Integrating Eco-Design in Manufacturing Materials and Processes Related Courses - Material Selection for Sustainable Design using CES PackageResponsible design aims to provide safe, affordable services while minimizing the drain onresources and the release of unwanted emissions. This can be accomplished by performing anongoing eco-audit of the design (or redesign) as it progresses. As we teach engineering materialsand manufacturing process courses prior to capstone senior design projects, it is imperative tointroduce Engineering Technology (ET) students with advanced tools to impart skills that willguide design decisions that minimize or eliminate adverse eco-impact. Embodied energy andcarbon footprint, recycle fraction and toxicity have obvious eco- connections that require carefulconsiderations for Product Lifecycle Assessment (PLA) combined with mechanical, thermal, andelectrical properties that have the greatest role in design to minimize eco-impact. Several coursesin ET curriculum have been used during the past AY to infuse sustainability, eco design andgreen energy production teaching materials and projects into Mechanical EngineeringTechnology courses such as Materials, Mechanical Design, Manufacturing Processes and SeniorDesign Capstone course sequence.This investigation aims to evaluate from student learning perspective the benefits ofincorporating software based eco-design team projects into main required courses in ourEngineering Technology curricula. The benefits are assessed based on several tools rangingfrom questionnaires administered to students to assessment of students’ knowledge and expertisedemonstrated in the student-led projects. Questionnaires are also based on evaluating the level ofpractical knowledge gained by the students during the development of such projects on one handand on whether the project has a multidisciplinary character and to what extent. Another aspectincluded in this research is the students’ involvement in evaluating the outcomes of fellowstudents’ projects.During the past AY authors used two software packages: Cambridge Engineering Selector (CES-Edupack 2013) and our existing SolidWorks2013 package with Sustainability “addin” functioninvoked to provide tools to meet complex product and process design requirements, helpingstudents to explore and learn the underlying science of eco-design in a sustainable environment.While CES EduPack Sustainability database package provides a computer-based resource forassessing articulations of sustainable technology and the place of materials in them, SolidWorkssustainability evaluates the environmental impact of a design throughout the life cycle of aproduct. Students are required to compare results from different designs to ensure a sustainablesolution for the product and the environment.These approaches have been studied by the authors since AY 2012-2013 and have beensuccessfully implemented in most of the courses taught by them. As a general outcome, studentsbecame more involved during class time and also they shown interest in sustainable eco-designareas, being involved in more advanced course research activities. Several students also electedto develop their own ideas during team projects and undertook projects of a wider PLA scope.
