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.

The study presented in this paper assessed the multidisciplinary approach of geothermal potential in the area of the most southeastern part of the Pannonian basin, focused on resources utilization. This study aims to present a method for the cascade use of geothermal energy as a source of thermal energy for space heating and cooling and as a resource for balneological purposes. Two particular sites were selected—one in a natural environment; the other within a small settlement. Geothermal resources come from different types of reservoirs having different temperatures and chemical compositions. At the first site, a geothermal spring with a temperature of 20.5 °C is considered for heat pump utilization, while at the second site, a geothermal well with a temperature of 54 °C is suitable for direct use. The calculated thermal power, which can be obtained from geothermal energy is in the range of 300 to 950 kW. The development concept was proposed with an architectural design to enable sustainable energy efficient development of wellness and spa/medical facilities that can be supported by local authorities. The resulting energy heating needs for different scenarios were 16–105 kW, which can be met in full by the use of geothermal energy.

Kindergartens are probably the very first public buildings we actively use in our lives. Therefore, they can be considered as the physical structures that are providing for the very important educational and social function. Additionally, they can also be considered as the specific learning tool for future generations where they can encounter the ideas of green and energy-efficient buildings. One of the results of the research project ?Energy efficiency in public buildings? has been formulated through the development of Serbian National Typology of Kindergartens which was conceived as a specific tool that can be used for improving this portion of building stock. The paper presents the methodology for identification of typical kindergarten buildings, covering various construction periods, building sizes and illustrates the type of analysis performed for model representatives. The potential for energy upgrades covering physical structure, installed technological systems, as well as expected impact on energy performance, has been estimated. The study presents results based on the analysis of the data derived from the National Typology, stressing out that energy retrofits of large and medium-sized kindergartens built during the 1970s and 1980s should be the primary focus of refurbishment activities. Accounting for almost 60% of total buildings and 69.59% of heated area, they are responsible for 75.97% of energy demands. Estimated energy savings of more than 60% indicate the effectiveness of their retrofit. The paper also presents the potential uses of National Typology as a retrofit tool on various scales, from single-building considerations to a strategic approach at the national level.

Developments conceived following the principles of Athens Charter were typical form of urban answer to the post-war housing shortage and during the decades of intense construction activity that followed. In city of Belgrade, multifamily housing in open city blocks built between 1961 and 1990 account for about 40% of current housing stock. The current ownership and operation of these housing blocks derive from their socialist legacy: home-owners rights relate only to the buildings, excluding any open spaces, even the ones immediately along the building?s perimeter. On the other hand, heating is supplied by district heating system. Management of open spaces as well as provision of district heating are subordinates to local municipality (the city of Belgrade). Energy efficiency related refurbishment options for these developments that would engage both the home-owners and the public companies may be the key for bringing ever-needed modernization, prolonged lifespan and a sustainable way of using this portion of housing stock. By applying simple architectural measures, energy demand for heating of these buildings can be reduced by 30-78%, which opens a pathway for effective use of renewable energy sources. Unlike solar energy, which can be managed at building level, geothermal energy can be exploited only at the district level due to the ownership rights. The presented research explores the effectiveness of using geo-thermal energy at a district level coupled with systematic approach to building refurbishment, taking the advantage of the repetitive use of the same building design and the formal and practical relations with local authorities.

The aim of this research is to examine and analyse the thermal characteristics of the fa?ade modular element. The possibility of optimization of the fa?ade coating with vegetation is examined experimentally in this research, with the aim of improving the thermal characteristics of the fa?ade wall. This element is made of perlite concrete in which the greenery is implanted. The scope of the research is experimental and theoretical testing the possibility for optimizing the fa?ade coating with vegetation. The energy specificities of modular vegetation elements and their contribution to the improvement of the thermal properties of the fa?ade wall are analysed in the experimental part of the research, the elements of vegetation are treated as the elements which influence the decrease in surface temperature of the fa?ade coating. The modular elements in this research are placed on a reference wall surface facing the South. The methodology presented in this paper is based on the study of climate characteristics in city of Belgrade, experimental measurements of test models, and comparative analysis with the reference wall. During the experiment, the data on the external climate parameters and the coefficient of heat transfer through the wall were continuously measured. Conducted measurements and analyses show the vegetation influence on the reduction in surface temperature of the outer wall and the heat passage through the fa?ade coating. The experiment used a modular model and several plant species. It is noticeable that vegetative walls with green areas covered by plant shells play an important role in the harmonization of the parameters of the microclimate in relation to the local environment.

Developing countries are facing numerous challenges in the process of providing adequate health care to often deprived and diminished social groups. Being a country made up of a mainland territory and five islands in Gulf of Guinea, al-most entirely covered by tropical rainforest, with poor road infrastructure, Equatorial Guinea is a showcase of various obstructions in developing effective health care system. The paper explores guidelines for creation of model regional hospital, commissioned by Ministry of Health and Social Welfare, with the aim of achieving high level of replicability through minor program and site-specific adjustments. The demonstrated strategies are applied on a local hospital designed to provide all basic types of health services while retaining a high level of technical independence. The architectural concept was formulated aiming to maximize the use of natural ventilation, daylight, and rainwater management, leaving the operation block, laboratory, and intensive care unit practically the only parts of the structure that would need mechanical air conditioning. The potential and effectiveness of use of photovoltaic units in enhancing hospital?s resilience through on-site energy production was explored. The structure was designed having in mind local climate, culture and customs, thus offering a possibility of strong integration with local community. The building technology was thought over to enable efficient and cost-effective construction and proper resilience for tropical rainforest environment. The result is a structure providing for contemporary, high quality medical service, interpreting local climatic and cultural con-textual premises through modern architectural expression.

As a part of a scientific project conducted at the Faculty of Architecture University of Belgrade a detailed survey of building fund has been made and a typical 1950?s building was chosen as a demonstration project for the energy conscious renovation and retrofit procedure. Rehabilitation has been done in three main phases: detailed analysis and inspection of present state based on available project documentation, on site inspection, thermography, as well as interviews with tenants. In this phase strategies for reconstructions were analyzed and evaluated; first phase of rehabilitation mainly concerned improvement of performance of envelope (fa?ade, windows) with addition of an attic level;. second phase maximizes performance of building using various architectural and technical methods. Addition of new volumes (glazed loggias, and partly double skin fa?ades), heat recuperating units, and hot water collectors with redefinition of heating system was the main objectives. For both phases techno-economical analyses were made optimizing possible thermal performance gains and used technology in accordance with economic potential and pay-back period. Also a detailed procedure algorithm was developed in order to give guidelines for future projects of this type.
