16. Whole-life carbon emissions benchmarks for buildings in SloveniaMarjana Šijanec-Zavrl, Henrik Gjerkeš, 2021, kratki znanstveni prispevek Opis: According to the European Green Deal decarbonisation of EU building stock is needed on the way to turning EU into the first climate neutral continent by 2050. Directive (2010/31/EU) EPBD led to significant reduction of operational energy in new buildings and renovation. By energy efficiency first principle and by increasing renewable energy sources it contributed to reduction of primary energy and operational CO2 emissions. But the orientation towards lifecycle thinking and circularity in the building sector revealed the need to tackle the whole-life carbon emissions, where the operational and embodied carbon contribute significantly. In the absence of benchmarks for embodied carbon emissions in this contribution the operational and embodied carbon indicators from recent studies are compared with the available corresponding data in Slovenian energy performance certificates.

18. Bottom-up modelling of continuous renovation and energy balance of existing building stock: case study KočevjeMarjana Šijanec Zavrl, Gašper Stegnar, Andraž Rakušček, Henrik Gjerkeš, 2016, objavljeni znanstveni prispevek na konferenci Opis: A dynamic bottom-up model of the building stock is developed and implemented in a case study of Kočevje urban region. In the model, national register of real estate is cross-linked to data from other registers, e.g. the energy performance certificates (EPC) and the subsidized energy renovation measures. Regular updates of the data in registers enable continual improvement of the model. Therenovation potential is determined with respect to the age of building components after the last renovation, while the energy performance of the building stock is based either on the EPC for a
particular building if available or on the energy indicators of corresponding building type from IEE EPISCOPE building typology and IEE RePublic_ZEB. Thus, the bottom-up model of the building stock (BuilS) enable a profound overview of the total heat demand, final energy use and CO2 emissions of the entire stock.
In the case study Kočevje, various strategies for improving the buildings towards more sustainable ones are presented with projections to 2030. The strategies, reference and intensive renovation scenario, are compared with more ambitious strategy that the municipality is looking towards in the frame of Covenant of Mayors commitment. The bottom-up model was validated against the metered energy use of buildings connected to district heating. In the case study the model shows how the implementation of various strategies lead to different impacts and how the ambitious municipal plans are going to produce independence from fossil fuels by fostering the use of wood biomass as a locally
available sustainable energy supply. The Kočevje case study analysis demonstrates, at the local level how a concept of increasing renewable energy sources utilisation and building energy efficiency stimulated by progressive measures can respond to low carbon society and sustainable energy selfsupply challenges.

19. COST AND ENERGY EFFICIENT MODERNIZATION OF SCHOOL BUILDINGS IN UKRAINETetiana Rapina, Marjana Šijanec Zavrl, Henrik Gjerkeš, 2016, kratki znanstveni prispevek Opis: Improvement of the energy efficiency of existing buildings in EU has great potential in the efforts to reduce energy consumption, which is with no doubt relevant issue also for Ukraine. In this article the importance of public building stock modernization was analysed with special focus on school buildings. The optimal cost methodology was used to evaluate not only the economic, but also environmental as well as social effects of school building stock modernization. In searching for the optimal level of energy-efficient modernization of school buildings in Ukraine, the European and Slovenian experiences were used. It is demonstrated that the sustainable reconstruction with the nearly-Zero Energy Building (nZEB) guidelines, as defined in EU regulations, is feasible with good results and can be recommended also for reconstruction of school buildings in Ukraine.

20. Spremljanje delovanja napredno načrtovane skoraj nič-energijske večstanovanjske stavbeGašper Stegnar, Miha Mirtič, Henrik Gjerkeš, Marjana Šijanec Zavrl, 2016, objavljeni znanstveni prispevek na konferenci Opis: Učinkovita raba energije in intenzivnejše izkoriščanje obnovljivih virov energije tudi v stanovanjskem sektorju zahteva sodobne pristope k naprednemu načrtovanju stavb ob hkratni skrbi za ustrezno bivalno ugodje v njih. Nacionalna merila za skoraj nič-energijske stavbe (sNES), ki bodo postala obvezna l. 2020, smo uporabili kot izhodišče za načrtovanje Eko srebrne hiše, večstanovanjske stavbe s 128 stanovanji, ki je bila kot FP7 EE-Highrise demonstracijski projekt l. 2015 zgrajena v Ljubljani. Načrtovanje in gradnja sta potekala z naprednimi orodji za dinamično simulacijo na urni osnovi z realnimi robnimi pogoji, s sprotnim spremljanjem kakovosti, kontrolo zrakotesnosti, spremljanjem rabe energije in parametrov bivalnega ugodja. Primerjava projektiranih in izmerjenih ključnih parametrov v izbranih naseljenih in še nenaseljenih stanovanjih pokaže učinkovitost naprednih orodij za načrtovanje stavb, pri čemer podrobnejša analiza izlušči tudi vzroke za nekatera odstopanja.
