AB  - The majority of studies dealing with the correlation between human body exergy consumption and thermal comfort use adopted, constant values of metabolic rate for appropriate activity level. Taking into account correlations between metabolic rate and the occupant’s exhaled CO2 volumetric flow rate, this study proposes a novel method for the calculation of metabolic rate using measured CO2 concentration in the indoor air. Using measured values of the air and radiant temperature, relative humidity and air velocity, and calculated values of metabolic rate, the human body exergy consumption rate and corresponding Predicted Mean Vote (PMV) are calculated. Moreover, a novel polynomial relation between them is proposed. Results show that metabolic rate values vary in the range of 0.97 to 1.54 met which leads to significantly wider range of PMV and human body exergy consumption rate comparing to the assumed value of 1.2 met for sedentary school activity. According to the obtained relation, the minimal value of the human body exergy consumption rate occurs for PMV = − 0.02. Results of this study imply that treating CO2 concentration as variable does have an impact on the thermal comfort assessment, providing enhanced correlations between thermal comfort and human body exergy consumption rate.

AB  - The paper deals with an analysis of existing thermal
comfort models based on exergy approach and the impact of
models’ input parameters to the calculation results. The aim of
this paper is to present the results of the application of five
different thermal comfort models based on the exergy analysis,
to compare them, and to determine if they coincide with the
results obtained by using Fanger’s model. While models that
are the most commonly used to evaluate and predict thermal
comfort conditions are based on the first law of thermodynamics,
a handful of authors used both the first and the second law
of thermodynamics in order to develop new thermal comfort
models. Even though the optimal comfort conditions according
to these models may not differ by large margin from the optimal
thermal comfort conditions according to Fanger’s model, it is
concluded that justification of using models based on the exergy
analysis to evaluate thermal comfort is very dependent on the
input parameters, which should all be taken into consideration
separately.

AB  - Residential sector is considered one of the largest consumers of primary energy in the world. The main part of total energy consumption in buildings refers to heating. The study presents a thermodynamic sustainability assessment of different energy sources for residential building heating. The paper presents universal methodology, which can be applied to energy and exergy analysis for all types of buildings. Various options of energy sources were studied, namely: coal, natural gas, electricity, district heating, air-water heat pump, biomass and district heating with a cogeneration. Energy and exergy analyses were conducted and appropriate efficiencies were determined. The calculation of an environmental impact factor and exergetic sustainability index for all types of considered energy sources was performed. The results showed that exergy efficiency was very low in all analyzed cases except for biomass, which leads to poor thermodynamic compatibility of energy quality from the supplied side and the energy used for building heating. It was shown that the highest exergy efficiency was in the case of biomass utilization (about 29%), due to the energy used from renewable energy sources. The minimum environmental impact factor (2.48) and maximum exergetic sustainability index (0.403) were found for the case of biomass utilization.

AB  - It is well known that design of a product is a key driver of the success or failure in this field. In industrial design, product design process is not entirely controlled by physical conditions as material properties, the structural strength or production constrains. Besides usability, ergonomics and functionality it is also influenced by many known and unknown factors. One of them is culture, because culture affects the way users respond to the product. And not only the culture of users, but also the designer’s own culture, their aesthetic preferences, emotions and other non-physical aspects. For that reason, any activity of product design must include the knowledge of culture. For understanding the relation between culture, designer, users and the product itself—modern product design has to involve also the concept of sustainability and (especially) the connection between culture and sustainability. In this respect, there are nowadays a lot of talk about the so-called UX (user experience) design, which also be discussed in this article.

AB  - It is sometimes economically unreasonable to develop specific turbines, but rather to use a well-known concept of a pump in the turbine mode - PAT (Pump As Turbine). Inspired by PAT, the scope of this paper covers the assessments of the possibility to use marine propellers as runners for the hydrokinetic turbines. Numerical analyses are conducted for selected propeller geometry with the aim of evaluating its energy characteristics in the turbine regime. The chosen propeller belongs to the conventional, thoroughly experimentally tested, Wageningen B -screw series. The experimental data were used for validation of the numerical results in propeller regimes. Based on the obtained results, the researched non-optimized turbine in its optimum regime achieves a satisfactory power coefficient which is close to the value of other types of contemporary hydrokinetic turbines efficiencies.

AB  - More than one third of the world's primary energy demand refers to residential sector. Heating is considered as one of the main part of the energy consumption in buildings. In this study, a thermodynamic sustainability assessment analysis of different energy sources for heating of residential building, with net floor heated area of 162 m2, for Belgrade weather data, was presented. Five options of energy sources were studied, namely: coal, natural gas, electricity, district heating and air-water heat pump. Energy and exergy analyses were conducted and appropriate efficiencies were determined. Energy and exergy flows in boundaries of the building and in the whole chain from primary to final values were analyzed. The environmental impact factor and exergetic sustainability index were determined for all considered energy sources. The exergy efficiency is very low in all analyzed cases, which further implies poor thermodynamic compatibility of energy quality from the supplied side and the energy used for building heating. It was shown that the highest exergy efficiency is for the case of heat pump utilization (about 6%), due to the energy used from environment. The minimum environmental impact factor (15.37) and maximum exergetic sustainability index (0.065) were found for the case of heat pump utilization.

abstract = "U radu je prikazan matematički model rada solarnog sistema za zagrevanje vode. Analizirani solarni sistem sadrži ravne solarne kolektore, dva akumulaciona rezervoara za vodu, spoljašnji razmenjivač toplote i dopunski izvor energije. Primenjeni model omogućava simulaciju rada i određivanje odgovarajućih energetskih pokazatelja rada sistema i njegovih elemenata za različite lokacije (klimatske uslove), orijentaciju kolektora, termičkih karakteristika komponenata sistema, kao i različitu dinamiku korišćenja tople vode. Rezultati simulacije su prikazani za dane tipične meteorološke godine za Beograd i dnevni profil korišćenja tople vode. Prikazana je analiza energetskih karakteristika sistema. Rezultati dobijeni numeričkom simulacijom su poređeni sa rezultatima dobijenim primenom f-chart metode proračuna., The paper presents a mathematical model of the solar water heating system. The analyzed solar system consists of flat collectors, two water storage tanks, outer heat-exchanger and a source of auxiliary energy. The implemented model enables simulation of system operation and determination of appropriate energy characteristics of the system and its elements for different locations (climatic data), orientations of collectors, thermal characteristics of system components, as well as different dynamics of hot water consumption. Results of the simulation are presented for the days of a typical meteorological year for Belgrade and the daily profile of hot water consumption. The analysis of the energy performances of the system is presented. The results obtained by simulation were compared with the results obtained with the -chart method of calculation.",

AB  - According to the  energy  balance for Republic of Serbia for 2017, the  total final energy  needs for 2017 for Re-public  of  Serbia  are  estimated  as 8429  Mtoe,  with  a  share  of  48% estimated  for  households,  agricultural,  public  and commercial  sectors.  In  the  structure  of  final  energy  consumption  by  fuel  for  2017  in  Serbia,  the  renewable  energy sources are participating with a share of 12% (only geothermal energy and biomass). In order to provide better under-standing of all important aspects of energy usage, beside the quantitative (energetic) analysis, it is necessary to perform also  qualitative  (exergetic)  analysis,  together  with  the  analysis  of  different  fuels  usage  impact  on  environment.  Fuel costs  should  take  into  a  consideration  the  value  of  usable  part,  with  other  words  the  quality  of  their  energy,  namely exergy. The paper presents thermodynamic and economic analysis of different fuels usage, for residential building, with net heated area cca 160 m2, for Belgrade weather data. Results are presented as a comparison between different fuels used for heating and domestic hot water preparation, such as: electricity, natural gas, district heating, coal and renew-able energy sources. The comparison is shown for primary energy consumption, CO2emission, exergy consumption and energy and exergy costs for different fuels.

AB  - The current standards for solar components and systems testing (SRB, EN, ISO, DIN, etc.) imply the determination of the system relevant parameters at the monitored locality.  In this regard, it is necessary to prepare all the input data for the selected location in order to determine the standard values, such as: thermal collector performance, factor changes in incident angle of radiation, heat capacity, pressure values and various quality tests. The parameters collected with appropriate measuring instruments are necessary for defining the state of atmospheric moisture air (temperature, relative humidity), air movement (speed and wind direction), ambient characteristic at given location (clouds, precipitation, etc.) and parameters that describe the energetic potential of the Sun (total, direct and diffusion radiation). А software tool for meteorological data processing (SOLAR) is designed and constructed so that the collected data of experimental measurements can be effectively and easily processed, with the possibility to present the results in a number of ways. The basic software components are subroutines for data filtering (extracting the minimum, maximum and average values in the selected time interval of observation), data processing (calculation of unknown characteristic values that are based on experimentally measured values), and visualization of results (graphical representation results).
