USGBC LEED AP Building Design + Construction (LEED v5 AP BD+C) LEED-AP-BD+C Exam Dumps: Updated Questions & Answers (September 2026)

According to the LEED BD+C Minimum Program Requirements (MPRs), a project ' s gross floor area must be no less than 1% of the gross land area within the LEED project boundary. This requirement ensures that the project includes a building component that is significant enough to warrant LEED certification, distinguishing it from projects that are primarily land developments without substantial building structures. ​

To comply with Indoor Environmental Quality Credit, Thermal Comfort, the standard that needs to be followed is ASHRAE 55-2010, Thermal Environmental Conditions for Human Occupancy, with errata or a local equivalent1.This standard specifies the combinations of indoor thermal environmental factors and personal factors that will produce thermal environmental conditions acceptable to a majority of the occupants within the space2.The standard also provides methods for measuring and evaluating thermal comfort, as well as guidance for design, operation, and maintenance of thermal comfort systems2.References:Thermal comfort;ASHRAE 55-2010

According to theLEED V5Reference Guide for Building Design and Construction, no smoking signage must be placed within 10 feet (3 meters) of every building entrance, except for alarmed emergency exits. This applies to both the main entrance and the service entrances, regardless of their location or frequency of use.The signage is intended to communicate the no-smoking policy to occupants and visitors and prevent environmental tobacco smoke from entering the building.References: EQPrerequisite Environmental Tobacco Smoke Control,LEED V5Reference Guide for Building Design and Construction123

Detailed Explanation:

For the Brownfield Remediation option under the High-Priority Site credit, the project site must include contaminated soil or groundwater requiring cleanup to improve environmental conditions. This credit incentivizes the redevelopment of previously unusable or hazardous sites, helping to promote environmental restoration and sustainable land use.

According to theLEED V5Reference Guide for Building Design and Construction, the calculations for Quality Views must include the following variables: window size and configuration, glazing factor, window head height, distance of the window from the floor, permanent interior obstructions, and exterior obstructions. Ceiling heights, building furniture, and movable partitions are not required to be included in the calculations.

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 highly reflective paving materials that have a high solar reflectance index (SRI), which measures the ability of a surface to reflect solar radiation and stay cool. However, over time, the paving materials can accumulate dirt and dust, which can lower their reflectance and increase their heat absorption. Therefore, a facility manager cleaning highly reflective paving material is reducing the heat island effect by restoring the reflectance and cooling potential of the surface12.

LEED v5 MRc2 explicitly provides points for tracking greenhouse-gas-producing construction activities under the construction-stage life-cycle module A5. The credit focuses on actual fuel and utility usage associated with contractor jobsite operations. One pathway awards a point for tracking all contractor fuel and utility consumption, while the higher pathway extends tracking to contractor and subcontractor jobsite operations. Importantly, LEED does not require the project to prove that construction emissions were reduced in order to earn these tracking points; accurate measurement and carbon accounting are the principal requirements. Therefore, simply developing a reduction plan, as described in Option C, is insufficient. The AGC Playbook may provide useful industry guidance, but adherence to it is not the stated credit requirement. Option B correctly identifies the required operational data that must be documented.

The system boundary that a building life cycle analysis must be defined to account for is the cradle-to-grave stage, which includes the production, construction, use, and end-of-life stages of the building. This stage covers all the inputs and outputs of the building system, such as materials, energy, water, emissions, waste, and maintenance.

For Energy and Atmosphere Credit, Advanced Energy Metering, the minimum amount of time that the metering system should store data is36 months.This is to ensure that the data can be used for long-term analysis and verification of energy performance1.Thecredit also requires that the metering system be capable of transmitting data to a remote location and reporting energy use at least hourly1.References:Advanced energy metering

Graywater collected from appropriate building sources and treated on-site is suitable for a reuse-ready system because it represents a recurring project-generated supply that can offset potable-water demand. The project can design dedicated collection piping, storage, treatment, controls, and separate nonpotable distribution for uses such as toilet flushing, irrigation, or cooling-tower makeup. Utility-supplied desalinated water remains externally supplied water and does not create an on-site reuse cycle. Harvested rainwater is also a valuable alternative source, but its availability varies with climate, roof area, rainfall patterns, and storage capacity. Graywater is typically linked more consistently to building occupancy and wastewater generation. The system must comply with public-health regulations, plumbing codes, cross-connection controls, treatment requirements, and water-quality monitoring.
