Life Cycle Assessment (LCA) aims to analyze possible impact upon manufacturing process and availability of products, and also study the environmental considerations and potential influence during entire life cycle ranging from procurement, production and utilization to treatment (namely, from cradle to tomb). Based on high‐density polyethylene (HDPE) pipe manufacturing of company A, this case study would involve evaluation of environmental influence during the production process. When the manufacturing process has been improved during “production process” and “forming cooling” stage, it is found that capital input on “electric power” and “water supply” could be reduced, thus helping to sharpen the competitive power of company A, and also ensure sustainable economic and industrial development in accordance with national policies on environmental protection.

The purpose of this paper is to present the durability analysis in predicting the reliability life cycle for an automobile crankshaft under random stress load using the stochastic process. Due to the limitations associated with the actual loading history obtained from the experimental analysis or due to the sensitivity of the strain gauge, the fatigue reliability life cycle assessment has lower accuracy and efficiency for fatigue life prediction.

The proposed Markov process embeds the actual maximum and minimum stresses by a continuous updating process for stress load history data. This is to reduce the large credible intervals and missing loading points used for fatigue life prediction. With the reduction and missing loading intervals, the accuracy of fatigue life prediction for the crankshaft was validated using the statistical correlation properties.

It was observed that fatigue reliability corresponded well by reporting the accuracy of 95–98 per cent with a mean squared error of 1.5–3 per cent for durability and mean cycle to failure. Hence, the proposed fatigue reliability assessment provides an accurate, efficient, fast and cost-effective durability analysis in contrast to costly and lengthy experimental techniques.

An important implication of this study is durability-based life cycle assessment by developing the reliability and hazard rate index under random stress loading using the stochastic technique in modeling for improving the sensitivity of the strain gauge.

The durability analysis is one of the fundamental attributes for the safe operation of any component, especially in the automotive industry. Focusing on safety, structural health monitoring aims at the quantification of the probability of failure under mixed mode loading. In practice, diverse types of protective barriers are placed as safeguards from the hazard posed by the system operation.

Durability analysis has the ability to deal with the longevity and dependability of parts, products and systems in any industry. More poignantly, it is about controlling risk whereby engineering incorporates a wide variety of analytical techniques designed to help engineers understand the failure modes and patterns of these parts, products and systems. This would enable the automotive industry to improve design and increase the life cycle with the durability assessment field focussing on product reliability and sustainability assurance.

The accuracy of the simulated fatigue life was statistically correlated with a 95 per cent boundary condition towards the actual fatigue through the validation process using finite element analysis. Furthermore, the embedded Markov process has high accuracy in generating synthetic load history for the fatigue life cycle assessment. More importantly, the fatigue reliability life cycle assessment can be performed with high accuracy and efficiency in assessing the integrity of the component regarding structural integrity.

Recently, there has been a shift toward the embodied energy assessment of buildings. However, the impact of material service life on the life-cycle embodied energy has received little attention. We aimed to address this knowledge gap, particularly in the context of the UAE and investigated the embodied energy associated with the use of concrete and other materials commonly used in residential buildings in the hot desert climate of the UAE.

Using input–output based hybrid analysis, we quantified the life-cycle embodied energy of a villa in the UAE with over 50 years of building life using the average, minimum, and maximum material service life values. Mathematical calculations were performed using MS Excel, and a detailed bill of quantities with >170 building materials and components of the villa were used for investigation.

For the base case, the initial embodied energy was 57% (7390.5 GJ), whereas the recurrent embodied energy was 43% (5,690 GJ) of the life-cycle embodied energy based on average material service life values. The proportion of the recurrent embodied energy with minimum material service life values was increased to 68% of the life-cycle embodied energy, while it dropped to 15% with maximum material service life values.

The findings provide new data to guide building construction in the UAE and show that recurrent embodied energy contributes significantly to life-cycle energy demand. Further, the study of material service life variations provides deeper insights into future building material specifications and management considerations for building maintenance.

The purpose of this study is to describe life cycle cost (LCC) and life cycle assessment (LCA) evaluation for single story building house in Malaysia. Two objective functions, namely, LCA and LCC, were evaluated for each design and a total of 20 alternatives were analyzed. Two wall schemes that have been adopted from two different recent studies toward mitigation of climate change require clarification in both life cycle objectives.

For this strategic life cycle assessment, Simapro 8.3 tool has been chosen over a 50-year life span. LCC analysis was also used to determine not only the most energy-efficient strategy, but also the most economically feasible one. A present value (PV)-based economic analysis takes LCC into account.

The results will appear in present value and LC carbon footprint saving, both individually and in combination with each other. Result of life cycle management shows that timber wall−wooden post and beam covered by steel stud (W5) and wood truss with concrete roof tiles (R1) released less carbon emission to atmosphere and have lower life cycle cost over their life span. W5R1 releases 35 per cent less CO₂ emission than the second best choice and costs 25 per cent less.

The indicator assessed was global warming, and as the focus was on GHG emissions, the focus of this study was mainly in the context of Malaysian construction, although the principles apply universally. The result would support the adoption of sustainable building for building sector.

In this paper, of exploratory character, the purpose of this paper is to propose the analysis of the life cycle for assessing the environmental, economic, and social impact in the activity of recovery, restoration, and valorization of Cultural Heritage.

The analysis protocol is applied to the case of recovery and restoration processes and then outlining the salient features of what may become a model of Cultural Heritage Life Cycle Management (CH-LCM).

The authors propose the approach of the life cycle, normally used to assess the impact of materials, processes or products, to the management of cultural heritage as an innovative methodology with great potential.

The methodology for this sector is highly innovative, especially in its interdisciplinary approach, through the use of different technical, historical, and economic skills which can provide the tools for the preparation of a management plan according to the logic of the life cycle.

The purpose of this paper is to identify the sustainability conditions of primary schools in Turkey within the scope of the life cycle assessment (LCA). It is aimed to develop optimum alternatives to reduce the environmental impact of primary schools and reach environmental sustainability targets of the sustainable development goals in Turkey.

From the construction project of 103 buildings located in Istanbul, 10 case buildings with various typical plans were chosen for analysis. The results regarding their life cycle energy and carbon emission for material production, operation and maintenance stages were calculated for a lifespan of 50 years. Results were evaluated and compared within the scope of environmental sustainability. Optimum alternatives for improving the environmental sustainability and performances of selected case buildings’ facades were developed, and the life cycle energy and carbon emission for proposed conditions were calculated. The obtained results were evaluated for current and proposed conditions.

Results showed that reinforced concrete material contributes the most to the life cycle-embodied energy and CO₂ emission of buildings. Cooling load increases the life cycle operational energy (LCOE) and CO₂ emission of buildings. Using high-performance glazing significantly reduces LCOE and CO₂ emission. Recycled and fiber-based materials have significant potential for reducing life cycle-embodied energy and CO₂ emission.

This study has been developed in response to achieving sustainable development targets on public buildings in Turkey. In this regard, external walls of primary schools were analyzed within the scope of LCA and recommendations were made to contribute to the policies and regulations requested by the Government of Turkey. This study proves that alternative and novel materials have great potential for achieving sustainable public buildings. The study answers to questions about reducing the environmental impact of primary school buildings by using LCA approach with a holistic point of view.

Environmental impact and changes are becoming essential in textile and yarn industries, where reliable measurement of parameters related to processing harmful substances needs to be examined. Such findings can be cumulated using smart assessment like life cycle analysis. The ecological impact category, supply chain, and climate-changing factors were considered for the necessary assessment.

This paper applies the Life Cycle Assessment technique in the textile and yarn industry to estimate critical environmental potentials. The critical input for the fabric and yarn industry was put in the GaBi software model to estimate various environmental potentials.

Global warming potential, electricity, and raw cotton consumption in the fabric and yarn industry were critical concerns where attention should be focused on minimizing environmental potentials from cradle to gate assessment.

This qualitative study is made via the industry case-wise inputs and outputs, which can vary with demographic conditions. Some machine and human constraints have not been implemented in modelling life cycle model for smart simulation. Smart simulation helps in linking different parameters and simulates their combined effects on the product life cycle.

This modelling approach will help access pollution constituents in different supply chain production processes and optimize them simultaneously.

The raw data used in this analysis are collected from an Indian small scale textile industry. In the textile fabrication industry, earlier assessments were carried out in cotton generation, impact of PET, cradle to grave assessment of textile products and garment processing only. In this research the smart model is drawn to consider each input parameter of yarn and textile fabric to determine the criticality of each input in this assessment. This article mainly talks about life cycle and circular supply assessment applied to first time for both cotton to yarn processing and yarn to fabric industry for necessary estimation of environment potentials.

Aims to investigate the contribution of life cycle assessment to global sustainability reporting of organizations.

Assesses the current state of global sustainability reporting and points out future trends of reporting within the three dimensions of economy, environment and society.

The internal and external communication of the corporate performance is a very important company way to sustainable development. The communication of the corporate performance comprises the strategic and operational goals, the corporate performance data on inventory level, the translation of the inventory data to sustainability core indicators as well as the performance evaluation in terms of sustainability. The future trends on policy level and in customer demands are moving towards a product‐related consideration of sustainability issues, the inclusion of indirect effects over the life cycle in addition to the site‐related effects of companies’ activities, the analysis of results on impact level as well as the automation of data administration.

The methodology of life cycle assessment (LCA) provides the main starting‐point for global sustainability reporting including the emerging future trends in this context. This paper shows that results of impact assessments as central parts of an LCA are a good basis for creating significant indicators for sustainability reports.

Enhancing sustainability of the supply process of construction materials is challenging and requires accounting for a variety of environmental and social impacts on top of the traditional, mostly economic, impacts associated with a particular decision involved in the management of the supply chain. The economic, environmental, and social impacts associated with various components of a typical supply chain are highly sensitive to project and market specific conditions. The purpose of this paper is to provide decision makers with a methodology to account for the systematic trade-offs between economic, environmental, and social impacts of supply decisions.

This paper proposes a novel framework for sustainability assessment of construction material supply chain decisions by taking advantage of the information made available by customized building information models (BIM) and a number of different databases required for assessment of life cycle impacts.

The framework addresses the hierarchy of decisions in the material supply process, which consists of four levels including material type, source of supply, supply chain structure, and mode of transport. The application is illustrated using a case study.

The proposed framework provides users with a decision-making method to select the most sustainable material alternative available for a building component and, thus, may be of great value to different parties involved in design and construction of a building. The multi-dimensional approach in selection process based on various economic, environmental, and social indicators as well as the life cycle perspective implemented through the proposed methodology advocates the life cycle thinking and the triple bottom line approach in sustainability. The familiarity of the new generation of engineers, architects, and contractors with this approach and its applications is essential to achieve sustainability in construction.

A decision-making model for supply of materials is proposed by integrating the BIM-enabled life cycle assessment into supply chain and project constraints management. The integration is achieved through addition of a series of attributes to typical BIM. The framework is supplemented by a multi-attribute decision-making module based on the technique for order preference by similarity to ideal solution to account for the trade-offs between different economic and environmental impacts associated with the supply decisions.

The US National Park Service (NPS) is responsible for the management of some of the most recognisable and notable natural and cultural resources in the USA. To make the case for additional maintenance funding, NPS is instituting life‐cycle cost management practices. Over the 50‐year life cycle of the Redwood Information Center at Redwood National and State Parks in Crescent City, California, custodial costs alone will sum to more than the total replacement construction cost for the entire facility. This point illustrates an important aspect regarding the true cost of operating and sustaining physical infrastructure over its life cycle. It also suggests that understanding life‐cycle costs is a critical element of effective, long‐term portfolio and asset management. Often, institutional owners of physical assets inadequately assess the true cost of building and owning facilities, typically overemphasising initial construction costs. Life‐cycle operations and maintenance (O&M) and capital renewal costs, however, almost always comprise a far greater percentage of total life‐cycle building costs. Using actual life‐cycle costs for an asset that is owned and managed by NPS, this paper explores the development of full life‐cycle costing, highlighting key life‐cycle cost drivers, of an information centre at the Redwood National and State Parks.
