“…From an economic point of view, the LLF (or maintenance factor [24]) is used to define the installation process and the maintenance operation for indoor workplaces. It is directly linked to the cost of lighting, and will facilitate the identification of consequences and indirect impacts in the intersection of LCA and life cycle cost [31]. From a human point of view, Section 3.2 explains that the perception of lumen depreciation by humans could lead to a decrease in the real useful lifetime of lamps.…”

Life Cycle Assessment of Lighting Systems and Light Loss Factor: A Case Study for Indoor Workplaces in France

et al. 2019

Life cycle assessment (LCA) methodology has been used to evaluate the performance of the following lighting systems: compact fluorescent lamps (CFL), light-emitting diode (LED) lamps, and fluorescent tubes (T5 type). This work covers the singularity of the French electricity mix for indoor workplaces lighting and describes the best strategy for lamp replacement. We have defined the light loss factor to integrate the following additional parameters: lumen depreciation, dirt accumulation, and risks of failure. Therefore, we propose a new definition of the functional unit (maintained megalumen hour), and we conduct this assessment to be compliant with the standards of lighting system equipment (NF EN 12464-1). Unlike previous studies, we observed that the manufacturing phase is the most impacting over the whole life cycle, thus making the extension of LED lamps’ lifetime a more effective strategy to reduce the potential environmental impacts than increasing their efficacy. This paper highlights how the light loss factor affects the LCA results and proves that it should be taken into account for subsequent assessments. Finally, this new approach includes the real usage of the lamps in the study and contributes to lay the foundation for life cycle sustainability assessment to also evaluate the economic, social, and human impacts of lighting.

“…Social life-cycle assessment (S-LCA) is "a technique for collecting, analyzing and communicating information about the social conditions and impacts associated with production and consumption" [1] (p. 6974). S-LCA focuses on current and potential (positive and negative) socio-economic impacts of processes, products, and services throughout their full life cycle [2] The ultimate goal of conducting S-LCA is to provide decision-making support after evaluating changes 2 of 25 in the lives of workers, consumers, society, and other key stakeholders related to the product's life cycle. S-LCA helps decision-makers to choose the alternatives with the most favorable social consequences.…”

Social Life-Cycle Assessment: A Review by Bibliometric Analysis

et al. 2020

This study examined the literature on social life-cycle assessment (S-LCA) published in the last 15 years (2003–2018) using bibliometric methods. Applying scientific mapping and analyzing publication performance, the study describes the structure of and trends in S-LCA publications in terms of related subject categories, authors, journals, countries, and highly cited articles. Challenges and research gaps in the S-LCA literature were also explored. The content of related papers published in the ISI Web of Science databases was examined to identify the main themes investigated, evolution of publication activity, and most representative elements. Analyses were conducted with SciMAT software. This tool enables researchers to map research specialties by extracting qualitative information in the specialized literature and representing it using quantitative measures. The results show rapid and exponential growth of the S-LCA research line in the past ten years, with a clear upward trend in related publications (mostly case studies), especially after publication of the UNEP/SETAC Guidelines for Social Life Cycle Assessment of Products in 2009: 66% of all articles published on S-LCA were published during the period 2015–2018, primarily by European authors. The findings also delineate S-LCA as a highly fragmented research field that has been applied to diverse sectors (agriculture, bioenergy, transport, water management, chemical products, electronics, etc.), mainly in non-European countries. Critical questions concerning methods, framework, paradigms, and indicators remain to be resolved. This study provides insight into the publication performance of S-LCA, characterizing its intellectual structure and salient authors and works. In identifying hotspots in the S-LCA research, the study provides a useful state-of-the-art reference guide for academics and reveals critical research gaps and potential research avenues for future studies to advance in consolidating the discipline.

“…Thanks to its complexity and flexibility, LCA can also be used for complex products, such as buildings [9]. The current challenges and possible future outlook of LCA were well described by Fauzi et al [10]. However, this application requires a great deal of time, high levels of expertise, and a large amount of data, which are sometimes difficult to access.…”

Recommendations for Developing a BIM for the Purpose of LCA in Green Building Certifications

et al. 2020

View full text Add to dashboard Cite

Building information modeling (BIM) and life cycle assessment (LCA) are two methods that can be helpful when designing buildings with lower environmental impacts. One of the most significant examples of environmental impact assessments in construction is green building certification. Certified buildings have improved performance and greater asset value. In this study, four certification systems were investigated for their potential interconnections with BIM and LCA. The main tasks were (1) to review a BIM-based workflow, (2) assess its usage as an input for the LCA within green certifications, and (3) provide suggestions for developing building models. Building models can be helpful during the design process, but the best results are expected when the specifically described steps are followed. These suggestions aim at improving building models in terms of their usage for green building certifications and particularly for LCA. All the investigated results were clarified and adjusted using a model of a recently finished building in Zug. As reference tools, One Click LCA and a manual process were selected. The outcomes were aligned with those of other studies and confirmed the necessity of good data and management quality for building projects.
