Abstract: The problem of renovating a residential district of multi-storey apartment houses is analysed. Multi-storey buildings make a large percentage of all housing facilities. Therefore, renovation is a significant problem for most countries. Germany has great experience in renovating multi-storey apartment houses, and therefore could be usefully applied under Lithuanian conditions. To increase the efficiency of renovation, a complex approach to this process, including the modernization of the whole residential district, should be used. The present paper considers the strategies of modernizing Hellersdorf district in Berlin embracing the problem of sustainable renovation and building management, the differentiation of dwellings supply in order to maintain a mixed social structure, the development of the city centre as a functional core in the district of multi-storey apartment houses, improvement in life standards and quality, the integration of residential houses into the existing environment, the development of democratic planning and the selection of partners.

Energy-Saving Potential of Building Envelope Designs in Residential Houses in Taiwan  [PDF]
Chi-Ming Lai,Yao-Hong Wang
Energies , 2011, DOI: 10.3390/en4112061
Abstract: The key factors in the energy-saving design of a building’s exterior in Taiwan are the thermal performance of the roof and window glazing. This study used the eQUEST software to investigate how different types of roof construction, window glasses and sunshield types affect the energy consumption in residential buildings under common scenarios. The simulation results showed that the use of an appropriate window glass significantly reduced the annual energy consumption, followed by the shading device, whereas the roof construction produced less of an energy-efficiency benefit. By using a low-E glass and a 1.5 × 1.5 m box shading (e.g., balcony), this could save approximately 15.1 and 13.6% of the annual electricity consumption of air conditioners, respectively. Therefore, having control over the dominant factors in the building envelope is indeed an important step in the path to achieving energy savings and carbon reduction in residential houses.

Straipsnis lietuvi kalba The most of multi-apartment residential houses in Lithuania were built before 1993. Most of these houses are uneconomical, unecological and consume a significant amount of heat energy. Such multi-apartment houses need to be modernized, and, therefore, it is important to examine and analyse their state. This paper discusses the state of structural elements of multi-apartment houses, their deterioration level, heat energy losses, as well as the problems of microclimate in the premises, layout and living environment. Modernization of buildings is effective only when the state of buildings is carefully analysed and the most suitable renovation method or scenario is selected. Article in Lithuanian

Abstract: In this paper, presented is the state of the art of Energy Efficiency (EE) of residential buildings in Serbia. Special attention is paid to energy efficiency in already existing buildings. The average energy consumption in residential buildings in Serbia is over 150 kWh/m2 per year, while in developed European countries it is about 50 kWh/m2 per year. In this paper examined is the contribution of ventilation losses, through the windows of low quality, regardless whether they are poorly made, or made from bad materials, or with no adequate glass. Besides ventilation losses, which are of major importance in our buildings, special attention is paid to transmission losses, which are consequence of the quality and energy efficiency of the facade. All of the above statements are proved by measurements obtained on a representative building of the Block 34 in New Belgrade, built in the eighties of the last century. In addition to measurements performed the calculation of energy consumption for heating during winter has been made. The results of two different methods of calculation of energy consumption for heating are compared with the values obtained by measuring.

Journal of Applied Sciences , 2009,
Abstract: This study presents the Overall Thermal Transfer Value (OTTV) and the energy consumption of room air conditioners of the residential buildings in Malaysia. A survey has been conducted to investigate the OTTV and the energy consumption of room air conditioners of the residential buildings in Malaysia. OTTV calculation, energy consumption and effect of the building parameters on energy consumption have been investigated. It is found that OTTV of the residential buildings in Malaysia varied from 35 to 65 W m-2 with a mean value of 41.7 W m-2. The sensitivities of several parameters such as window to wall ratio (WWR), Shading Coefficient (SC), U-value for wall (Uw) and solar absorption (α) are provided to design and optimize the thermal performance of residential buildings. It is found that U and α influence more on OTTV compared to other parameters. The analysis shows that about 14, 10 and 5% of residential building air conditioners have annual electricity consumption in the ranges 500 to 1000 kWh, 1000 to 2000 kWh and 7500 to 10000 kWh, respectively. The maximum, minimum and average annual electricity consumption of the air conditioner of residential buildings is 22055.5, 136.1 and 3708.8 kWh, respectively.

Facta Universitatis Series : Architecture and Civil Engineering , 2011, DOI: 10.2298/fuace1102261g
Abstract: This paper examines specific conceptual approach to the implementation of new "smart" materials having phase-changing own characteristics and maximum potential for their installation and exploitation of their performance in the commercial and residential buildings architecture. Such approach somewhat changes the usual traditional practice of installing "classical" materials, i.e. installable components into the architectural structure. The immeasurably superior performance of new elements installed in the architectural system is thus utilized, to the total energy benefit of the structural system. Using new "smart" components would result in energy cost-effective impact, reflected in the reduced the overall energy consumption of a given structure as well as in better effect sustainability of buildings in bioclimatic terms at the micro and macro levels in comparisonto the usual performance of traditionally constructed buildings.

Journal of Applied Sciences , 2009,
Abstract: The aim of the study is to emphasize the actual demands of residential buildings` users and to explore new methods, yet less used, that could improve the buildings environmental comfort. The residential buildings, constructed by man in order to function as shelter where multiple processes of the social and material life takes place, are influenced by many factors that have to be taken under consideration when projecting, constructing, using and post-using them. All aspects emphasized in this study should be first considered in the processes of their interaction and interdependency and then to be systemically approached and analyzed. During the second half of the twentieth century, the urban population knew an incredible growth. This growth led to an exponential increase of the energy consumption and a more than alarming exceeding of noxious gases in the air and wastage. There was a time when the energy consumption was considered an indication of the quality of life. Therefore, from the point of view of the energy consumption, many differences appeared between the developed countries and the developing ones. At the same time a person living in one of the developed countries has energy consumption twenty-five times greater than one living in a poor country. A popular idea was that we can fight poverty with increased energy consumption. However, the facts showed a disturbing reality energy wastage.

Abstract: Dust samples were collected from 141 urban and 191 rural houses. Der f1 + Der p1, Can f 1, and Fel d1 levels were measured and associated with residential conditions and atopy-related health outcomes assessed by clinical examination and skin prick testing.Concentrations of mite allergens were lower, and cat and dog allergen levels were higher in urban houses. Fel d1 and Can f1 levels depended on the presence of a respective animal in the house. In urban houses, Der p1 + Der f1 concentration was lower in households with central heating, whereas Can f1 concentration was related to building age. Multivariate analyses revealed that the concentrations of house dust mite and dog allergens were associated with relative humidity, number of people in the household, and the presence of a dog at home. There was no significant association between allergen level and sensitization or atopic diseases.Concentrations of indoor allergens in urban and rural houses differ significantly, and residential conditions associated with allergen levels seem to be different in both environments.
