Утицај инфилтрације на енергетске потребе зграде – преглед метода верификације
Get PDFInfiltration has a considerable impact on both, energy efficiency and occupant comfort in buildings. Due to the complexity of the analysis of this phenomenon in buildings, the verification methods are very important for its diagnostics and evaluation. In this paper, the matter of infiltration in buildings is being considered referring to both, calculation models and methods, as well as through current standards and regulations in the EU and Serbia. Different valorization methods are presented and analyzed regarding their characteristics, applicability, and complexity. Finally, preliminary infiltration measurements with a pressurization test, conducted on selected buildings of Belgrade housing stock are presented and compared with values defined by the current regulations in Serbia. Results pointed out current problems and the need for improvements regarding the treatment of infiltration in local regulations and practice.Инфилтрација има значајан утицај у разматрању питања како енергетске ефикасности тако и комфора у објектима. Због сложености анализе овог феномена, методе верификације показале су се као веома важне приликом дијагностиковања и евалуације инфилтрације. У овом раду се питање инфилтрације разматра у односу на моделе и методе прорачуна, као и тренутне стандарде и прописе у ЕУ и Србији. Разматране су различите методе верификације кроз анализу и поређење њихових карактеристика, применљивост и сложеност. Представљена су и прелиминарна мерења инфилтрације одабраних објеката у склопу стамбеног фонда Београда тестом притиска удувавањем која су упоређена са вредностима дефинисаним важећим прописима у Србији. Резултати су указали на тренутне проблеме и потребу унапређења третмана инфилтрације у локалним прописима и пракси
Urban Form and Function
No full textUrban space is social space. According to Henri Lefebvre, every type of society produces a spatiality – physical space itself, a way of organising it and a way of thinking about it. In this sense, spatiality encompasses the physical world, mental world and social construction of space. The production of space occurs through both social practices and material conditions. This means that space and time are contingent upon and shaped by macro‐scale policies and technologies as well as by everyday practices. Structuring of space and time produce specific social patterns and relationships, but it also affects cultural values and economic prospects. Urban form, function and structure are key features in defining urban space as social
Eighty-year review of the evolution of landscape ecology: from a spatial planning perspective
No full textContext
Sustainable spatial development requires the establishment of a balance between rational land use and the protection of nature, ecosystems and biodiversity on various spatial levels and temporal horizons. The integration of landscape ecology and spatial development planning can help overcome the complex problems of managing landscapes and natural resources and increase the chances of reaching sustainable spatial development.
Objectives
The main goal of this research is to provide insight into the development of landscape ecology from the spatial planning perspective.
Methods
A chronological systematization and categorization were made of relevant papers, authors and events that are important for an understanding of the discipline’s development. An analysis of their content and interrelationships in the integral chronological overview enabled the identification of landscape ecology’s developmental periods.
Results
Research resulted in the elaboration of an integral chronological overview of the scholarly and professional communities’ key activities and achievements, making it possible to monitor the development of theory, key developmental concepts and their corresponding methodological procedures, methods and techniques. The overview enabled the identification of (a) types of “arenas” for professional dialogue, (b) key authors and works, (c) relationships among components within the same, but also between different, categories of components of the chronological overview, and on the basis of all this (d) the establishment of developmental periods. Five developmental periods of the discipline have been established: (1) Landscape Ecology Foundation Period 1939–1979, (2) Landscape Ecology Establishment Period 1980–1987, (3) Landscape Ecology Solidification Period 1988–1991, (4) Period of Retrospection and New Articulation 1992–2005, and (5) Period of Stable Development 2006- present.
Conclusions
Research indicated continued development of the theoretical–methodological framework of landscape ecology and its links with spatial planning through the constant reexamination of existing perspectives and the establishment of new ones. The numerous conceptual frameworks selected in the paper unequivocally illustrate a strong conditionality between landscape ecology and spatial planning. However, the systematization of written sources revealed that few papers present a review or perspectives with regard to the link with spatial planning, which is why this research has become an important basis for future research in a form of a curriculum for initial research on the relationship between landscape ecology and spatial planning
Geometrical realisations of the simple permutoassociahedron by Minkowski sums
Get PDFThis paper introduces a family of n-polytopes, P An,c which is a geometrical realisation of simple permutoassociahedra. It has significant importance
serving as a topological proof of Mac Lane’s coherence. Polytopes in this
family are defined as Minkowski sums of certain polytopes such that every
summand produces exactly one truncation of the permutohedron, i.e. yields
to the appropriate facet of the resulting sum. Additionally, it leads to the
correlation between Minkowski sums and truncations, which gives a general
procedure for similar geometrical realisation of a wider class of polytopes
Possibilities for the Improvement of the Access to MEP Systems in Apartment Buildings
Get PDFThis paper offers the possibilities for providing easier access to MEP systems in multi-storey apartment buildings from mass post-war developments, common for ex socialist countries. Insufficiently defined ownership relations and legal regulations in this area are the cause for inadequate access to and maintenance of MEP systems. The aim of the research was to indicate the need for establishing new technical and technological conditions and laws on building and maintenance of MEP in mixed ownership apartment buildings both in new market and in social conditions. The research included the analysis of buildings belonging to typical apartment blocks. Measures and recommendations for the improvement in the design stage as well as interventions in existing buildings and regulations are presented as the research outcome
The Application of Photovoltaic Systems in Sacred Buildings for the Purpose of Electric Power Production: The Case Study of the Cathedral of St. Michael the Archangel in Belgrade
Get PDFIn light of climate changes, technological development and the use of renewable energy
sources are considered very important nowadays, both in newly designed structures and reconstructed
historic buildings, resulting in the reduction in the commercial energy consumption and CO2
environmental emissions. This paper explores the possibilities of improving the energy efficiency of
sacred heritage buildings by utilizing photovoltaic systems. As an exceptionally significant cultural
good, the Cathedral of St. Michael the Archangel in Belgrade shall serve as a case study, with the aim
of examining the methods of mounting photovoltaic (PV) panels, taking into account the fact that the
authenticity and the aesthetic value of this cultural monument must remain intact. A comparative
analysis of the two options for installing PV panels on the southwestern roof of the church was
performed using simulations in PVgis and PVsist V6.84 software, with the aim of establishing the
most efficient option in terms of power generation. The simulation results show that photovoltaic
panels can produce 151,650 kWh (Option 1) and 150,894 kWh (Option 2) per year, while the required
amount of energy is 42,726 kWh. The electricity produced exceeds the electricity requirements for the
decorative lighting of the Cathedral Church, so it can be used for other purposes in the sacred complex.This article belongs to the Special Issue Preventive Conservation and Energy Efficiency of Heritage Building
Strengthening the Social Sustainability of Super-Blocks: Belgrade's Emerging Urban Hubs
Get PDFFocusing on the social aspect of sustainability, this article provides insight into the process of spatial and functional reconsideration of open public spaces in two selected super-blocks in Belgrade, Serbia. Although their spatial typology is similar, one of them was created during the 1960s in New Belgrade, a new administrative center of the city based on the principles of functionalism, while the other one was built during the 1970s, as a part of urban reconstruction conducted in the central areas of Belgrade (Vračar municipality). The beginning of the 21st century has brought new challenges to open public spaces, reflecting the post-transitional changes of the Serbian socio-economic context, as well as the contemporary urban needs of inhabitants. Consequently, both blocks have developed new gathering places for their local communities, although applying two different approaches, spontaneous/informal (New Belgrade) and formal (Vračar). Considering the specificities of both initiatives and the relationship between local communities and the open public spaces of super-blocks, the comparative analysis is conducted in order to identify the occurring social, spatial, and functional modifications, and the achieved level of social sustainability
SAJ : Serbian architectural journal [Drawing in action]
No full textFor years, it has been a great pleasure to watch young creatives
use drawing as a favorite means of expression, from spontaneous
graffiti, sketches and conceptual notes to the realization of graduate projects. In
teaching, from the basic study in the first year of undergraduate studies to the
realization of doctoral studies, drawing is always present as the dominant art
technique in the study of architecture. Various poetics of expression also bring
an inexhaustible source of variations of its use, some of which are presented in
this volume. In the Architecture and Visual Language, an ellective course taught
at the Faculty of Architecture in Belgrade, drawing is cultivated as a basic art
discipline, where works worthy of exhibition in an art gallery are occasionally
created. In this course, students are engaged in examining their relationship to the border field of architecture and art, and the result of the work is always a
realized project..
"Bajloni" brewery in Belgrade - possibilities for protection, revitalization and re-use
No full textIn the last decades, the development of Belgrade has had a negative effect with regard to
the industrial heritage built in the 19th and early 20th century. In order to stop this tendency
and to demonstrate a will to achieve further sustainable development, it is necessary to
redefine the approach to the protection of the Belgrade industrial zones, creating a new one
for urban and spatial planning, taking into account all the specificities, tradition, authenticity
and identity. With all the reconstructions and inadequate changes in the city industrial
zones, particularly along the Sava and Danube banks, the historical cityscape, with its
characteristic morphology and typology, is gradually fading away.
The education process for the students of architecture, the future builders, provides
possibilities to comprehend the problems of the city's industrial heritage protection, its
historical and urban context, its genesis and cultural and architectural values. Furthermore,
it also provides possibilities of comparing different approaches in its presentation and
modern utilization.
This paper will present a search for possibilities of protecting the “Bajloni” Brewery in
Belgrade, its presentation and inclusion in the modern way of life. It was a part of the
master's academic program at the University of Belgrade - Faculty of Architecture. Through a
designing process, the students put an accent on comprehensive investigations of its entire
history: various changes in its structure, from the middle of the 19th century to the present
day. The goal was to define a sustainable solution that would protect all the development
stages of the complex. On the other hand, the idea was to make the complex active and
useful once again and to reintegrate it in its immediate surroundings. Consequently, the
students proposed a number of modern cultural, educational and artistic uses of the
complex, which would be in correlation with its character and significance, thus providing a
way of achieving an active future
