| Popis: | V nalogi je predstavljen proces bioklimatskega načrtovanja enodružinskih montažnih lesenih stavb na treh različnih lokacijah z drugačnimi podnebnimi značilnostmi (Ljubljana, Trbiž in Trst). Cilj je bil prikazati kako stavbe z enakimi izhodiščnimi pogoji, zaradi različne lokacije, zahtevajo drugačne načrtovalske ukrepe. Pri določitvi ustreznosti posameznega ukrepa smo se osredotočili na porabo energije (za ogrevanje in/ali ohlajevanje). Kot orodje za načrtovanje smo uporabili ukrepe pasivno solarne arhitekture, ki temeljijo na selektivni kontroli energetskih dobitkov in izgub. Načrtovanje smo prikazali s tremi stopnjami modeliranja, pri tem smo za analize uporabili programsko orodje EnergyPlus. Na prvi stopnji smo analizirali osnovne pasivne ukrepe, kot so oblika stavbe, orientacija in delež zasteklitve. Analize so pokazale medsebojno primerljivost lokacij, saj smo na prvi stopnji energetske izgube želeli kar se da zmanjšati. Analize oblike in razporeditev transparentnih površin, analiza načina in deleža senčenja ter barva fasade, ki pomenijo drugo in tretjo stopnjo modeliranja so pokazale drugačne rezultate. Stavbe na različnih lokacijah namreč zahtevajo drugačne optimalne načrtovalske ukrepe. Opravili smo še analizo o vplivu dodatne termične mase v stavbi. Zanimala sta nas sprememba neto potrebne energije za delovanje stavbe in temperaturni odziv stavbe v prostem teku. V splošnem je imela dodatna termična masa pozitiven vpliv, vendar učinek ni bil povsod enak. Zaradi želje to tematiko približati splošni javnosti, smo na koncu oblikovali informativno brošuro, ki preprosto predstavi primerne načrtovalske ukrepe v povezavi z lokacijo. Z nalogo smo tako poudarili uporabnost bioklimatskega načrtovanja ter pomembnost povezave med načrtovanjem stavbe, lokacijo (podnebjem) in možnimi energetskimi prihranki. The thesis analyzes bioclimatic design approach in case of residential prefabricated lightweight timber houses on three different locations with different climatic characteristics (Ljubljana, Tarvisio and Trieste). Our goal was to show that climate data determines specific design principles. Adequacy of design principles was specified according to net site energy consumption (cooling and heating energy). Design approach was introduced and accomplished with the aid of passive solar architecture, which uses specific design principles for energy control. The design process was divided into three parts (first model, second model and a house prototype). Model analyses were performed with the help of EnergyPlus software. In the first model we analyzed all the basic design parameters such as building shape, orientation of buildings and windows and ratio of transparent surface area. The results showed similarity between the locations and optimal passive design applications in the context of preventing heat loss. However, in further analyses of window, sunshade and facade color we were able to prove the contrary (second and third modeling faze). Different locations require different design principles. Furthermore, we analyzed how integration of thermal mass in lightweight buildings changes energy consumption values and amplitude of temperature response in thermal zone when building is in free run mode. In general thermal mass has a positive influence on energy consumption in all the three locations, but the effect is not equal. For educational purposes we wanted to create a practical and useful product that presents appropriate design parameters in specific locations. To summarize, with thesis we have shown the applicability of bioclimatic design approach and the connection between building design, location (climate) and potential energy cost reduction. |
