Large panel residential buildings, dating from second half of 20 Century, are to be found in almost every urban settlement across Europe. Within the context of three case studies of urban blocks in Bulgaria (Mladost - Sofia), Macedonia (Karpos III - Skopje) and Serbia (Detelinara - Novi Sad), comparative analysis and evaluation of technical and structural characteristics according to reliability (seismic resistance and fire safety) and sustainability (energy efficiency, internal air quality, accessibility) criteria has been conducted. Additionally, previous experiences from individual renewal projects are reviewed. Previous experiences and comparative analysis results, could contribute to formulation of wider applicable solutions and development of new urban renewal strategies.

The general objective of this article was to promote through bibliographic studies the two types of lamps, in addition to the comparative analysis of compact fluorescent lamps versus LED lamps: an economy factor. The specific objectives were: - to explain the conceptual precepts on: lighting engineering, definitions, characteristics, invention, operation, defect, quality and the environments used and the NBRs regulations; - address the economic impact generated by the choice of LED lamps and compact fluorescent lamps; - emphasize on an economic feasibility study on the use of LED lamps and compact fluorescent lamps. The justification of the study is related, in the promotion regarding the use of LED lamps and compact fluorescents, in the factor that generates savings. Since the areas related to artificial lighting are responsible for a significant portion of energy demand, both on a large scale - such as lighting for public roads or industrial buildings - and on smaller scales - in commercial and residential buildings. Therefore, its promotion is crucial in the context of economic viability. The lamps provide the luminous energy, through which a better luminous efficiency is obtained. Currently, there are several types of lamps available, different in several aspects: luminous intensity, reproduction colors, energy efficiency, physical composition, method for emitting light, specific purposes, prices, among others. It is worth mentioning that the lamps differ from each other not only by the different luminous fluxes that they radiate, but also by the different powers they consume. In order to compare them, it is necessary to know how many lumens are generated per absorbed watt. This greatness is called energy efficiency. Thus, the proposal of a study was evidenced, in order to promote these luminous resources, in addition to emphasizing their economic viability.

Radon Concentrations

A comparative analysis of the radon concentrations in modern multi-storey residential buildings of high energy efficiency class and buildings typical for urban areas of the twentieth century was carried out. The study was conducted in Russian cities located in various climatic zones – Ekaterinburg, Krasnodar, St. Petersburg, Salekhard, Chelyabinsk. The radon concentration in samples of buildings was measured using integrated radon radiometers based on nuclear track detectors according to a single method. The surveyed sample included 498 apartments in multi-apartment buildings. Among all the examined building types, the highest average radon concentration is observed in modern energy-efficient houses – 43 Bq/m3. In other types of buildings, the following average radon concentrations were obtained: brick 2–5 floors – 35 Bq/m3; panel 5 floors – 32 Bq/m3; panel 7–12 floors 1970-1990 years of construction – 22 Bq/m3; brick> 5 floors 1970–1980 years of construction – 20 Bq m3; panel, built since 1990 – 24 Bq/m3. The results of the study confirm the assumption that radon concentration in modern multi-storey energy-efficient houses is on average higher than in typical residential buildings of the Soviet period. The increased accumulation of radon in energy-efficient buildings is associated with a decrease in the building envelope permeability and the contribution of fresh air to the general air exchange. Despite the fact that there were no cases of exceeding hygienic standards for the indoor radon concentration in the framework of this study, the higher radon concentration in buildings of increased energy efficiency requires attention from the point of view of implementing the principle of optimization of radiation protection. In the future, extensive construction of energy-efficient buildings may increase the average and collective doses to the urban population in the Russian Federation.

Modular blocks of flats built with large prefabricated panels have become widespread in most of central and East-European countries particularly in the 80es, populating large-scale neighbourhoods. In Romania are representing about 37% of the total fund of apartment blocks, being present in most of the cities. The high percentage of thermal bridges and reduced design thermal resistance of the envelope make these buildings a priority in thermal retrofitting. Using up-to-date calculation methods, the paper presents a thorough analysis of the energy performance of large-panel residential buildings (apartment blocks) before and after renovation. The conclusions are focused on the practical measures to be undertaken for bringing the energy efficiency after retrofitting at the highest possible degree, thus meeting the requirements of the EU legislation and the targets set in the field of energy performance and reduction of CO2 emissions.

The main objective of this paper is to evaluate the thermal properties of existing residential buildings built in industrial manner in Novi Sad from 1960 to 1990 based on building typology. Each of three analyzed building type has its characteristic fa?ade, with thermal performances divided into periods according to the development of domestic thermal protection building codes. The necessary layer of subsequent insulation is determined by calculations in order to comply with European standards, also applied in Serbia from 2012. The proposed method of periodization simplifies the process of thermal performance assessment and it was checked through the case studies. Evaluation of energy consumption rationalization has been done through comparative analysis of energy losses. Based on the most common energy rehabilitation measures applied in Serbia, it was estimated that it was possible to reduce the energy losses in heating up to 60%.

The article is devoted to the issues of ontology, research of the effectiveness and prospects of large-panel and monolithic reinforced concrete construction of residential objects. Increasing demands on the effectiveness of multi-story housing construction determine the relevance of this study. Methodological foundations of substantiation and a comparative analysis of the effectiveness of monolithic and large-panel reinforced concrete multi-story construction are considered; prospects for the development of these housing technologies are justified. The article presents an analysis of the pros and cons of monolithic and large-panel reinforced concrete multi-storey construction of residential buildings, a comparative analysis of the processes of organization and technology of construction works. The problems of large-panel and monolithic construction are ranked according to the level of their materiality, measures to improve construction technologies are proposed. The comparative analysis of cost indicators of monolithic and panel construction on the basis of the data presented in collections of standards of the price of construction is presented. The need to introduce and update the normative documentation having legal force for regulation of the basic provisions of the modern improved large-panel construction is proved. Attention is paid to the design conditions for the manufacture and installation of the monolithic and large-panel multi-storey construction of residential buildings used in the methodological approach. Cases of expediency of comparison on criterion "duration of construction" are analyzed. The article proposes an original methodological approach for evaluating the effectiveness of monolithic and large-panel construction, taking into account the conditions and nature of the uncertainty of the initial data, which will justify the choice of the most effective options for the construction of multi-storey housing construction.
