A model of a Serbian energy efficient house for decentralized electricity production

This paper presents architectural project and simulation of energy consumption and production of a model of Energy Efficient House for Decentralized Energy (DE). The house model is designed for the area of Serbia, based on the needs of an average Serbian family. The model is designed to investigate opportunities for DE of typical house geometry with advantages of passive solar architecture combined with active solar systems and heat pump. Simulation of the model was performed for the climate conditions for the city of Nis. Thermal load for designed net-zero energy efficient home for a period of one year was simulated by means of trnsys software. With respect to renewable energy sources in Serbia, production of electrical, heating, and cooling energy by solar photovoltaic/thermal collectors, heat pump, and heat storage is considered. The balance of simulated annual electricity production and consumption show that the house model can produce 51% of its energy demands. Simulation results are used to determin...

Revitalization of residential complexes in the context of housing quality improvement

The housing quality improvement is a continual and topical process which lasts for several decades in the developed country. The priority of each society is the revitalization of those residential complexes which have the basic urban values disrupted. In the transition period, which is where our country is, it is necessary to create and modernize the planning approach and regulations for revitalization. The paper provides the guidelines for the revitalization of the residential complexes in Nis which could serve as basis for improvement of conditions and quality of housing.

Urban green areas planning and development: An assessment of general urban plans of the City of Nis

Urban green areas have multiple roles in cities and to a large extent they determine the quality and livability of urban space. The process of urbanization has led to an increase in construction in cities and reduction of open public spaces, especially green areas. Planning of urban green areas is an integral part of urban planning, thus changes in planning and development of urban green areas can be observed through urban planning documents. The main question is whether the loss of green areas is a consequence of non-compliance with plans, or the reason for this lies in the method of planning of green areas. In order to answer this question the paper discusses: functions, standards and classification of urban green areas in general, and their use in two successive general urban plans of the city of Nis in the last twenty years, as a prerequisite for the development of green areas in accordance with growing need for green areas in the city.

Sustainable development of the protected areas with the reference to the Sicevo gorge

The goal of this paper is to test the topical and possible application of sustainable development principles in the protected areas. The sustainable development is observed as a goal and the flexible mechanism for reaching the consensus set by the fundamental postulates of the Agenda 21, among all the relevant factors in the decision making and enforcement of regulations. It is unquestionable that the spatial planning possesses the necessary integrative potentials for management of changes, long term time horizon and the catalytic position in reconciliation of public, social and private interest. The road towards sustainability is a long and complex process, because it requires the change of the way of thinking and behavior of all the social factors, that is, establishment of the understanding the environmental effect of the development is as important as the economic one. The main guidelines of this reconciliation must be the vision and the aims of preservation of natural resources, but not as the ultimate requirement of the authorities, but as the argument-supported and articulated public interest. This paper refers to the Spatial plan of the special area of Sicevo gorge through the review of basic regimes of natural resources protection, restrictions and prohibitions. It also pays attention to the measures which will allow to achive sustainability of development as well as apply protective regimes.
