According to the LEED V5 : Building Design + Construction Guide, the Water Efficiency Prerequisite, Indoor Water Use Reduction requires the project to reduce the aggregate water consumption from plumbing fixtures and fittings by at least 20% from the baseline. The baseline water consumption is determined by the Energy Policy Act of 1992 and subsequent rulings by the Department of Energy, or a local equivalent for projects outside the U.S. The plumbing fixtures and fittings that apply to the calculations are toilets, urinals, lavatory faucets (both private and public), showerheads, and kitchen sink faucets 1 . Pre-rinse spray valves, dishwashers, and commercial kitchen filling operations faucets are not included in the calculations, as they are considered process water uses 1 . Therefore, the correct answer is C, urinals, public lavatory faucets, kitchen sink faucets.

The Owner’s Project Requirements (OPR) is a document that defines the goals, expectations, and performance criteria of the project, as established by the owner or the owner’s representative 1 . The OPR is one of the key deliverables of the commissioning process and serves as the basis for the design, construction, and operation of the building systems. Therefore, the priority for the Commissioning Authority (CxA) to consider when the contractor substitutes a higher efficiency piece of equipment is whether the substitution meets or exceeds the OPR. The CxA should verify that the new equipment is compatible with the OPR and does not compromise the performance, functionality, or reliability of the system. The CxA should also communicate the substitution to the owner and the design team and document the change in the commissioning plan and report.
