An essential goal of retro commissioning, re-commissioning, or on-going commissioning for a building’s energy using systems is to
A . reduce CFC-based refrigerants in HVAC&R base building systems
B . produce a master list of findings related to the commissioning process
C . execute an energy audit that meets requirements of ASHRAE Level 2
D . identify opportunities for cost-effective reduction in energy consumption

Answer: D

Explanation:

Retro-commissioning, re-commissioning, or on-going commissioning are quality assurance processes for existing buildings that aim to optimize performance and improve building operation. One of the essential goals of these processes is to identify opportunities for cost-effective reduction in energy consumption123. This involves verifying and documenting that the building and its systems and assemblies are operating efficiently and meet the current requirements of the building3.
