Pollack Periodica, 2011
Building industry is responsible for 1/3 of total CO 2 emissions and consumes 40% of primal energy in the industry. This paper presents the results of environmental impact assessment of building materials in three houses based on Life Cycle Assessment of the whole life cycle. Building materials were evaluated by special tool by Createrra. CO 2 emissions related to life cycle of building materials vary from 0,176 kg CO 2eq /kg -0,305 kg CO 2eq /kg, SO 2 emissions range form 0,836 g SO 2eq /kg -1,656 g SO 2eq /kg and primal energy intensity reached values from 2,347 MJ/kg to 2,534 MJ/kg.
Analysis of Environmental Aspects in High Energy Performance Family House - Case Study
In general, high energy performance building design ranges from architectural design to the application of technologies for energy conversation. Many applications are focused on insulation of facades, roofs and floors to those that are used systems for renewable energy sources. The aim of the innovations is not only energy saving but also reduce costs and preserve natural resources. One key element of high energy performance building design is use of basic form and enclosure of a building to save energy while enhancing occupant comfort. Besides energy need for building operation the significant part of the total energy is energy used in the extraction, processing and transportation of materials used in building structures. Integrated assessment of building includes energy produced over the entire life cycle of building. In order to reduction of embodied energy and embodied emissions, this study is aimed to analyze the building materials and structures used in high energy performance...

Building materials as principal components of building constructions and entire build ings play an important role in overall impact on the environment. In this paper, the environmental assessment of building materials in selected building in the Slovak Republic using life cycle assess ment data is presented. Environmental parameters, such as the amount of primary energy, global warming potential and acidification potential together with weight of used materials were evaluated. For selected constructions, the alternation of materials basis was performed to minimize the nega tive effect of building materials. As a result of optimization a 13.5% reduction of primary energy intensity, 3.7% reduction of global warming potential and 4.2% of acidification potential were achieved for the whole building by the change of building materials.

Selection of building materials in the design process is an important factor influencing not only future functionality of the building but also environmental performance. This paper deals with the environmental analysis of two material alternatives of one conventional Slovak masonry family-house with commonly used material composition in selected structures. Environmental analysis was aimed at the calculation of embodied energy, embodied CO 2 , and embodied SO 2 emissions expressed as primary energy intensity (PEI), global warming potential (GWP), and acidification potential (AP), respectively. Total embodied energy of building materials (PEI) has been calculated to be equal to 780.1 and 698.4 GJ for A1 and A2 alternatives. Average calculated values of environmental parameters reached 2.19 MJ/kg of used materials for PEI; 0.105 kg CO 2 eq/kg for GWP and 0.71 9 10 -3 kg SO 2 eq/kg for AP. Average values of building materials environmental parameters per floor area were calculated of 4,195.925 MJ/m 2 for embodied energy (PEI), 202.5 kg CO 2 eq/m 2 for embodied CO 2 emissions (GWP) and 1.36 kg SO 2 eq/m 2 for embodied SO 2 emissions (AP). The results of the analysis point to the fact that it is possible to reduce the environmental impacts by up to 61.0 % in particular structures and by up to 10.5 % overall just by a simple change of several building materials in the structures.

The work presents technologies of materials, energy and water management that can be used for sustainable buildings, reducing costs and environmental impacts. The aim was to encourage the reduction of energy consumption, adequate water management and more sustainable material choices in new or existing buildings. For this, a diagnosis of existing technologies and alternatives was carried out in the first stage of the work. The second stage consisted of analyzing among the technologies and alternatives diagnosed from the methodology which can be applied in a fictitious case study of housing, its implementation and maintenance and viability analyzing, finally, environmental indicators, social and economic. The results showed that the best evaluated technologies/alternatives were in Energy: ventilation and natural light; in Water Management: double-action sanitary basin, flow restrictors, aerators with constant flow, and minicistern systems; and in Materials: bamboo, wood, soil-cement brick, earth, steel frame and wood frame, aggregate with ash from rice husks, aggregate with ash from sugarcane bagasse, glass, phase change materials, aggregate with residues of construction and demolition, Portland cement and cement with blast furnace slag; which can be used in the civil construction sector, and provide socio-environmental and economic benefits, encouraging new studies and its use for public/private buildings, aid in the elaboration of public policies to reduce costs and improve the quality of buildings.

Building industry has leading position in deterioration of environment. Therefore environmental assessment of building materials is very important. Life Cycle Assessment is the most complex method for quantifying of environmental impact and performing optimization. A single-family residential house was selected for evaluation and optimization of building materials, as presented in this paper. Building materials were divided into 10 groups of structures on the basis of calculation tool of Createrra. Contribution of building and particular structures in terms of used materials was enumerated. The highest contribution to global warming (GWP = 17770.5 kg CO2eq), acidification (AP = 57.2 kg SO2eq) and the highest consumption of primal energy (PEI = 153 350.4 MJ) was calculated for materials used in foundations. Some structures were selected for further material optimization to minimize their negative impact. It was proven that the proper selection of materials can lead to minimizing of t...

The term "passive house" refers to rigorous and voluntary standards for energy efficiency in a building, reducing its ecological footprint. There are many ways how to build a passive house successfully. These designs as well as construction techniques vary from ordinary timber constructions using packs of straw or constructions of clay. This paper aims to quantify environmental quality of external walls in a passive house, which are made of a timber frame, lightweight concrete blocks and sand-lime bricks in order to determine whether this constructional form provides improved environmental performance. Furthermore, this paper assesses potential benefit of energy savings at heating of houses in which their external walls are made of these three material alternatives. A twostorey residential passive house, with floorage of 170.6 m 2 , was evaluated. Some measurements of air and surface temperatures were done as a calibration etalon for a method of simulation.

Life Cycle Analysis of Single Family Houses and Effects of Green Technologies on Environment
Innovations-Sustainability-Modernity-Openness Conference (ISMO’19), 2019
Construction and using of buildings for many years produce long-lasting impacts on human health and the environment. Life cycle assessment (LCA) is the rapidly evolving science of clarifying these impacts in terms of their quality, severity, and duration. LCA of three selected new family houses located in Eastern Slovakia is performed with the aim to compare them in terms of built-in materials as well as used technologies. The main goal of the analysis is to investigate and underline the foreseeable reduction rate of environmental impacts resulting from applied green materials and green technologies. LCA impact categories of global warming potential (GWP), ozone depletion potential (ODP), acidification potential (AP), eutrophication potential (EP), and photochemical ozone creation potential (POCP) are selected for this analysis. Investigated family houses are built from conventional materials, such as aerated concrete blocks, reinforced concrete, thermal insulation of silicate miner...
