The presented study is focused on the verification of a Building Environmental Assessment System (BEAS). A total of 13 detached family houses representing typical construction sites in Slovakia were chosen for analysis, evaluation and certification by using a BEAS which contains several main fields: A—Site Selection and Project Planning; B—Building Construction; C—Indoor Environment; D—Energy Performance; E—Water Management; and F—Waste Management. The results of this study show that the current construction method for family houses does not respect the criteria of sustainable construction as much as it possibly can. The reason for this is that investment costs for construction are prioritized over environmental and social aspects. Therefore, one house with a score of 1.10 is certified as BEAS BRONZE, ten family houses with scores of 1.56–2.88 are certified as BEAS SILVER and only two family houses with total scores of 3.59 and 3.87, respectively, are certified as BEAS GOLD. The overall results show that the weakest fields of sustainability are Waste management, Energy performance and Building construction. The best-rated fields are Site Selection and Project Planning, Indoor Environment and Water Management. In the future, it is essential to pay attention to those areas where the sustainability criteria have not been reached, as well as to raise project teams’ awareness of sustainability issues and subsequently to transfer them to building practices.

This paper compares the sustainability aspects of three family houses according to the Slovak building environmental assessment system (BEAS). Various categories of family houses were evaluated, including site selection, project planning, building construction, indoor environment, energy performance, and water and waste management. Based on the results, Family Houses 3 and 2 are certified as BEAS SILVER, with scores of 2.46 and 2.01, respectively. Family House 1 is certified as BEAS BRONZE, with an overall score of 1.44. The results show, not only the importance of the site in terms of availability, connectivity to the network and the potential to use renewable energy sources, but also the importance of the design and construction of the building, including the application of environmentally friendly building materials, ensuring the quality of the indoor environment and the energy efficiency of the building. The aims of this study were to highlight the current trend in the design and construction of low-rise residential family houses in Slovakia and to identify gaps in the design and construction of key sustainability aspects through the existing building environmental assessment system. In the future, many low-rise residential family houses will be assessed to modify and validate BEAS.

Currently, we are witnessing the significant impact of industrial activity on the environment. A recent study shows that construction is the third largest industry sector in terms of environmental pollution. One option to reduce these negative effects is environmental assessment of buildings, as well as the used building materials. One of the most comprehensive environmental assessment methods is LCA (Life Cycle Assessment), which includes the assessment of impacts within mode ”Cradle-to-gate” which is focused on assessment of a partial product life cycle from resource extraction (cradle) to the factory gate (i.e., before it is transported to the consumer). The aim of this paper is a comparison of the environmental impact of selected material variants applied within modern methods of construction. The comparison will be processed through the results of the case study containing three material variants of family houses construction in term of three selected parameters - embodied energy, global warming potential and acidification potential.

Abstract Building activity has recently led to the deterioration of environment and has become unsustainable. Several strategies have been introduced in order to minimize consumption of energy and resulting CO2 emissions having their origin in the operational phase. But also other stages of Life Cycle should are important to identify the overall environmental impact of construction sector. In this paper 5 similar Slovak buildings (family houses) were analyzed in terms of environmental performance of building materials used for their structures. Evaluation included the weight of used materials, embodied energy and embodied CO2 and SO2 emissions. Analysis has proven that the selection of building materials is an important factor which influences the environmental profile. Findings of the case study indicated that materials like concrete, ceramic or thermal insulation materials based on polystyrene and mineral wool are ones with the most negative environmental impact.

Numerous scientific researches show that the activities connected with building materials produce significant negative environmental effects. Observed from the point of architecture, the use of building materials is found to be one of the critical factors of environmental pollution and degradation. The purpose of introducing architectural interventions, including proper selection, is the reduction of the negative environmental impact of building materials. The aim of this paper is to define, from the ecological aspect, basic principles for the selection of building materials. First, principles were defined through the all - inclusive analysis of every phase in the life cycle of building materials. Summing categories: embodied energy and embodied CO2 are discussed afterwards. In the order to simplify the procedure of arriving at a decision, priorities in selection were emphasized in every separate segment of this paper. The selection of building materials with reduced negative environmental impact (ecologically correct building materials) is one of the key decisions in the process of designing ecologically correct buildings.

This study aims to develop a methodology for the selection of sustainable building materials for the reduction of embodied and operational energy for a complex infrastructure transportation project, i.e., elevated metro rail station of Ahmedabad, India by application of building information modelling (BIM) and factor comparison method (FCM). Evaluation of the alternative building materials and designs to obtain the best energy efficiency has been carried out using Revit Architecture 2018 and Green Building Studio. The achieved average embodied energy savings is about 73%, which is by the suggested alternative materials instead of existing ones. By application of FCM, which is a multi-criteria decision making (MCDM) technique, it has been observed that the polished Kota-stone flooring, stone-floor tile cladding, toughened fibre-glass ceiling and insulated fibre-glass door appear to be the most feasible sustainable material for flooring, wall cladding, ceiling, openings and fenestrations for the design of the metro rail station box in Ahmedabad, India. This study contributes significant knowledge in the field by highlighting the application of BIM as a tool for sustainable development and recommends a few alternate building materials and sustainable designs which would result in the reduction of energy usage for the metro-rail-station and other building structures leading to a sustainable future.

Energy is a key issue for Portugal, it is responsible for the higher part of its imports and since almost 30% of Portuguese energy is generated in power stations it is also responsible for high CO2 emissions. Between 1995 and 2005 Portuguese GNP rise 28%, however the imported energy in the same period increased 400%, from 1500 million to 5500 million dollars. As to the period between 2005 and 2007 the energy imports reach about 10,000 million dollars. Although recent and strong investments in renewable energy, Portugal continue to import energy and fossil fuels. This question is very relevant since a major part of the energy produced in Portugal is generated in power plants thus emitting greenhouse gases (GHGs). Therefore, investigations that could minimize energy use are needed. This paper presents a case study of a 97 apartment-type building (27.647 m2) located in Portugal, concerning both embodied energy as well as operational energy (heating, hot water, electricity). The operational energy was an average of 187,2 MJ/m2/yr and the embodied energy accounts for aprox. 2372 MJ/m2, representing just 25,3% of the former for a service life of 50 years. Since Portuguese energy efficiency building regulation made under the Energy Performance Building Directive (2002/91/EC-EPBD) will lead to a major decrease of operational energy this means that the energy required for the manufacturing of building materials could represent in a near future almost 400% of operational energy. Replacement up to 75% of Portland cement with mineral admixtures could allow energy savings needed to operate a very high efficient 97 apartment-type building during 50 years.

The Impact

The largest of CO2 emissions on earth derives from construction activities. It is necessary to solve the problem to reduce the impact of CO2 emissions. One of the solution to reduce the impact of CO2 emission because of construction activity is using re-used material for building construction, such as re-used shipping container because the re-used material has low embodied energy. This paper has three purposes, and there are: explaining the application of re-used containers as building materials in the context of green architecture, explaining the application of building design using re-used containers as material, and explaining the advantages and disadvantages of used containers as building materials. Creative Hub ITSB as a case study owned by the campus of ITSB. The building construction consists of 20 units of a re-used container (20 feet size). The prefabrication construction uses for each steel material. Each component of the building assembled in the workshop, then it delivered to site by truck. The main issues that need to be solved are a matter of the delivery system, the structure, and joints, and the component assembly. Cross-ventilation system and insulating material also crucial because it can reduce building temperature.

Strategic Environmental Assessment (SEA) is a process used for the evaluation of environmental impacts at a higher level of decision-making than that of each individual project, i.e., during the preparation and implementation of policies, programs, and plans, with the objective of incorporating the aspect of sustainable development in the early stages of planning. However, the “strategic” nature of SEA is the cause of frequent confusion among the responsible competent institutions and professionals regarding the selection of the most appropriate methods and techniques for each individual situation. At the international level, current research indicates a certain ambiguity in the use of methods and techniques in every step of SEA processes. In Greece, despite the implementation of SEA procedures in the preparation of a number of plans and programs after the transposal of the SEA Directive, to date, no attempt has been made to systematize the current experience and practice from the utilization of methods and techniques. The objective of the present study is to analyze and provide a comparative evaluation of the Greek and international experience, on the one hand with the systematic examination of Strategic Environmental Impact Assessments, and on the other with primary research, through questionnaires addressed to Greek practitioners. An important observation is that, both in Greece and abroad, there are inadequacies in the existence and/or the use of guidance manuals for the selection of the most appropriate methods and techniques, and only a limited range of methods and techniques are used in comparison with those catalogued in international literature.
