USGBC LEED AP Interior Design + Construction (LEED AP ID+C) V4 LEED-AP-ID+C Exam Dumps: Updated Questions & Answers (October 2025)

The Commissioning (Cx) agent for Energy and Atmosphere Credit, Enhanced Commissioning, must be independent of the project’s design and construction management to avoid conflicts of interest. This ensures that the Cx agent can objectively assess the project’s performance and adherence to design intentions.

References: The LEED v4 reference guide for Interior Design and Construction specifies that the Cx agent should not be an employee of the design firm to maintain independence1. Additionally, the LEED AP with Specialty Candidate Handbook outlines the importance of the Cx agent’s independence in the commissioning process2.

For the Location and Transportation Credit concerning Bicycle Facilities, the LEED v4.1 reference guide specifies that the bicycle network must connect to at least eight diverse uses. This requirement ensures that cyclists have access to a variety of services and amenities, promoting the use of bicycles as a sustainable mode of transportation.

References: This requirement is detailed in the LEED v4.1 reference guide for Interior Design and Construction under the section for Location and Transportation Credit: Bicycle Facilities123.

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.

Controlling the admission of natural light into an office space can contribute to the Indoor Environmental Quality Credit, specifically the Interior Lighting credit. This strategy aligns with the intent to provide building occupants with comfortable lighting environments that promote productivity and well-being. By managing natural light, the project can optimizethe use of daylight and reduce reliance on artificial lighting, which is a key aspect of the Interior Lighting credit.

References: The LEED v4 Reference Guide for Interior Design and Construction outlines the requirements for the Indoor Environmental Quality Credit, including strategies for interior lighting that involve the control and use of natural light12.

Occupancy numbers are a critical factor in multiple LEED credits as they directly influence calculations related to the usage and efficiency of resources and amenities. For the Location and Transportation Credit, Access to Quality Transit, knowing the occupancy numbers helps in understanding the potential demand for public transit facilities. Similarly, for the Water Efficiency Credit, Indoor Water Use Reduction, occupancy numbers are essential for accurately calculating water use and setting reduction targets. Lastly, the Indoor Environmental Quality Credit, Quality Views, considers the occupants' access to natural vistas, which is influenced by the number of people using the space. Consistent reporting of occupancy numbers ensures that the assessments for these credits are based on accurate and comparable data, reflecting the true usage patterns and needs of the building.References:

To achieve the Owner’s Project Requirements of a 45% reduction in indoor water usage, the strategy should focus on reducing process water demand. This can be done by evaluating the efficiency of kitchen and laundry equipment and optimizing their operational schedules to minimize water use. This approach targets water-intensive processes within the building, offering a significant opportunity for water savings.

References: The LEED v4 Reference Guide for Interior Design and Construction outlines strategies for reducing water use, which includes optimizing process water use as a means to achieve water efficiency within a building12.

In LEED, the Materials and Resources Credit, Building Product Disclosure and Optimization - Sourcing of Raw Materials, Option 2. Leadership Extraction Practices, encourages the use of materials sourced in a responsible manner. For the drywall in question, the value contributing to this credit can be calculated based on the percentages of recycled content and its proximity to the project site. The post-consumer recycled content (5% paper + 50% gypsum = 55% of the product) sourced from locations within the regional distance threshold (defined by LEED as within 100 miles or 160 kilometers) contributes to this credit. Therefore, 55% of the total materials cost, which is $10,000 USD, equates to $5,500 USD. This value represents the portion of the drywall cost that contributes to the credit, considering the leadership extraction practices for recycled content within a regional distance.References:

 To determine the feasibility of earning the Location and Transportation Credit for Reduced Parking Footprint, the project team needs to understand the local zoning code’s requirements for the minimum number of parking spaces. This is because the credit aims to minimize the impact on the environment by reducing parking capacity to meet but not exceed local zoning requirements1.

Discussions on LEEDuser forums about the Reduced Parking Footprint credit, which clarify the need to comply with local zoning requirements and not exceed them1.

Option 2 of the Location and Transportation Credit, Surrounding Density and Diverse Uses, requires that the project’s main entrance be within a 1/2-mile walking distance of at least seven operational and publicly accessible uses. The existing fast-food restaurant without a drive-in service, being only 1/8 mi. away, meets the criteria for proximity and is considered a diverse use under this credit1.

The LEED requirements for Indoor Environmental Quality, Thermal Comfort, necessitate that at least 50% of individual occupant spaces have individual thermal comfort controls. This allows occupants to adjust the thermal conditions in their immediate environment to suit their personal comfort levels.

References: The LEED v4 reference guide for Interior Design and Construction details the need for individual thermal comfort controls in at least half of the occupant spaces to promote occupant comfort and well-being1. Additionally, resources like LEEDuser provide guidance on implementing these requirements in practice2.
