Free Practice Questions for USGBC LEED-AP-BD+C Exam

This option requires the project to calculate the contributing value of the fixture by multiplying the cost of the fixture by the percentage of recycled content by weight1. Since the shades are 10% of the overall weight of the fixture and are 50% post-consumer recycled content, the contributing value of the fixture is:

$1,500 x 10% x 50% = $75

For LEED BD+C Location and Transportation (LT) Credit: Sensitive Land Protection, Option 2, projects must be located outside of high-risk flood zones.

LEED aligns with FEMA’s 100-year floodplain definition, meaning projects must be located outside areas with a 1% or greater chance of flooding annually.

Projects in flood-prone areas require additional mitigation measures.

The other options (B, C, and D) use incorrect flood frequency thresholds that do not align with LEED standards.

LEED requires projects to be entirely outside a 100-year floodplain (1% annual chance of flooding).

Large commercial buildings are most often dominated by internal loads, which are the heat gains or losses from people, equipment, lighting, and other sources inside the building. Internal loads can affect the heating and cooling loads and the energy consumption of the building. Therefore, reducing internal loads can improve the building’s energy efficiency and performance. References:

Providing a vehicular access drive that is less than 16 ft. (5 m) in width is considered an acceptable minor improvement within the wetland buffer for Location and Transportation Credit, Sensitive Land Protection. This credit requires avoiding development on land that meets one or more of the following criteria: prime farmland, floodplains, threatened or endangered species habitat, water bodies, wetlands, or land within 100 feet (30 meters) of these water bodies or wetlands1. However, the credit allows minor improvements within the wetland buffer if they are necessary for the project and have minimal environmental impact2. Examples of minor improvements include trails, boardwalks, stormwater outfalls, and utility crossings2. References:

The correct sequence for LEED certification is: Choose Rating System, Register, Submit documentation through LEED Online, Review, Certify (C). Projects begin by selecting the appropriate LEED rating system, then register with USGBC, followed by documentation submission for review. After review, certification is granted based on achieved points. This structured approach ensures accurate and consistent compliance with LEED standards.

Interior paint must always be included in Materials and Resources credits. This is because interior paint is considered as a permanently installed product, which is defined by the LEED v4 Reference Guide for Building Design and Construction as "a product that is installed in a project permanently or semi-permanently, such that removal would require demolition or substantial renovation."1 Permanently installed products must be included in the calculations for the following Materials and Resources credits: Building Life-Cycle Impact Reduction, Building Product Disclosure and Optimization - Environmental Product Declarations, Building Product Disclosure and Optimization - Sourcing of Raw Materials, and Building Product Disclosure and Optimization - Material Ingredients.1 The other options are not always included in Materials and Resources credits. Faucets (option A) and fire suppression systems (option D) are considered as mechanical, electrical, and plumbing components, which are excluded from the scope of Materials and Resources credits unless they are specifically addressed by the credit requirements.1 Furniture (option B) is considered as a non-permanently installed product, which is optional to include in Materials and Resources credits, except for the Building Product Disclosure and Optimization - Material Ingredients credit, where furniture must be included if it is within the project scope.1 References: LEED v4 Reference Guide for Building Design and Construction, p. 5791; LEED v4 Reference Guide for Building Design and Construction, p. 5801; LEED v4 Reference Guide for Building Design and Construction, p. 5811; LEED v4 Reference Guide for Building Design and Construction, p. 5821; LEED v4 Reference Guide for Building Design and Construction, p. 5831

For LEED BD+C Materials and Resources (MR) Credit: Building Product Disclosure and Optimization, teams must prioritize material selection based on environmental and sustainability attributes.

Including material requirements in project specifications ensures that all contractors, suppliers, and stakeholders follow the necessary sustainability criteria.

Selecting locally sourced materials (Option B) is beneficial, but it is not the primary focus of this credit.

Whole-building life-cycle analysis (Option C) is related to a different LEED credit (MR Credit: Whole-Building Life-Cycle Impact Reduction).

Procuring materials directly from raw suppliers (Option D) is not a LEED requirement and does not ensure compliance with disclosure and optimization requirements.

Option A is the correct choice because defining sustainability criteria in specifications helps ensure LEED-compliant materials are used throughout the project.

Natural daylighting can reduce the electricity use for artificial lighting, which is one of the major components of operational energy cost for buildings. By having the lights off or dimmed when sufficient daylight is available, the project can save energy and money. The other options are not necessarily true or relevant for natural daylighting. Heat gain and passive solar heating depend on the orientation, shading, and insulation of the windows, not just the amount of daylight. Reduction in lighting fixture use may reduce re-lamping, but that is not a significant factor in operational energy cost compared to electricity use.

According to the LEED v4: Building Design + Construction Guide, the location of CO2 sensors in naturally ventilated spaces to comply with the Indoor Environmental Quality Prerequisite, Minimum Indoor Air Quality Performance is between 3 ft. and 6 ft. (1 m and 2 m) above the floor. This is one of the requirements for Option 2. Naturally Ventilated Spaces, which applies to projects that rely on natural ventilation for all or part of the occupied spaces. The CO2 sensors must be located in each zone with natural ventilation openings, and must be capable of generating an alarm when the CO2 concentration exceeds the design value1.

The other choices are not correct, because:

At least 6 ft. (2 m) above the floor is the location of CO2 sensors in mechanically ventilated spaces, not naturally ventilated spaces1.

At least 3 ft. (1 m) away from windows is a general guideline for locating CO2 sensors, but it does not specify the height above the floor2.

On the ceiling 3 ft. (1 m) away from adjacent walls is not a recommended location for CO2 sensors, as it may not reflect the actual CO2 concentration at the breathing zone of the occupants2.

Private lavatory faucets are eligible for a WaterSense label, provided they meet EPA’s specifications for water efficiency and performance, and are backed by independent, third-party certification. Tankless toilets, waterless urinals, and public lavatory faucets are not eligible for a WaterSense label because they are not included in the product categories that WaterSense covers. WaterSense currently labels products in the following categories: tank-type toilets, water-using urinals, private lavatory faucets, showerheads, irrigation controllers, spray sprinkler bodies, and pre-rinse spray valves.
