LEED-AP-BD+C USGBC LEED AP Building Design + Construction (LEED AP BD+C) Free Practice Exam Questions (2025 Updated)

Installing a vegetative roofing system is the best option to address the potential glare resulting from a project’s highly reflective roof. A vegetative roofing system, also known as a green roof, is a roof that is partially or completely covered with vegetation and a growing medium, planted over a waterproofing membrane. A vegetative roofing system can reduce the reflectivity of the roof surface and mitigate the glare impact on the surrounding environment. It can also provide other benefits, such as reducing heat island effects, improving stormwater management, enhancing biodiversity, and increasing roof insulation. Therefore, option A is the correct answer. The other options are not as effective or desirable as installing a vegetative roofing system. Changing the design to reduce the amount of roofing area (option B) may not be feasible or desirable, as it may compromise the project’s program or performance. Changing the roofing material to a dark material to eliminate the issue (option C) may reduce the glare, but it will also increase the heat absorption and emission of the roof, contributing to heat island effects and increasing cooling loads. Increasing the parapet height (option D) may block some of the glare, but it will also increase the material and construction costs, and it may not be sufficient to prevent glare from all angles. For more information on vegetative roofing systems and their benefits, you can refer to the LEED v4 Reference Guide for Building Design and Construction1 or the Green Roofs for Healthy Cities website2.

The percentage of recycled content contributing to the credit is calculated based on the value of the recycled content relative to the total construction cost. The combined value of recycled content here is $1 million (post-consumer) + $1 million (pre-consumer) = $2 million. The percentage is then calculated as:

2,000,00010,000,000×100=20%\frac{2,000,000}{10,000,000} \times 100 = 20\%10,000,0002,000,000​×100=20%

Therefore, the recycled content accounts for 20% of the total material value for the project, contributing to the Materials and Resources Credit: Building Product Disclosure and Optimization - Sourcing of Raw Materials.

The only stage of LEED for Neighborhood Development certification that is eligible for points under Building Design and Construction: New Construction, Location and Transportation Credit, LEED for Neighborhood Development Location, is LEED for Neighborhood Development Pilot, Stage 3 LEED for Neighborhood Development Certified Project. This is because the credit requires that the project be located within the boundary of a development that has achieved certification under LEED for Neighborhood Development (either Stage 2 or Stage 3 under the Pilot or 2009 rating systems, or Certified Plan or Certified Project under the LEED v4 rating system)1 The other stages listed in the question are either conditional approvals or pre-reviews that do not guarantee certification23 References: 1: LEED v4 Reference Guide for Building Design and Construction, Location and Transportation Credit: LEED for Neighborhood Development Location, page 460. 2: LEED for Neighborhood Development Location – Above Green 3 3: LEED v4: Building Design + Construction Guide - U.S. Green Building Council 1

According to the LEED v4 Reference 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.

According to the LEED Campus Guidance, the campus approach allows projects that share a single location and site attributes to achieve separate LEED certification for each project, building space, or group on the master site. The campus approach can be used for certain credits that are influenced by the site conditions and infrastructure, such as Sustainable Sites credits. The LEED Campus Guidance provides a list of eligible credits for the campus approach, which includes the following Sustainable Sites credits1:

•Site Assessment

•Site Development - Protect or Restore Habitat

•Open Space

•Rainwater Management

•Heat Island Reduction

•Light Pollution Reduction

Therefore, Heat Island Reduction, Light Pollution Reduction, and Rainwater Management are Sustainable Sites credits that are eligible to be used as a campus approach. Places of Respite, Site Master Plan, and Direct Exterior Access are not Sustainable Sites credits, but other credits or prerequisites that are not eligible for the campus approach1.

At the time of registering a project in LEED Online, Regional Priority credits are determined based on the project’s longitude and latitude. Regional Priority credits are bonus points that reward projects for addressing the environmental, social, and public health issues that are most relevant to their location1. The project team must enter the project’s address and confirm the precise location using the Google Maps interface in LEED Online2. The longitude and latitude coordinates are then used to identify the Regional Priority credits that are applicable to the project2. The project can earn up to four Regional Priority points by achieving the base credits that correspond to the Regional Priority credits1. References:

This rating system is suitable for projects where the developer controls the design and construction of the entire core and shell base building, but has no control over the design and construction of the tenant fit-out. Since the building will have a data center and retail stores in the future, but these are not the primary function of the entire building, LEED BD+C: Core & Shell is more appropriate than LEED BD+C: Data Centers or LEED BD+C: Retail.

The minimum scope of analysis for a product-specific declaration is cradle-to-gate, which means from raw material extraction to the factory gate. This option requires the use of at least 20 different permanently installed products sourced from at least five different manufacturers that have product-specific declarations.

According to the LEED v4: Building Design + Construction Guide, the Water Efficiency Prerequisite, Indoor Water Use Reduction requires the project to reduce the aggregate water consumption from plumbing fixtures and fittings by at least 20% from the baseline. The baseline water consumption is determined by the Energy Policy Act of 1992 and subsequent rulings by the Department of Energy, or a local equivalent for projects outside the U.S. The plumbing fixtures and fittings that apply to the calculations are toilets, urinals, lavatory faucets (both private and public), showerheads, and kitchen sink faucets1. Pre-rinse spray valves, dishwashers, and commercial kitchen filling operations faucets are not included in the calculations, as they are considered process water uses1. Therefore, the correct answer is C, urinals, public lavatory faucets, kitchen sink faucets.

The renewable energy option is economically feasible if the present value of the utility cost savings over the lifetime of the system is greater than or equal to the present value of the higher initial cost of the system. This means that the system will pay for itself and generate net savings in the long run. The utility cost savings depend on the amount of energy produced by the solar thermal panel, the price of natural gas, and the inflation rate. The higher initial cost depends on the size, type, and installation of the solar thermal panel.

USGBC’s vision for using LEED internationally is to promote green building practices that are globally applicable, locally relevant, and culturally sensitive1. To achieve this vision, USGBC provides opportunities for alternative compliance paths (ACPs) that meet the unique needs of a particular region, such as climate, codes, standards, market conditions, and priorities2. ACPs are modifications or additions to existing LEED credits or prerequisites that recognize regional differences and allow for more flexibility and applicability of LEED3. ACPs are developed by USGBC in collaboration with local green building councils, experts, and stakeholders, and are reviewed and approved by the LEED Steering Committee3. ACPs are available for various regions and countries, such as China, India, Brazil, Europe, and Canada2.

Data centers are buildings that house computer systems and associated components, such as servers, storage devices, and network equipment. They typically operate 24/7 and do not have regular commuting patterns of occupants. Therefore, they can exclude weekend transit service from the transit service level calculations for the Location and Transportation Credit, Access to Quality Transit12. This credit aims to encourage development in locations that are served by high-quality transit, which reduces greenhouse gas emissions, transportation costs, and automobile dependence.

Average number of occupants standing or seated

To identify the regularly occupied spaces on a project, the LEED consultant should consider the average number of occupants standing or seated in each space, as this is the criterion used by the LEED Reference Guide for Green Building Design and Construction, 20091. Regularly occupied spaces are defined as areas where workers are seated or standing as they work (or perform regular tasks) inside a building2. The typical duration of occupancy in each space per day is not necessarily relevant, as some spaces may be used intermittently but still qualify as regularly occupied2. The rate of outdoor air provided per person and the fire ratings of installed wall and ceiling assemblies are not related to the definition of regularly occupied spaces, but rather to other credits such as Indoor Environmental Quality or Fire and Life Safety.

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

This option allows the project to comply with the minimum energy performance prerequisite by following the prescriptive recommendations of the ASHRAE 50% Advanced Energy Design Guide (AEDG) for the applicable building type and climate zone1. This option simplifies the decision making and analysis process by providing clear and specific guidance on how to achieve 50% energy savings compared to the baseline standard2. This option also reduces the need for energy modeling and documentation, which can save time and money for the project3.

This is because:

A building automation system (BAS) is a system that controls and monitors various aspects of a building’s operation, such as lighting, heating, ventilation, air conditioning, security, fire alarm, and energy management1.

A BAS can allow programmable load control (PLC), which is the ability to adjust the power consumption of devices or equipment based on a schedule, a sensor, or an event2. PLC can help reduce the energy demand and cost of a building by optimizing the use of resources and avoiding unnecessary or wasteful consumption3.

The LEED AP BD+C V4 credit for Demand Response requires that buildings have a demand response program that can respond to changes in electricity prices or supply by reducing or shifting the demand for electricity4. A BAS can enable such a program by allowing PLC and other features that can modulate the power usage of devices or equipment in response to market signals or internal conditions.

Therefore, installing a BAS to allow PLC can help achieve the Energy and Atmosphere Credit for Demand Response by reducing the energy demand and cost of a building.

According to the LEED v4: Building Design + Construction Guide, the bicycle network must connect to a rapid transit stop that is within 3 mi. (5 km) biking distance of the project boundary. This is one of the options to meet the requirement for Option 1: Bicycle Network and Storage. The other options are to connect to at least 10 diverse uses or to connect to a school or employment center that is within 3 mi. (5 km) biking distance of the project boundary. References: LEED v4: Building Design + Construction Guide, Location and Transportation Credit: Bicycle Facilities, Option 1: Bicycle Network and Storage1

If a transporter lacks chain-of-custody (CoC) certification for certified wood products, the design team should recalculate the percentage of certified wood and classify the affected wood as non-certified (B). This approach follows LEED's requirements for accurate reporting on certified materials. LEED requires all certified wood to maintain CoC certification from the forest to the project site, so any deviation affects credit calculations. Submitting a CIR (A) isn’t needed as the LEED rules are clear on this matter, and removal (D) may not be feasible or cost-effective.

Peak-hour is a term used to describe the time period when the traffic noise is highest, usually during morning and evening rush hours. Peak-hour noise level is measured by the equivalent continuous sound level (Leq), which is an energy-average of the noise level over a specified sample time. For minimum acoustic performance, LEED requires projects to implement acoustic treatment and other measures to minimize noise intrusion from exterior sources for high-noise sites (peak-hour Leq above 60 dBA during school hours).
