Modeliranje trajnostne prenove stavbnega fonda na potresnih območjih : magistrsko delo

Fazarinc, Neja (avtor), Dolšek, Matjaž (mentor)

Velik delež obstoječega stavbnega fonda v Evropi, tudi v Sloveniji, je zastarel in ne izpolnjuje sodobnih zahtev glede potresne varnosti in energetske učinkovitosti. Medtem ko se je v preteklosti poudarjala predvsem energetska neučinkovitost, se danes vse bolj prepoznava, da je potresno tveganje v določenih urbanih območjih Evrope še resnejši problem. V Sloveniji je bila zato sprejeta Resolucija o krepitvi potresne varnosti, nova evropska Direktiva o energetski učinkovitosti stavb pa spodbuja tudi potresno prenovo stavbnega fonda. V tem kontekstu je bil razvit model za načrtovanje trajnostne prenove stavbnega fonda na potresnih območjih, ki omogoča modeliranje prenove z vidika potresne odpornosti in energetske učinkovitosti, ovrednotenje potresnega tveganja za ljudi in okolje ter analizo stroškov in emisij ekvivalenta ogljikovega dioksida. Uporaba modela na stavbnem fondu širšega javnega sektorja v Sloveniji je pokazala, da starejše zidane stavbe predstavljajo največje potresno tveganje, vendar imajo največji potencial za izboljšanje. Zaradi znatnega potresnega tveganja za okolje, ki ga izkazujejo starejše potresno najbolj ranljive stavbe, se je izkazalo, da nadomeščanje teh stavb z novimi stavbami ne predstavlja bistveno večjega bremena za okolje, še posebej če stanje stavbnega fonda analiziramo za daljše obdobje. Utrjevanje obstoječih armiranobetonskih stavb do stopnje predpisane s standardom Evrokod 8 je glede na stroške in doprinos k zmanjšanju tveganja na nivoju obravnavanega stavbnega fonda manj smiselno. Razvit model se lahko še izboljša, saj zaradi upoštevanja nizke stopnje poznavanja stavb temelji na številnih predpostavkah, kar vodi v negotovost rezultatov. V tej fazi raziskave smo vpliv teh negotovosti omilili z relativnim prikazom rezultatov glede na ekvivalenten nov stavbni fond, ki ga je prav tako možno simulirati z modelom.

Izvleček

A significant portion of the existing building stock in Europe, including in Slovenia, is outdated and does not meet modern requirements for seismic safety and energy efficiency. While energy inefficiency was primarily emphasized in the past, today it is increasingly recognized that seismic risk in certain urban areas of Europe is an even more serious problem. In Slovenia, a Resolution on Strengthening Seismic Safety was therefore adopted, and the new European Directive on the Energy Performance of Buildings also encourages the seismic renovation of the building stock. In this context, a model was developed for design of the sustainable renovation of building stock in seismic areas, which enables the modelling of renovations from the perspective of seismic resistance and energy efficiency, the assessment of seismic risk to people and the environment, as well as the analysis of costs and carbon dioxide equivalent emissions. The application of the model to building stock in the broader public sector in Slovenia showed that older masonry buildings present the greatest seismic risk but have the highest potential for improvement. Due to the significant seismic risk posed by older, seismically most vulnerable buildings, it was found that replacing these buildings with new ones does not represent a significantly greater environmental burden, especially when the state of the building stock is analyzed over a longer period. Strengthening existing reinforced concrete buildings to the level prescribed by Eurocode 8 is, in terms of costs and contribution to risk reduction at the level of the considered building stock, less feasible. The developed model can be further improved, as it is based on numerous assumptions due to the low level of building knowledge, leading to uncertainty in the results. At this stage of the research, we mitigated the impact of these uncertainties by relatively presenting the results relative to those of an equivalent new building stock, which can also be simulated by the model.
