Energetska bilanca pred in po delni obnovi toplotnega ovoja večstanovanjske stavbe : diplomska naloga

Rot, Maruša (avtor), Kunič, Roman (mentor), Pajek, Luka (komentor)

V diplomskem delu je bila izračunana energetska bilanca večstanovanjske stavbe s petimi ločenimi stanovanjskimi enotami v Velenju. Računska energetska bilanca je bila narejena za stanje pred obnovo toplotnega ovoja stavbe, za dejansko stanje po izvedeni obnovi toplotnega ovoja stavbe ter za dva primera možnih dodatnih izboljšav trenutnega stanja. Toplotni ovoj stavbe se je v realnosti obnovil le deloma in sicer na delu, ki meji na štiri od petih posameznih enot. Za vse računske primere je bila izračunana potrebna toplota za ogrevanje. Ti rezultati so bili primerjani s podatki o merjeni dejanski porabi toplote za ogrevanje, ki so bili pridobljeni za obdobje treh let pred in leto dni po obnovi toplotnega ovoja stavbe. Izračun potrebne toplote za ogrevanje je bil narejen v skladu z metodologijo, ki jo narekuje zakonodaja na področju energetske učinkovitosti stavb. V diplomskem delu je bil zato predstavljen Pravilnik o učinkoviti rabi energije v stavbah (PURES 2010). Primerjava dejanskih in računskih porab toplote za ogrevanje je pokazala manjša odstopanja, do česar je najverjetneje prišlo zaradi nenatančnih vhodnih podatkov kot so prezračevanje, toplotna prehodnost oken in vrat, prehod celotnega sončnega sevanja skozi okna, notranji dobitki in ostali podatki, ki smo jih vnesli na podlagi inženirske ocene, saj točnih podatkov ni bilo na razpolago. Kljub vsemu so bili končni rezultati primerljivi, z odstopanjem največ 22%.

• Naslov: Energy balance before and after partial renovation of residential building's thermal envelope

Izvleček

In this thesis, the energy balance of residential building with five individual units in Velenje, was calculated. The energy balance was calculated for the situation before the renovation of building's heat envelope, for the actual situation after the completion of the reconstruction of bulding's heat envelope and for the two examples of possible additional improvements of the current situation. In reality, the building's heat envelope was only partly renovated, covering the four of the five individual units. For all numerical examples, the heat required for heating was calculated. These results were compared with data on actual consumption of heat, which has been obtained for a period of three years before and one year after the renovation of building's envelope. Calculation of the necessary heat for heating was made in accordance with the methodology dictated by legal rules in the field of energy efficiency in buildings. Policy on efficient use of energy in buldings (PURES 2010) was therefore presented in the thesis. Comparison of actual and calculated heat consumption has shown minor variations which are most likely due to imprecise inputs such as ventilation, thermal transmittance of windows and doors, passage of the solar radiation through windows, internal gains and other data entered, which was based on engineering estimates, because the exact values were not available. Nevertheless, the final results were comparable.
