Eco Global Evaluation: Cross Benefits of Economic and Ecological Evaluation

This paper highlights the complementarities of cost and environmental evaluation in a sustainable approach. Starting with the needs and limits for whole product lifecycle evaluation, this paper begins with the modeling, data capture and performance indicator aspects. In a second step, the information issue, regarding the whole lifecycle of the product is addressed. In order to go further than the economical evaluations/assessment, the value concept (for a product or a service) is discussed. Value could combine functional requirements, cost objectives and environmental impact. Finally, knowledge issues which address the complexity of integrating multi-disciplinary expertise to the whole lifecycle of a product are discussing.EcoSD NetworkEcoSD networ

Greening information management: final report

As the recent JISC report on ‘the ‘greening’ of ICT in education [1] highlights, the increasing reliance on ICT to underpin the business functions of higher education institutions has a heavy environmental impact, due mainly to the consumption of electricity to run computers and to cool data centres. While work is already under way to investigate how more energy efficient ICT can be introduced, to date there has been much less focus on the potential environmental benefits to be accrued from reducing the demand ‘at source’ through better data and information management. JISC thus commissioned the University of Strathclyde to undertake a study to gather evidence that establishes the efficacy of using information management options as components of Green ICT strategies within UK Higher Education environments, and to highlight existing practices which have the potential for wider replication

Eco-innovative Method to Improve the Distribution Phase of Product

The integration of the environmental dimension is crucial in industrial activity. Designers should integrate the new environmental constraints to adapt their approaches and methodologies in the framework of eco-innovation of industrial products and consumer goods. This paper proposes a new method integrating ecological aspects into the innovation process composed of three main stages: an analysis and structuring of the product, the formalization of the problem and the resolution phase. According to the structuring and the design objectives, actions can be selected and allow to guide the design to the most relevant modification to perform on the product. An illustration of the approach is applied on the optimization of the environmental impacts related to the logistical aspects

Sustainability in Software Engineering

The intersection between software engineering re- search and the problems related to sustainability and green IT has been the subject of increasing attention. In spite of that, we observe that sustainability is still not clearly defined, or understood, in the field of software engineering. This lack of clarity leads to confusion about e.g. what is relevant to measure or the research implications over time or space. This paper provides an overview of how the research so far has defined sustainability, and how this definition has been used to guide which research areas. To this end, we carried out a systematic mapping study for selecting, classifying and analyzing relevant publications. In this study, we investigate which knowledge areas and which time scope of sustainability effects are mostly targeted in scientific research. Our analysis shows research trends and discusses gaps to be filled

Practical limitations in Embodied Energy and Carbon measurements, and how to address them: a UK case study

The built environment is blamed for producing the majority of carbon emissions. While policy remains focused on emissions during the operational phase, research demonstrates that embodied impacts are a significant proportion of whole life ones. This paper presents a case study of a building that integrates low-energy design features. The study was carried out during the construction phase enabling superior quality of data to be collected. The cradle-to-grave embodied impacts were modelled to the TC350 Standards using an innovative tool, and the operational impacts through simulation, incorporating future climate predictions. In spite of the data quality, the study demonstrates a high level of uncertainty due to a number of industry-wide issues. This paper identifies these issues and concludes that considerable barriers to measuring embodied impacts remain. Key recommendations are made for industry and policy, in order to gear up the measurement and reduction of embodied impacts of buildings

Integration of end-of-life options as a design criterion in methods and tools for ecodesign

Ecodesigning a product consists (amongst other things) in assessing what its environmental impacts will be throughout its life (that is to say from its design phase to its end of life), in order to limit them. Some tools and methods exist to (eco)design a product, just like methods that assess its environmental impacts (more often, a posteriori). But it is now well accepted that these are the early design decisions that will initiate the greatest consequences on the product’s end-of-life options and their impacts. Thus, the present work aims at analysing traditional design tools, so as to integrate end-of-life possibilities in the form of recommendations for the design step. This proposal will be illustrated by means of a wind turbine design.EcoSD networ
