- W2319128647 abstract "Today’s engineering problems require complex solutions from multiple disciplines. Hence, engineering classes should teach students to learn about how to solve multidisciplinary problems. This paper describes a project-based course that allows a group of students to learn and utilize knowledge and approaches from multiple disciplines, gain systems engineering perspective to solve a real-world problem. The objective of the project is to develop a system that can facilitate the monitoring and analysis of the performance of HVAC systems, which account for about 40% of total energy consumption in buildings. Students with various backgrounds worked together to develop a prototype system that automatically collects dynamic data from HVAC systems, and visualizes the real-time and historical data with floor plans using a web-browser-based interface. This prototype system also embeds fault detection and diagnosis (FDD) algorithms that frequently analyze the performance of HVAC systems. In developing such a system, the students had to learn and utilize knowledge in the domain of civil, mechanical, electrical engineering, computer science, and project management, approach the problem from a systems engineering perspective. This paper discusses the processes that the students went through to learn, implement and test the system in a real-world testbed. INTRODUCTION AND BACKGROUND According to the data from the U.S. Energy Information Administration (EIA), buildings use more than 42% of the total energy and are the largest energy consumer in the U.S. (EIA, 2008). Previous studies found that about 20-40 % of the energy used by the HVAC systems is wasted due to undetected faults, such as biased sensors, stuck dampers, and unstable controllers (Roth, 2005). The comfort and productivity of occupants are also impacted by the faults, if the indoor air quality, specifically temperature and concentration of CO2 particles, is affected (Widodo, 2007). Hence, increasing energy efficiency of HVAC systems is essential to improvement of the overall energy performance of buildings. Designing and operating HVAC systems involve engineers from a variety of disciplines, such as architecture, mechanical engineering and electrical engineering. Hence, efficiently operating the HVAC systems requires a multi-disciplinary approach, which is not commonplace in a classroom setting. There are various ways" @default.
