LEED-AP-BD+C USGBC LEED AP Building Design + Construction (LEED v5 AP BD+C) Free Practice Exam Questions (2026 Updated)

The Indoor Environmental Quality Credit, Interior Lighting, requires the project team to provide individual occupant lighting control for at least 90% of the individual occupant spaces, or at least 50% of the shared multi-occupant spaces. The lighting control must enable occupants to adjust the lighting to suit their individual tasks and preferences, and must have at least three lighting levels, excluding off1. Therefore, a three level (on, 25%, off) lighting control meets the requirements of this credit, while a two level (on, off) lighting control does not. A three level (on, 50%, off) or a three level (on, 75%, off) lighting control may also meet the requirements, depending on the lighting power density and the daylight availability in the space2.

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.References: EA Credit Optimize Energy Performance, EQ Credit Daylight,LEED V5Reference Guide for Building Design and Construction123

Detailed Explanation:

The project must meet the more stringent requirement, which in this case is 500 CFM (14.1 CMM) as per the local code. LEED Enhanced Indoor Air Quality prerequisites and credits prioritize compliance with the highest applicable ventilation standards to improve indoor air quality and occupant comfort.

LEED v5 MRc3: Low-Emitting Materials evaluates VOC emissions from applicable interior products and materials. Under the adhesives and sealants product category, LEED specifically includes interior adhesives and sealants that are wet-applied on-site, including products used to install air or vapor barrier membranes and floor-setting materials. This directly corresponds to Option B. A non-structural wall is evaluated principally within the applicable wall-material category, while wet-applied products used on or within assemblies are classified according to their specific product category. Storefront systems are not the intended wet-applied adhesives and sealants example in this requirement. The purpose is to reduce occupants ' exposure to chemical contaminants from interior materials and construction products. Therefore, adhesives or sealants used with an air or vapor barrier membrane are subject to the applicable VOC emissions evaluation. U.S. Green Building Council

According to the LEED AP Building Design + Construction (LEED AP BD+C) V4 resources, the Water Efficiency Prerequisite for Indoor Water Use Reduction requires the project to reduce aggregate water consumption by 20% from the baseline. Therefore, the project can meet this prerequisite with a 24% water reduction. However, to earn points under the Water Efficiency Credit for Indoor Water Use Reduction, the project needs to achieve a higher level of water reduction, ranging from 25% to 50%. The credit awards points based on the percentage of water reduction achieved, as shown in Table 1. Thus, the project may pursue this credit if it can further reduce its water consumption by installing more efficient fixtures and fittings, appliances, equipment and processes.

As per the LEED AP Building Design + Construction (LEED AP BD+C) V4 resources, the Water Efficiency Prerequisite and Credit for Indoor Water Use Reduction are based on an “efficiency first” approach to water conservation. The prerequisite sets a minimum standard of 20% water reduction from the baseline, while the credit rewards higher levels of performance up to 50% water reduction. The baseline water consumption of fixtures and fittings is based on the volumes and flow rates shown in Table 2. The credit also requires that all newly installed toilets, urinals, private lavatory faucets and showerheads that are eligible for labeling must be WaterSense labeled (or a local equivalent for projects outside the U.S.). For more detailed information, you can refer to the web-based reference guide in the credit library at USGBC’s official website.

The total water use is calculated by adding the consumption associated with every listed fixture and appliance. The calculation is 600 gal. for toilets, plus 300 gal. for urinals, plus 100 gal. for the kitchen faucet, plus 200 gal. for the commercial dishwasher, plus 200 gal. for lavatory faucets. This produces 1,400 gal. The corresponding metric total is approximately 5,299.6 litres. Although LEED water-efficiency documentation normally distinguishes fixture water, appliance water, process water, baseline use, and proposed use, the question asks only for the combined consumption of the listed components. Therefore, no percentage reduction or baseline comparison is required, and Option A is the correct mathematical total.

Tidal-based electrical production is eligible for the Energy and Atmosphere Credit, Renewable Energy Production. This credit rewards projects that use renewable energy systems to offset building energy cost.According to theLEED V5BD+C Reference Guide, renewable energy systems are defined as “those that use resources that are naturally replenished within a 100-year or shortercycle and that are greenhouse gas neutral on an annual basis”1. Tidal-based electrical production meets this definition, as it uses the kinetic energy of the tides to generate electricity without emitting greenhouse gases. The other options are not eligible for this credit, as ground-source heat pumps are not considered renewable energy systems, municipal solid waste combustion is not greenhouse gas neutral, and passive solar and daylighting strategies do not offset building energy cost.

This option requires the project team to calculate the weighted daily average of the number of trips per day for each qualifying route, using the formula provided in theLEED V5: Building Design + Construction Guide. This option ensures that the transit service frequency is accurately represented and meets the minimum thresholds for weekday and weekend trips, as shown in Table 1 and Table 2 of the guide.

A compliant water meter is a device that measures and records the total potable water use of the building and associated grounds. According to theLEED V5Reference Guide for Building Design and Construction, a compliant water meter must meet the following requirements1:

•It must be permanently installed and measure the total water use of the building and grounds.

•It must have a remote communication capability or be readable from a location that is accessible to building management.

•It must have a data storage capability of at least 18 months, or be connected to a system that can store data for at least 18 months.

•It must have a resolution of 0.5 gallons (2 liters) or less, or the smallest unit of measure that is appropriate for the expected water use of the building.

Access to medical services is a direct determinant of community and occupant health and should therefore be evaluated in a human-impact assessment. The assessment examines how the project may affect people who use the building or live in the surrounding community, including vulnerable populations and groups that may experience unequal access to essential resources. Evaluating healthcare access can reveal whether occupants have reasonable proximity to clinics, hospitals, emergency services, preventive care, and other health-supporting facilities. Transportation access may also influence human outcomes, but the option is framed broadly and does not specifically measure health-service availability. Proximity to manufacturing plants is relevant only when linked to documented exposure, pollution, employment, or environmental-justice concerns. LEED v5 explicitly prioritizes health, resilience, equity, and community quality of life.

These design elements are examples of low-impact development (LID) and green infrastructure (GI) practices that can reduce runoff volume and improve water quality by replicating the natural hydrology and water balance of the site1. Cisterns can collect and store rainwater for reuse or infiltration, porous pavement can allow water to seep into the ground, swales can convey and filter stormwater runoff, and vegetated roofs can reduce runoff and evapotranspiration2.

Tidal energy conversion is a qualifying renewable-energy generation technology, making Option A correct. USGBC renewable-energy guidance identifies wave and tidal energy among eligible renewable systems. By contrast, combustion of municipal solid waste is specifically excluded as an eligible renewable-energy source. Ground-source heat pumps improve energy efficiency by transferring heat to or from the earth, but LEED distinguishes this from qualifying geothermal renewable-energy generation; vapor-compression ground-source heat-pump systems are treated as efficiency strategies rather than renewable-energy production. Passive solar design and daylighting similarly reduce building energy demand but do not generate qualifying renewable energy for EAc4. LEED v5 EAc4 rewards qualifying renewable-energy supply or procurement, and tidal generation fits the renewable-resource principle while the other three options do not meet the credit ' s renewable-generation definition.

Among the provided choices, increasing glare-control devices is the only strategy that supports effective use of daylight while maintaining visual comfort. LEED v5 addresses daylight under EQc2: Occupant Experience, Option 5: Lighting Environment. Daylight simulation evaluates spatial daylight autonomy and annual sunlight exposure, and where excessive annual sunlight exposure occurs, the design must specifically demonstrate how glare is addressed. Glare-control devices such as shades or other solar-control measures therefore allow useful daylight while limiting excessive brightness and visual discomfort. Increasing building depth and raising interior partitions generally obstruct daylight penetration. Decreasing exterior light shelves can also reduce daylight distribution into deeper portions of occupied spaces. Therefore, Option D is the best strategy available among the listed choices.

The best practice for using alternative water sources is to target the uses that require the least treatment first, such as irrigation, toilet flushing, and cooling tower makeup. This reduces the energy and cost associated with treating water to higher standards than necessary. Matching uses by location is not a requirement, nor is treating all alternative water sources to potable water standards.A project may use more than one alternative water source as long as they meet the applicable codes and standards.References: WE Credit Indoor Water Use Reduction, WE Credit Outdoor Water Use Reduction, WE Credit Cooling Tower Water Use1
