LEED-AP-BD+C Exam Dumps - LEED AP Building Design + Construction (LEED v5 AP BD+C)

The metal base, 20% of product by weight, which do not contain heavy metals and is not plated with hexavalent chromium, contributes toward Materials and Resources Credit, Furniture and Medical Furnishings. This is because it meets the criteria of Option 1: Minimal Chemical Content, which requires that all components that constitute at least 5%, by weight, of a furniture or medical furnishing assembly must contain less than 100 ppm of at least four of the five chemical groups listed in the option. The other portions of the product either do not meet the 5% weight threshold (wheels), or contain chemicals that are restricted by Option 1 (fabric, armrests).

In theIntegrative Process, theOwner’s Project Requirements (OPR)should be created during the predesign phase and edited throughout the project (C). The OPR documents the owner’s goals and objectives, guiding design decisions to align with these priorities. Updating the OPR as necessary ensures that project design and construction remain aligned with the owner’s vision and LEED requirements.

TheLEED Accredited Professional (LEED AP)plays aconsultative rolein helping theowner develop the Owner’s Project Requirements (OPR).

TheOPR defines project goals, includingenergy efficiency, sustainability, and occupant comfort.

It isthe owner’s responsibility to define the OPR, while theLEED AP provides guidance and technical expertise.

Thedesign team and commissioning authority (CxA) reference the OPRthroughout the project.

A LEED APdoes not author, oversee, or publishthe document, but ensures thatLEED goals align with the project’s sustainability vision.

Detailed Explanation:

Preliminary energy modeling focuses on the building’s massing, orientation, thermal comfort ranges, and energy supply sources. Plug and process loads are typically omitted at this stage as they are highly variable and depend on specific occupant behavior and equipment usage. LEED focuses on the building’s core energy performance during preliminary analysis.

An intensive vegetated roof is a roof that has a thick layer of soil and plants that provide shade, evapotranspiration, and stormwater management. It can reduce the heat island effect by lowering the surface and air temperature of the roof and the surrounding area. Artificial turf grass does not reduce the heat island effect because it is not a living plant and does not provide cooling benefits. A steep sloped roof with initial SRI of 35 does not meet the minimum requirement of 39 for Option 1 or 32 for Option 2 of the Heat Island Reduction credit. A low sloped roof with initial SRI of 64 exceeds the minimum requirement of 82 for Option 1 or 64 for Option 2, but it is not the best option among the choices because it only reflects solar radiation and does not provide other benefits such as shading, evapotranspiration, and stormwater management.References:

According to theLEED V5: Building Design + Construction Guide, the Energy and Atmosphere Prerequisite, Fundamental Commissioning and Verification, requires the project to hire a Commissioning Authority (CxA) to oversee the commissioning process for the mechanical, electrical, plumbing, and renewable energy systems and assemblies. The CxA must have documented commissioning authority experience in at least two building projects, and must not be an employee of the design or construction firms, although they may be contracted through them.The CxA must report the results, findings, and recommendations directly to the owner1.

One of the required responsibilities for the CxA to achieve the prerequisite is to verify installation and performance of the commissioned systems.This includes conducting siteobservations and spot-checking of equipment installation, performing functional performance testing of the systems, verifying system performance by reviewing testing and balancing reports, and preparing a summary commissioning report of the activities and results1.

The other choices are not required responsibilities for the CxA to achieve the prerequisite, but they are additional responsibilities for the CxA to achieve the Energy and Atmosphere Credit, Enhanced Commissioning, which goes beyond the prerequisite by including more systems, more verification activities, and more documentation.These additional responsibilities are2:

Verify that training requirements are completed. This includes reviewing training plans, agendas, and materials, and verifying that the training delivery and documentation are completed and consistent with the owner’s project requirements (OPR).

Develop systems manual for the commissioned systems. This includes compiling and reviewing the systems manual that provides the necessary information for operating and maintaining the commissioned systems.

Review contractor submittals for the commissioned systems. This includes reviewing the design intent and basis of design documentation, and providing feedback on the contractor submittals related to the commissioned systems, such as shop drawings, product data, and samples.

A split review is an optional review process that allows project teams to submit the design and construction portions of their projects separately. This can help teams determine if the project is on track to achieve LEED certification at its preferred level, and identify any issues or clarifications needed before the final review. A split review also reduces the documentation burden and review time for the construction review12.

LEED v5 makes climate resilience an explicit early-project requirement through IPp1: Climate Resilience Assessment. Projects must identify observed, projected, and future natural hazards that could affect the project site and building function and then prioritize hazards for response through design strategies. Examples include drought, extreme heat and cold, flooding, hurricanes, sea-level rise, wildfire, and other site-relevant hazards. Conducting this assessment early allows the project team to understand exposure, sensitivity, adaptive capacity, vulnerability, and potential impacts before major design decisions become fixed. Reduced construction cost may sometimes result from integrated planning, but it is not the principal climate-resilience outcome. Renewable-energy integration is important for decarbonization but addresses only part of project resilience. Therefore, Option C most directly reflects the LEED v5 Climate Resilience Assessment framework.
