What is

Existing Building Commissioning?

Existing Building Commissioning simply applies the commissioning process to buildings and systems that haven't been commissioned before. Unlike new construction commissioning, Existing Building Cx often includes an energy performance study, which produces a list of Energy Conservation Measures (ECM's) so owners can make no cost and/or cost-effective upgrades to their equipment/systems.

  • RetroCx is for an existing building that has never been commissioned.

  • Employs a total facility component and systems deficiency analysis to create a Commissioning Plan.

  • May or may not emphasize returning the facility to its original design intent.

What are the Objectives of the Process?

The following have been identified by owners as the primary objectives for existing building commissioning:

  • Bring equipment to its proper operational state

  • Reduce occupant complaints

  • Reduce O&M staff time spent on emergency calls

  • Reduce energy and demand costs

  • Improve system operation: beyond preventive maintenance

  • Improve building documentation

  • Improve indoor environmental quality (IEQ)

  • Increase equipment life

  • Increase asset value

  • Increase tenant satisfaction
