QUESTION: 113

Which of the following plumbing fixtures apply to the calculations in Water Efficiency Prerequisite, Indoor Water Use Reduction?

Toilets, urinals, pre-rinse spray valves
Toilets, private lavatory faucets, dishwashers
Urinals, public lavatory faucets, kitchen sink faucets
Urinals, showerheads, commercial kitchen filling operations faucets

Answer(s): C

Explanation:

According to the LEED v4: 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. Pre-rinse spray valves, dishwashers, and commercial kitchen filling operations faucets are not included in the calculations, as they are considered process water uses. Therefore, the correct answer is C, urinals, public lavatory faucets, kitchen sink faucets.

QUESTION: 114

Which of the following strategies will aid in reducing indoor water use?

Design drip irrigation for landscape
Use high-efficiency HVAC systems
Exclude janitor closets in the building
Optimize consumption of showerheads

Answer(s): D

Explanation:

According to the LEED v4: Building Design + Construction Guide, one of the strategies to reduce indoor water use is to optimize the consumption of showerheads by selecting fixtures that have a flow rate lower than the baseline of 2.0 gallons per minute (gpm) at 80 psi, or a local equivalent for projects outside the U.S. This can help the project achieve the Water Efficiency Prerequisite, Indoor Water Use Reduction, and the Water Efficiency Credit, Indoor Water Use Reduction, by reducing the aggregate water consumption from plumbing fixtures and fittings by at least 20% from the baseline. The other choices are not strategies to reduce indoor water use, because:
Designing drip irrigation for landscape is a strategy to reduce outdoor water use, not indoor water use.
Using high-efficiency HVAC systems is a strategy to reduce energy use, not water use, although it may have some indirect water savings by reducing the cooling tower water use.

Excluding janitor closets in the building is not a feasible or practical strategy, as janitor closets are necessary for cleaning and maintenance purposes, and may also be required by codes or standards.

QUESTION: 115

Water Efficiency Prerequisite, Outdoor Water Use Reduction, Option 2. Reduced Irrigation, requires that a project's landscape water requirement be reduced by what percentage from the calculated baseline for the project site's peak watering month?

Answer(s): C

Explanation:

According to the LEED v4: Building Design + Construction Guide, the Water Efficiency Prerequisite, Outdoor Water Use Reduction, Option 2. Reduced Irrigation, requires that a project's landscape water requirement be reduced by at least 30% from the calculated baseline for the project site's peak watering month. The baseline is determined by the Environmental Protection Agency (EPA) WaterSense Water Budget Tool, or a local equivalent for projects outside the U.S. The reduction must be achieved through plant species selection and irrigation system efficiency.

QUESTION: 116

What document allows a LEED AP to register a project and sign the Certification Agreement?

Owner Confirmation of Agent Authority
Architect Code of Professional Conduct
Commissioning (Cx) Agent Construction Permit
LEED AP Standard Form of Agreement Between Owner and Architect

Answer(s): A

Explanation:

According to the LEED v4: Building Design + Construction Guide, the document that allows a LEED AP to register a project and sign the Certification Agreement is the Owner Confirmation of Agent Authority. This form is used to validate the Certification Agreement when it is signed by someone other than the owner, such as a LEED AP. It provides proof that the owner accepts the conditions in the Certification Agreement and authorizes the LEED AP to act as the owner's agent for the purpose of LEED project certification. The other choices are not relevant documents for this purpose.
