How we measure 'reads'
A 'read' is counted each time someone views a publication summary (such as the title, abstract, and list of authors), clicks on a figure, or views or downloads the full-text. Learn more

Introduction
I have been studying Sustainability Engineering since 1996. While traditional engineering seeks to maximize utility while minimizing cost to the client, Sustainability Engineering must vastly expand the concepts of 'utility', 'cost' and 'client' to become something closer to 'maximizing social benefit while minimizing negative ecological impact'. . www.sustainabilityengineering.net

There is a truism in Engineering that requires that a problem cannot be solved until it has been adequately defined. Sustainability can be perceived as a Wicked Problem, which suggests that it has not been adequately defined. Perhaps Sustainability resists definition, but a more optimistic approach would be to try a different way to define it. In t...

Traditional engineering is a process of maximizing utility while minimizing cost to the client. Engineering for sustainability must vastly expand these concepts to become a process of "maximizing social benefit while minimizing negative ecological impact." This paper explores the descriptions surrounding sustainable development, and completes them...
Conference Paper
Full-text available
Goal models have established themselves as a means to capture often conflicting needs of stakeholders and reason about how alternative solutions may impact those needs, allowing for trade-off assessments at the early stages of development. More recently, goal models have been extended with the notion of indicators that allow quantitative, real-life...

Sustainability Engineering seeks to maximize quality of life within a community while minimizing negative ecological impacts. People use their time to meet their wants and needs, or they use their time to convert resources into the means to meet their wants and needs. By focussing on the second part of that statement, and concentrating on resources that are available to the community in perpetuity, and on the needs of the community, Sustainability Engineering can produce a maximum of time for activities other than those required to meet needs - the Potential Quality of Life. The math that is used measures the time spent at activities that meet needs (Meeting Needs prevents the degradation of the self, family, or community), but does not measure if all of the needs in the community are met. It would be expected that a significant portion of the population would not have all it's needs met, despite the presence of a significant amount of time that is spent on 'wants'. That suggests there are obstructions within a community that prevent people from being able to meet their needs, regardless of the time they spend. I would like to identify and quantify the obstructions within a community that prevent people from being able to meet their needs, so that I can predict the improvement in the Actualized Quality of Life for each alternative design, rather than only the Potential Quality of Life. I wonder if the presence of unmet needs within a community can be identified by using Chronic Stress as an indicator. I wonder if the recipe for Chronic Stress is simple enough that the cause(s) of the stress can be determined. I wonder if the causes can be assembled across the community to identify the actual obstruction. Further to that, can we measure effectiveness of each activity to meet needs by comparing how much time people within the community spend at any particular activity, and how much time people who have the associated need met spend at that activity? Right now, I'm collecting data to test these questions.
