The acronym CA stands for which term in commissioning contexts?

• A. Commissioning Authority
• B. Centralized Automation
• C. Chilled Air
• D. Control Assistance

Answer: (A)

CA stands for Commissioning Authority. The Commissioning Authority is the lead on the project for planning, managing, and executing the commissioning process to verify that building systems operate as the owner expects and as the design intends. This involves developing the commissioning plan, defining tests and acceptance criteria, coordinating pre-functional and functional performance tests, reviewing design and installation documents, and compiling the final commissioning report with a clear issues log. The CA acts as the owner’s advocate, coordinating between the design team, contractors, and building operations to ensure problems are resolved and documentation is complete so the building performs to the required goals before turnover. The other terms mentioned are not roles in the commissioning process: centralized automation refers to control system architecture, chilled air is a subject within HVAC, and control assistance is not a standard commissioning term.
