Engineering Education, 2017 Modeling the Effect of Renewable Energy and Smart Appliances in Energy Reduction of Residential 1 Homes Using GridLab-DI. INTRODUCTION AND BACKGROUND When used in concert, microgrid and smart grid technologies have the ability totransform the way power is delivered. A microgrid is a localized energy grid with a colocated setof power generation sources and loads, with autonomous control, which can operateindependently of the traditional power grid [1]. As a result of this ability for autonomous control,it is possible for microgrids to connect to the main power grid or act in an “islanded” mode.Microgrids can be more efficient than traditional grids due to the

The University ofDayton Industrial Assessment Center is one of twenty-six Department of Energy funded Centers.It has been in operation since the early 1980’s and has completed over 950 industrial assessments.In the years of operation, the Center has developed many spreadsheets, software programs, andreport formats which it made available to the Ohio Lean Building Project (OLBP). Colleges anduniversities wishing to replicate such a program would also have access to the “Energy EfficiencyGuidebook.”Formal Program GoalsThe program’s goals: 1. Train the next generation of energy engineers and technicians in building energy efficiency. 2. Make Ohio’s buildings more energy efficient by

IntroductionAs human population, new technologies, and infrastructures continue to grow, there isa proportional increase in the demand for energy need. Currently, most energy in theUnited States is produced by fossil fuels. For the last century, petroleum, natural gas,and coal had accounted for at least 80% of the total U.S. energy consumption.[1]However, burning fossil fuels produces pollutants and heat-trapping gases
the compressor is to increase the absolute pressure and thus increase the density, whichdecreases power requirements.Thus, there is a motivation to design gas pipelines for the highest pressure that thetechnology allows, whereas there is no incentive for high pressure in an oil pipelines. Themaximum pressure in the oil pipeline only has to be as high as the frictional pressure dropbetween pumping stations. An infinite number of pumping stations, which means no distancebetween pumping stations, would result in the need for no additional pressure aboveatmospheric in the pipes. II. Projects and OrganizationThe five projects were 1) the design of a long crude oil pipe line with multiple pumpingstations, 2) re-designing this pipeline to
middle of the process for certifying a second LEED Lab building oncampus, and here are the main lessons they have learned from the first LEED Lab building: 1. Make sure the prerequisites can be met. For example, the LEED for Existing Buildings requirement stipulate a 20% reduction in energy consumption as a prerequisite. If the building under consideration is already energy-efficient, this may present a challenge. However, USGBC has a “Energy Jumpstart” Pilot credit in case the building is having a problem with meeting this prerequisite. USGBC does not want to penalize buildings that have continued to perform efficiently, so this is valuable. 2. Keep in constant contact with the university’s Facilities Planning and
Basic Chemistry & BiologyThe basic concept of a bacterial fuel cell is illustrated in Fig. 1, from Ref. 1. The overall processis summarized as follows: 1. Bacteria on the anode decompose organic matter and free H+ ions and electrons. 2. Electrons flow from the bacteria to the anode, sometimes assisted by a mediator molecule. 3. Electrons flow up from the anode through a wire to the cathode generating electrical current. 4. The H+ ions flow through a semi-permeable membrane to the cathode. This process is driven by the electro-chemical gradient resulting from a high concentration of H+ ions near the anode. 5. Electrons from the cathode combine with dissolved oxygen and the H+ ions to form pure

Traditional courses, such Thermodynamics or Heat Transfer weregiven a focus on renewable energy conversion systems on learning modules enhanced byexperimental activities, while new courses geared towards energy management or renewableenergy were developed. Students ’assessments and feedback clearly showed that this change wasa success, ranking these courses consistently above 3.8 out of 5 on a Likert scale [1]. Studentschose capstone projects ‘topics preponderantly from the same industrial areas, clearly showingthe interest in green

Introduction, Project Goals, Aims and ObjectivesMajor challenges facing our society, such as energy, water, environment or health have neverbeen more prominent than they are today1-3. Engineers and educators, as problem solvers need toaddress these challenges in sustainable ways.

Our open-ended discussion timewas guided by the following questions: 1. What was your ‘employment objective’ for your first job in the energy field? 2. What skills/abilities were most important to you in your first job in the energy field? 3. What do you look for when hiring for entry-level jobs in the energy field? 4. What characteristics are evaluated in performance reviews for entry-level engineers in the energy field? 5. What range of advanced education and training opportunities are important for graduates of an energy engineering undergraduate program? 6. What
fuels has been theprincipal driver for much of today’s energy research. While the price of oil has been at historicallylow levels over the last two years (2014-2016), predictions of production limits by TheOrganization of Petroleum Exporting Countries (OPEC) have contributed to the most recent boutof price instability [1]. In addition to economic concerns, the environmental impacts of traditionalfossil fuels (FF) cannot be ignored. Significant changes to global ecosystems through both theacquisition and use of FF have been witnessed within the last seven years [2-3]. The catastrophicexplosion of the Deep Water Horizon oil rig in 2010 has left an indelible mark on sensitive coastalecosystems along the US Gulf Coast, with impacts likely to be

This expectation highlights the need for expanding the learning environment ofSTEM students by providing them with additional active learning and research opportunities as ithas been shown that active learning opportunities increase their chances for obtaining a degreewithin their field of study while also helping them turn what has been learned into actual skills[1].The truth is that learning should be fun and exciting. As educators it is our responsibility to keepstudents engaged and provide them with a learning experience that is both meaningful andexciting. Historically, however, the classroom has primarily been a passive learningenvironment where knowledge is taught by experts with occasional

Many of these outcomes contributetowards ABET learning outcomes.IntroductionWhatever type of refrigerating system is being used, it is fundamental to minimize the requiredheat extraction and to keep the difference between “Tc” (condenser unit temperature) and “Te”(evaporator unit temperature) as small as possible [1].Residential and commercial buildings compose 40% of the US primary energy of which 75% iselectrical.

Thankfully, engineering education has been expanding its boundariesrapidly to encompass the emerging disciplines that are the foundational elements of thisimportant focus area [1] Frequently, the focus is on new construction, but much of the bestenergy savings can be found in renovation of older structures, and, typically, the more complexthe systems in those older buildings, the bigger the potential savings as those structures arebrought up to modern standards. This means that graduates of modern engineering designprograms need to have a solid knowledge base from which to draw, including being capable

Thisproject and similarly embedded projects in courses are thought to increase students' knowledgeby involving them in an active learning environment while solving or analyzing real worldproblems and challenges.Introduction Heating, ventilation and air-conditioning (HVAC) systems are the largest electricity-consuming sector in residential buildings in the U.S. [1]. According to [2], the U.S. EnergyInformation Administration indicated that more than 40% of the total energy consumption in theU.S. is in residential buildings. This figure is slightly less in Canada with 30
of the engineering curriculum. Engineering learningmethods and technology are constantly evolving [1] but the industry is still using traditionalmethods such as MS Office due to its widespread use, easiness, and low cost [2], [3], [4].Therefore, in energy-related courses, an educational tool based on applications such as MS Excelis useful in the transitional period between pen and paper and more advanced and costly softwareapplications. Moreover, accessible applications can be used to enhance educational goals like theassessment of the energy consumption of these energy-efficient technologies.To address the use of accessible applications in the learning of energy-efficient technologies, thispaper describes a Combined Heat and Power (CHP

engineeringdisciplines. Solar and wind in particular are fields of high interest. In response to this demand,the mechanical engineering department at Cal Poly has created an Energy Concentration to allowstudents to focus on energy production, transformation and transport [1]. The concentrationincludes a wide variety of courses related to the energy field so students can acquire a broadexpertise. In evaluating our courses, along with courses offered by other departments, werealized that they tend to focus on the discipline related to the department providing the courseand that the multidisciplinary aspect of the energy industry is often lost. These courses, beingfocused on one discipline, also tend to limit the possibilities for exploring open ended questions.In
students’ academic careers.IntroductionThere are several studies which detail the benefit of student collaboration and networking [1],[2]. However, there are not always adequate opportunities for students to network andcollaborate with other students and faculty outside of their home institution. Therefore a summerprogram was developed by the FEEDER (Foundations in Engineering Education for DistributedEnergy Resources) Consortium, in hopes to not only increase the ability for students to networkand collaborate, but to expose the students to a wide variety of technologies that they could notsee otherwise. This strengthens several of the soft skills that are very important in thedevelopment of a young engineer’s career, but are often times
