Título del libro: Proceedings Of The Asme International Mechanical Engineering Congress And Exposition, 2014, Vol 11 Título del capítulo: Sustainability assessment of products: A comparative study of sustainability assessment tools
The number of existing tools, principles and approaches to assess
sustainability in products is growing to meet industry and society
needs. For those related to design and development in universities,
research institutes and companies it is a fundamental issue to recognize
features and details of the sustainability assessment tools in order to
select the one that best fits their particular needs. This paper
describes the outcomes of a product sustainability assessment carried
out at Universidad Nacional Autonoma de Mexico, UNAM. The approach
followed by the authors in this assessment was aimed at comparing the
results provided by a set of software tools and a previous
sustainability integrated-criteria tool developed by the research group.
The main contribution of this paper is the insight on the software tools
used and on the results of the assessment since the design point of
view. The results of the assessment included metrics such as: carbon
footprint, energy use, end of life potential, toxicity, eco-toxicity,
human toxicity, recyclability, and others. In the first part of the
paper, an introduction of the criteria and the software based tools for
sustainability assessment used by the authors is presented. Then a
justification of the tools used and an explanation on how the comparison
was achieved are given. The product used as a case study and the results
of its sustainability assessment are presented. The case study part is a
home appliance subsystem. In the end of the paper conclusions, insights
and further work are given.
