Završki, Jerneja (author), Cerovšek, Tomo (mentor), Košir, Mitja (comentor)

Diplomska naloga obravnava možnosti uporabe orodij BIM pri načrtovanju objektov v skladu z vidiki trajnostne gradnje in pri energetski prenovi. S tem namenom smo najprej preučili možnosti uporabe BIM in vidike trajnostne gradnje ter opredelili kriterije za vrednotenje trajnostnih stavb po metodi LEED. Pri obravnavi možnih uporab BIM pri trajnostnem gradbeništvu smo se osredotočili predvsem na okoljske vidike v smislu analize orientacije objekta na zemljišču, zadostne osvetljenosti prostorov, energetske učinkovitosti in emisij CO2. V nadaljevanju naloge smo za izbran objekt izdelali informacijski model in izvedli različne analize osončenja in osenčenja, zadostne osvetljenosti, vpliva mikroklime lokacije in rabe energije v stavbi. Program SketchUp smo uporabili za izdelavo poenostavljenega 3D modela stavbe, ki je primeren za uporabo na v idejni zasnovi projekta. Z uporabo vtičnikov smo na njem izvedli analize osenčenja, navidezno pot sonca po nebu ter vidljivost neba. Izdelan model smo uvozili tudi v program Velux Daylight Visualizer, kjer se izvedejo analize osvetljenosti prostorov. V programu ArchiCAD smo naredili informacijski model stavbe, ki bi bil primeren za uporabo v PGD in PZI stopnjah projekta. Tak model vsebuje podatke o sestavah konstrukcijskih sklopov in uporabljenih sistemih ogrevanja, prezračevanja ter hlajenja (HVAC). Uporabili smo ga za izvedbo energetske analize v programu ArhiCAD z vtičnikom Energy Evaluation. Energetska analiza se ponovi tudi v programih Knauf Insulation Energija, TEDI in TOST. Ti programi ne temeljijo na informacijskem modelu stavbe, je pa njihova obravnava značilnosti HVAC sistemov v stavbi bolj podrobna. Zaradi različnih vhodnih podatkov v programih, lahko prihaja do razlik med rezultati. Izvedli smo primerjavo dobljenih rezultatov iz obravnavanih programov.

• Title: BIM for sustainable design and energy efficiency improvements

Abstract

This graduation thesis focuses on the possibilities of BIM uses for sustainable design and energy efficiency improvements. First, we address possible uses of BIM in general, and continue with aspects of sustainable design in-line with LEED rating systems. In this process we predominantly studied environmental aspects, such as building massing studies and building orientation, sufficient daylight, exposure to the sun, energy efficiency and CO2 emissions. For a selected case study we also developed a building information models (BIM) at different levels of details. In the first step we developed a simplified BIM in Sketchup, which was found useful for conceptual design phase to determine the impact on the location and orientation. Using available plugins we did a shadow analysis and determined sun path along with visibility of the sky. The model was also imported into Velux Daylight Visualizer, in which daylight analysis was made. A detailed building information model using ArchiCAD was created. The model contains information about building envelope, including composite structures and building systems - heating, ventilation and air conditioning (HVAC). Based on this building information model a detailed semi dynamic energy analysis was performed using the plugin Energy Evaluation. The energy analysis was also calculated with other software programs that were not directly connected with the model, only relevant data was used, these are: Knauf Insulation Energija, TEDI and TOST. Because input data for each program is different, the results may also vary. Thus, a comparison of results between used programs was made.
