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.
