Lack of regulation on the energy efficiency in Serbia in terms of the assessment of the impact of thermal bridges
Get PDFAs one of the aspects of sustainable architecture, the energy efficiency of buildings has largely come to life and has found its practical application in modern construction practice. Active action towards the achievement of the adequate energy performance of buildings implies the creation of appropriate regulations, providing basic guidelines for securing energy efficiency in the design and construction of buildings. In that sense, with a dozen years of delay in relation to the introduction of the EPBD, Serbia has adopted its legal regulations regarding energy efficiency in buildings, being in force since 2012. Respecting the basic guidelines of the original directive, the regulations in Serbia were the subject of major changes in relation to the previous ones, making a major shift in the boundaries of the relevant parameters and the basic methodology of calculating the energy performance of buildings. However, in practice, it has been shown that some of the factors that are important for the design and energy behaviour of the buildings have been treated inadequately. This particularly refers to the problem of thermal bridges, whose impact on the overall energy performance of the buildings is too simplified. Consequently, depending on the complexity of the building, the prescribed calculation methodology often yields significantly fewer energy needs than they actually are. By taking the view that the influence of thermal bridges, regardless of their type and character, is treated as an arbitrary magnification of surface transmission loss in the function of magnifying the surface of the thermal envelope, the real impact of both linear and point heat losses is neglected. While the issue of an adequate calculation of linear losses is directly related to the way of designing the building, that is, to the conception of details, the question of the impact of point losses is a consequence of the structure of thermal envelope elements. The paper presents two types of critical cases of thermal bridges: the treatment of linear thermal bridges for which research has shown that their influence can significantly exceed those envisaged by the current rulebook, and the influence of point heat bridges, as seen in the specific case of ventilated façades in which this problem is present
The Capacity of Incompleteness [STRAND 2020]
Get PDFBeginning with the idea that the elusive nature of the ambivalent position, between belonging and not-belonging, is constantly placed outside existing conceptions, overcoming uncertainties that grow into visible changes, this work aims to unlock the potential for a multiple layering of reality. Fragmentation is positioned as a model for interpreting reality and for examining the capacity to measure the ambiguity and incompleteness of architecture in a post-digital world and culture. By destabilizing reality through the virtual, the visual world becomes a vision of autonomous images – a visual experience within its own fragments. Thus, placing the concepts of incompleteness and insufficiency on the same plane, as something that eludes precise definition, we remain grasping for the possible. As a result, they remain in an ambivalent relationship to their totality and the inability to fulfill it. This means that the conceptualization of fragmented forms occurs virtually, depicting their own outline through digital code, thus making variability and unpredictability a design challenge; a task and a problem. The dual nature of all things raises the question of exceeding one’s own reality, taking for one’s object the process itself and the production of new conditions. Always being in-between, insufficiency paradoxically becomes its own goal, one only possible if focus shifts to the process of creation or its essential unattainability
SAJ : Serbian architectural journal [Size: scale and proportion]
No full textScale and proportion in art and architecture are both concerned
with size: while scale refers to the size of an object in relationship to another
object (relationship of parts of an image to the image as a whole, or to something
in the world outside of the image), proportion refers to the relative size of parts
of a whole (proportion refers to the relationship of parts of a body or form
to one another and of the parts to the whole).Throughout the history of art,
many artworks represent what was considered as an ideal based on the ancient
classical Greek model and therefore serve as an illustration of both scale and
proportion in art..

The Places of (Non)remembrance - the Use of Digital Technologies in Creating the Places of Collective Memory
No full textThe topic of the paper is related to the processes of promoting the cultural heritage of Belgrade by creating a system of interactive places of remembrance. By identifying the relevant and the forgot- ten landmarks of Belgrade, the research aims to revive the stories of the places that played a role in the cultural development of the city but remain unmarked to this day. In the research, the landmarks are named “Mesta (Ne)Sećanja” – The places of (Non)Remembrance. The paper aims to define the means of creating site-specific virtual memorials that promote the identity of Belgrade, while simultaneously implementing the “Digital City” concept of urban development. The polygon of re- search is divided into two zones of Belgrade city centre, that are most visited by tourists. The focus of the work is connecting the 24 historically relevant and unmarked places in Belgrade in a single GIS-based network, which can be accessed by mobile phones or tablets in the specific locations. By connecting the georeferenced places with stories and augmented-reality (AR) models that provide interaction with users in real-time, it is possible to design virtual memorials that create the interfer- ence between the physical public space marked in 24 locations and virtual space at the specific web page or application. The paper relies on the results of an experimental project “Mesta (Ne)Sećanja” (The Places of (Non)Remembrance) conducted in 2017 that tested the implementation of the con- cept at the location of the “Kafana Albanija” historical landmark. The results include the numerical data of user interaction with the digital memorial as well as the guidelines for the physical sign of the memorial in the exact location, based on the tested design variables
Modern facility management concepts in accomplishing urban comfort
Get PDFГенерално посматрано, проблеми у одржавању и коришћењу зграда су универзални, без обзира на степен економске и културне развијености средине у којој се појављују. Jеднако су изражени било да се ради о појединцу, организацији или друштву у целини, јер су објекти и простор око њих значајни ресурси чијом употребом се стварају трошкови. У највећој мери они се могу предвидети, пратити и умањити током животног века објекта, а у складу са савременим функционалним и естетским стандардима. У раду су приказани и анализирани примери који, по мишљењу аутора, најбоље илуструју неопходност примене савременог процеса управљања одржавањем (фасилити менаџмент) у постизању урбаног комфора. Такође, представљено је поређење процеса одржавања и проблема у одржавању описаних у књижевном делу „На Дрини ћуприја“ прослављеног књижевника Иве Андрића са садашњим примерима и проблемима у процесу одржавања зграда и градова у целини.Generally speaking, problems of facility management and building exploitation are universal, regardless of the degree of economic and cultural development of the environment. They arise on an equal scale with individuals, organizations, or the whole society because the facilities and space around them are significant resources whose usage incurs costs. To the largest extent these costs can be calculated in advance, monitored and diminished throughout the facility life-cycle and in accordance with the contemporary functional and aesthetic standards. The paper presents and analyzes the examples which, in author's opinion, best illustrate the necessity to apply the modern facility management in accomplishing urban comfort.
Futhermore, the presented analysis attempts to compare the facility management processes and problems depicted in Ivo Andrić's literary work The Bridge on the Drina with the current examples and problems of facility management and urban maintenance in general

SOHO Vienna - Karaoke & Cocktail bar [42. Salon of Architecture, 2020]
Get PDFSOHO Vienna is located in Millennium City, a shopping and entertainment center in Vienna, Austria. Context, a multitude of programs (cocktail & hookah bar, karaoke, DJ, a stage, a VIP area) and diversity of visitors required various ambiance for different activities and groups of users. In efforts to meet the client`s desires for aesthetics that reflect hookah bar, but also contemporary nightlife style, the backbone of the concept is presented in the “Boho” area created from an assemblage of different patterns and geometry. Blending the variegated programs and styles was challenging. The area of the club is divided into 3 zones /hookah bar, stage & cocktail bar area and “terrace”/. The fluidity of the ambient is achieved by integrating different zones applying characteristic patterns, colors, and materials. All furniture and lighting features were specially designed and custom-made for this club.SOHO Vienna se nalazi u trgovačkom i zabavnom centru „Millennium City” u Beču, Austrija. Kontekst, mnoštvo programa (koktel i nargila bar, karaoke, DJ, bina, VIP prostor) i raznovrsnost posetilaca zahtevali su raznolik ambijent za različite aktivnosti i grupe korisnika. U nastojanju da se zadovolje želje klijenata za estetikom koja odražava nargila bar, ali i savremeni stil noćnog života, okosnica koncepta je predstavljena u „Boho“ prostoru kroz kombinacije različitih dezena i geometrija. Preklapanje raznovrsnih programa i stilova bilo je izazovno. Prostor kluba podeljen je na 3 zone /nargila bar, bina i koktel bar i „terasa“/. Fluidnost ambijenta postiže se integracijom različitih zona primenom karakterističnih šara, boja i materijala. Sav nameštaj i elementi osvetljenja su posebno dizajnirani i izrađeni za ovaj klub.photo credits: Wynn Florant
Dynamic characteristics of CLT panels: Computer modelling and simulations
Get PDFThe fundamental vibration frequency and deflections due to the unit static force of
the cross-laminated timber panels of different heights and spans were calculated. The
calculation of the effective flexural rigidity was performed by the Gamma method. Obtained
values are compared with the values obtained by modeling the construction in the Ansys
software package. Three types of floor panels were analyzed with the same combinations of
layer thicknesses in the cross section, but with different number of layers. The panels are 4, 5
and 6 meters long and 1 meter wide. Based on the results, recommendations have been made in
accordance with current criteria that define the acceptable behavior of lightweight floor
structures in relation to vibrations caused by human action
Urban morphology education in Serbia: Origin, genesis and new tendencies
Get PDFThe origin of urban morphology education goes back to the beginning of the 1970s and a period of radical education reforms at the Faculty of Architecture in Belgrade, where urban environment became the main interdisciplinary topic. The importance of urban form has been since emphasized by planners, architects and politicians in various planning documents, symposiums and as such, became an essential segment of the architectural education. The subjects such as Contemporary architecture and form of the city, Urban environment and urbanization, Urban technic and composition and City environment were an important segment of the education for many years. This tradition was strengthened even more in newest accreditation, due to the individual contribution of academics who introduced new courses such as Urban Morphology and Urban Typology and Morphology. Having in mind recent contribution of researchers to emphasize the challenges of teaching urban morphology, this paper aims to enlighten the origin and genesis of the education of urban morphology at the Faculty of Architecture, University of Belgrade and to shed the light on new tendencies and means of teaching in present days. The paper will analyze syllabus of the courses, teaching methodology and present examples of student’s projects on three different levels and courses: ex cathedra on the bachelor level, practical implementation of theoretical notions in studio design on master level and research-based work on the PhD level
