Which two phases are identified for the Retro/Re-Commissioning process?

• A. Planning and Implementation
• B. Planning and Execution
• C. Design and Construction
• D. Evaluation and Commissioning

Answer: (A)

Retro/Re-Commissioning is treated as a two-phase effort focused on existing buildings: planning and implementation. In the planning phase, you scope the RCx project, gather and analyze energy data, establish a baseline, identify and prioritize potential retrofits, and set objectives, metrics, and a plan for measuring success. The implementation phase then covers selecting and installing the recommended measures, adjusting controls, training operators, and verifying that the expected energy savings and improved performance are realized. This structure keeps the work organized: first decide what to change and how you’ll measure it, then carry out the changes and confirm the results. Other pairings shift focus toward new construction design/construction or post-occupancy verification in contexts that aren’t the standard RCx two-phase approach.
