In this paper, we analyse two approaches that attempt to address how a human factors and ergonomics (HFE) perspective can contribute to the sustainability of the human race. We outline the principles, purposes and fields of application of ergoecology and green ergonomics, and thereafter deal with their context of emergence, and the overlaps in purpose, and principles. Shared values are deduced and related to socio-technical principles for systems' design. Social responsibility and environmental/ecospheric responsibility are the leading threads of ergoecology and green ergonomics, giving rise to the values of: respect for human rights, respect for the Earth, respect for ethical decision-making, appreciation of complexity, respect for transparency and openness, and respect for diversity. We discuss the consequences of considering these values in HFE theory and practice.

The current paper deals with the definition of sizes for the design of school furniture for schools in Bogotá, Colombia, based on an analysis of available anthropometric data on Latin American children. State-of-the-art anthropometric, national and international standards were considered, in order to define the anthropometric variables that were to be used for defining the furniture. Matrices relating age and specific anthropometric dimensions were constructed, as a visualization method for establishing the dimensional differences between children of the same age and the ranges that should be covered by the items of furniture. Dimensional data were grouped by establishing the minimum sizes and general dimensions of furniture needed to cover the 5-95th percentile of school children between the ages of 5 and 18 years. The distribution of the furniture in the different school grades was also indicated. Apart from the need for an adequate match between child anthropometry and school furniture dimensions, this study shows the importance of a proper distribution of furniture sizes in the different school grades, as a complementary and decisive aspect to be considered in order to meet the heterogenic, anthropometrical requirements of children of the same age and school grade.

This article conceptualises a new multidisciplinary field by establishing the elements of an 'ergonomic system' (human beings, physical space and object/ machine) and defining the term 'surroundings' (PESTE factors) while emphasising the ecological aspects of human activities. The definition of ergoecology is explained by an etymological analysis of the names of the contributing disciplines (ergonomics and ecology). The new multidiscipline combines and extends the scope of the two foundational disciplines using new principles, notions and concepts, such as 'built environment', 'surroundings', 'ergoecology', 'ecoefficiency' and 'ecoproductivity'. The aim of ergoecology is to provide tools for confronting twenty-first century challenges. In line with the sustainability movement, we believe in the importance of using ecologic and ergonomic perspectives (in their broadest sense) to develop action aimed towards environmental preservation and the development of sustainable products, processes and service designs.
