Research Presentation Day – Wednesday 21st January '04 Design for Sustainability (DfS) Mr Dare Awobiyi First Year (part-time) PhD Student Supervisor: Prof Neal Juster Dr Angela Stone Dr Alex Duffy
An Overview • Introduction • Definition of Design for Sustainability • Aims and objective • Concept of ‘Design for Sustainability’ • Discussion • Keywords • Design for Sustainability Issues • Literature survey findings on DfS • The gaps in current knowledge • Research questions arising from the gaps • Initial approach and methodology • Research next step • Conclusions • Any Questions?
Introduction • Definition of Design for Sustainability (DfS): Design for Sustainability can be defined as the process of designing goods and services that takes into account all dimensions of sustainable development, covering factors of environment, economic, social and the physical attributes required for the realisation of the products or services. • Aim and objective: The aim and objective of this research is to establish knowledge gaps in the DfS field and attempt at bridging some these gaps in order to advance knowledge of the subject. • Concept of ‘Design for Sustainability’ From the definition, it is evident that product design for sustainability is to be considered from total life cycle perspective, if all the sustainability circles are to be covered
Discussion • Keywords: Design, Sustainability, Design for Sustainability (DfS), DfS Metrics and Measurement, DfS Performance. • Design for Sustainability Issues • Environmental Impacts: • Pollution, Toxic substances, Waste management, Greenhouse gases. • Environmental Management System: ISO14000 series. • European Union Eco-Management and Audit Scheme (EMAS) • Waste Electrical and Electronic Equipment (WEEE) directive. • Unsustainable consumption of natural resources - (materials usage). • Energy Requirements to support the growing level of economic and social activities (world population growth). • Total life cycle approach for products development - cradle to grave. • DfS compliance: • new products • existing products
Discussion cont’d • Literature survey findings on DfS • DfS is a relatively new subject area. • No clear cut approach for determining DfS criteria from the perspective. of either a new or an existing product. • Designers lack the knowledge and design aids/tools to facilitate good decision making during design process execution. • A lot of the current knowledge and research works are centred on environmental issues. • The gaps in current knowledge • Lack of Concise Definition of DfS cycle. • Lack of sustainability criteria for product design and development. • Lack of DfS Performance framework by which different products can be measured and/or compared for sustainability criteria compliance
Discussion cont’d • Research questions arising from the gaps • What is DfS cycle for product realisation? • What are the design attributes that will fulfil sustainable development criteria? • What are the factors that define a new or an existing product under DfS framework? • How can DfS Efficiency (DfS) be measured and determined? • How can DfS Effectiveness (DfS) be determined and measured? • What measures a product’s DfS Performance?

Conclusions • Only the initial literature survey part of the research has been done • The gap in DfS knowledge established • The research questions aimed at developing the scope of work have been developed
