Abstract
V Sloveniji se energijske analize stavb pretežno izvajajo s pomočjo orodij, ki niso povezljiva s programi za modeliranje stavb. To pomeni, da je treba za isto stavbo izdelati različne modele. Ponavljajoče se vnašanje istih podatkov v različno programsko opremo pomeni daljši čas, potreben za izvedbo, večje stroške, in večjo verjetnost za napake že pri vhodnih podatkih. Informacijsko modeliranje stavb (BIM) uspešno izpodriva načrtovanje v dvodimenzionalnih risarskih programih in hkrati omogoča povezljivost različnih simulacijskih orodij. Za energijske analize smo v magistrski nalogi zbrali program ArchiCAD z dodatkom Ecodesigner STAR, ki omogoča neposredno pretvorbo informacijskega modela v energijski model stavbe znotraj istega programa. V Sloveniji razvita programska oprema za energijske analize za izračun uporablja kvazi-stacionarno metodo. Program ArchiCAD za izračun uporablja bolj natančno urno metodo, vendar izvaja izračune v skladu s standardi, ki niso veljavni v Sloveniji. Na preprostih primerih smo preučili delovanje in uporabo programa, pri čemer smo podali nekaj smernic za modeliranje. Raziskali smo tudi možnosti uporabe geometrijskih in ne-geometrijskih podatkov, ki jih generira program ArchiCAD za izvajanje energijskih simulacij v programskih orodjih, ki upoštevajo predpise, veljavne v Sloveniji. Pretvorbo informacijskega modela stavbe v energijski model smo prikazali na primeru stanovanjskega bloka, na katerem smo po korakih aplicirali ukrepe za izboljšanje energijske učinkovitosti. Prepoznali smo prednosti in opozorili na pomanjkljivosti programa. Ugotovili smo, da je program primeren predvsem za izvajanje hitrih energijskih simulacij v času načrtovanja in za pomoč pri odločanju o smiselnosti ukrepov za izboljšanje energijske učinkovitosti.

Title:Transformation of BIM model to Building Energy Model (BEM)
Abstract:
Building energy analyses in Slovenia are usually performed by tools that do not offer interoperability with building information modelling and other modelling software. This means that several geometrical models need to be re-created for the same building. A repetitive input of geometrical and non-geometrical data into different software packages is a time consuming, costly, and error prone process. Building information modelling (BIM) is replacing traditional two-dimensional drafting and BIM offers interoperability with different simulation tools. In this thesis we explore the energy analysis through the use of ArchiCAD with its plugin Ecodesigner STAR. This program offers seamless transformation from building information model to building energy model within the same software. Building energy analysis software, developed in Slovenia uses a quasi-stationary calculation method. ArchiCAD uses a more precise hourly method, but does not consider standards valid in Slovenia. We used simplified cases to test the software and to develop modelling guidelines. We also studied the possibility of using geometric and non-geometric data generated by ArchiCAD in third party software, that considers calculation methods valid in Slovenia. The transformation from building information model to building energy model is shown in the case of a block of flats. Step-by-step measures were taken to achieve better energy efficiency of the building. During the process strengths and weaknesses of the software were identified. We concluded that the software is most suitable for quick energy analyses in the design stage and as a decision support tool about reasonability of measures taken to improve building energy efficiency.
