Evropska in slovenska gradbena zakonodaja predvidevata postopno uvajanje dinamične metode, ki temelji na urnih vhodnih podatkih in simulira pogoje delovanja objekta na podlagi 3D-modela. V Sloveniji se poleg novega Pravilnika o učinkoviti rabi energije (PURES-3) uvaja tudi obvezna raba informacijskega modeliranja gradenj (BIM). V študiji smo preizkusili različne metodologije za pripravo in prenos podatkov v BIM okolju ter izvedli izračune z uporabo programske opreme CYPE Thermal, ki temelji na dinamičnem orodju EnergyPlus. Za referenčni objekt smo določili štiri scenarije, ki vključujejo različne posege na ovoju stavbe ter aktivno in pasivno senčenje. Ugotovili smo, da obstajajo pomembna odstopanja med obema metodama, ki se razlikujejo glede na specifične scenarije. Največji vpliv na razlike imata pogostost vhodnih podatkov o temperaturi okolice in solarni dobitki, ki jih dinamična metoda obravnava z večjo natančnostjo. Ta raziskava ponuja pomembne vpoglede v metodologijo izračuna energijske učinkovitosti stavb, kar je ključno za trajnostno prenovo obstoječega stavbnega fonda v Sloveniji.

Title:	Methodology for calculating energy use in existing buildings protected as cultural heritage according to PURES-3
Abstract:	This paper presents a methodology for calculating energy use in existing cultural heritage buildings, comparing static (monthly) and dynamic (hourly) methods. European and Slovenian building legislation is gradually introducing the dynamic method, which simulates actual operating conditions based on a 3D model. In Slovenia, the use of Building Information Modelling (BIM) is also becoming mandatory for better data management in construction processes. We tested different methodologies for data preparation and transfer in a BIM environment and performed calculations using CYPE Thermal software based on the EnergyPlus dynamic tool. We focused on a 1960s reference building, defining four scenarios involving different interventions on the building envelope and active/passive shading. All scenarios were calculated using both monthly and hourly methods. Significant discrepancies were found between the two methods, varying depending on the specific scenarios. The dynamic method treats ambient temperature data and solar gains more accurately and allows better control of shading on transparent parts of the envelope, leading to improved prevention of overheating in summer and optimization of solar gains in winter. This study provides important insights into the methodology for calculating the energy performance of buildings, crucial for the sustainable renovation of the existing building stock in Slovenia.
