learning.Lastly, discussions between Kerestes and Dolloff have led to the feeling that it is difficult todeliver and assess assignments based on smart grid technology. Many of the technologies arenot yet commercialized nor have even been realized. Therefore, a good component to add tothe course would be in-class discussions based on new and emerging smart grid technologies.Kerestes would assign either readings or videos on new distribution-level smart gridtechnologies and have a discussion on them in class. Based on this discussion, students wouldbe assigned to write reflective papers for assessment. In these reflections, student would haveto consider ethics, sustainability, economics and global impact. This would drive continuousimprovement of the

and air-conditioning systemsof the building [2]. The world equipment demand for heating, ventilation and air-conditioning(HVAC) has increased from 50 billion US dollars in 2004 to more than 90 billion US dollars in2014 and for the US from almost 11 billion to 19 billion US dollars over the same period [3]. Areduction in the HVAC energy consumption load would reflect a significant reduction in the totalenergy consumed.In this paper, the improvement in refrigeration efficiency and COP were analytically investigatedby looking into a shaded condenser as compared to unshaded units. Thermodynamic equilibriumand energy conservation equations were used to estimate changes in the condenser temperatures.MethodologyThe study assumed that the difference

low-tech, low-cost, and safe for students to construct with minimal experience. This paper details the development ofthe “Appalachian Street Lamp,” an off-grid renewable electricity kit, provides an evaluation of studentlearning outcomes, and a summary of survey responses. Our objective is to reflect on the value ofincorporating hands-on learning during a study abroad program.Global CompetencyGlobal competency is of increasing importance in our complex and interconnected world. It inspiresstudents to appreciate cultural value differences, learn new language, and better understand a globaleconomic and cultural marketplace. It also fosters working effectively in diverse and multi-culturalenvironments while developing attitudes that cultivate

theproject was used, but the 8 outcomes below reflect accurately the consistent goals of the courseand form a basis for what features needed to be included in a project. 1. Students will develop problem statements and design criteria/requirements by evaluating a project scenario using design techniques (such as mind mapping or functional decomposition). 2. As a part of a design team, students will use the engineering design process to design, create, and evaluate a prototype that addresses realistic design constraints and requirements. 3. Students will self-assess, select, pursue, and demonstrate competency with a variety of tools, methods, and software as determined by their program. 4. Students will analyze

their efforts, which can be difficult both for tenure-track faculty who are evaluated based onresearch publications as well as non-tenure-track faculty with high teaching loads.In reflection of these lessons learned, we plan to continue to implement these projects in classeswherever relevant, including both design- and energy-focused courses, in addition toindependent study and research projects. Continuous project refinement is needed to ensure thatprojects are well-defined and tractable for students. All projects will require regular feedback andinteraction with facilities staff to ensure both project relevance and implementation of projectresults. Finally, the continued pursuit of institutional-level resources will be needed to providethe

As a whole, student performance onthe group project exceeded performance on exams. As this was a newly developed courseoffered for the first time, student performance proved a positive reflection on the coursedevelopment.

severaldays, the power generation curve from the solar panels under smoggy conditions remained“smooth”.Table 7 lists the peak and average power output for each converter type, as well as the total dailyenergy generated under smoggy conditions. From the data, it is evident that the smog diddecrease the power generated from the solar panels but not to the same extent as that of shadingthe panels. This is because even with the smog, diffuse and reflected irradiance were able toreach the solar panels.

students toencounter the core concepts and principles, while managing a specific project, thereby enablingthe acquired knowledge application. PBL goes beyond the relationships between knowledge andthinking, helping students to both know and do. In fact, it is focuses on doing something andlearning on the way [8, 12-27]. PBL main features from the student learning point of view are:1. In PBL, a student-centered approach, the focus is on the student competencies to design and toreach the solution, around their concerns and skills, the end product being a reflection of them.  2. In PBL the students solve problems, through self-management, project management, andcritical knowledge are enhanced, as they manage the work, offering frequent feedback, self
