Issues of conservation-restoration work on historic buildings / Possibilities of renovating the facade with stucco of the Art Nouveau house Vila Angela

Zelo zanimiv konservatorsko-restavratorski problem predstavlja arhitekturna dediščina. Njena velikost in obsežnost ter vsestranskost problema, ki za primerno obravnavo zahteva interdisciplinarni pristop, predstavlja velik izziv. Prav zaradi izziva, ki ga ohranjanje, konserviranje in restavriranje arhitekturne dediščine predstavlja, sem se v magistrski nalogi odločila raziskati, kako pristopiti k reševanju tovrstnega vprašanja. Osredotočam se predvsem na problem, ki ga predstavlja historični fasadni stavbni ovoj. Nalogo sem razdelila na dva dela. V teoretičnem delu pregledam, kakšne so vzpostavljene smernice za konservatorsko-restavratorsko delo na arhitekturnih objektih. Nato predstavim namen in materialno sestavo fasadnega ovoja in kako različni elementi med seboj sodelujejo. Sledi razlaga nekaterih bolj pogostih poškodb in problematik, ki jih različni destruktivni faktorji propada povzročajo na fasadi. Nato pregledam nekatere konservatorsko-restavratorske postopke, ki jih izvedemo pri obravnavi prej izpostavljenih poškodb. V nalogi se osredotočam predvsem na fasadni ovoj stavbe in v želji, da bi znala preseči vidik svoje stroke, fasadni ovoj pregledam tudi z gradbeno tehničnega vidika. Zanimalo me je stanje gradbeno fizikalnih parametrov zunanjih sten, ki vplivajo na energijsko učinkovitost stavbe. Predvsem me je zanimalo, kako so vidiki energijske prenove in modifikacij združljivi s konservatorsko-restavratorskimi načeli. V drugem delu naloge pa obravnavam problematiko Vile Angele, secesijske vile s Šišenske ceste 78 v Ljubljani. Fasada objekta je v zelo slabem stanju in bo v kratkem potrebovala prenovo. Praktični del naloge sledi zasnovi konservatorsko-restavratorskega načrta za fasado omenjenega arhitekturnega dela, prav tako pa v praksi obravnava v teoretičnem delu predstavljene teme.Architectural heritage presents itself as an interesting conservation-restoration problem. Its versatility and sheer size of potential problems demand an interdisciplinary approach and is therefore quite a challenge. To take on the challenge of preservation, conservation and restoration of architectural object, I have decided to research this topic more thoroughly in my master thesis. In focus of the thesis there is a façade of an existing historic architecture. The thesis is divided in two parts. The first part covers topics on more theoretical level. I did a research on basic guidelines that show set standards for conservation-restoration work on architectural work. Next, basic structural and material composition of an historic building envelope is presented. The explanation and interpretation of the most common expected damage found on historic facades follows. There is also presented an overview of some conservation-restoration procedures, which can serve as a guidance during restoration of previously listed damage. For optimal results when doing the architectural conservation-restoration work in an interdisciplinary team of experts, it is very important to have some level of understanding of all different areas of participating expertise. That led me to expand my research in more technical and construction area. I was especially interested in energy efficiency performance of historic building envelope and how are energy efficiency upgrading measures of historic facades compatible with conservation-restoration principles. In the second part I use knowledge from theoretical part and expand it to more practical case of Vila Angela, secession villa from Ljubljana. The façade of the villa is in a very poor condition and is in need of restoration. Practical part of the thesis follows the scheme of a conservation-restoration plan for the façade of the Vila Angela
