USGBC LEED-AP-ID+C LEED AP Interior Design + Construction (LEED AP ID+C) V4 Exam Practice Test

The Fundamental Commissioning and Verification prerequisite requires commissioning of the building’s mechanical, electrical, plumbing, and renewable energy systems and assemblies. While the building envelope is not typically commissioned, it must be included in the owner’s project requirements (OPR) and basis of design (BOD), and its design must be reviewed.

References: The LEED v4.1 reference guide for Interior Design and Construction outlines the scope of commissioning process activities, which includes the requirement for exterior enclosures to be limited to inclusion in the OPR and BOD, as well as the review of the OPR, BOD, and project design12.

Integrated decision-making involves the collaborative effort of various stakeholders in a project, from its conception through completion, to ensure the building's design serves its intended purpose effectively. In the context of placing circulation near the office perimeter next to the window wall, integrated decision-making would mean making design choices that enhance the building's performance and occupant comfort. Option A, installing blinds to increase occupant comfort, would address issues such as glare and thermal gains from the sun, which directly impact the occupants' comfort and the building's heating and cooling loads. This decision would emerge from the iterative process of identifying the unique needs and challenges of the project and making early design decisions that benefit the project both in execution and operation.

The view factor is a measure used in LEED to quantify the quality of views for occupants within a space. In the Indoor Environmental Quality Credit, Quality Views, the rating scale for view factors ranges from 0 (no view) to 5 (maximum view). In the provided diagram, it appears that the space has large windows that provide ample daylight and a view to the outside, which is a key consideration for quality views.

Although the specific outdoor view cannot be determined from the diagram alone, the presence of large windows and the potential for expansive views suggests a high view factor. View Factor 4 is typically assigned to spaces where the view window head height is at least 7 feet 6 inches above the floor, allowing occupants a clear line of sight to the outdoors. This would contribute significantly to the occupants' connection with the outdoor environment, thus scoring higher on the scale.

It is important to note that the exact view factor cannot be precisely determined without additional context regarding the actual visible content outside the windows. However, based on the scale provided and typical LEED scoring, View Factor 4 seems appropriate given the sizeable windowed areas depicted, assuming they provide a clear and unobstructed view to the exterior.References:

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.

References: The LEED v4 reference guide for Interior Design and Construction outlines the requirements for the Water Efficiency Prerequisite, Indoor Water Use Reduction, including the need for product cutsheets to document compliance with WaterSense maximum levels12.

For LEED projects, the commissioning (Cx) process is critical to ensure that all building systems are designed, installed, tested, and capable of being operated and maintained according to the owner's operational needs, including energy efficiency and sustainability goals. If a photovoltaic (PV) system is installed after the initial commissioning process has been completed, it is essential for the original Commissioning Authority (CxA) to return and either conduct or oversee the commissioning of the newly installed PV system. This ensures that the PV system is integrated properly into the building's overall energy management strategy and that it performs according to design specifications, contributing to the building's energy efficiency and sustainability goals as outlined in the Energy and Atmosphere Prerequisite, Fundamental Commissioning and Verification.References:

• LEED v4 for Building Design and Construction Reference Guide, specifically the section on Energy and Atmosphere Prerequisite, Fundamental Commissioning and Verification

The LEED Location & Transportation Credit, specifically the Surrounding Density and Diverse Uses, encourages projects to be situated in areas with a variety of services within walking distance. This credit is designed to promote walkability and reduce vehicle use, thereby lowering transportation emissions. Choosing a location within 1/2 mile of four different basic services supports these goals by providing employees with easy access to common destinations, which can be reached by walking rather than driving.

References: The LEED v4 for Interior Design and Construction reference guide details the requirements for the Surrounding Density and Diverse Uses credit, including the necessity for proximity to various services to encourage walkability1. Additionally, the LEEDuser website provides insights into achieving this credit by locating the project within a mixed-use area with accessible services2.

Within the context of the Water Efficiency Credit for Indoor Water Use Reduction in LEED, a private lavatory faucet refers to a sink that serves a non-public, individual space. This typically includes faucets in bathrooms that are designated for use by a single person or a specific occupant and are not accessible to the general public or shared among multiple users. A sink in a private office bathroom fits this definition as it is intended for the exclusive use of the occupant of the private office. In contrast, sinks in shared office restrooms, employee restrooms in retail stores, or even in private hotel room bathrooms are accessible to a broader group of users and do not meet the criterion of being a "private lavatory faucet" for the purpose of this credit.References:

• LEED v4 for Interior Design and Construction Reference Guide, particularly the section on Water Efficiency Credit, Indoor Water Use Reduction, which details the fixture types and their classifications.

For the Materials and Resources Prerequisite, Storage and Collection of Recyclables, the project team must demonstrate that they can effectively manage and divert waste from landfills. Extending the waste stream study to a minimum of 24 hours will provide a more accurate representation of the waste generated and the recyclable streams. This is essential to identify the top five recyclable waste streams, which is a requirement for this prerequisite.

References: The LEED v4 reference guide for Interior Design and Construction specifies that a waste stream audit must cover a representative time period to accurately identify the project’s waste streams1. Additionally, the LEEDuser website provides guidance on how to conduct a waste stream audit and the importance of identifying the main types of recyclable waste1.

 The Integrative Process Credit under LEED AP Interior Design + Construction V4 emphasizes the importance of a holistic approach that includes various phases of a project. The correct phases that should be included to comply with the intent of this credit are Discovery, Design and Construction, Occupancy, Operations, and Feedback. This approach ensures that sustainable strategies are integrated from the earliest stages of the project and continue through to post-occupancy to maximize performance and sustainability.

References: The LEED v4 Reference Guide for Interior Design and Construction provides detailed guidance on the Integrative Process Credit, highlighting the need for a comprehensive approach that spans the entire project timeline12.

To meet the Increased Ventilation strategy under the Enhanced Indoor Air Quality Strategies credit, the breathing zone outdoor air ventilation rates must be increased by at least 30% above the minimum rates required by ASHRAE 62.1-2010. This increase is intended to improve indoor air quality and promote a healthier indoor environment.

References: The LEED v4 reference guide for Interior Design and Construction includes this requirement as part of the strategies to enhance indoor air quality12.

For LEED Indoor Environmental Quality Credit concerning Interior Lighting, Option 1, the requirement is for 90% of building occupants to have individual lighting controls. Given that the tenant space includes 100 workstations and 10 enclosed offices intended for individual use, this means that a total of 110 workspaces require lighting control. To achieve one point, at least 90% of these occupants must have control over the lighting in their space. Therefore, the minimum number of occupants that would need individual lightingcontrols is 90% of 110, which calculates to 99 occupants (rounded down). However, as individual controls cannot be split between occupants, the actual minimum number would be 99 occupants. Option B is the closest answer to 99 without going under the required percentage.

References:Explanation of the requirements for individual lighting controls to meet the Interior Lighting Credit under Indoor Environmental Quality, indicating that 90% of building occupants must have task lighting .

Best practices for ensuring that minimum program requirements (MPRs) for LEED certification are met involve confirming these requirements early in the project lifecycle. Specifically, this confirmation should occur during the discovery phase, which is the initial stage of a project. The discovery phase involves beginning initial research and analysis, and when sufficient information has been gathered, a goal-setting workshop is held to discuss findings. Part of these findings should include checking that the project complies with the MPRs for the applicable LEED rating system. Confirming MPRs during this early phase helps in setting a clear direction for the project and ensures that all subsequent work is aligned with LEED's fundamental requirements, facilitating a smoother certification process.
