Dr. Ahmed Cherif Megri, Associate Professor of Architectural Engineering (AE). He teaches capstone, lighting, electrical, HVAC and energy design courses. He is the ABET Coordinator for the AE Program. His research areas include airflow modeling, zonal modeling, energy modeling, and artificial intelligence modeling using the support vector machine learning approach. Dr. Megri holds a PhD degree from INSA at Lyon (France) in the area of Thermal Engineering and a ”Habilitation” (HDR) degree from Pierre and Marie Curie University - Paris VI, Sorbonne Universities (2011) in the area of Engineering Sciences. Prior to his actual position, he was an Associate Professor at University of Wyoming (UW) and prior to that he was an Assistant Professor and the Director of the AE Program at Illinois Institute of Technology (IIT). He participated significantly to the development of the current architectural engineering undergraduate and master’s programs at IIT. During his stay at IIT, he taught thermal and fluids engineering (thermodynamics, heat transfer, and fluid mechanics), building sciences, physical performance of buildings, building enclosure, as well as design courses, such as HVAC, energy, plumbing, fire protection and lighting. Also, he supervises many courses in the frame of interprofessional projects (IPRO) program. Dr. Megri wrote over 100 journal and conference papers. Overall, Dr. Megri taught more than 30 different courses at University level in the AE area.

Areas of Interests:
- Zonal modeling approach,
- Integration zonal models/building energy simulation models,
- Zero Net Energy (ZNE) building,
- Airflow in Multizone Buildings & Smoke Control,
- Thermal Comfort & Indoor Air Quality,
- Predictive modeling and forecasting: Support Vector Machine (SVM) tools,
- Energy, HVAC, Plumbing & Fire Protection Systems Design,
- Computational Fluid Dynamic (CFD) Application in Building,

Introduction of Diagnostic Problem-Solving Approach within UndergraduateDesign Courses – Application to Building IlluminationAbstract:The engineers are usually confronted to two types of problems: design or investigative problems.The new design problem concerns the creation of a new product (in our case the product is abuilding, building component, mechanical or electrical system) and the investigative consists offixing an existing product using a sequential diagnostic.It is a logical, systematic search for the source of a problem so that it can be solved, and so theproduct or process can be made operational again. Investigation is needed to develop andmaintain complex systems where the symptoms of a problem can have many possible causes.In this paper, we introduce how these two notions have been introduced to undergraduatestudents through basic design courses. A case study from building engineering is presented:building illumination investigation in elementary schools will be presented and discussed.We discuss the design work from students’ point of view, and the experience earned in design,experimentation, and also in written and oral communication skills. Future plans to evaluate theeffectiveness of the case studies in terms of learning outcomes, as well as plans to evaluate it inundergraduate architectural engineering training are also presented.
