovation and replacement of the entire load-bearing structure of the roof. Using so-called standard and above-standard materials and the diverse quality of the built-in elements, the scenarios are an approximation of the diversity that occurs in practice. Each individual scenario is considered through the energy model of the house, made in the KI energy program, to which data on the materials - building blocks of each part of the building were added. In the OneClickLCA program, the life costs of the building for a period of 40 years were analyzed on the basis of the calculation of energy efficiency and estimated investment costs. The mutual comparison of scenarios, through their lifetime, is evident from the time-dependent cost analysis. It has been established that the use of so-called above-standard materials and quality elements pays off in the long run, and that high entrance costs do not mean higher costs at the end of the building's lifespan. The obtained research results, due to the consideration of the phase of replacement of worn-out materials, realistically show high mutual differences and deviations. Despite the obtained results, it is concluded that the best-case scenario depends on the purpose of the property and the financial capabilities of its investor. |
