Dr. Shehadi is an Assistant Professor of Mechanical Engineering Technology (MET) at Purdue University. His academic experiences have focused on learning and discovery in areas related to HVAC, indoor air quality, human thermal comfort, and energy conservation. While working with industry, he oversaw maintenance and management programs for various facilities including industrial plants, high rise residential and commercial buildings, energy audits and condition surveys for various mechanical and electrical and systems. He has conducted several projects to reduce carbon dioxide and other building emission impacts by evaluating and improving the energy practices through the integration of sustainable systems with existing systems. His current research focuses on engaging and educating students in sustainable and green buildings' design and energy conservation. He is currently investigating various ways to reduce energy consumption in office buildings.

Abstract

Part of Purdue University MET (Mechanical Engineering Technology) program is to educate its students on energy conservation in general and for buildings in specific. In this study, which was part of a project in HVAC & Refrigeration class (MET 42100), the team decided to investigate energy consumption trends for a typical house/apartment under actual outdoor conditions and following different indoor temperature schedules and scenarios. The indoor base temperature was set to 72° F. Different schedules were created sometimes increasing the temperature during day or night time, shutting off the system when the outdoor temperature was cool and adequate, opening balcony doors or windows while keeping the system on, etc. Daily energy consumed for each case was collected using the electrical company’s database who collects and stores all data using smart meters for the investigated apartment. It was seen that increasing the indoor set temperature by 1-5° F for couple hours in the afternoon or at night can save up to $80 per month or even more if combined cases were adopted. The results presented in this study depend on the circumstances of the house where the data was collected and it may not replicate the same/exact results if applied to other apartments/houses. The project helps the students meet the course learning outcomes in addition to ABET learning outcomes for MET programs. Students gained analytical and experimental skills, applied science and technology to engineering theories and applications, worked in a team, and developed their communication skills such as oral and written skills.
