In a large industrial or commercial building, which energy end uses are classified as systems composed of discrete pieces of equipment that can be metered together for the purposes of Energy and Atmosphere Credit, Advanced Energy Metering?
A . HVAC air system for air conditioning
B . Electrical lighting system during peak use hours
C . Water flow system used for public faucets and toilets
D . Condenser water system with a cooling tower and condenser water pumps

Answer: D

Explanation:

A condenser water system with a cooling tower and condenser water pumps is classified as a system composed of discrete pieces of equipment that can be metered together for the purposes of Energy and Atmosphere Credit, Advanced Energy Metering. This is because the condenser water system is a single energy end use that serves a specific function and can be isolated from other systems1. HVAC air system, electrical lighting system, and water flow system are not considered as single energy end uses, but rather as multiple energy end uses that serve different functions and cannot be easily isolated2.
