Eco design implementation across the British product design industryRadlovic, Philippe January 2014 (has links)
Our understanding of the effects that human production and consumption has on our planet and its resources has challenged us to think differently when developing new products. In response to these problems, Eco Design has been developed over the last few decades. Eco Design is a process integrated into product and engineering design that aims to lower the environmental impact of products across their life cycle, whilst not hindering design brief criteria such as function, price, performance, and quality. Research in Eco Design has focused mainly on the development of new tools and ways to implement Eco Design in industry. However, there is still little empirical knowledge today regarding the state of Eco Design implementation and practices in industry; in addition to the prerequisite needs and factors to successfully implement Eco Design. The aim of this research has been to review the level and type of Eco Design in the British Product Design industry and to identify recurrent themes helping or hindering implementation. This was achieved through the use of a pilot study followed by a two stage case study design, involving 20 cases and 57 participants across 65 interviews. The investigation and its analysis produced 12 confirmed themes, each generating their own drivers and barriers to Eco Design implementation. This research into Eco Design implementation provides a unique contribution and a timely insight into the Eco Design practices of the British Product Design industry today. The research also provides the novel contribution of identifying the drivers and barriers to implementing and sustaining Eco Design, as well as an understanding of the strengths and shortfalls of the current Eco Design processes and tools. These contributions to knowledge in the field of Eco Design will help future research formulate better solutions to implement Eco Design processes in the Product Design industry.

Developing tools for sustainability management in the graphic arts industryEnroth, Maria January 2006 (has links)
The main aim of this thesis is to develop and test industry-specific, applied work procedures and tools for environmental and emerging sustainability work in the graphic arts industry. This includes methods to quantify, follow-up, evaluate, manage, improve and communicate the environmental performance of activities in the graphic arts supply chain and printed products. In order to achieve the aims of the thesis, a selection of work areas were chosen as the basis for developing the industry-specific work procedures and tools. The selected work areas are the following: environmental management (being a part of sustainability management), environmental and sustainability strategies, environmental indicators and design for environment (DfE). The research presented in this thesis was based on survey research methods, case studies and multi-company studies. Within the framework of these methods, quantitative and qualitative techniques for data gathering were used. The companies included in the studies were selected according to their willingness, interest and motivation to participate and develop their environmental or sustainability work. The most significant results of the research presented in this thesis regarding the selected work areas are the following: • An evaluation of early certified environmental management systems (EMSs) in Sweden identified four areas as priorities in making the EMSs more efficient. Two of them, viz. improvement in the follow-up of environmental work, and the linking of EMSs to product design, were developed for the graphic arts industry. The remaining two areas were clarifying the identification process and assessment of environmental aspects, and streamlining and co-ordinating different management systems. • An established and successfully tested working method for formulating and realising corporate sustainability strategies in the graphic arts industry. • Industry-specific environmental indicator models for the graphic arts industry with defined methods for standardised inventorying and calculations. These models have been tested, used and approved of by the industry itself. • Collected and compiled data for the developed environmental indicator models. Data have been collected from quite a large number of companies (10-20 companies for each of the printing techniques covered, i.e. coldset offset, heatset offset and gravure) over a period of several years. • The use of the industry-specific environmental indicator models was developed and illustrated. • A described and recommended work procedure for DfE in graphic arts companies including industry-specific tools for applying DfE to printed products, in the form of a manual and a checklist. The checklist was designed so that it can serve as a simple tool for the environmental assessment of printed products. The tools were tested by graphic arts companies. / <p>QC 20110124</p>

Assessing design strategies for improved life cycle environmental performance of vehiclesPoulikidou, Sofia January 2016 (has links)
Vehicle manufactures have adopted different strategies for improving the environmental performance of their fleet including lightweight design and alternative drivetrains such as EVs. Both strategies reduce energy during use but may result in a relative increase of the impact during other stages. To address this, a lifecycle approach is needed when vehicle design strategies are developed. The thesis explores the extent that such a lifecycle approach is adopted today and assesses the potential of these strategies to reduce the lifecycle impact of vehicles. Moreover it aims to contribute to method development for lifecycle considerations during product development and material selection. Current practices were explored in an empirical study with four vehicle manufacturers. The availability of tools for identifying, monitoring and assessing design strategies was explored in a literature review. The results of the empirical study showed that environmental considerations during product development often lack a lifecycle perspective. Regarding the use of tools a limited number of such tools were utilized systematically by the studied companies despite the numerous tools available in literature. The influence of new design strategies on the lifecycle environmental performance of vehicles was assessed in three case studies; two looking into lightweight design and one at EVs. Both strategies resulted in energy and GHG emissions savings though the impact during manufacturing increases due to the advanced materials used. Assumptions relating to the operating conditions of the vehicle e.g. lifetime distance or for EVs the carbon intensity of the energy mix, influence the level of this tradeoff. Despite its low share in terms of environmental impact EOL is important in the overall performance of vehicles. The thesis contributed to method development by suggesting a systematic approach for material selection. The approach combines material and environmental analysis tools thus increases the possibilities for lifecycle improvements while minimizing risk for sub-optimizations. / <p>QC 20160920</p>

Designing sustainable innovations : Opportunities for new life cycles within the furniture industryComacchio, Zeno January 2016 (has links)
The Linear Economy cannot any longer be sustained by the eco-system: virgin resources are limited and destined to terminate soon if the contemporary production and consumption model will be maintained. For this reason, in the last few years Circular Economy has become an increasingly discussed topic worldwide. Through the adoption of strategies that close-the-loop of the traditional linear production system, Circular Economy aims to find solutions that can create a balance between economy, society and environment. This study aims to provide a holistic overview on the main theories and strategies that can ease a business transition to a Circular Economy model, to analyse challenges and opportunities connected to this conversion and to present a concrete tool developed for this purpose. The Life Cycle Design theory is here discussed and contextualised within the furniture industry reality since this study has been executed in collaboration with IKEA, the company case study of this thesis. An academic and professional literature review have been performed in order to gather information about theory and practice related to the implementation of strategies needed by a Circular Economy: product disassembly, recovery, reuse, refurbish, recycle and remanufacturing. The professional literature reviewed point out that the implementation of a circular model can lead to economic advantages and growth’s opportunities for manufacturers in various economic sectors. The implementation of Circular Economy in the furniture industry seems to be in its early stages and it mainly focus, with few exception, on recycling rather than on the more effective reuse, refurbish or remanufacturing operations. This study points out the two main issues that the furniture manufacturers need to solve in order to enable the implementation of more effective circular strategies: product disassembly and recovery. Furthermore, the need of an innovative and holistic approach is discussed with particular emphasis on the importance of a systemic thinking that enable organisation to create their own identity and objectives in relation to the Circular Economy model. The importance of a system that connects and coordinate the sustainable efforts and aims for new products and services is therefore highlighted, suggested and deeply considered in the development of the tool proposed. To conclude, a comparison between two IKEA products (the sofas Söderhamn and Knopparp) was performed to identify the role of the products’ design and development in relation with the implementation of a Circular Economy model. The products were briefly technically analysed and then a comparison between a linear and a circular end-of-life cycle scenario has been represented.

Weight reduction of a connecting fitting used for frame assembly : A design optimization at IKEA Components AB / Viktreducering av ett beslag för rammontering : En designoptimering på IKEA Components ABSjöqvist, Emil, Johansson, David January 2019 (has links)
Continuous improvements are an integral part for the development of everyday life. These improvements do not only ascertain financial gain but also lessening the environmental impact. The purpose of this study is to gain a deeper understanding of the design process and the decisions required to achieve an optimal design with respect to weight reduction, while retaining the required strength. The study will also investigate the choice of material. This will be done through material and design studies, along with strength calculations of the product in question. The conclusion from this study is that it is possible to save a certain percentage of the material used, while keeping the strength, form, fit and function intact. The material study provided with a recommendation of the zinc alloy ZA-8. It is an alloy with a good combination of great strength, low density and price.

Miljöledning i produktutveckling : En studie i ISO 14001-certifierade företags produktutvecklingsprocesserNordström, Louise, Frost, Sandra January 2013 (has links)
Bakgrund: För att underlätta organisationers ansvarstagande gällande miljöpåverkan har standarder införts med syfte att ge stöd i utformning av miljöledningssystem. Ett vida använt verktyg är ISO 14001 vilken framhåller ständiga förbättringar i förhållande till den enskilda organisationens satta miljömål. På grund av standardens generella utformning är det upp till den enskilda organisationen att implementera denna på ett sätt som bäst passar verksamheten. Forskning pekar på att ISO 14001 innehar en ledande roll då det kommer till tillverkande företags miljöengagemang. Dock påvisar forskare att standarden inte är tillräcklig när det kommer till kommersiella produkters miljöpåverkan, men att företag som varit ISO 14001-certifierade en längre tid ändå i stor utsträckning arbetar systematiskt med denna aspekt. Syfte: Syftet med denna studie är att undersöka hur miljöhänsyn utformas och implementeras i ISO 14001-certifierade företags produktutveckling då man utifrån tidigare forskning kan anta att detta innebär organisationsspecifika varianter. Metod: För att uppfylla studiens syfte har fallstudier i fyra svenska företag genomförts. Dessa företag har representerats av personer vilka besitter ansvar gällande miljöaspekter i produktutvecklingsprocessen. Vidare har studien baserats på sekundärkällor. Teori: Den teoretiska referensramen består av forskning kring miljöledningssystem, ISO 14001 och design med miljöhänsyn samt Røviks översättningsteori. Slutsats: Studien visar på att företag har utvecklade system kring tillämpning av miljöhänsyn i produktutveckling. Dessa stammar från rutiner härledda från de miljömål som formulerats enligt ISO 14001. Vidare engageras personal som arbetar i anslutning till produktutveckling genom utbildningar i miljöfrågor och det enskilda företagets miljöpåverkan. / Background: To facilitate environmental responsibility among organisations, standards with the purpose to provide support in the implementation of environmental management systems have been introduced. A widely used tool is the ISO 14001-standard which highlights continual improvements in relation to the environmental goals of the specific organisation. Due to the generic design of the standard it is up to the organisation to implement it in a way that is most appropriate. Research shows that ISO 14001 makes a difference when it comes to the engagement for the environment of producing companies. However, scholars stress that the standard is not sufficient regarding commercial products, but also highlights findings which suggest that companies that have been ISO 14001-certified during a longer period of time in a greater extent have conducted systems that manage these aspects. Purpose: The aim of this study is to investigate how environmental responsibility is designed and implemented in the product development of ISO 14001-certified companies since one due to previous research can assume that this implies individual variances of the specific organization. Method: Case studies of four Swedish companies have been conducted in order to fulfill the aim of the study. These companies have been represented by individuals that possess positions concerning environmental aspects in the product development process. Additionally the study has been based on secondary sources. Theories: Research regarding environmental management systems, ISO 14001 and eco-design together with translation theory according to Røvik. Conclusion: The study shows that companies have developed systems regarding implementation of environmental aspects in their product development. These aspects derive from routines based on environmental goals formulated according to ISO 14001. Further, employees connected to the product development are educated in environmental aspects and the environmental impact of the individual company which accordingly affects the product development processes.

Moving Towards Sustainable and Resilient Smart Water Grids: Networked Sensing and Control Devices in the Urban Water SystemJanuary 2012 (has links)
abstract: Urban water systems face sustainability challenges ranging from water quality, leaks, over-use, energy consumption, and long-term supply concerns. Resiliency challenges include the capacity to respond to drought, managing pipe deterioration, responding to natural disasters, and preventing terrorism. One strategy to enhance sustainability and resiliency is the development and adoption of smart water grids. A smart water grid incorporates networked monitoring and control devices into its structure, which provides diverse, real-time information about the system, as well as enhanced control. Data provide input for modeling and analysis, which informs control decisions, allowing for improvement in sustainability and resiliency. While smart water grids hold much potential, there are also potential tradeoffs and adoption challenges. More publicly available cost-benefit analyses are needed, as well as system-level research and application, rather than the current focus on individual technologies. This thesis seeks to fill one of these gaps by analyzing the cost and environmental benefits of smart irrigation controllers. Smart irrigation controllers can save water by adapting watering schedules to climate and soil conditions. The potential benefit of smart irrigation controllers is particularly high in southwestern U.S. states, where the arid climate makes water scarcer and increases watering needs of landscapes. To inform the technology development process, a design for environment (DfE) method was developed, which overlays economic and environmental performance parameters under different operating conditions. This method is applied to characterize design goals for controller price and water savings that smart irrigation controllers must meet to yield life cycle carbon dioxide reductions and economic savings in southwestern U.S. states, accounting for regional variability in electricity and water prices and carbon overhead. Results from applying the model to smart irrigation controllers in the Southwest suggest that some areas are significantly easier to design for. / Dissertation/Thesis / M.S.

An Interactive Support For Developing Environmentally Friendly Product LifecyclesKota, Srinivas 01 1900 (has links) (PDF)
Products make substantial impact on environment. Design for Environment (DfE) is an approach to design where all the environmental impacts of a product are considered over entire products life. Since over 80% of the product costs are committed during the early stages, design can play a central role in reducing this environmental overloading by product. However, unlike cost and performance, use of environmental criteria and DfE is far from part of mainstream designing. Individual guidelines often exist for DfE but these are not integrated with design tools. There is a need for capture of the rationale in design process as a know how backup for later use.
Life Cycle Assessment (LCA) is currently the most promising and scientifically proven technique for estimating environmental impacts of a product during its lifecycle. Current LCA tools are not well integrated with design process and CAD tools. Consequently, there is a need for an LCA tool integrated into the natural design process that can be applied to early as well as detailed design stages. Detailed LCA is critically dependent on high volumes of product specific data, time consuming, often unaffordable and used after the detailed stages of design. Current approximate LCA methods are either incomplete, inaccurate or require prior knowledge of what data is important There is substantial uncertainty involved in the environmental impact calculations in LC. While Literature discusses uncertainty of impact data, there is no discussion on how to calculate and represent the total uncertainty in the potential impact of a product proposal at any given stage in design with respect to LCA.
There is a need for a method that can aid in decision making by supporting quantitative comparison of available alternatives to identify the best alternative, under uncertain information about alternatives. Often the likely performance, cost or environmental impacts of a product proposal could be estimated only with certain confidence, which may vary from one proposal to another. The overall objective of this thesis is to “Develop a support to the designers using which they can develop environmentally friendly product lifecycles in much the same way as they currently design products, at all stages of their design, while reusing information from their past design activities”. For this the specific objectives are to:
1.Understand how designers currently design products and what they need for developing environmentally friendly product design.
2.Develop a holistic framework for both generation and evaluation of environmentally friendly life cycle proposals.
3. Capture rationale as part of the design process.
4. Estimate uncertainty in the environmental impact assessment during design.
5. Evaluate product lifecycle proposals with multiple criteria under uncertainty.
6. Integrate design process with environmental impact assessment.
7. Apply environmental impact assessment through the design process.
From the descriptive studies we found that there is substantial difference in the environmental impact among products having the same functionality generated during the same design process. Analysis of industrial products available in the market show similar results. This means that design can substantially affect the impact created by a product. In our studies, designers did not consider environmental impact as a criterion in evaluation and we also identified the typical activities performed by designers during An Interactive Support for Developing Environmentally Friendly Product Lifecycles designing that must be allowed, supported or taken into account while developing a support for environmentally friendly product lifecycle design (EFPLD). The requirements of the designer for support are: tools should be proactive, easy to learn, understand and use, allow understanding of design rationale, act as a checklist, reduce total time, store knowledge and experience as know‐how backup, useful in all stages of design, not require too much extra effort for analysis, integrated to CAD, aid in trade off between choices, show uncertainty analysis, aid in analysis & improvement, and consider all lifecycle phases.
A holistic framework, ACLODS (is a acronym of the six dimensions) constituting the following six dimensions: a) Activities, b) Criteria, c) Lifecycle phases, d) Outcomes, e) Design stages, and f) Product Structure was proposed for development of environmentally friendly product lifecycle designs.
Through descriptive studies we found mainly 4 categories and associated sub categories of uncertainty in information with respect to LCA in design. The four categories are uncertainty in product structure, lifecycle phases, data quality, and methodological choices. The sub categories are assemblies, sub- assemblies, parts, relations, and features in product structure, material, production, distribution, usage, and after‐usage in lifecycle phases, temporal relevance, spatial relevance and sample size in data quality, and temporal relevance, spatial relevance, and comprehensiveness in methodological choices. At any point of time, uncertainty in information available is an accrual of the combination of the individual uncertainties.
A method called confidence weighted objectives method is developed to compare the whole lifecycle of product proposals using multiple evaluation criteria under various levels of uncertainty. It is compared with normal weighted objectives method and found to be better since it estimates the overall worth of proposal nd confidence on the estimate, enabling deferment of decision making when decisions cannot be made using current information available.
A new integrated platform IDEA‐SUSTAIN is developed in this thesis for supporting synthesis in product development on a commercial CAD workspace, while also aiding automated capture and storage of the rationale behind the decisions for retrieval whenever required during design. It is extended to support life cycle assessment of product proposals created by automatically extracting the information already stored while designing and ask for other information required to model the lifecycle without much extra effort from the designer. Then it uses the method for uncertainty reasoning developed also as a part of this research to estimate the level of confidence on the impact value owing to the incompleteness in knowledge available. The estimation is possible at part, assembly or product levels, for a single lifecycle phase or multiple phases.
Using in‐house design exercises and feedback questionnaire evaluation of support is done. The usage of Idea‐Sustain has been found to be the best for both generation and evaluation of product proposals. The two computer aided tools – software (LCA) and Idea-Sustain-are compared with each other for fulfilling the functional requirements by analysing the feedbacks given by the designers on these tools against these requirements. Idea‐Sustain fulfilled well most of the requirements while the software (LCA) fulfilled only some of the needs, that too less effectively.

An Extended Integrated Model Of DesigningRanjan, B S C 01 1900 (has links) (PDF)
Product success is a major goal of designing and design research. Designing involves developing systems. A system interacts with its environment to satisfy its requirements. Therefore, designing should involve developing the concept of both the system and its surrounding. Depending on how the concept of the system changes will impinge on the concept of the environment, and vice-versa; design must co-evolve the concepts of both the system and its environment to adapt them to each other.
A comprehensive review of literature on designing to explore the use of system-environment view in designing revealed that while the concept of systems is used by many design models, implicitly or explicitly, the concept of environment is rarely used as an evolvable construct in designing.
Activities, outcomes, requirement-solution and system-environment views play a significant role in product success. Thus, it is important to explicitly address these views in designing. Further, integration of these views is important for explaining various complex characteristics of designing such as requirement-solution co-evolution and system-environment co-evolution. Integration of views is important also for mapping the steps in design models using these views, so as to be able to characterize design models, or benchmark one design model against another.
Literature has been reviewed to identify the constructs in these views that are essential for representing the design process. Srinivasan and Chakrabarti [2010] had earlier developed a model of designing by integrating three of these views: activities, outcomes, and requirement-solution. However, this model did not incorporate the system-environment view. In this thesis, a system-environment view is developed, with both the system and environment as explicit and evolvable constructs in designing. The thesis then proposed an extended, integrated model of designing which combines the constructs of the identified views of activities, outcomes, requirement-solution and system-environment.
The proposed model is empirically validated using protocols from six design sessions; the sesessions had been undertaken well before the proposed model was developed.Validation involved checking whether or not instances of all the constructs in the model are naturally present in these design sessions, and whether or not every event in these design sessions could be described using the constructs of the proposed model.
Further, the explanatory power of the proposed model is illustrated by explaining how system-environment co-evolution and requirement-solution co-evolution occur during the design sessions captured in the protocols. Also, a standard prescriptive approach to designing –Pahl and Beitz approach – is used to demonstrate how a design model can be mapped using the constructs of the proposed model–the first step to characterizing or benchmarking design models.

Life Cycle Perspective in relation to ISO 14001 : 2015 and associated impacts of Design For Environment (DFE) and Sustainable developmentVattamparambil Nalan, Vishnu, Satheesan, Suraj January 2020 (has links)
ISO 14001:2015 is a certifiable environmental management standard applicable to any enterprise, large or small, in all fields of manufacturing or trades and services. It is the updated version of the previous ISO 14001:2004 standard. The updated standard contains a new High Level Framework which is expected to be used in the future by all ISO management system standards. ISO 14001:2015 sets out to implement methodologies such as the environmental management system and prescribes certification criteria including environmental policy and goals, important environmental issues, pollution reduction and continuous improvement of environmental efficiency. This report starts by looking into the documentation regarding life cycle perspective in the context of the ISO 14001:2015 standard. The revised model adopts a holistic approach across the value chain and encourages companies to accept a "life cycle perspective" with regard to the product and service design and development process. The methodology of life-cycle assessment (LCA) is also explored. The report goes on to examine another important aspect in environmental management which is the concept of Design For Environment (DFE). More specifically it is examined whether adhering to DFE principles can also help companies to adapt to the ISO 14001:2015 requirements. The concept of sustainable development in the context of ISO 14001 was given due precedence and it was found that ISO certified organizations will have an implicit awareness of sustainability because of the way ISO 14001 is structured. Corporate sustainability strategies were also discussed and this shed more light into how companies can
