Member states of European Union have large stock of residential buildings that require urgent renovation in order to reach carbon neutrality by 2050. In our paper we provide a preliminary evaluation of preconditions of such goal within the context of shrinking regions. Our data originates form renovation subsidy database of large renovation programme managed by state fund and form Nation Statistical Bureau. First we estimate the potential of apartment buildings occupation within the next 30 years. We exclude buildings that are going to be abandoned due to the demographical and migration reasons. Next we calculate the potential of construction sector to deliver required amount of renovations. We observe that the in our case current renovation rate must at least be increased by factor of three in order to comply with the carbon neutrality goal. This, however, is very challenging because supply of renovations’ construction is limited and overstimulated demand could increase construction prices significantly while rendering the effect of state incentives inefficient. Therefore an urgent technological change in renovation delivery is required to reach carbon neutrality goals.

Improving the energy efficiency of facilities should reduce greenhouse gas (GHG) emissions and independence from energy imports, increase jobs and energy security, as well as encourage researchers in further research to be creative, innovative and competitive. With about 40% of primary energy consumption accompanied by 36% of greenhouse gas emissions, the construction sector is one of the largest consumers in Europe. Energy consumption of the construction sector in Serbia has a significant share in total energy consumption of 48%, 65% of which refers to energy consumption in residential buildings. The legislation on Energy efficiency in Serbia implies a specific energy consumption of 65[kWh/m2] for one apartment buildings and 60[kh/m2] for multi-apartment buildings.  In this paper, a settlement with 50 apartment buildings is analyzed, impact on building envelope construction and applied heating system type to carbon and primary energy footprint is estimated using the degree-day method. Although the mentioned specific energy consumption limit is determined by national legislation, this paper tackles the benefits and costs of reducing energy and carbon footprint by reducing carbon and primary energy footprint to a value lower than the mentioned limit.

The article is devoted to one of the actual problems concerning the current state of the facades on apartment buildings in residential districts in Kiev - videoecology. The main purpose of the article is to determine the degree of visual aggressiveness of multistorey residential buildings in Kiev. It also investigates the problem of finding the optimal criteria for creating an ecologically healthy and friendly inhabited environment in the capital city of Ukraine. The modern visual environment in the capital is contaminated, not only because of the increasing numbers of promotional billboards, but also because of the contemporary architecture of high-rise buildings such as office buildings, apartment buildings. Their composition is usually based on a simple description of a rhythm. There are also repetitions of the end parts of buildings in ?lowercase? buildings, which are high-rise buildings that alternate with nine or identical apartment groups. It creates a sense of oppressive monotony and leads to psychological and visual fatigue, especially when these repetitions are the only pattern the eye perceives. In the article a theoretical block of ecological-aesthetic criteria is defined, which must be met by the modern architecture facades of multistorey residential houses in Kiev.

Background Gamma Radiation

Introduction. The article addresses background gamma radiation in residential premises of apartment buildings in Vladivostok. This study is based on earlier research undertakings focused on the sick building syndrome (SBS), which proves its high relevance. The research is focused on the intensity of background gamma radiation in the residential premises of apartment buildings in Vladivostok. New data obtained in the course of the field experiments, the scale of their analysis, the coverage of substantive issues concerning radiation intensity and its monitoring in residential buildings guarantee the novelty of this research project. These findings also have a practical value that deals with environmental safety. Materials and methods. Onsite examinations were conducted in the form of background gamma radiation measurements taken in versatile apartment buildings, built at different times and made of different materials. Results. This section contains analytical information about the lack of influence of the location of apartment buildings on background radiation inside the apartments examined within the framework of this research project. Measurement results represent a range of values depending on construction materials used. Principal regularities, derived from the measurement results, are based on the time of operation of residential buildings, which is of practical importance. Conclusions. Patterns of influence of building parameters on background radiation inside apartments allow to assess the condition of residential buildings. Background radiation information can be entered into BIM databases and used to formulate the approach to the design of buildings and urban infrastructure so that they were focused on their residents and users. Background radiation research findings, entered into the database and contributed to design algorithms which are customized to the needs of urban residents, will enable designers to project the overall quality of the living environment encompassing the built environment analyzed in this article and other nearby buildings and structures located in Vladivostok.

More than 2 million houses in Australia have installed solar photovoltaic (PV) systems; however, apartment buildings have adopted a low percentage of solar PV and battery storage installations. Given that grid usage reduction through PV and battery storage is a primary objective in most residential buildings, apartments have not yet fully benefited from installations of such systems. This research presents shared microgrid configurations for three apartment buildings with PV and battery storage and evaluates the reduction in grid electricity usage by analyzing self-sufficiency. The results reveal that the three studied sites at White Gum Valley achieved an overall self-sufficiency of more than 60%. Owing to the infancy of the shared solar and battery storage market for apartment complexes and lack of available data, this study fills the research gap by presenting preliminary quantitative findings from implementation in apartment buildings.

PurposeFrom the consumer side, this paper aims to highlight some of the various characteristics that older renters seek out from their apartment buildings, relative to conventional multifamily residential buildings and, from the operational side, to examine some of the costs involved in daily operation of such buildings.Design/methodology/approachThe Rental Housing Finance Survey provides data that enables scholars to test empirical differences in amenities and costs between senior-oriented communities and other apartment buildings.FindingsOccupancy rates outpace the rate for all other apartment communities. Regarding amenities, senior apartment communities are more likely than other communities to have a fitness center on premises, but less likely to have a swimming pool. Market value for senior properties is usually less than properties marketed toward multi-family property tenants. This difference may be due to a higher pattern of both operating/capital expenses within senior communities. Part of these increases in operating costs is due to a higher propensity to hire professional management companies and a higher fee for managing senior apartment communities.Originality/valueLiterature on seniors living within apartment communities is somewhat sparse, particularly regarding the operational aspects of managing apartment communities. There is a dearth of information on industry success measurements known as operating and capital expenditures. This study triangulates multiple sources of data to investigate differences in cost of senior housing apartment communities, as well as amenity structures.

During the last decades, only a little attention has been given to the design and renovation of the entrances to residential buildings. Given underestimation of the problem in the design has resulted in a negative impact on both indoor building environment and aesthetics of the building. Recently, together with the renovation of external walls claddings (by application of additional thermal insulation and replacements of windows and doors) and upgrading and modernizing the installations services such as heating and plumbing systems, also the entrance construction components finds their place in the renovation process. This article analyses the problems connected with renovation of building entrances and summarizes information about the current efforts in engineering and architectural praxis.

Currently, the construction sector is facing requirements for higher quality and efficiency standards as well as objectives related to value creation. In construction, rational decision-making problems often involve creating a unique complex of criteria, which must consider multiple requirements and conditions. The paper presents the developed model for the selection of multi-layered external walls of a residential building. The model considers the following aspects and parameters: time, cost, quality, environmental conditions, aspects of sustainable development, and problemsolving benefits received from the assessment of alternatives and the development of the model. Game theory was used to calculate the defining rational decision. For the calculations was used game theory: Bayes, Wald’s rule, Savage criterion, Laplace’s rule. This study presents the developed model for the selection of multi-layered external walls of a residential building and calculation results based on game-theory rules, which are effective tools for rational decisionmaking.

Introduction. The economy of any region includes various types of activities. Building development models of individual sectors of the economy contributes to the rational allocation of productive forces, expedient use of economic resources as well as to the comprehensive development of the country’s regions. This determines the relevance of the chosen research topic. The main objective of the analysis is to build models of functioning of the main types of economic activities in the regional context. Materials and Methods. The conducted research applied multidimensional techniques of the regression and factorial analysis by building dependencies of the volume of economic activities of various sectors of the regional economy (based on the initial socio-economic indicators provided by the Territorial Authority of the Federal State Statistics Service in the Republic of Mari El and the integral indicators obtained on their basis). Results. Modeling the region’s economic activity made it possible to identify the factors the change of which directly impact the functioning of the relevant sectors of the economy. In agriculture and the construction sector, the cumulative factors that largely characterize the functioning of these types of activities have been identified based on the integral indicators: the factor of livestock production and the factors of commissioning apartments and living space. The study has proved the greater focus of agriculture in the region on the livestock products with a bias on milk production. The analysis of the construction sector in the Republic of Mari El has revealed the predominance of the commissioning of residential buildings as compared with the construction of industrial and civil buildings as well as social and cultural facilities among the implemented construction projects. Modeling the transport sector has proved a significant dependence of the volume of passenger traffic in the Republic of Mari El on the availability of private vehicles. Discussion and Conclusion. To provide further progressive development of the agriculture and the construction sector of the region, great attention should be paid to the development of crop production within the agro-industrial complex of the Republic of Mari El as well as to the construction of industrial and civil buildings, social and cultural facilities. The results obtained can be used when conducting research on the development of the regional economy or drawing up strategic plans for the functioning of the economic sectors.

AbstractConstruction companies are important economic actors in every country. Their activity translates into employment levels, tax revenues, and the provision of new spaces that require further expenditure on equipment, thus stimulating consumer spending. The activity of construction companies depends on the demand for space, the state of the economy and the financial market. Undoubtedly economic disturbances in the form of a recession have a significant impact on construction activity. The authors were interested in whether the boom and recession in the selected countries were similarly reflected in the activity of construction companies. In particular, they were interested in residential construction activity, although it was not possible to select companies that would only deal with residential construction. The authors selected four post-socialist countries and two countries which are called winners of the integration process due to their enormous economic growth. The authors outline the residential construction and construction sector results and activity in the Czech Republic, Poland, Slovakia, Hungary, Spain and Ireland, and draw a wider picture for analyses of construction companies’ financial results for the years 2003-2012. This period was chosen because it covered periods of both boom and bust. All enterprises were part of the sector denoted in the Amadeus database as primary code: Eurostat NACE Rev. 2 with codes: 41 - Construction of buildings: 4110 - Development of building projects, 4120 - Construction of residential and non-residential buildings. Due to the specificity of the construction sector the authors divided the surveyed enterprises into two groups – all companies; and only large and very large companies. It was not possible to separate data specifically with respect to residential construction companies.
