AB  - Construction, one of the largest global economic sectors, has been severely challenged by the economic uncertainties brought on by COVID-19. Since 2020, pandemic-related disruptions and remedial measures have made its historically low performance even more difficult. As a result, recent research mainly addressed these negative consequences on the construction sector. In contrast, this paper aims to identify mitigation strategies recognised as good practices on construction projects in Serbia, in addition to detecting disruptions and quantifying their effects on cost and time overruns. A particular emphasis is given to how the pandemic hastened digital transition and encouraged the adoption of modern project management practices. The research was carried out through a survey of two rounds, conducted one year apart, to obtain an in-depth overview. The findings indicated that, although it had an impact on construction projects, the pandemic was not particularly harmful, because of widely used remedial measures and modern project management techniques. However, the pandemic did not modernise project implementation substantially nor significantly increase the use of cutting-edge digital technologies. Nevertheless, it encouraged project managers to think about introducing new approaches in project management, where digitisation is the new normal. The research findings may indicate to academia and practitioners what strategies may assure a project’s implementation even in enormously changed conditions, such as during a pandemic.

AB  - The construction industry consumes up to half of the excavated primary resources and
generates one-third of total waste annually, impacting the environment and society. To
reduce this impact, maintaining the primary resources in some form within the economy
as long as possible is essential. One of the ways to do this would be to recover waste
products and cycle them back into the economy as a secondary resource, either through
reusing or recycling. This implies carefully planned waste recovery strategies based on the
knowledge of the materials embedded in constructions. The solutions that encourage data
transparency and increase the availability of data on this knowledge to all potential
stakeholders across many industries could contribute to creating more effective strategies.
Digital technologies are the primary tool in the development of such solutions. Integrating
Building Information Modelling (BIM) and Geographic Information Systems (GIS) provides
the power to achieve this. The main objective of this paper is to develop and validate a digital
solution that compiles, systematizes and represents the buildings’ material inventory data
at the municipal level. To this end, a three-step methodological framework was introduced:
(1) development of BIMs for the existing building stock; (2) allocation of material inventory
data to BIMs; and (3) integration of a digital solution into 3D GIS. A residential building in
one of the central municipalities of Belgrade, Serbia, was selected as a case study to evaluate
the proposed concept. The BIM model was reconstructed from aerial and terrestrial scans
(Scan-to BIM), and its semantic enrichment with the data on building type, construction
period, type of built-in materials, their service lives and material quantities acquired from
several publicly available sources. When fully implemented at the urban scale level and
validated in the interaction with public administration, NGOs from the housing sector and
end-users, the platform could be a valuable tool which may maximize the circular potential of each material embedded in buildings and help in more effective policymaking and could be used for benchmarking and progress tracking of achieving strategic goals set within
these policies.

AB  - As governments worldwide attempt to develop sustainable waste management strategies, massive amounts of waste have been accumulating. However, developing an effective waste management strategy requires a thorough understanding of waste types and quantites. The existing efforts to identify waste flows in the built environment are unsuitable for countries with non-reliable statistics as they mostly use location-specific parameters such as data on construction, renovation, demolition activity, and generation rates from the literature. The types and quantities of materials embedded are rarely considered. This study aims to fill the identified gap by estimating the quantities of different material types embedded in Serbian residential building stock. It will do so by calculating the volume and weights of building elements and their materials using information from a detailed building stock typology. The results show that the amounts of materials embedded vary significantly from district to district, ranging from 10 in Toplička District to 96.9 million tons in Belgrade. The mineral materials are the highest contributors to the material embedded, implying that future waste management strategies should focus on them. Apart from the formulation of location-specific circular economy and waste management strategies, these results may be useful for planning energy efficiency retrofitting activities, deconstruction and reversible design strategies.

The proposed model observes the optimization process simultaneously through the four most important aspects of energy efficiency: economic aspect, energy consumption, environmental impact and indoor comfort, taking into account factors that may occur in the building environment during its operation, such as inflation and currency depreciation/appreciation. The model introduces dynamic thermal parameters of the wall that reflect a thermal accumulation of the building envelope and its ability to provide thermal comfort in time-varying atmospheric conditions in the building environment.

AB  - Sektor zgradarstva je najveći pojedinačni potrošač energije. Unapređenje energetske efikasnosti u zgradarstvu jedna je od najšire promovisanih mera za smanjenje eksploatacije neobnovljivih izvora energije i ublažavanje klimatskih promena kroz smanjenje emisije ugljen-dioksida. Ultimativni cilj treba da bude povećanje efikasnosti korišćenja energije i usporavanje rasta ukupne proizvedene energije, što zasigurno dovodi do ublažavanja klimatskih promena.Predmet istraživanja u ovoj disertaciji jeste energetska efikasnost u stambenim zgradama u delu koji se odnosi na smanjenje potrebne energije za grejanje. Uže gledano, predmet istraživanja su: (1) metode za proračun i procenu toplotnih gubitaka termičkog omotača zgrade u nestacionarnim uslovima prenosa toplote; i (2) višekriterijumski modeli za izbor i ocenu energetske efikasnosti građevinskih mera kod izgradnje novih ili energetske sanacije postojećih zgrada.Cilj istraživanja je bio da se definiše model koji bi davao podršku projekt menadžeru u procesu donošenja odluke vezane za izbor optimalnog rešenja pri izgradnji novih objekata ili rekonstrukciju postojećih, pri tome sagledavajući investicionu odluku sa više aspekata imajući u vidu i zahteve velikog broja zainteresovanih strana, kako u kratkoročnom tako i u dugoročnom periodu.U cilju ostvarenja postavljenog zadatka prvo je razvijen originalan precizan matematički model koji opisuje fizički proces razmene toplote između objekta i okoline, a koji dalje predstavlja osnov za pouzdan proračun troškova u periodu eksploatacije, definisanje mogućeg termalnog komfora u objektu kao i procenu uticaja objekta na životnu sredinu.S obzirom na postavljene ciljeve istraživanja, u disertaciji su prezentovana dva rezultata: (1) razvijen je novi pristup za određivanje svih relevantnih dinamičkih termičkih veličina koje služe za procenu prenosa toplote kroz građevinske elementenetransparentnog dela fasade i ocenu toplotnog komfora u zgradama i (2) razvijen je višekriterijumski model za optimizaciju izbora građevinskih mera koji u sebi, pored energetskih, finansijskih i ekoloških parametara, sadrži i dinamičke termičke parametre kao kriterijume za ocenu toplotnog komfora u zgradama...
AB  - Building sector is the largest individual energy consumer. Increasing energy efficiency of buildings is one of the most widely promoted measure for reducing exploitation of non-renewable energy sources and mitigating climate changes through carbon dioxide emission reduction. The ultimate goal should be to increase the efficiency of energy use and the slowdown in overall energy produced, which certainly leads to climate change mitigation.The subject of research in this dissertation was energy efficiency in the residential building sector, in particular, the reduction of energy demand for heating. Narrowly seen, the subject of research was: (1) methods for calculating and estimating heat losses through the building’s thermal envelope in non-stationary conditions of heat transfer and (2) multi-criteria decision-making models for evaluating the energy efficiency of building construction measures for new or existing residential buildings.The aim of the research was to define a model that will support a decision-making process that project manager passes when making an optimal decision regarding the construction of new buildings or the refurbishment of old ones, respecting a large number of stakeholder requirements that project manager must deal with and considering many aspects of the investment in the short and long term.The task was to develop an original precise mathematical model describing the physical process of heat exchange between the building and the environment, which further provides the basis for a reliable calculation of the costs related to energy consumption incurred during the exploitation phase, the assessment of the achieved thermal comfort in the building as well as the assessment of the environmental impact of the building.Having in mind the stated research objectives, two resultes have been presented in the dissertation: (1) a novel approach has been developed for the determination of all relevant dynamic thermal caracteristics used to estimate heat transfer through the opaque components of the building envelope in a dynamic regime and the assessment of thermal comfort in the building and (2) a multi-criteria decision-making model has been developed for the selection of optimal construction measures that, in addition to energy, financial and environmental parameters, implies the introduction of dynamic thermal parameters as criteria for assessing thermal comfort in buildings...

Unapređenje energetske efikasnosti u zgradarstvu jedna je od najšire promovisanih mera za smanjenje eksploatacije neobnovljivih izvora energije i ublažavanje klimatskih promena kroz smanjenje emisije ugljen-dioksida. Ultimativni cilj treba da bude povećanje efikasnosti korišćenja energije i usporavanje rasta ukupne proizvedene energije, što zasigurno dovodi do ublažavanja klimatskih promena.Predmet istraživanja u ovoj disertaciji jeste energetska efikasnost u stambenim zgradama u delu koji se odnosi na smanjenje potrebne energije za grejanje. Uže gledano, predmet istraživanja su: (1) metode za proračun i procenu toplotnih gubitaka termičkog omotača zgrade u nestacionarnim uslovima prenosa toplote; i (2) višekriterijumski modeli za izbor i ocenu energetske efikasnosti građevinskih mera kod izgradnje novih ili energetske sanacije postojećih zgrada.Cilj istraživanja je bio da se definiše model koji bi davao podršku projekt menadžeru u procesu donošenja odluke vezane za izbor optimalnog rešenja pri izgradnji novih objekata ili rekonstrukciju postojećih, pri tome sagledavajući investicionu odluku sa više aspekata imajući u vidu i zahteve velikog broja zainteresovanih strana, kako u kratkoročnom tako i u dugoročnom periodu.U cilju ostvarenja postavljenog zadatka prvo je razvijen originalan precizan matematički model koji opisuje fizički proces razmene toplote između objekta i okoline, a koji dalje predstavlja osnov za pouzdan proračun troškova u periodu eksploatacije, definisanje mogućeg termalnog komfora u objektu kao i procenu uticaja objekta na životnu sredinu.S obzirom na postavljene ciljeve istraživanja, u disertaciji su prezentovana dva rezultata: (1) razvijen je novi pristup za određivanje svih relevantnih dinamičkih termičkih veličina koje služe za procenu prenosa toplote kroz građevinske elementenetransparentnog dela fasade i ocenu toplotnog komfora u zgradama i (2) razvijen je višekriterijumski model za optimizaciju izbora građevinskih mera koji u sebi, pored energetskih, finansijskih i ekoloških parametara, sadrži i dinamičke termičke parametre kao kriterijume za ocenu toplotnog komfora u zgradama..., Building sector is the largest individual energy consumer. Increasing energy efficiency of buildings is one of the most widely promoted measure for reducing exploitation of non-renewable energy sources and mitigating climate changes through carbon dioxide emission reduction. The ultimate goal should be to increase the efficiency of energy use and the slowdown in overall energy produced, which certainly leads to climate change mitigation.The subject of research in this dissertation was energy efficiency in the residential building sector, in particular, the reduction of energy demand for heating. Narrowly seen, the subject of research was: (1) methods for calculating and estimating heat losses through the building’s thermal envelope in non-stationary conditions of heat transfer and (2) multi-criteria decision-making models for evaluating the energy efficiency of building construction measures for new or existing residential buildings.The aim of the research was to define a model that will support a decision-making process that project manager passes when making an optimal decision regarding the construction of new buildings or the refurbishment of old ones, respecting a large number of stakeholder requirements that project manager must deal with and considering many aspects of the investment in the short and long term.The task was to develop an original precise mathematical model describing the physical process of heat exchange between the building and the environment, which further provides the basis for a reliable calculation of the costs related to energy consumption incurred during the exploitation phase, the assessment of the achieved thermal comfort in the building as well as the assessment of the environmental impact of the building.Having in mind the stated research objectives, two resultes have been presented in the dissertation: (1) a novel approach has been developed for the determination of all relevant dynamic thermal caracteristics used to estimate heat transfer through the opaque components of the building envelope in a dynamic regime and the assessment of thermal comfort in the building and (2) a multi-criteria decision-making model has been developed for the selection of optimal construction measures that, in addition to energy, financial and environmental parameters, implies the introduction of dynamic thermal parameters as criteria for assessing thermal comfort in buildings...",

AB  - The dynamic thermal characteristics of the components of a building have a primary influence on the energy performance of the building's envelope under real environmental conditions. In this study, a novel approach for estimation of the thermal impulse response (TIR) functions and determination of the dynamic thermal characteristics of a multilayer facade wall with unknown thermal properties, structure, and dimensions is proposed. Unlike existing approaches, such as those presented by Luo et al. (2010) and Fernandes et al. (2015), which are based on the use of known physical parameters and dimensions of the considered structure for determination of the transfer function, the proposed framework is based solely on data from in-situ experimental measurements of surface temperatures and thermal fluxes through the inner and outer wall surfaces in a dynamic regime. Consequently, the estimated TIR functions and dynamic thermal characteristics reflect the actual physical conditions of the considered building wall. The building wall is modelled as a two-input, two-output linear time invariant (LTI) dynamic system where the surface temperatures and fluxes from both sides are used as system inputs and outputs, respectively. The input and output quantities are related by the convolution integrals and TIR functions. The TIR functions are obtained using the measured data and the least square estimator. As the corresponding system of linear equations is ill-posed, the Tikhonov regularization technique with a single parameter is implemented to overcome the numerical difficulties. The optimal regularization parameter is obtained using the L-curve approach. The estimated TIR functions are validated by comparison with the analytical solutions. The dynamic thermal characteristics of the considered building wall with unknown parameters are determined using the Fourier transform (FT) of the estimated TIR functions. The practical applications of the estimated TIR functions related to the energy performance of buildings (EPB) and energy efficiency, along with additional validation, are demonstrated by the evaluation of the dynamic thermal characteristics, cumulative heat losses, heat accumulation, conductive part of thermal transmittance (U-value), and surface heat fluxes, using only the estimated TIR functions and a control set of the experimental data.

Simulation is based on the model which includes temperature dependence of physical parameters of materials, specific heat and thermal conductivity. Analysis of composite structural members comprises determination of a heat flux field which additionally facilitates understanding of region and geometry ofheat flow, thus enhancing fire protection design. Initial temperature distribution is adopted as uniform, according to Eurocode. Fire conditions were according to ISO 834.The FEM computations for different protection scenario and protective materials for partially encased I section - are conducted in ABAQUS. Obtained results can be used in cost optimization of fire protection measures.

AB  - In this paper, physical processes of adsorption and transport of humidity, which has dominant influence on the physical and thermal characteristics of concrete, has been described. The impact of structure of concrete especially pores dimensions and distribution has been explained. The drastic increase in the coefficient of thermal conductivity λ of concrete at increasing relative humidity has been analyzed. An analytic formula for λ, as a function of the concrete density and moisture content in exploitation conditions, starting from light autoclaved aerated to heavy concrete, has been given. The formula is based on experimental values for λ available in the literature. It has been confirmed that the thermal conductivity of all concretes are directly related to density and inversely to porosity and pores diameters.

AB  - In this paper a three dimensional (3D), Computational Fluid Dynamics (CFD) simulation for indoor air flow and heat transfer in a single room was developed. The multi-layer structure building envelop, with expanded polystyrene (EPS) as thermal insulation inside, has been included into simulation and its influence on thermal performances were analysed. The indoor air flow and temperature distribution were analysed for different thicknesses of EPS insulations and were compared to the case without insulation. The commercial software FLUENT has been used in the simulation. The air flow due to natural convection is included into the model through a buoyancy-driven flow. The realizable k- model, based on Reynolds-Averaged Navier-Stokes (RANS) equations, is used for modelling of the turbulence in air flow. The radiator model with thermal flux as input parameter is used for simulation of heating of the room. In order to resolve flow in boundary layer high resolution grid near walls and low-Reynolds number has been used. According to the presented results the thickness of thermal insulation has significant influence on the indoor air flow and the temperature distribution inside the building.

AB  - In this paper a method of determination of transfer function for temperature measured inside and outside residential building in Belgrade is presented. The instantaneous measurements of indoor temperature inside a living room of the second floor flat of the five store building and outdoor temperature at close vicinity of the building facade were made. The external air temperature were also collected from nearby meteorological station few hundred meters apart of the building at the same moments. The measurements have lasted more than three months in period from 22th April till the 2th August. 2014. The data have been collected by data loggers every 5 minutes. Using a digital processing the periodical daily and seasonal variations have been extracted from indoor and outdoor temperature measurements. These variations for indoor and outdoor temperature are considered as excitation and response functions respectively. The periodic outdoor temperature variations could be considered as complex periodic excitation. The Z transformation have been adopted to obtain temperature variations in frequent domain and temperature transfer function for the considered building construction.

AB  - In this paper, based on in situ experimental temperature measurements, the following dynamic thermal parameters of a wall were calculated: decrement factor, time shift of thermal transmittance and areal heat capacities. The outdoor and indoor air temperature of a resident building in Belgrade during the three months from spring to summer of the last year were collected by data loggers. The experimental data were processed using the techniques of filtering and Locally Scatter plot Smoothing (LOESS) method, in order to get frequency and amplitude of daily temperature variations. A solution of the Fourier heat equation for this case, in matrix formulation in frequency space, is given. Matrix's elements of the Fourier equation were used for calculation of the dynamic thermal parameters of the wall.

AB  - Infrastructure projects are usually followed by numerous standard, but also specific risks associated with project cost, schedule, quality, performance, health and safety aspects, environmental aspects, as well as with other, non‐tangible factors. They, if not timely identified, treated and controlled cause that project actual performance significantly varies from planned values. This paper presents results of a conducted infrastructure construction project risks survey for projects settled in Serbia. The survey includes evaluation of major risks in relation to infrastructure project cost and schedule performance and the analysis of usage, necessity and problems with construction Project Risk Management (PRM) practice in Serbia. Risks in the offered risk list were divided into: General Market Risks, Risks in Feasibility and Design Phase and Risk in Construction Phase and evaluated using Probability‐Impact matrix. Based on the results, the proposal is given for the development of an advance planning cost and schedule performance prediction model.
