This paper presents the methodology for the implementation of building typology principles as a tool for the strategic planning of residential building stock energy retrofits on a municipal level in Serbia. Research was conducted under the IEE EPISCOPE (Intelligent Energy Europe EPISCOPE/TABULA project) project with the aim of developing an adequate tool for creating building stock energy retrofit management strategies on a local level. An approach that envisions the diversity and uneven spatial distribution of building stock in smaller scale municipalities and includes statistically relevant sampling of all relevant building types was developed and tested in the pilot project that focused on the city of Vršac. Two options for local typology development were formulated: a top-down approach, which relies on the data from the national typology or other available databases by reducing them to the local level, and a bottom-up approach, which represents a new data gathering and processing method. Both approaches were tested in the pilot project and the results are compared in this paper. From the conclusions of these analyses, a common methodology for the development of local building typologies has been defined. It can be used in the strategic planning of building stock, whether for the purpose of developing local energy action plans (LEAPs) or other purposes internationally.

As 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.

Following the guidance set by the Directive on the energy performance of buildings (recast) (EPBD2), current regulations in Serbia which refer to the issue of energy efficiency and energy certification of buildings provides an opportunity of certification of selected unit of a building, such as a dwelling. This measure was set in order to make it possible for owners or tenants of the building or the building unit to assess and compare its energy performance. From the user?s perspective this measure is very important since, apart from reviewing the quality or the deficiencies of space in which they live, it would be an important parameter of economic evaluation of the apartment in the future. As energy performance of the apartment is not a priori identical to that of the whole building, the paper will analyze and compare these values for different positions in a horizontal and vertical plan of the same apartment within the building. Comparison of the results obtained for individual dwellings and for a building as a whole, will provide insight into the extent to which the disposition and the orientation of the apartment affect its energy performance.

As a side effect of the need for greater energy efficiency of buildings, there is a problem of decrease of the available interior space affected by the reduction in U-value of parts of thermal building envelope, i.e. an increase in thickness of insulating layer, which is especially present in unheated staircase. Having in mind that present methods of calculation of transmission heat losses through elements of thermal envelope include the adjustment factor which regulates designed temperature conditions if the temperature at the colder side of the element of the thermal envelope differs from that of the external environment, this paper strives to demonstrate that in the case of unheated staircases, this fixed value should be reconsidered and treated as a variable depending on the morphology, i.e. form, size and position of the staircase within the building. This problem has been analyzed on the example of Serbian housing stock and relevant national thermal regulations. Three morphological types of unheated staircases have been distinguished within which three models have been defined and examined with respect to variations in number of floors and percentage of glazing. Average temperatures of staircase volume and temperature correction factors were calculated in following temperature modes: stationary that excluded solar gains and ventilation heat losses and gains, and dynamic with variations in air exchange rates and insolation conditions, expressing in all of the cases variations in calculated values of temperature correction factors in comparison to the prescribed fixed value.

Traditional rural houses are one of the most endangered forms of cultural and built heritage in Serbia today. In the past, the building of rural houses was in interaction with nature and the conditions of the immediate environment, especially in terms of its climatic and geographic properties. Today, they are often abandoned to decay, or replaced with new buildings, removing any connection with tradition. Problems related to their protection and regeneration to a great extent could be connected either with the properties of the original materials used for their construction, since they are usually not very durable, or with the level of how comfortable they are, which falls below modern living standards. Through a review of types and methods of building of the so-called half-timbered (bondruk) style houses, as well as an analysis of their achieved thermal performances and potentials, this paper strives to point out the real need for their modernisation and optimal possibilities for their energy improvement, with respect to the need for the protection of their integrity and authenticity during the renovation process.

In addition to reducing the energy consumption in residential buildings, the Rulebook on the energy efficiency of buildings, which was recently enacted in Serbia, also pays special attention to the issue of energy performance of the existing buildings. On the other hand, in the course of a few decades researchers all around the world are showing tendencies towards inclusion of embodied energy into the calculation of the overall energy consumption in the residential sector instead of just employing the most frequent and widespread calculation of operational energy. Thus, the aim of the paper is to determine the quantity of embodied energy on the example of the external wall of selected residential buildings, before and after the process of energy performance optimisation, in four different scenarios including four different insulation materials. A selection of seven house types, which were deemed representative for this research, was conducted on the example of Sombor, a typical town in Vojvodina, i.e. a typical town in Northern Serbia. Two criteria were involved: the applied materials and the representation of buildings constructed in different time periods. The issue of improving the thermal features of the external walls is analysed, since it was previously determined that none of the selected buildings satisfy the maximal value of thermal transmittance U, as stipulated by the latest Rulebook from 2011 (Ministry of Environment, Mining and Spatial Planning MEMSP 2011a). The methodology for the embodied energy evaluation in 1 m2 of the external wall was created on the basis of the grouping of life cycle phases into building’s energy use categories: initial embodied, operational, recurrent embodied and demolition energy; and into the system boundaries: cradle to gate, cradle to site, cradle to grave and cradle to cradle. After taking into consideration, the life cycle phases of the external walls’ building materials and subsequently installed insulation materials, it was determined that in terms of consumed recurrent embodied energy, the local insulation materials typical for the region of Vojvodina, are more preferable in relation to the widespread artificial materials.

In recent years, a series of students? projects have been carried out at the Faculty of Architecture of Belgrade with aims at protection and investigation of possibilities or presentation of archaeological sites dating from the Roman period, in which Serbia is very rich, and their active inclusion in modern way of life and tourist programs. The project for the revitalization of the Roman military camp Timacum Minus was one of them. It showed that the students? involvement in resolving complex issues of the presentation and revitalization of archaeological remains was fruitful because numerous fresh ideas were obtained in numerous subjects. The focus was on a concept that significant cultural and historic areas with ancient remains were to be presented to both the domestic and foreign public in a modern manner and in interaction with the environment, the natural beauties of the landscape. The projects enable to promote an interactive relation with the historic area as a place where visitors, at various activities, meet with history, but also with a reflection of a modern era.

World and especially European trends of tourist economy are mainly focused on development of diversity in cultural tourism. Cultural tourism is a complex of numerous activities that enables not only the affirmation of cultural-historic motives, but also provides important resources for renewal of cultural-historic monuments, tangible and intangible heritage and resources. Today, there is no serious and ambitious country that does not prefer development of tourism in its development strategies as a planetary phenomenon and development sector. This specially refers to cultural tourism, as a competitive segment, based on local authenticity, unique areas, urban entities and ambiance, different historic layers and monuments, local tradition, myths and customs, affirmative mentality of population, geographic and ecological resources, in brief - complex and original identity of its area and its population. Cultural tourism in Montenegro has a modest tradition and only recently through valuable but sporadic initiatives and encouragements from Europe, attempts to valorize its own potentials, making them competitive through creative projects and programs. It is most certainly that the Montenegrin coast is a deeply settled part of complex Mediterranean cultural sphere that possesses certain characteristics which marks it as a unique cultural space in which different historical, geographic, confessional and other influences from surroundings intersect, predefining it for development of cultural tourism. This paper represents an effort to create a professional study report, although limited to single destination - city of Budva that treats cultural tourism in correlation with evaluation of renewal and use of cultural-historic and built heritage. From the mentioned reasons and within described context, this paper tends to be a small, but precisely created contribution to the future actions of creating complex tourist offer at Montenegrin coast, especially in Budva as its 'capital', as it is often emphasized with reasonable expectations in public. .

Brick was proved to be one of the main building materials in the region of today’s Serbia, especially in the time of late antiquity and in the following medieval time. Hence, the idea was born to make a comparison between the main characteristics of late antique and medieval bricks and brickworks from this region that could confirm the continuity and variety of its use. A question of evolution of the use of bricks was partly based on comparison of their estimated properties and also on comparison of applied building techniques and known characteristics of brick production. It has been confirmed that although it is possible to discuss and confirm the continuity in the use of bricks and adequate building techniques, up-to-date research based on quantitative analysis of historical bricks do not offer enough comparable data regarding their quality. Therefore a new field of possible qualitative research is needed in the future.
