Existing building commissioning

摘要

Retro-commissioning, or existing building commissioning is, simply put, commissioning of building systems that have not been previously commissioned. While the industry refers to this as retro-commissioning or RCx, the AABC Commissioning Group (ACG) prefers the term "existing building commissioning," because RCx implies returning the systems to an earlier state of functionality. But what if the earlier state of functionality was awful? The focus should be on setting up the systems to a fully functional, reliable, maintainable state of condition that meets the hospital's current needs.
