Question 1 Domain 2Planning and Scoping

An owner has expressed concerns to the LEED AP about the costs associated with the integrative process. How can the LEED AP relieve the owner's concerns?

AThe LEED AP should explain to the owner that since the integrative process is not a prerequisite, it can be dropped from the project thus cutting back project costs

BThe LEED AP should explain that while the first costs and the design fees will be higher due to the integrative
process, the operational savings will make up for the extra costs

CThe LEED AP should explain that the integrative process can easily be postponed and reconsidered until after
the design for the construction phase, when it will most likely save costs for the project

DThe LEED AP should explain that the integrative process reduces costs by avoiding delays associated with design changes during the construction document phase and reducing change orders during construction

Correct Answer: D

Explanation

The integrative process is a strategy that can lead to both immediate and long-term cost savings. By engaging in early analysis of the interrelationships among systems, the project team can identify unique opportunities and challenges.This early engagement helps to optimize the design, which can reduce the time and cost associated with making design changes later in the project and minimize the need for change orders during construction1.

Question 2 Domain 2Planning and Scoping

Which strategy could be incorporated into the negotiations of a lease agreement between a tenant and building owner

to contribute towards earning a LEED credit?

AA lease renewal option prior to 10 years

BDiscounted parking fees for first year of lease

CAn energy payment plan where the tenant pays a flat rate on utilities through the building owner

DEnergy purchase through the building owner's campus facility that produces renewable power to Green-e standards

Correct Answer: D

Explanation

Incorporating a strategy where the tenant purchases energy from the building owner's campus facility that produces renewable power to Green-e standards can contribute towards earning a LEED credit. This is because it supports the use of renewable energy, which is a key component of LEED's sustainable energy criteria.

Question 3 Domain 2Planning and Scoping

For the achievement of Materials and Resources Credit, Interiors Life Cycle Impact Reduction, Option 1. Interior Reuse, how are hazardous materials accounted for in the calculation?

AIncluded in the numerator only

BIncluded in the denominator only

CIncluded in both the numerator and denominator

DExcluded from both the numerator and denominator

Correct Answer: D

Explanation

For the LEED AP ID+C V4 Materials and Resources Credit, under Interiors Life Cycle Impact Reduction, Option 1: Interior Reuse, hazardous materials that are remediated as part of the project must be excluded from the calculation. This ensures that the assessment of reused materials does not inadvertently promote the retention of hazardous substances in the interior space.

Question 4 Domain 3Fieldwork and Evaluation

A project's installed water fixtures do not exceed WaterSense maximum levels. Which compliance path should the LEED AP select under Water Efficiency Prerequisite, Indoor Water Use Reduction, and what type of documentation is required to demonstrate compliance with this path?

ACompliance Path 1: Prescriptive Achievement; product cutsheets

BCompliance Path 2: Usage-Based Calculation; indoor water use calculations

CCompliance Path 1: Prescriptive Achievement; indoor water use calculations

DCompliance Path 2. Usage-Based Calculation; prescriptive compliance confirmation

Correct Answer: A

Explanation

When a project's installed water fixtures do not exceed WaterSense maximum levels, the appropriate compliance path under the Water Efficiency Prerequisite for Indoor Water Use Reduction is Compliance Path 1: Prescriptive Achievement. This path requires product cutsheets as documentation to demonstrate compliance. The product cutsheets serve as verification that the installed fixtures meet the WaterSense labeling requirements and do not exceed the maximum flow rates established by WaterSense standards.

Question 5 Domain 3Fieldwork and Evaluation

For Energy and Atmosphere Prerequisite, Fundamental Commissioning (Cx) and Verification, the final Cx report must include the

ACorrective Action Plan

BThermal Comfort Survey

Cfunctional performance tests

Dmechanical drawings showing all equipment installed

Correct Answer: C

Explanation

For the Energy and Atmosphere Prerequisite, Fundamental Commissioning and Verification, the final commissioning (Cx) report must include the results of functional performance tests.These tests ensure that the building's energy-related systems are installed, calibrated, and perform according to the owner's project requirements, the basis of design, and construction documents1.
