Educational buildings are buildings with special social importance, and their energy consumption requires particular attention. Since the majority of educational buildings in Serbia were built between 1950 and 1990, with concrete frame, brick walls and poor thermal insulation, it can be concluded that these buildings have relatively high potential...

The service sector remains the only economic sector that has recorded an increase (3.8%) in energy consumption during the last decade, and it is projected to grow more than 50% in the following decades. Among the public buildings, educational are especially important since they have high abundance, great retrofit potential in terms of energy saving...

Preschool buildings are among the biggest water consumers in the public buildings sector, which efficient management of water consumption could make considerable savings in city budgets. The aim of this study was twofold: 1) to assess prognostic performances of 21 parameters that influence the water consumption and 2) to assess performances of two...

To provide a warm place for the most vulnerable citizens during the 2022/2023 energy crisis, some municipalities have set up public halls as warming shelters. Thus, the present study analyzes the energy performance of a gymnasium in Southeastern Europe that is repurposed to be used as public warming hall. The study conducted 15 EnergyPlus simulatio...

Electrification of passenger cars is necessity in the transition towards a net zero emission economy. Electric vehicles (EVs) are widely accepted in many developed countries worldwide. According to the 2022 Global EV Outlook by the IEA, there has been an exponential growth in sale of EVs in recent years, but almost all of these vehicles are concent...

Sewage sludge, a by-product of wastewater treatment, is garnering increasing attention in the pursuit of closed-loop economy practices due to its highly beneficial fertilizing properties. However, like any technique, using sewage sludge as fertilizer has potential and limitations. Heavy metals within sewage sludge are a primary limitation curtailin...

In this paper, a numerical analysis (using EnergyPlus software) of the ground source heat pump for heating and cooling in a three-story residential building located in Kragujevac was performed. The ground source heat pump is connected to geothermal vertical probes on the primary side, while on the secondary side, it is connected to floor panel heat...

The way citizens perceive air quality has a huge impact on the public's willingness to contribute agendas that promote a sustainable future. Consequently, the scientific community wonders do the sudden and short-term shifts in air quality (such as one caused by the COVID-19 pandemic) have the potential to induce long-term changes in community behav...

This study investigates the potential of contemporary Earth-Sheltered Buildings to contribute to sustainable societies by achieving Plus Energy Building status during the heating season. The buildings analyzed are intended to house a four-member family (102.5 m 2). The house is equipped with a Ground Source Heat Pump, Geothermal Vertical Probes, Fl...

One of the most important parameters describing a combustible mixture is the laminar burning velocity. The determination of this value forms the basis for the calculation of backflow parameters, the flame cone angle in burners and the turbulent burning velocity. It is also an indispensable parameter in flame stabilization and quenching studies. In...

The current flat-plate solar collectors perform best when their absorbers rotate around their axis. However, with their concentrators, reflectors, and tracking mechanisms, they take up a lot of space and are thus commercially speaking, not the best solutions. This paper proposes a novel solar collector design which employs the (relative) rotation o...

Imposed measures for the protection of public health and prevention of the uncontrolled spread of COVID-19 disease affected before established community traveling patterns. One of the questions scientific community consequently wonders consider the potentials of the occurred circumstances to leave permanent change to community traveling behavior. W...

Considering the relatively high share of households in global final energy and water consumption, washing machines are home appliances with a significant potential for electricity and water saving. The potential depends on the energy rating of a washing machine and the consumption habits of consumers in a household. Therefore, a survey was conducte...

To improve solar collector (SC) efficiency, a variety of designs and materials have been introduced into production practice. Studies describing SC specifics, therefore, are particularly valuable to the scientific community as they contribute to the overall body of knowledge and constant improvement the in the scientific field. In that regard, the...

The pandemic of the COVID-19 virus disease has resulted in significant changes in everyday life. As a result, two-thirds of the urban population has been forced to alter previously established travel habits. With this in mind, the international scientific community wonders if the newly formed travel habits could be maintained after the pandemic is...

More and more attention in sewage sludge management is being devoted to its environmental utilization. This approach is justified both from economic and environmental points of view. However, as with any method, there are certain possibilities and limitations. The goal of the natural utilization of sewage sludge is to recover the valuable agronomic...

Air pollution has a significant impact on citizens’ well-being and overall life quality. In this regard, regular air quality monitoring aims to keep pollution levels within prescribed limits and to identify the factors (winds, traffic, seasons, ambient temperature, air humidity, and so on) that influence pollution levels. To carry out a preliminary...

Indoor swimming pools are buildings with relatively complex energy systems and relatively high energy and water consumption. This paper presents a methodological approach to energy auditing of indoor swimming pool buildings based on ISO 50002. It also includes the application of a multi-criteria decision making (MCDM) method for ranking the propose...

Anaerobic codigestion (AcoD) is a proven option to significantly boost biogas production while utilizing existing digesters and infrastructure. Co-digestion of food waste with sewage sludge (SS) is increasingly exploited to raise energy production and make anaerobic digestion more affordable; however, there is a lack of information on appropriate c...

This paper shows the thermal energy audit of the kindergarten "Zeka", located in the territory of the city of Kragujevac, Serbia. Data of the analyzed building, with an emphasis on the heating system, as well as the climate conditions of the location are shown. Analysis of the thermal energy use, done by implementing a software package "URSA-građev...

Final energy consumption in buildings has the highest share in final energy consumption on a global level. Heat has the highest share in final energy consumption in European buildings. Also, public buildings consume more final energy than residential buildings in general. Specific heat consumption is an important parameter that indicates the state...

Zgrade obrazovnih institucija imaju veliki udeo u ukupnom broju zgrada koje pripadaju javnom sektoru i značajan deo energetske potrošnje pripada ovim zgradama. Na teritoriji Grada Kragujevca nalazi se 15 objekata koje posluju u okviru 2 predškolske ustanove, čija je specifična godišnja potrošnja toplotne energije od 79,42 kWh/m2 do 491,52 kWh/m2 (o...

This paper examines the potentials of saving electric energy in school lighting by replacing the existent systems of lighting with more adequate ones which are based on LED technology. Our primary goal is to present the methodology used in this analysis since it can be used to determine potential savings in lighting systems of any public building....
