Infrastructure projects, which include a wide range of construction and energy projects, play an important role amid other industrial projects. In this regard, petroleum refinery industry projects are one of the leading manufacturing industries in the world and have the most notable position in the energy industry projects. Developing petroleum refinery industry projects are one of the principal contributors to economic and social development. In spite of the necessity of country development, this development has to be sustained at least in economic, social, and environmental matters (pillars of sustainable development) particularly after the Brundtland Commission Report in 1987. In this paper, it is proposed to simplify the evaluation process of life cycle sustainability versus life cycle stages. Thus, an indicator-based approach is used in order to evaluate the sustainability along different stages of petroleum refinery industry projects. Also, a multi-level hierarchy of criteria decision making is defined by using Analytic Hierarchy Process (AHP), combined with a fuzzy set theory to enhance the reliability of the results. The outputs of this paper will be helpful for decision makers in many ways such as the most important stage with regard to sustainable development matters; or the most important pillars (economic, social, and environmental) of sustainability in each life cycle stage. Also, other valuable outputs based on the results are consequently discussed.

Vertical Greening

Urban greening provides a wide range of ecosystem services to address the main challenges of urban areas, e.g., carbon sequestration, evapotranspiration and shade, thermal insulation, and pollution control. This study evaluates the environmental sustainability of a vertical greening system (VGS) built in 2014 in Italy, for which extensive monitoring activities were implemented. The life-cycle assessment methodology was applied to quantify the water–energy–climate nexus of the VGS for 1 m2 of the building’s wall surface. Six different scenarios were modelled according to three different end-of-life scenarios and two different useful lifetime scenarios (10 and 25 years). The environmental impact of global-warming potential and generated energy consumption during the use phase in the VGS scenarios were reduced by 56% in relation to the baseline scenario (wall without VGS), and showed improved environmental performance throughout the complete life cycle. However, the water-scarcity index (WSI) of the VGS scenarios increased by 42%. This study confirms that the installation of VGSs offers a relevant environmental benefit in terms of greenhouse-gas emissions and energy consumption; however, increased water consumption in the use phase may limit the large-scale application of VGSs.

Most of the definitions of sustainability include three basic pillars: economic, environmental, and social. The economic pillar has always been evaluated but not necessarily in the sense of economic sustainability. On the other hand, the environmental pillar is increasingly being considered, while the social pillar is weakly developed. Focusing on the environmental and social pillars, the use of methodologies to allow a wide assessment of these pillars and the integration of the assessment in a few understandable indicators is crucial. This article is structured into two parts. In the first part, a review of life cycle impact assessment methods, which allow a comprehensive assessment of the environmental and social pillars, is carried out. In the second part, a complete environmental and social sustainability assessment is made using the ecoinvent database and ReCiPe method, for the environmental pillar, and SOCA database and simple Social Impact Weighting method, for the social pillar. This methodology was used to compare three optimized bridges: two box-section post-tensioned concrete road bridges with a variety of initial and maintenance characteristics, and a pre-stressed concrete precast bridge. The results show that there is a high interrelation between the environmental and social impact for each life cycle stage.

Enterprise sustainable development emphasizes coordination of the development of economy, environment and society. The life cycle cost based on the sustainable development controls the engineering cost as well as environmental pollution and damage. The thermal power plant burns large amount of fossil fuels and discharge pollutants which cause serious pollution. Therefore the pollution control and ecological conservation make up important parts of construction and production cost, both of which are key parts of life cycle cost. This paper uses analytic hierarchy process and fuzzy comprehensive evaluation to estimate the life cycle cost and helps the enterprise to make social or temporal comparison and potentiality exploitation and to improve its sustainable development capability.

System Sustainability

The sustainable development of energy systems does not only involve the use of renewable energy resources but the increase in their efficiency as well, enabling society to maximise the benefits of their consumption. The production of electrical energy from clean and renewable sources contributes to lowered fossil fuel exploitation and the reduction of its damaging effect on the environment. This is a way to reach the global target of sustainable development - striking a balance between resource consumption and the achievable natural cycle regeneration. Environmental protection is in the focus of attention. Namely, when energy system sustainability is assessed, in addition to the ecological sustainability assessment (based on life cycle analysis - LCA), attention should be paid to the decrease in energy quality in energy processes (exergy loss). This paper presents the thermodynamic approach to energy system sustainability assessment by applying life cycle exergy analysis (LCEA). The key issue is the assessment of systems which use sustainable energy sources: the wind turbine and the stand-alone photovoltaic solar system.

Social Life Cycle Assessment

As sustainable development has emerged as a priority on the international agenda, increasing emphasis has been placed on “Life Cycle Sustainability Assessment (LCSA),” wherein environmental, economic, and social performance are comprehensively integrated. This study, as part of an LCSA approach, uses Social Life Cycle Assessment (S-LCA) to analyze the worker category social impact for concrete plants in South Korea. For the analysis, three types of concrete plant with different operating systems were selected and evaluated: Direct operation, operated by dedicated concrete manufacturers, and operated by cement suppliers. Eleven major social topics, which were mentioned in the international standards and international institutes, were selected as the subjects of evaluation; the social impacts were evaluated by applying the evaluative criteria for social topics presented in the Handbook for Product Social Life Cycle Assessment of PRé Sustainability. We determined that the highest social impact was found in concrete plants operated by cement suppliers (0.77), followed by plants operated by dedicated concrete manufacturers (0.50), and finally by plants with direct operations (0.09). These results can be applied by concrete plants to improve worker category areas in which they are lacking and by future researchers to evaluate the sustainable development of a variety of industries.

In recent years, it has been observed that disclosure of information leads to the risk. Without restrict the accessibility of information providing security is difficult. So, there is a demand of time to fill the gap between security and accessibility of information. In fact, security tools should be usable for improving the security as well as the accessibility of information. Though security and accessibility are not related directly, but some of their factors indirectly affect each other. Attributes play an important role in connecting the gap among security and accessibility. In this paper, finds the main attributes of security and accessibility that impact directly and indirectly each other such as confidentiality, integrity and availability and severity. The significance of every attribute in terms of their weight is important for their effect on the overall security during the big data security life cycle process. To calculate proposed work, researchers used the Fuzzy Analytic Hierarchy Process (Fuzzy AHP).
