Understanding Consumer Behaviour to Reduce Environmental Impacts through Sustainable Product Design

The use phase of the lifecycle of electrical products has a significant environmental impact, mainly determined by the consumer’s behaviour. Many consumers do not make the link between their daily consumption behaviour in the household and environmental problems such as climate change. In the 21st century, the residential sector, together with transport and industry, is one of the largest man-made contributors in the UK to climate change. It is argued that technological innovations, current eco-efficient products and consumer education have been ineffective in creating the long term radical behavioural change needed to reduce the impact of product use. Products, as the interface between consumers and consumption activities, have the potential to influence the way in which consumption occurs. In the sustainable design field however, designer responsibility traditionally considers raw material selection and product disposal. There is limited work that addresses the environmental impacts relating directly to use behaviour of the product. This paper illustrates that user behaviour studies can be the preliminary step for designers to improve energy efficiency of products. A single product type, household cold appliance, was chosen as a case to explore the capacity of designer-conducted user study to identify unsustainable aspects of product use. Adopting a user-centred approach, two pilot studies were used to gain an insight into domestic fridge and freezer use in the UK. Qualitative ethnographical research methods were employed to investigate the daily practices and “real” needs of user as well as the connection between the knowledge, attitudes, intention and actual action. The design suggestions drawn from the user behaviour analysis provide examples of how energy impact level of the interaction with the product can be reduced through design.

Using a product's sustainability space as a design exploration tool

Sustainable design is often practiced and assessed through the consideration of three essential areas: economic sustainability, environmental sustainability, and social sustainability. For even the simplest of products, the complexities of these three areas and their tradeoffs cause decision-making transparency to be lost in most practical situations. The existing field of multiobjective optimization offers a natural framework to define and explore a given design space. In this paper, a method for defining a product’s sustainability space (defined by economic, environmental, and social sustainability objectives) is outlined and used to explore the tradeoffs within the space, thus offering both the design team and the decision makers a means of better understanding the sustainability tradeoffs. This paper concludes that sustainable product development can indeed benefit from tradeoff characterization using multiobjective optimization techniques – even when using only basic models of sustainability. Interestingly, the unique characteristics of the three essential sustainable development areas lead to an alternative view of some traditional multiobjective optimization concepts, such as weak-Pareto optimality. The sustainable redesign of a machine to drill boreholes for water wells is presented as a practical example for method demonstration and discussion

Exploring decision tradeoffs in sustainable design

Sustainable design involves three essential areas: economic sustainability, environmental sustainability, and social sustainability. For even the simplest of products, the complexities of these three areas and their tradeoffs cause decision-making transparency to be lost in most practical situations. The existing field of multiobjective optimization offers a natural framework to explore the tradeoffs in the sustainability space (defined by economic, environmental, and social sustainability issues), thus offering both the designer and the decision makers a means of understanding the sustainability tradeoffs. To facilitate this, a decision making approach that capitalizes on the principles and power of multiobjective optimization is presented. This paper concludes that sustainable development can indeed benefit from tradeoff characterization using multiobjecive optimization techniques – even when using only basic models of sustainability. Interestingly, the unique characteristics of the three essential sustainable development areas lead to an alternative view of some traditional multiobjective optimization concepts, such as weak Pareto optimality. The sustainable engineering design of a hypodermic needle is presented as a simple hypothetical example for method demonstration and discussion

Competence understanding and use in SMEs: a UK manufacturing perspective

The paper seeks to address the neglected area of competency research that is the understanding and application of core competency concepts within small and medium sized enterprises (SMEs). There is little doubt that SME manufacturing organisations can possess core competencies, however it appears from the literature that this issue has not yet been adequately addressed nor is there a clarification with regards to the nature of these competencies. This paper presents the results of an exploratory research study conducted with UK SMEs. The organisations involved were diverse and included a medical products manufacturer, automotive supplier, large metal fabrication and electromechanical capital equipment integrator. This research provides an insight into how competency concepts are perceived and understood amongst SME manufacturing firms and also whether these organisations use competence concepts. The research findings are important for both practitioners and academics, indicating an apparent lack of connectedness between research into competence and its ‘real world’ understanding and practical use within manufacturing SMEs

Happiness as a harmonising path for bringing higher education towards sustainability

This article was published in the journal, Environment, Development and Sustainability [© Springer Science+Business Media B.V.] The final publication is available at www.springerlink.com.This paper is a reflection of an innovative project that complements existing Higher Education for Sustainable Development (HESD) approaches within universities by providing an alternative path to embed sustainable lifestyles within the student population. It presents the SLEUTH project; an initiative born out of the need to reduce energy consumption of students at university but that, due to its systemic design, transforms and goes beyond purely energy reduction and brings Happiness as an approach to build sustainable lifestyles. This is the distinct feature of this initiative, proposing it as adding value to existing HESD approaches. The paper describes and discusses the collaborative building process, implementation and results in detail. The experiences gathered during the project are used and analysed through ‘participant observation’, ‘documents’, ‘questionnaires’, and ‘theme-ing coding’ techniques as a means to understand the richness and diversity of the data resulting from a combination of formal and informal learning settings. Through empirical evidence, this analysis presents ‘real life’ evidence to suggest, firstly the initiative’s design success, its impact on energy consumption and contribution to happiness and sustainable lifestyles. Secondly a successful example for the contribution to existing HESD frameworks that moves away from indoctrination and instead leans towards pro-activeness, self-organisation, and voluntary collective action
