Retro-commissioning Program Development
Retro-commissioning Program Development
E/S3 worked with University of Idaho Facilities Services Department staff to develop a retro-commissioning Program, with an approach specific to the University, that can be implemented internally as time and funding permits. This resulted in creation of a Retro-commissioning Program Manual by E/S3 for the University.
As part of this project, E/S3 performing retro-commissioning efforts on the complex systems in the Chemistry Building to refine the process, develop model strategies for building, HVAC equipment and control system types, and provide training for UI team members.
Major elements included a kickoff meeting to identify issues and opportunities for investigation, preparation for the on-site field investigation, executing the retro-commissioning plan and functional performance tests on building systems, performing minor repairs, trend data analysis, developing recommendations, preparing a retro-commissioning report and creating a Building Operator Manual.
Energy savings associated with several of the recommended improvements were estimated as part of the retro-commissioning process. Potential savings of $40,217 to $68,378 annually were identified, depending on how aggressively the measures for the main air handling units are implemented, representing a 17% to 29% reduction in overall energy costs.
