20.500.12556/RUL-180914 The effect of surrounding topography on calculated solar gains in buildings using dynamic building energy modeling (BEM) This paper presents a methodology for integrating terrain shadows of micro-locations into building energy modeling (BEM) for topographically diverse regions. Dynamic energy simulations rely on high-resolution weather data sourced from reference locations that cover a climate zone. As soon as the micro-location of the simulated building is away from the weather reference site, topographic shading can trigger deviations. This study developed a three-dimensional reproduction of the micro-location’s surrounding terrain as a simplified ring model based on available horizon height captured from PVGIS. In a radius of 20 km, 4 Slovenian cities from the same climatic zone have been analyzed and compared with a baseline calculation. When comparing solar gains (SG) of chosen micro-locations, a tendency is noticeable—the lower the Sky-view Factor (SVF), the higher the SG deficit. Additional calculations have been conducted for different SVF/aspect ratios and used in a geographical survey. Results show that at least half of the Slovenian land surface which is inhabited by 21% of the population, has characteristics where topography influences calculated Solar Gains (SG). In those areas, the potential SG deficit is distributed from barely perceptible to more than 25% in certain areas. This approach enhances the precision of BEM in topographically varied landscapes and can inform better design and planning decisions. hourly dynamic method solar gains sky-view factor elevated horizon BIM metoda dinamičnega izračuna na uro sončni dobitki faktor pogleda na nebo dvignjeno obzorje BIM true false true Angleški jezik Slovenski jezik Neznano 2026-03-19 11:33:39 2026-03-19 11:33:47 2026-03-22 04:08:01 0000-00-00 00:00:00 2026 0 0 Str. 177-193 0000-00-00 PostprintKoncna NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 2027-02-21 551.52:69(497.4) 10.1007/978-3-032-14019-7_13 270934275 270251779 RAZ_Hausmeister_Alen_2026.pdf RAZ_Hausmeister_Alen_2026.pdf 1 42A6B9EA055517DF3A873712D3931A16 fad87d6b26fc5a2c3e0f770e5cc53144d7afcd41661f0853f40b81fe8b8e96ba aa484e03-2382-11f1-b0ab-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=230882 https://link.springer.com/chapter/10.1007/978-3-032-14019-7_13 0 0b350465-237f-11f1-b0ab-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=230879 Filozofska fakulteta 0 0 0
