USGBC Updated LEED-AP-BD+C Exam Questions and Answers by aarya

ForLEED BD+C Energy and Atmosphere (EA) Prerequisite: Fundamental Commissioning and Verification, theCxA is responsible for verifying that building systems are properly installed and functioning correctly.

This ensures compliance with the Owner’s Project Requirements (OPR)andbasis of design (BOD).

Developing a systems manual (Option D) is required for Enhanced Commissioning, not Fundamental Commissioning.

Reviewing the building after 10 months (Option B) is also part of Enhanced Commissioning, not Fundamental Commissioning.

Training verification (Option C) is beneficial but not a core responsibility for Fundamental Commissioning.

Verifying installation and performance (Option A) is the primary requirement for the CxA under Fundamental Commissioning.

A vegetated shading structure is an example of a nonroof measure for Sustainable Sites Credit, Heat Island Reduction. The heat island effect is the phenomenon of urban areas having higher air temperatures than surrounding rural areas due to the absorption and emission of heat by human-made surfaces, such as buildings, roads, and pavements. The heat island effect can have negative impacts on the environment, human health, and energy consumption. One of the strategies to reduce the heat island effect is to use nonroof measures that provide shade, reflectivity, or evapotranspiration for at least 50% of the site hardscape, such as parking lots, walkways, plazas, and courtyards1. A vegetated shading structure is a type of nonroof measure that consists of a trellis or pergola that supports climbing plants or vines that provide shade and cooling for the underlying surface. A vegetated shading structure can also enhance the aesthetic and ecological value of the site2.

The other options are not examples of nonroof measures for Sustainable Sites Credit, Heat Island Reduction. A playground with artificial turf is not a nonroof measure, but a roof measure, as it is considered as part of the building envelope. Artificial turf is also not a compliant roof measure, as it does not meet the minimum solar reflectance index (SRI) or vegetated roof requirements1. A shade structure with a three-year aged SRI value of 0.2 is not a compliant nonroof measure, as it does not meet the minimum SRI value of 29 for nonroof surfaces1. A paving material with a three-year aged SRI value of 0.2 is also not a compliant nonroof measure, as it does not meet the minimum SRI value of 29 for nonroof surfaces1.

Automated door systems improve physical accessibility by reducing the strength, reach, and dexterity required to enter or move through a building. They particularly benefit wheelchair users, people using walkers or crutches, occupants carrying equipment, and individuals with limited upper-body mobility. Lactation rooms support health, privacy, and inclusion, but they address a specific occupant need rather than general physical access. Visual contrast assists people with low vision by making doors, floors, walls, controls, and circulation features easier to distinguish, but automated doors more directly remove a physical barrier to entry. The selected systems must provide accessible controls, appropriate opening times, sufficient clear width, safe sensor operation, and continuous accessible routes. This approach supports LEED v5’s quality-of-life emphasis on health, equity, and inclusive occupancy.

The document that details ideas, concepts, and criteria that are essential for a building ' s success is theOwner ' s Project Requirements (OPR). The OPR outlines the goals, expectations, and criteria from the owner’s perspective, setting a foundational vision for the project. It is used in LEED AP ID+C certification as a guideline for aligning design and construction decisions with the owner ' s objectives. The Basis of Design (BOD) then takes the OPR’s high-level goals and translates them into technical requirements. Both documents support integrated project delivery by helping ensure design aligns with the owner ' s goals, but the OPR specifically details what the owner considers essential.
