Ecodesign has gained significant traction in recent years ranging from academic research to business applications at a global scale. Initial emphasis on the environmental aspect of design has evolved to include economic and social aspects, with projects ranging from small-scale products to large-scale industrial systems. In this paper, the authors re-analyse 10 of their major ecodesign research projects of the past ten years to identify five categories of challenges and promising future directions for ecodesign research. This paper is primarily a retrospective position paper based on the authors’ experience of actual design studies, providing also a relevant literature review and summary of design practices.

This research set out to identify and structure from online reviews the words and expressions related to customers' likes and dislikes to guide product development. Previous methods were mainly focused on product features. However, reviewers express their preference not only on product features. In this paper, based on an extensive literature review in design science, the authors propose a summarization model containing multiples aspects of user preference, such as product affordances, emotions, usage conditions. Meanwhile, the linguistic patterns describing these aspects of preference are discovered and drafted as annotation guidelines. A case study demonstrates that with the proposed model and the annotation guidelines, human annotators can structure the online reviews with high inter-agreement. As high inter-agreement human annotation results are essential for automatizing the online review summarization process with the natural language processing, this study provides materials for the future study of automatization.

This research set out to identify and structure the words and expressions related to customers’ likes and dislikes found in online reviews on order to guide product development. Previous methods have mainly focused on product features, yet reviewers express preferences on much more. Here we build on an extensive review of the design science literature to propose a summarization model containing multiple aspects of user preference, such as product affordances, emotions, and usage conditions. We also uncover the linguistic patterns describing these aspects of preference, and draft them into annotation guidelines. A case study demonstrates that our proposed model and annotation guidelines enable human annotators to structure the online reviews with high inter-agreement. As high inter-rater-agreement human annotation results are an essential step towards automating the online review summarization process with natural language processing, this study brings material for future automatization research.

Customers post online reviews at any time. With the timestamp of online reviews, they can be regarded as a flow of information. With this characteristic, designers can capture the changes in customer feedback to help set up product improvement strategies. Here, we propose an approach for capturing changes in user expectation on product affordances based on the online reviews for two generations of products. First, the approach uses a rule-based natural language processing method to automatically identify and structure product affordances from review text. Then, inspired by the Kano model which classifies preferences of product attributes in five categories, conjoint analysis is used to quantitatively categorize the structured affordances. Finally, changes in user expectation can be found by applying the conjoint analysis on the online reviews posted for two successive generations of products. A case study based on the online reviews of Kindle e-readers downloaded from amazon.com shows that designers can use our proposed approach to evaluate their product improvement strategies for previous products and develop new product improvement strategies for future products.

The residential building is a major energy consumer and pollution source worldwide. The shift towards constructing energy-efficient buildings is impelling higher performance. In sustainable building, occupants become a major source of uncertainty in energy consumption. Yet, energy simulation tools often account for occupant behaviour through predefined fixed consumption profiles. Therefore, energy and buildings experts are in need for more precise methods for better forecasting the influence of occupants on the building performance. An activity-based framework for quantifying occupant-related energy consumption is proposed. The energy consumption is quantified per domestic activity as a function of households’ socio-demographic and economic attributes. The aggregation of such domestic activity energy consumption provides an accurate estimation of the household energy consumption per daily, monthly and annually periods. First, a literature review about residential energy consumption and the existing modelling approaches is presented. Second, a systematic breakdown structure of energy end-uses is proposed. The activity-based framework is then introduced. An application example is demonstrated together with simulation results. Finally, model’s utility is outlined and its possible implications are discussed.

International audienceWith 270 million light vehicles and 20 million heavy-duty and off-road (HDOR) vehicles in use in the European Union, the automotive and HDOR industries form two major sectors of the European economy. Each year, 12 million light vehicles plus 1 million HDOR vehicles reach the end of their lives. In a circular economy perspective, the following two questions are of growing concern: (i) to what extent is the circular economy achieved and implemented in the automotive and HDOR sectors? (ii) what industrial practices and regulations are prevalent and commendable for the circular economy? The end-of-life management of light vehicles (subject to the ELV Directive 2000/53/EC) has been widely studied in the literature, but the end-of-life stage of HDOR vehicles has long been neglected by researchers. To fill this gap, both extensive literature survey and in-depth industrial investigations were conducted. Key factors, i.e. regulations, business models and market evolution, and integration of new emerging technologies affecting the circular economy performance of the automotive and HDOR sectors were analysed. Lessons learned from best industrial practices are highlighted, and remaining challenges for a more circular economy are identified. The two industries are compared in terms of the four buildings blocks of the circular economy and the four possible feedback loops defined by the Ellen MacArthur Foundation. This research contribution can lead on to practical applications, e.g. help industrial practitioners and policy makers take up the challenges and seize opportunities to close the loops for HDOR vehicles through different approaches

Life Cycle Assessment (LCA) assesses the environmental performance of products through their entire life cycle. LCA-based decision-making usually focuses on environmental impact, omitting other considerations, such as customer expectations and economic aspects. Although the environmental performances of industrial systems are highly dependent on operating conditions (e.g. local context, accessibility of resources), LCA usually integrates generic data. The aim of this chapter is to provide an integrated framework to identify the solutions best suited to a specific context, considering environmental, economic and commercial aspects. First, the environmental performances of competing products are compared using LCA. A scenario-based approach is then applied based on the most influential parameters identified in the environmental assessment. Costs are then incorporated into a set of exploitation scenarios. Second, several customer profiles are generated with respect to their economic and environmental strategies. Products are then ranked according to these profiles. The final step is to identify the most suitable solution for a given context-client couple. The framework is applied to three burners for forge furnaces. Results demonstrate that client profiles and operating contexts (namely client expectations, location and resource availability and costs) affect technological choices.

Autonomous Vehicles (AV) are the future evolution of Land Transportation Systems (LTS). They promise an improvement in road safety. However, safety requirements stay a big challenge for their development. The literature presents a lack of insight on the way LTS safety requirements will evolve. This paper proposes an analysis method of LTS safety requirements evolution toward AV. The ASIL metric is used to evaluate the safety criticality. The application on two case studies, the steering by wire and platooning systems, results in a better understanding and characterization of this evolution.

International audienceIn this article, a usage-driven perspective is taken to analyze the lack of industrial uptake of ecodesign tools in the construction sector. Eleven interviews with professionals were carried out to gain insight into the building design process, the roles of the different actors and their interactions. Nineteen further interviews investigated ecodesign knowledge and practice, and the barriers to wider implementation of this approach. The data drawn from the interviews were analyzed with the Dependency Structure Modelling Value Bucket (DSM VB) algorithm. The algorithm maps usage situations, designer issues and existing ecodesign tools to highlight gaps in the available offer for ecodesign tools. It appears that ecodesign tools are missing in the early design stages, and that what is most needed in these phases are tools for multicriteria analysis (economic, social, and environmental) and benchmarking. Tools answering these needs, combined with desirable changes we identified in the design process, would help ecodesign adoption

Assessing product circularity performance is not straightforward. Meanwhile, it gains increasingly importance for businesses and industrial practitioners who are willing to effectively take benefits from circular economy promises. Thus, providing methods and tools to evaluate then enhance product performance—in the light of circular economy—becomes a significant but still barely addressed topic. Following a joint agreement on the need to measure product circularity performance, this paper provides an overview of mechanisms aiming to help industrial practitioners in this task. In fact, three existing approaches to measure product circularity performance have been tested on an industrial case study and criticized regarding both their applicability in industry and their accordance with circular economy principles. Although these methods and tools deliver a first and rapid trend of product circularity performance, the whole complexity of circular economy paradigm is far from being considered. In addition, operational guidance for engineers, designers or managers to improve their products in a circular economy context are missing. As a result, both recommendations for industrial practitioners and guidelines for the design and development of new frameworks, tools and indicators aiming at measuring product circularity performance are provided. This includes cornerstones, key requirements and practical implications to support enhanced circularity measurement that will be developed in further work, accordingly to circular economy paradigm and industrial reality.

The French network Eco-design of Sustainable Systems (EcoSD) has initiated collaborative research projects in order to foster collaborations between academic and industrial partners. Two projects concerning eco-innovation processes, methods and tools have been carried out between 2012 and 2014. This paper first offers a synthesis of the projects, and questions the new directions to feed research in eco-innovation for the forthcoming years. The first project concerned the perception of eco-innovation by companies. It aimed at defining the features and goals of eco-innovation compared to eco-design through a survey with 12 French industrial partners. Results confirm that eco-innovation still is an emerging topic and does not seem to be supported by any structured process. The second project made a focus on the stage of eco-evaluation and eco-selection of the most promising ideas. In order to understand the emergence of ideas with a high environmental potential, three groups of mixed academics and industrials were asked to test two methods involving mapping, selection, combination and environmental evaluation of ideas. Main results show that there is a large inter-group variability in the evaluation of the environmental potential of ideas. Lastly, three interlinked directions for research in eco-innovation are identified. The first direction deals with the eco-ideation phase, where appropriate stimulation mechanisms should be integrated to. The second direction deals with the environmental evaluation of ideas very early in the process. It is necessary to characterize the inputs and outputs from this phase, building a bridge towards a latter simplified environmental assessment. The last direction deals with the construction of an efficient eco-innovation process based on the two previous phases. The challenge is to reduce the gap between academia and industry, enabling companies to introduce an eco-innovation process into their current design process.

International audienceEco-innovation methodologies and tools are being applied in companies to an increasing extent. None of them, however, are particularly adapted to complex systems industries, where the eco-design requirements are highly specific. These systems are characterized by large size and mass, and relatively long and uncertain life cycles. The associated organization is also complex as there are multiple highly specialized experts, who rarely collaborate, and much less so on environmental aspects. In this paper, an adapted eco-innovation process based on the eco-design strategy wheel is proposed for use with a working group of internal technical experts. A first phase involves generating a high number of potential eco-innovative R&D projects that are then analyzed and assessed using an appropriate multi-criteria grid. Three structured filters enable an informed selection of the most promising projects that will then make up a balanced R&D project portfolio. The whole process has been successfully applied at Alstom Grid on large electrical stations used in the primary aluminium industry

With the emergence of environmental legislations in many countries, the importance placed upon environmental protection has been raised to a new level, especially for industrial activities. Considering environmental issues as early as possible, starting with the design stage, is expected in order to better manage and diminish adverse environmental impact. Commensurate progress has been made in method/tool development for use in environmental impact estimation; however, very few of these methods allow integrating this estimation early in the design process—a critical point of deciding for potential product concepts and suppliers. In this paper, we propose a tool that integrates environmental impact estimation into architecture and supplier identification, in order to conjointly consider requirements satisfaction as well as uncertainty due to new module and new supplier integration. This tool is developed to support original equipment manufacturer decision making in the context of an extended enterprise. A case study is presented to illustrate a plausible implementation.

Occupants' behavior exerts a significant influence on the energy performance of residential buildings. Industrial energy simulation tools often account for occupants' as monolithic elements with standard averaged energy consumption profiles. Predictions yielded by these tools can thus deviate dramatically from reality. This paper proposes an activity-based model for forecasting energy and water consumption of households and discusses how such an occupant-focused model may integrate a user-focused design of residential buildings. A literature review is first presented followed by a brief recall of the proposed modeling methodology and a sample of simulation results. The possible integration of the proposed model into the design and energy management processes of residential buildings is then demonstrated through a number of use cases.

Life Cycle Assessment (LCA) is a methodology to assess environmental performances of products throughout their life cycles. Traditionally, LCA-based decision-making focuses on environmental impacts, excluding customer expectations and economic considerations. Moreover, it usually uses generic data while environmental performances of industrial systems often depend on local contexts. The aim of this paper is to provide a comprehensive framework to identify the solution most adapted to a specific context, considering environmental, economic and commercial aspects. First, environmental performances of competing products are compared thanks to LCA. A sensitivity analysis highlights influential parameters on which operational scenarios are built. Costs are then incorporated into a set of exploitation scenarios. Second, matrix-based approach is used. Products are ranked according to several client profiles. The most suitable solution for a given context is identified. This framework is applied on three burners for forge furnaces. Results show that client profiles and operational contexts (namely client expectations, location and resources availability and costs) affect choices.

Building occupants are considered as a major source of uncertainty in energy modeling nowadays. Yet, industrial energy simulation tools often account for occupant behavior through some predefined scenarios and fixed consumption profiles which yield to unrealistic and inaccurate predictions. In this paper, a stochastic activity-based approach for forecasting occupant-related energy consumption in residential buildings is proposed. First, the model is exposed together with its different variables. Second, a direct application of the model on the domestic activity “washing laundry” is performed. A number of simulations are performed and their results are presented and discussed. Finally, the model is validated by confronting simulation results to real measured data.

International audienceReduction of packaging waste has been a European target for more than 40 years. However, packaging is indispensable for protecting what it carries. In this study, an analysis of the European regulations on packaging and of their resulting effect on recycling performance was performed by means of a literature survey and the national results published in the European Database, Eurostat. Based on these data, two series of five Life Cycle Assessments (corresponding to the national situation of five European countries: France, Germany, Italy, Spain, Sweden) were conducted on three olive packaging solutions: doypacks, glass jars and steel cans. The results highlight the influence of national household waste collection rates and selected technologies for waste treatment (recycling and incineration) on the environmental performance of packaging design. A qualitative analysis of user expectations by means of a questionnaire demonstrates that the environmentally better solution (doypack) was not aligned with user expectations. The loss of food introduced by the better packaging solution is also a reason to question its value. The authors conclude that it is important to increase waste collection rates and recycling in order to actually improve packaging sustainability.
