The course content provided a basic overview of the various stages involved in the Commissioning process of Existing buildings.

Good basic overview of the commissioning process that lays out the steps well. The review of the process on the San Diego Convention Center is informative. It's always nice to see case studies of processes in action.

The content is accurate but brief, it could use more examples. It would be nice to have a second part in intermediate level, so more topics about commissioning in new and existing buildings can be explained.

Thank you for your comment. We did produce an intermediate level presentation as well. "Existing Building Commissioning Process: Implementing RetroCommissioning on your project" - GBCI: 0920001136. The intermediate level presentation includes some real world examples of RCx and some case study information. We also go deeper into the RetroCx process. I hope you find it helpful.

The Content is relevant to the learning objectives but is very short and very theoretical, instead , it could have been much more rich with real examples from commissioning projects. Some videos from real commissioning projects could be shown in the course.
