Application of glass in materialization of geometrically complex forms of architectural building envelopes.

Sve veća zastupljenost arhitektonskih objekata kompleksnih formi, primena zakrivljenog stakla, stakla kao konstruktivnog materijala, kao i zahtevi za većom transparentnošću omotača, navode na potrebu za kompleksnom analizom elemenata staklenog omotača geometrijski kompleksnih formi, posebno zakrivljenog stakla...Increasing the representation of architectural structures of free forms, the use of curved glass, glass as a construction material, as well as the requirements for greater transparency of the building envelope, indicate to the need for a complex analysis of elements in the glass envelope of geometrically complex form, especially curved glass..

Facility management in serbia - State of the art and perspectives

Trying to estimate perspectives of Facility Management development in Serbia, the authors are looking for rare cases and initiations of Facility Management in practice, considering recent experiences from the countries in the CEE (Central and Eastern Europe) region such as Hungary, Croatia and other European countries in transition. In a milieu of a recovering economy, privatization in progress, a dynamic real estate market and an expansion of foreign investments, development of FM is regarded as a field with a significant perspective. The presence of developed FM concepts in European countries can be a chance for Serbia to start developing its own FM strategy based on the best regional experiences

Value Perspective of Project Stakeholders

When starting a construction project, one assumes, mostly through experience, what is the value the project will bring to investors, consultants, contractors and other stakeholders. However, the value of the project greatly depends on the perspective of the observer and which stakeholder is considering it. So, how is value perceived on the construction project? The purpose of this research is to obtain construction project value parameters utilizing the Delphi technique

Social Housing in Serbia: Dual Approach

Examining Serbian housing policy in the past two decades which has been radically transfered from the communist version of "welfare state" to the neoliberal concept of housing market, this paper firstly identifies major subjects and activities in the field of social housing and systematizes kinds of action related to these activities. Sudden state’s withdrawal from the housing matter, followed by the lack of land regulations and permanent economic crisis, caused almost unsolvable problem of adequate provision of housing for the most of the population in Serbia. The initial course, performed through privatisation of 98 % of public housing stock at the beginning of the last decade of the 20th century, took place apart from the few other housing policy initiatives and processes that were unconformably to each other. The state successively abandoned introduction of housing policy, untill it almost ran short of its institutional and active capacities that had been developing by decades in communism. Until 2004 housing policy was trying to achieve short-dated political aims, but since then, the need for introducton of new systematic housing solutions, including social housing above all, emerged. Serbian government began to act in two separate ways, although without yet astablished long-term national housing policy: First was to try to support, financially and legislatively, production of affordable housing, so called "cheap flats" for subsidized sale; and the other was to try to establish public rented housing, but this time based on economic sustainability instead of general social equity proclaimed in communism. Several projects of "cheap flats" for subsidized sale have been developed, while some of them are stlill under construction, or in the planing stage. On the other side, the initial impulse for public rented housing foundation in Serbia was the 15 milion euros pilot project – Settlement and Integration of Refugees Programme (SIRP 2003-2008.) – financed by the Italian government, that was realized in seven Serbian municipalities. Thus, first non-profit Public Housing Agencies in Serbia were established, and new public housing stock was built and inhabited. Considering serbian social housing policy in general and highlighting some of their characteristics related to several projects, this study focuses on both of these two recognized courses by analisys and critic review of achieved results

Complexity of Curved Glass Structures

Despite the increasing number of research on the architectural structures of curvilinear forms and technological and practical improvement of the glass production observed over recent years, there is still a lack of comprehensive codes and standards, recommendations and experience data linked to real-life curved glass structures applications regarding design, manufacture, use, performance and economy. However, more and more complex buildings and structures with the large areas of glass envelope geometrically complex shape are built every year. The aim of the presented research is to collect data on the existing design philosophy on curved glass structure cases. The investigation includes a survey about how architects and engineers deal with different design aspects of curved glass structures with a special focus on the design and construction process, glass types and structural and fixing systems. The current paper gives a brief overview of the survey findings

Economic aspect of solar thermal collectors integration into facade of multifamily residential building

The subject of this research is the Life cycle costs analysis of the building in order to assess the economic efficiency and cost‐effectiveness of investments in various variants of application of active solar systems in aim to achieve a reduction of energy consumption and environmental pollution. Different variants of solar thermal collector’s application to the existing prefabricated residential building in the settlement Konjarnik in Belgrade, Serbia, are considered from the economic point of view. Cost‐effectiveness and feasibility of various scenarios of energy optimization achieved by application of solar thermal collectors into the building envelope are evaluated on the basis of final energy consumption (within the EU‐ISO standards). The methodological approach involves the analysis of the costs of energy consumption for sanitary hot water preparation, financial analysis of costs and cost savings throughout the lifecycle of the existing building in case of application of solar thermal collectors’ on the building envelope, as well as a comparative analysis of obtained results. Criteria for the economic analysis include the amount of investment, energy costs and life‐cycle costs of the building. According to the adopted criteria, the most suitable models are selected. This methodological approach is generally applicable in the analysis of investments in improvement of building energy performances, while possible technical solutions and the resulting economic benefits must be carefully considered

Integration of solar thermal collectors into the building envelope of the multifamily housing building in Belgrade

Application of solar thermal collectors as one of the modern architectural concepts, which are based on reduction of energy consumption in buildings and the use of solar energy as a renewable energy source, give the new and significant role to the roofs and facades that become multifunctional structures. The purpose of this paper is to show different design solutions and benefits of integration of solar thermal collectors into the envelope of multifamily housing building in Konjarnik settlement, Belgrade. Considering complexity of integration of active solar systems, the following aspects of integration of solar thermal collectors are discussed: energy, architectural and ecological aspects. Hypothetical models of integration of solar thermal collectors into the existing building envelope are created in order to reduce energy demands for water heating, and thus reduce CO2 emissions. ...........solar thermal collector integration in terms of position and slope, evaluation of the reduction of energy consumption for water heating and thus CO2 emissions for different models and their combinations, and comparison of the results (models)

Digital and Architecture: Still Not a Perfect Match

The application of digital technologies in the architectural design has long history of high promises about advances that computers will bring to the practice and relatively low inclusion of the technology in the every day practice. Today, when it is impossible to find architectural bureau without the computers it appears that digital technologies plays irreplaceable part in the architectural design. Contrary to that picture, architects rarely use digital technologies to conceive and develop their concepts. Instead they use computer applications to solve specialized problems, and often outsource professional services to perform that task. The result is that development of computer applications for architectural design is targeted toward digital professional services. Architects feel that they are loosing their profession because they can not control this level of complexity. The paper explores ways how the architects can re-establish their position it the field. The better understanding of software functionality is needed to prevent overoptimistic expectations form the software tools. The paper explores what kind of digital tools architect has at disposal and how to use them to her/his advantage. This knowledge will enable architects to establish improved communication with professional services and to obtain richer feedback that will enable better design process
