In this project a group of U of I Mechanical Science and Engineering (MechSE) senior design students will identify methods to reduce utility costs at the Siebel Center in conjunction with the Facilities and Services retro-commissioning team. The possible solutions investigated should include physical changes to the building and infrastructure, operational, and behavioral / cultural changes. Operational/behavioral/cultural barriers to implementation will be considered in formulating solutions. In addition, a preliminary design and lifecycle cost analysis of the potential solutions is to be conducted to determine which solutions are feasible. The student team will be able to provide additional analysis and design which will enhance the retrocommissioning team’s effectiveness and outline energy saving projects beyond the scope of the retro-commissioning team’s focus.
