Session T3B Extended Abstract - Incorporating Sustainability in Engineering Design Courses Sandeep Dilwali Wentworth Institute of Technology, [email protected] Abstract - This paper discusses the topic of sustainability as relevant to engineering education. Factors which typically prevent incorporation of sustainability in engineering curricula are analyzed and possible solutions discussed. Examples of successful implementation of how sustainability and energy conservation was introduced in engineering design courses are presented. The focus of this paper is incorporation of sustainability and energy conservation in engineering curricula of sophomore and junior year students. Index Terms – Sustainability, engineering education, Sustainability education, engineering curriculum. INTRODUCTION Sustainability is gaining increasing importance and visibility, and is now more actionable than ideological. It has become a very popular term, even though there is some ambiguity about what all is considered to be included in this generic term. A product or process is considered sustainable if energy is conserved through economical means in a way in which human and social requirements are also met [1]. For this paper, Sustainability refers to activities that make use of the earth’s resources in a way which does not diminish their ability to support future generations. This includes consumption of energy in a manner that emphasizes renewable sources and makes efficient use of non-renewable sources. Sustainability is gaining significance and the importance of incorporating sustainability in all curricula cannot be underestimated. This paper will focus on incorporation of sustainability in engineering education, considering sustainability to be a part of a general education as a common thread across all engineering disciplines. It is to be borne in mind that no specific engineering program is being addressed, rather this paper is applicable to all engineering programs. CHALLENGES FOR INCORPORATION OF SUSTAINABILITY IN ENGINEERING EDUCATION Due to the relative novelty of sustainability, several challenges exist towards successful integration of sustainability education in engineering. Many studies have carried out to identify such barriers [2]-[5]. The following are the factors which present challenges to incorporation of sustainability in an engineering curriculum: Limitations of existing curriculum structure: The demands and desires on incorporation of newer and required concepts keep increasing in a typical 4 year curriculum for an engineering program. In an effort to maintain currency, and industry desirable skills, programs periodically revise their programs, generally adding content, and sometimes replacing content with outdated technologies. This leaves very little room to add courses in the area of sustainability, which may be considered as spanning several disciplines, and in a sense are very interdisciplinary in nature. Interpretation of sustainability: The interpretation of sustainability today is very diverse and not specific. It includes green engineering, renewable energy, and energy conservation. At times it seems too general, or vague to be included in any engineering curricula, and one of the barriers seems to be accepting sustainability as engineering [3]. Engineering Departments are Specialized: Most engineering departments consider themselves to be specialized in their discipline, and sustainability does not seem to be part of their department as it spans many aspects and disciplines including lighting, HVAC, insulation, water, sewage, pumps and motors, building construction, solar, wind etc. Inadequate importance : Sustainability continues to be a low priority as compared to other subjects to be incorporated in the engineering curriculum. It appears to be a less important aspect of engineering and so tends to get neglected or overlooked. Moreover, social and institutional aspects are given low priority [6]. The general acceptability of sustainability education decreases when it is viewed as a non-essential topic in engineering [5]. Lack of resources : Few faculty are trained in Sustainability. Since it is not in the comfort zone of many faculty, it seems questionable as to how to implement sustainability in the engineering curriculum, especially since sustainability seems to span several disciplines. STRATEGIES WHICH MAY FACILITATE INCORPORATION OF SUSTAINABILITY INTO ENGINEERING EDUCATION Conventional engineering designs strive to minimize cost and maximize performance. Green engineering often results in products that are neither the most cost-effective nor the longest lived, but engineers and consumers across the globe Mid Years Engineering Experience (MYEE) Conference T3B-1 March 22 – 24, 2015, College Station, TX Session T3B are realizing that sustainability is a critical feature. Engineering educators who would like to introduce principles of sustainable engineering to their students are confronted with the problem of adding more content to an already overstretched curriculum. Regular review of the engineering curriculum needs to be carried out and opportunities for incorporation of sustainability identified. Some of the strategies which may help incorporation of sustainability in engineering curricula are as follows: Sustainability in Engineering Design Courses. Engineering Design Courses, ideally in the sophomore and junior years, present an excellent opportunity to carry out energy conservation designs and projects. A great opportunity is to do such design projects is in collaboration with industry [7]. Interdisciplinary Department: Since Sustainability involves several disciplines including electrical, lighting, HVAC, water, insulation, energy conservation, business, steam, compressed air, and sewage, it seems overwhelming for one engineering department to address this in an engineering curriculum. If it were possible to have a department of Interdisciplinary Engineering or Sustainability, it may benefit all engineering programs [8]. Case Studies Approach: Case studies provides an excellent approach to incorporate sustainability in an engineering curriculum. There is an enormous amount of case studies freely available whereby organizations have reported upon their energy conservation projects, the approach they followed, and successes or failures they encountered. Students enjoy reading and analyzing these case studies, and are able to follow successful measures while carrying out energy conservation projects. Outcomes expected by ABET from any engineering program: Outcome c expected by ABET of any engineering program requires the student to have an ability to design a system, component, or process to meet desired needs within realistic constraints such as economic, environmental, social, political, ethical, health and safety, manufacturability, and sustainability. It is hoped that in the near future, all engineering programs will address the requirement of Sustainability. Simulation : Teaching simulation based energy conservation techniques to the undergraduate engineering students provides an opportunity to involve students with real-life engineering problems. [9]. Learning Communities : A Learning Community is a group of people who are interested in a common topic and engage in collaborative knowledge sharing as well as valued activities [10]. These members can help conduct projects in the form of Service Learning projects which provide an excellent education related to Sustainability part of Sophomore or Junior courses, or engineering design projects. IMPLEMENTATIONS OF ENERGY SAVINGS PROJECTS IN ENGINEERING DESIGN COURSES AT THE JUNIOR AND SOPHOMORE LEVEL As a method of incorporating sustainability in the Engineering Curriculum, few projects were tried out. These were as follows: Design of a nail salon : The City of Boston had issued revised guidelines for operation of nail salons in the city, with an aim of improving the indoor air quality. The students as part of the Engineering Junior Design carried out a detailed study of the requirements, and implemented a design which would meet all the requirements, while providing a very sustainable solution. They evaluated the energy savings and the payback period which would help the nail salon owners plan the retrofit of nail salon whereby they would conform the Regulations stipulated by the City. Energy Conservation Design – Lighting : Another Engineering Junior Design project focused on the lighting in an organization. The students inventoried all the existing lighting fixtures, found out the power consumed by each, and measured light output of each fixture. Then they reviewed the lighting requirements and the regulations, and suggested retrofits to lighting which would give the required light output while providing energy conservation. The payback period and savings due to reduced maintenance and standardization of inventory was also calculated. These two Engineering Junior Design projects, done by third year Engineering students, demonstrated the possibility of incorporation of sustainability in the engineering curriculum. It is interesting to note and that these students were from diverse engineering concentrations, and sustainability was a common thread in this interdisciplinary group of engineers. It is hoped that many engineering programs will try out similar engineering design projects at the sophomore and junior level as a way to incorporate sustainability in the engineering curricula. Similar projects were done Rowan University [11] whereby students learnt about engineering economics, HVAC, electricity, water, heat transfer, monitoring light, temperature, humidity and electrical power. CONCLUSION In a time of rapid transformation, as society seeks to build a more sustainable future, education plays a key role. It is important that we understand how to equip students with the capabilities to promote sustainability and how the higher education curriculum can be changed to facilitate the paradigm shift needed [12]-[15]. Training in sustainable practices is valuable for engineers because it brings these issues to the forefront of design plans and enables them to understand why some apparently more expensive options can also be the best options.
