Defining worst-performing buildings in Slovenia based on EPCs
Marjana Šijanec-Zavrl, Henrik Gjerkeš, 2023, published scientific conference contribution

Abstract: The 2021 EC proposal for EPBD recast planned inter alia the harmonization of energy performance certificates (EPCs) across EU and definition of minimum energy performance (MEP) standards to support the renovation of worst-performing buildings. Rescaling of EPCs to a common EU ranking and consequently setting MEP standards is a task for the near future, but current planning of building renovation to meet decarbonization by 2050 may only relay on data in Slovenian EPCs from 2013-2022 data base. The paper presents the analysis of energy related indicators in existing Slovenian EPCs in order to demonstrate that existing EPCs issued in last decade can be used to define 15% of worst-performing buildings prioritized for deep and NZEB renovation, if combined with other indicators, like heat demand.
Keywords: energy performance indicators, decarbonization, energy efficiency, building renovation

Comparison of Effectiveness between Traditional and Digital Marketing in a Selected Company
Veronika Stoilkovska, 2022, undergraduate thesis

Abstract: The thesis contains the differences between traditional and digital marketing, a comparison between the advantages and disadvantages for both marketing methods, types of channels they have, methods of calculating the effectiveness of both methods and research to show how theory can be put into application in the real world, and what kind of results come out. The research is based on data from a selected company, Bolton Adriatic d.o.o., where there are consumer brands from three types of industries: house cleaning brand, food brand, and personal care brand. These brands are introduced by traditional ways of marketing, digital ways of marketing, and both marketing ways. The goal of the research is to show the performance of different channels in the year of 2020. The approach to the research is secondary based. Quantitative data was gathered from archives and analysed further into descriptive representation.
Keywords: Traditional marketing, digital marketing, effectiveness, data, performance, comparison, metrics, key performance indicators, advantages and disadvantages

Cu and Zr surface sites in photocatalytic activity of TiO [sub] 2 nanoparticles : the effect of Zr distribution
Olena Pliekhova, O. L. Pliekhov, Mattia Fanetti, Iztok Arčon, Nataša Novak Tušar, Urška Lavrenčič Štangar, 2019, original scientific article

Abstract: The present work is focused on the role of ZrO2 modification in the performance of CuO modified TiO2. Zirconia loading leads to formation of more resistant photocatalytic layers compared to samples modified with only copper containing species. Surface modification of mixed phase TiO2 with CuO/ZrO2 improves the degradation of Reactive blue 19 dye under simulated solar irradiation. An in-depth investigation of the catalysts showed that in case of CuO/ZrO2 modification, the covering of the TiO2 surface with zirconium containing species prevents morphological and harmful energetic changes induced by copper species formed on the rutile TiO2 phase at a higher copper loading.
Keywords: titanium dioxide, surface modification, XAS analysis, surface acidity, Hammett indicators
