Free LEED Green Associate Practice Test (LEED v5)

Answer: B. Green Business Certification Inc. (GBCI)

GBCI provides third-party verification for both project certification and professional credentials. Keep "who writes LEED" (USGBC) separate from "who verifies it" (GBCI).

• Why not A: USGBC develops the LEED rating system. Review and certification sit with GBCI.
• Why not C: Prometric delivers GBCI's credential exams. It doesn't review buildings.
• Why not D: Building departments enforce codes. LEED is a voluntary program reviewed outside the permit process.

Answer: D. LEED Green Associate

Once you pass, you can use the title "LEED Green Associate." The handbook specifically says "LEED GA" is not an approved abbreviation.

• Why not A: The handbook says "LEED GA" is not an approved abbreviation and shouldn't be used.
• Why not B: Buildings are certified; people earn credentials. This isn't a GBCI title.
• Why not C: LEED AP is a separate, advanced credential with its own specialty exams.

Answer: A. A consensus committee approves it through a ballot process, and USGBC members ratify it by vote

GBCI's handbook describes the sequence: a new LEED version is approved by the relevant consensus committee through a ballot process and ratified by a vote of USGBC's membership. That consensus, member-driven process is a core idea in the LEED Process domain.

• Why not B: Exam development follows a new rating system; it doesn't create one.
• Why not C: LEED is a voluntary program, not a federal rule.
• Why not D: Prometric only delivers exams.

Answer: C. Every applicable prerequisite in the chosen rating system must be met, and prerequisites earn no points

Applicable prerequisites are mandatory and carry no points; points come from credits. That's why the v5 BD+C scorecard lists prerequisites as "Required" rather than giving them point values.

• Why not A: Points come from credits. Prerequisites are pass/fail requirements.
• Why not B: Extra points never replace a missed prerequisite.
• Why not D: Prerequisites apply at every certification level.

Answer: D. Must be in a permanent location on existing land

LEED evaluates projects in the context of their location. This unanchored, trailer-mounted classroom fails the permanent-location requirement. A modular building anchored to a permanent foundation can qualify even if it could later be dismantled; certification does not transfer to a new location.

• Why not A: Nothing in the scenario suggests the boundary was drawn to gain an advantage.
• Why not B: At 1,800 square feet, the classroom is above the 1,000-square-foot BD+C minimum.
• Why not C: Project Priorities points are optional credits, not a Minimum Program Requirement.

Answer: C. The boundary unreasonably excludes part of the site to gain a credit advantage

The v5 "reasonable boundaries" requirement says the boundary may not unreasonably exclude portions of the building, space or site to give the project an advantage in meeting credit requirements. Leaving out a lot the project actually uses is the textbook example.

• Why not A: The boundary is the team's choice, but it can't be drawn unreasonably to make compliance easier.
• Why not B: Excluding a parking lot doesn't make the building relocatable.
• Why not D: Floor area is about the building, not the parking lot.

Review topic: Minimum Program Requirements. Source: USGBC, Minimum Program Requirements

Answer: A. 250 sq ft

The size requirement is 1,000 sq ft of gross floor area for BD+C and O+M, and 250 sq ft for ID+C.

• Why not B: Not a LEED v5 threshold.
• Why not C: That's the minimum for BD+C and O+M projects, not ID+C.
• Why not D: Not a LEED v5 minimum program threshold.

Answer: B. Silver

The point bands are Certified 40-49, Silver 50-59, Gold 60-79 and Platinum 80 and up, out of 110 possible points. Fifty-two points falls in the Silver band.

• Why not A: Certified is 40-49 points.
• Why not C: Gold starts at 60 points.
• Why not D: Platinum starts at 80 points, and v5 adds credit-specific Platinum requirements.

Review topic: Certification levels. Source: USGBC, LEED overview; USGBC, LEED v5 BD+C — Rating-system scorecard and impact areas

Answer: C. In v5, reaching 80 points doesn't by itself secure Platinum; some credits carry Platinum requirements

The v5 BD+C: New Construction Renewable Energy credit states a Platinum requirement: 100% of site energy use from any combination of Tier 1, Tier 2 and Tier 3 renewable energy. So a high point total alone doesn't guarantee the top level. Treat this as a v5 change to watch for in older study material.

• Why not A: Credit-level Platinum requirements also apply in v5, and all applicable prerequisites must be met at every certification level.
• Why not B: Points don't substitute for a stated Platinum requirement.
• Why not D: The Renewable Energy credit in v5 BD+C itself contains a Platinum requirement.

Answer: D. Decarbonization; quality of life; ecological conservation and restoration

LEED v5 groups its requirements under decarbonization, quality of life, and ecological conservation and restoration. The current exam specifications list "impact areas" under the LEED Process domain.

• Why not A: These are resource topics that map to credit categories, not the v5 impact areas.
• Why not B: These describe credit categories, not impact areas.
• Why not C: That's the triple bottom line, a general sustainability idea rather than LEED v5's framework.

Review topic: v5 impact areas. Source: USGBC, LEED v5 BD+C — Rating-system scorecard and impact areas; USGBC, LEED v5; GBCI, LEED Green Associate Candidate Handbook (current LEED v5)

Answer: B. The Project Priorities credit category

In v5 BD+C, the Project Priorities credit (up to 9 points) covers regional priority, project-type, exemplary performance, pilot credits and innovative strategies. Those separate category names belong to v4/v4.1, not to the v5 BD+C scorecard.

• Why not A: Those were the v4/v4.1 category names. In v5 they're folded into Project Priorities.
• Why not C: That category holds the assessments and integrative design, not regional or pilot credits.
• Why not D: v5 still recognizes them, under Project Priorities.

Review topic: Project Priorities. Source: USGBC, LEED v5 BD+C — Project Priorities; USGBC, LEED v5 BD+C — Rating-system scorecard; USGBC, LEED v4.1 BD+C guide (historical)

Answer: A. No. At least one principal participant must be a LEED AP with a specialty appropriate for the project

The v5 LEED AP credit is worth 1 point and requires at least one principal participant who is a LEED AP with a specialty appropriate for the project. A Green Associate credential doesn't satisfy it.

• Why not B: The credit asks specifically for a LEED AP with an appropriate specialty.
• Why not C: The number of Green Associates doesn't matter for this credit.
• Why not D: v5 keeps it as a 1-point credit under Project Priorities.

Answer: D. ID+C (Interior Design and Construction)

Interior fit-outs that don't touch the building's structure, envelope or site belong in ID+C. Matching the project scope to the right family is a core LEED Process skill and is covered by USGBC's rating system selection guidance.

• Why not A: New Construction covers whole new buildings and major renovations, not a single tenant fit-out.
• Why not B: O+M certifies how an existing building performs in operation.
• Why not C: Core and Shell is for the base building when tenant spaces are left for others to finish.

Review topic: Rating system selection. Source: USGBC, LEED Rating System Selection Guidance; USGBC, LEED v5 BD+C — Rating-system scorecard

Answer: B. O+M (Operations and Maintenance)

O+M certifies existing buildings based on how they operate. The v5 O+M rating system includes performance-based credits such as water efficiency performance and greenhouse gas emissions reduction performance.

• Why not A: No new construction or major renovation is happening.
• Why not C: ID+C is for interior fit-outs, not whole-building operations.
• Why not D: Core and Shell is a design and construction system for new base buildings or qualifying major renovations, not day-to-day operations.

Answer: A. A CIR answers one project's question; only a published LEED Interpretation can apply to other projects, within its stated applicability

USGBC's certification guidance separates project-specific CIRs from published LEED Interpretations, which can establish precedent within their stated applicability. Either way, the team still has to document compliance.

• Why not B: CIRs are project-specific rulings.
• Why not C: That's backwards. Published Interpretations are the ones that can set precedent.
• Why not D: Published LEED Interpretations and addenda can apply; the original text isn't the only authority.

Answer: C. Climate Resilience Assessment, Human Impact Assessment and Carbon Assessment

v5 BD+C:NC puts three required assessments at the front of the rating system: climate resilience, human impact and carbon. Each is meant to inform design decisions early rather than be documented at the end.

• Why not A: These are Energy and Atmosphere prerequisites.
• Why not B: These are Indoor Environmental Quality prerequisites.
• Why not D: In v4.1 Integrative Process was a credit and Site Assessment was a Sustainable Sites credit. Neither is a v5 IP prerequisite.

Answer: B. Operational energy, refrigerants and embodied carbon

The projection draws on data from the Operational Carbon Projection and Decarbonization Plan, Fundamental Refrigerant Management and the embodied carbon prerequisite. Transportation demand data can be added but is optional.

• Why not A: Operational energy is only one of the three inputs.
• Why not C: Embodied carbon is one input, alongside operations and refrigerants.
• Why not D: Transportation data is optional, not one of the three core inputs.

Review topic: Carbon Assessment. Source: USGBC, LEED v5 BD+C — Carbon Assessment

Answer: C. Compare the options together, across disciplines, before fixing the design

Integrative design means looking at how systems interact while the design can still change. Early, cross-discipline analysis makes tradeoffs like more glass versus more cooling easier to resolve before the choices are locked in.

• Why not A: That postpones coordination until changes are expensive.
• Why not B: That locks in one choice before its effects on the others are known.
• Why not D: Documentation records decisions; it doesn't help make them.

Answer: D. The combined effect on lighting and cooling, evaluated under the same project assumptions

Systems thinking asks how a change in one system affects others. Here the team needs to model lighting and cooling together, with consistent assumptions, before calling the daylighting option an improvement.

• Why not A: Added solar heat gain can outweigh lighting savings.
• Why not B: Cost matters, but it doesn't answer the energy question.
• Why not C: There are no occupants yet, and a survey can't predict the energy tradeoff.

Answer: A. They bring practical knowledge of how systems will actually be operated and maintained

The current exam specifications list the facility manager among integrative team members. Operations staff can flag maintenance access, controls and staffing limits that designers might miss.

• Why not B: Exam registration is individual and unrelated to project teams.
• Why not C: Commissioning is a separate quality-assurance role.
• Why not D: Certification thresholds are set in the rating system, not by project staff.

Answer: B. System B, by $4,000

System A: $12,000 + ($3,000 × 10) = $42,000. System B: $18,000 + ($2,000 × 10) = $38,000. B is $4,000 cheaper over the period even though it costs more up front. This is a simplified life-cycle cost comparison, which is a financial tool; life-cycle assessment (LCA) measures environmental impacts instead.

• Why not A: $6,000 is the difference in first cost only.
• Why not C: This reverses the result. A totals $42,000 and B totals $38,000.
• Why not D: Neither total is $40,000.

Answer: A. Placing the development footprint on a lot that held a since-demolished warehouse

Option 1 of the v5 credit is met by locating the development footprint on previously developed land. Reusing developed land reduces pressure to build on undeveloped land.

• Why not B: That's undeveloped land, and it's near a sensitive feature.
• Why not C: Cheap land isn't the test. The parcel is undeveloped.
• Why not D: This parcel is previously undeveloped, so it does not meet the stated option; floodplains also appear in the credit's sensitive-land criteria.

Review topic: Sensitive land protection. Source: USGBC, LEED v5 BD+C — Sensitive Land Protection

Answer: C. An area with a 1% or greater chance of flooding in any given year

The credit describes the 100-year floodplain as land subject to a 1% or greater chance of flooding in any given year. It's a probability, not a schedule.

• Why not A: The 1% chance applies every year. Back-to-back floods are possible.
• Why not B: The definition is about annual probability, not flood history.
• Why not D: That confuses the flood definition with a distance buffer.

Review topic: Floodplains. Source: USGBC, LEED v5 BD+C — Sensitive Land Protection

Answer: D. A downtown infill lot within walking distance of shops, services and frequent bus service

Compact, connected locations with nearby daily uses and real transit give people alternatives to driving. That's a core smart growth principle, and v5 groups these location factors in its Compact and Connected Development credit.

• Why not A: Ample free parking encourages driving.
• Why not B: Highway access makes driving the default.
• Why not C: Distance from daily destinations increases car dependence.

Review topic: Compact development. Source: EPA, About Smart Growth; USGBC, LEED v5 BD+C — Rating-system scorecard; USGBC, LEED v5 BD+C — Compact and Connected Development

Answer: C. Compact and Connected Development

v5 consolidates several older location credits into Compact and Connected Development. The other three names come from v4.1. Check the version named in the stem rather than treating historical distractors as evidence that a question is outdated.

• Why not A: That's a v4.1 credit name.

Answer: B. A transportation demand management program with transit passes, carpool matching and secure bike parking

Transportation demand management works on travel behavior itself: making transit, carpooling and cycling practical. The question's goal is fewer drive-alone miles, so the strategy that changes how people commute is the best fit.

• Why not A: This can cut emissions per mile, but it doesn't reduce the miles driven.
• Why not C: More free parking makes driving alone easier.
• Why not D: That saves energy but doesn't change how people travel.

Answer: D. Map distance alone doesn't establish usable access; the actual route and users' needs have to be considered

Good location credits depend on access people can actually use. A short distance on paper doesn't help if the walking route is unsafe, which is why site assessments look at the real path and the people using it.

• Why not A: Straight-line distance ignores whether people can safely get there.
• Why not B: That ignores occupants who don't or can't drive.
• Why not C: Transit access is part of v5's location credits.

Answer: A. A property whose expansion, redevelopment or reuse may be complicated by real or potential contamination

A brownfield is a property whose expansion, redevelopment or reuse may be complicated by the presence or potential presence of contamination. Assessing and, where needed, cleaning up these properties supports their reuse.

• Why not B: Dry grass or a property's color does not establish actual or potential contamination.
• Why not C: Former farmland isn't automatically a brownfield.
• Why not D: Assessment determines what contamination and cleanup or management needs are present; reuse is not a blanket exemption from further checks.

Review topic: Brownfields. Source: EPA, Environmental Contamination at Brownfield Sites; EPA, About Smart Growth

Answer: C. The vacant lot, because it uses existing infrastructure and avoids disturbing habitat, subject to its own site assessment

LEED rewards development on land that's already disturbed and served by infrastructure. The vacant lot still needs its own assessment, but it avoids clearing habitat and extending services into undeveloped land.

• Why not A: Efficient new utilities don't avoid the habitat clearing or the need to extend services.
• Why not B: Location and Transportation is an entire LEED domain.
• Why not D: Off-site planting doesn't avoid the habitat loss on this site.

Review topic: Site selection. Source: EPA, About Smart Growth; USGBC, LEED v5 BD+C — Sensitive Land Protection

Answer: B. Providing less parking than is typical, charging for it, and supporting transit and carpool options

The current exam specifications list reduction in parking footprint under transportation demand management. Less parking, priced appropriately and paired with alternatives, can reduce driving demand and land devoted to parking.

• Why not A: That increases the footprint and encourages driving.
• Why not C: That adds paving and removes vegetated area.
• Why not D: A larger garage adds parking capacity rather than reducing demand for parking.

Answer: A. Minimize Site Disturbance

v5 replaced Construction Activity Pollution Prevention with Minimize Site Disturbance. It still requires an erosion and sedimentation control plan, and it adds site assessment work such as protecting healthy plant communities.

• Why not B: That was the v4.1 prerequisite name.
• Why not C: That's a v4.1 Schools prerequisite, not the v5 NC prerequisite.
• Why not D: Rainwater Management is a v5 credit, not a prerequisite.

Answer: D. By shading surfaces and cooling the air through evapotranspiration

Trees and vegetation cool their surroundings in two ways: shade keeps surfaces from heating up, and evapotranspiration releases water vapor that cools the air. That's why v5's heat island credit counts shade over paving.

• Why not A: That reverses the mechanism.
• Why not B: Trees don't generate electricity.
• Why not C: Benefits vary with climate, species and canopy size.

Answer: C. A properly designed vegetated rain garden that collects and soaks in runoff

Rain gardens hold runoff and let it soak into the ground, reducing the volume and pollutants reaching storm drains. They work when soils and siting are suitable, which the scenario provides.

• Why not A: That increases runoff.
• Why not B: That moves the problem without managing it.
• Why not D: Infiltration depends on soils, siting and sizing.

Answer: B. Limiting uplight, light trespass and glare from exterior luminaires

The v5 credit sets limits on uplight and on light trespass (backlight and glare ratings) for exterior luminaires, plus nighttime luminance limits for internally lit signs. Its intent is to protect night sky access and reduce effects on wildlife and people.

• Why not A: More output without control makes spill worse.
• Why not C: The credit addresses exterior lighting.
• Why not D: Compliance is based on uplight, backlight and glare ratings, not color.

Review topic: Light pollution. Source: USGBC, LEED v5 BD+C — Light Pollution Reduction

Answer: A. An open-grid pavement system that's at least 50% unbound

Nonroof measures in v5 include shade over paving, paving with an initial solar reflectance (SR) of at least 0.33, and open-grid pavement that's at least 50% unbound. The open grid lets vegetation or permeable material break up the heat-absorbing surface.

• Why not B: Dark, low-reflectance asphalt absorbs heat.
• Why not C: The credit needs a measured solar reflectance, not a color choice.
• Why not D: Dark surfacing absorbs heat.

Answer: D. Use a tree-equity evaluation of the location to increase on-site tree canopy

For U.S. projects, the team checks the American Forests Tree Equity Score for the location and, in high-priority areas, uses it to increase on-site canopy. It ties heat-island work to neighborhoods with less tree cover.

• Why not A: The option focuses on canopy at the project site informed by the local evaluation.
• Why not B: That reduces canopy.
• Why not C: Indoor plants aren't tree canopy.

Answer: B. Protect it with an exclusion zone marked by physical barriers during construction

The prerequisite asks teams to identify healthy plant communities, minimize damage to them, and establish exclusion zones with physical barriers during construction. Its intent is to preserve native vegetation, healthy soils and habitat.

• Why not A: The prerequisite requires minimizing damage, not documenting it.
• Why not C: A rendering isn't an assessment of existing conditions.
• Why not D: Off-site restoration doesn't meet the requirement to protect identified healthy plant communities.

Review topic: Protecting habitat during construction. Source: USGBC, LEED v5 BD+C — Minimize Site Disturbance

Answer: A. Use them to choose site strategies that address those specific hazards

v5's Climate Resilience Assessment covers current and projected hazards, requires at least two priority hazards, and asks the team to use the findings in planning, design and operations. Site design is where heat and flood strategies usually land.

• Why not B: The requirement asks teams to use the assessment to inform planning and design.
• Why not C: Strategies should respond to the identified hazards.
• Why not D: The assessment covers current and projected future hazards.

Review topic: Site resilience. Source: USGBC, LEED v5 BD+C — Climate Resilience Assessment

Answer: C. Install fixtures at or below listed maximum flush and flow rates, or show a 20% aggregate reduction from a baseline

The prerequisite has a prescriptive path (no fixture over the listed maximum rates) and a performance path (aggregate use 20% below the baseline table). It also sets separate appliance, process water and outdoor requirements.

• Why not A: WaterSense is recommended, but neither of these is a compliance path.
• Why not B: Outdoor and indoor requirements are separate; one doesn't replace the other.
• Why not D: Neither is a compliance path.

Review topic: Minimum water efficiency. Source: USGBC, LEED v5 BD+C — Minimum Water Efficiency

Answer: B. 20%

Percent reduction = (baseline − proposed) ÷ baseline = (1.6 − 1.28) ÷ 1.6 = 0.32 ÷ 1.6 = 20%. Always divide by the baseline. In v5, 1.6 gpf is the baseline and 1.28 gpf is the prescriptive maximum.

• Why not A: That reads the new flush volume as a percentage.
• Why not C: That divides the savings by the new flow (0.32 ÷ 1.28) instead of by the baseline.
• Why not D: 0.32 is the gallons saved per flush, not a percentage.

Review topic: Percent reduction. Source: USGBC, LEED v5 BD+C — Minimum Water Efficiency

Answer: D. Up to a two-year establishment period

The no-irrigation option asks the team to show the landscape doesn't need a permanent irrigation system beyond a maximum two-year establishment period. The alternative option is efficient irrigation that cuts the irrigation requirement by at least 30% from a calculated baseline.

• Why not A: Temporary watering during establishment is allowed.
• Why not B: The establishment period is a maximum of two years.
• Why not C: A permanent system, timer or not, isn't a no-irrigation landscape.

Review topic: Outdoor water use. Source: USGBC, LEED v5 BD+C — Minimum Water Efficiency

Answer: C. Choose low-water, noninvasive plants suited to that microclimate, and water appropriately while they establish

Matching plants to site conditions and grouping them by water needs cuts irrigation demand. New plantings still need care while they establish, which is why v5 allows a temporary establishment period.

• Why not A: Native plants vary; suitability depends on the specific conditions.
• Why not B: New plantings usually need water while they establish.
• Why not D: Appearance alone ignores water needs.

Answer: D. A soil moisture-based controller

Smart irrigation controllers come in two main types: weather-based controllers use local weather data, and soil moisture-based controllers use sensors in the root zone. The second type is the one that responds to measured soil moisture.

• Why not A: Clock timers run on a schedule regardless of conditions.
• Why not B: A meter measures use; it doesn't control irrigation.
• Why not C: Weather-based controllers use weather data, not soil moisture readings.

Review topic: Irrigation controls. Source: EPA WaterSense, Labeled Irrigation Controllers

Answer: A. Use meter and submeter data to trace where the flow occurs, then inspect the likely equipment

Metering is how you find and verify problems. Unexpected overnight use is a signal to investigate, starting with submeters and equipment, rather than proof of a specific cause.

• Why not B: That spends money before the source is found.
• Why not C: Overnight flow can also come from equipment schedules or settings.
• Why not D: A bill shows a total, not where water is going.

Answer: B. It replaces potable (drinking-quality) water for that use

Onsite non-potable reuse uses water treated to fit its purpose, such as toilet flushing, so drinking-quality water isn't used where it isn't needed. The system has to meet local rules, which the scenario states it does.

• Why not A: Treatment for flushing doesn't make water potable.
• Why not C: Efficient fixtures still reduce total demand.
• Why not D: Onsite reuse depends on local regulations.

Review topic: Water reuse. Source: EPA, Onsite Non-Potable Water Reuse Resources

Answer: C. Once-through cooling with potable water

Once-through cooling runs potable water through equipment a single time and then down the drain. v5 BD+C prohibits it for any equipment or appliance that rejects heat.

• Why not A: v5 calls for air-cooled or closed-loop cooling for ice machines.
• Why not B: Conductivity controllers are required, not prohibited.
• Why not D: Closed-loop systems avoid dumping water after one pass.

Review topic: Process water. Source: USGBC, LEED v5 BD+C — Minimum Water Efficiency

Answer: D. Makeup water meters, conductivity controllers and overflow alarms, and efficient drift eliminators

v5 requires makeup water meters, conductivity controllers and overflow alarms, and efficient drift eliminators. Together they let operators track water, control how often water is dumped, and limit spray losses.

• Why not A: These aren't the listed requirements.
• Why not B: Not a water efficiency requirement.
• Why not C: Once-through potable cooling is prohibited.

Review topic: Cooling towers. Source: USGBC, LEED v5 BD+C — Minimum Water Efficiency

Answer: A. Total daily use rose 20%, and use per person fell 20%

Total: (3,600 − 3,000) ÷ 3,000 = 20% increase. Per person: 3,000 ÷ 100 = 30 gallons, and 3,600 ÷ 150 = 24 gallons; (30 − 24) ÷ 30 = 20% decrease. Neither number alone explains why use changed.

• Why not B: Per-person use actually fell; total use alone doesn't show efficiency.
• Why not C: These divide by the wrong baselines (600 ÷ 3,600 and 6 ÷ 24).
• Why not D: Per-person use went from 30 to 24 gallons, a decrease.

Answer: B. Operational Carbon Projection and Decarbonization Plan

v5 BD+C opens its Energy and Atmosphere category with the Operational Carbon Projection and Decarbonization Plan. It's new in v5 and a good marker that study material is current.

• Why not A: That prerequisite sets an efficiency floor; it isn't the carbon projection and plan.
• Why not C: Commissioning verifies systems against the owner's requirements.
• Why not D: That's an optional credit, not a prerequisite.

Answer: A. Commissioning

Commissioning is a quality-assurance process. In v5, the commissioning provider helps develop the owner's project requirements, reviews the design and construction against them, and plans ongoing commissioning.

• Why not B: Benchmarking compares energy performance; it doesn't verify system installation.
• Why not C: Certification review checks LEED documentation.
• Why not D: Value engineering looks for cost savings.

Review topic: Commissioning. Source: USGBC, LEED v5 BD+C — Fundamental Commissioning; DOE FEMP, Commissioning in Federal Buildings

Answer: D. The OPR states what the owner needs from the building; the BOD explains how the design team's design meets those needs

The OPR captures the owner's goals and requirements, and the BOD documents how the design meets them. The v5 commissioning prerequisite has the provider help develop the OPR and review the BOD for compliance with it.

• Why not A: The OPR comes from the owner, and the BOD from the design team.
• Why not B: They're separate documents with different authors and purposes.
• Why not C: The BOD is a design document; the commissioning provider reviews it during design.

Review topic: OPR and BOD. Source: USGBC, LEED v5 BD+C — Fundamental Commissioning

Answer: C. By the end of the design development phase

v5 requires the owner to designate a commissioning provider by the end of design development. The provider should help develop the OPR in predesign or as early as possible, so earlier is better.

• Why not A: Commissioning starts long before construction ends.
• Why not B: That's far too late to influence design.
• Why not D: Commissioning is required for all projects.

Answer: A. Hydrochlorofluorocarbons (HCFCs)

The v5 prerequisite prohibits HCFCs in new equipment. It also requires a refrigerant inventory, an evaluation of alternatives for refrigerants above a GWP of 700, and leak checks before substantial completion.

• Why not B: Projects can use refrigerants if they meet the inventory, evaluation and leak-check requirements.
• Why not C: A GWP below 700 is not itself a prohibited class. The HCFC prohibition still applies regardless of GWP.
• Why not D: Nothing in the prerequisite prohibits them.

Answer: C. Nothing by itself; some refrigerants that don't deplete ozone, such as many HFCs, have high global warming potential

EPA notes that hydrofluorocarbons (HFCs) don't deplete the stratospheric ozone layer, yet they're potent greenhouse gases with impacts hundreds to thousands of times greater than the same amount of CO2. Check both measures, not one.

• Why not A: Ozone depletion and global warming potential are separate measures.
• Why not B: Many non-ozone-depleting refrigerants are potent greenhouse gases.
• Why not D: CO2 has a GWP of 1 by definition; HFCs are often far higher.

Answer: A. 23

Each REC represents the attributes of 1 MWh of renewable generation, so 35 − 12 = 23 more RECs. A REC is an accounting instrument, not stored electricity.

• Why not B: That ignores the 12 RECs already held.
• Why not C: That adds instead of subtracting.
• Why not D: That treats each REC as 1 kilowatt-hour instead of 1 MWh.

Review topic: Renewable energy certificates. Source: EPA, Renewable Energy Certificates (RECs)

Answer: B. They must be retired on behalf of the LEED project

v5 requires that all environmental attributes, including RECs, be retired on behalf of the LEED project. EPA explains that RECs are how renewable electricity use claims are substantiated, so each one can back only one claim.

• Why not A: Reselling would let someone else claim the same renewable attributes.
• Why not C: RECs aren't physical energy.
• Why not D: That would be double counting.

Review topic: RECs and claims. Source: USGBC, LEED v5 BD+C — Renewable Energy; EPA, Renewable Energy Certificates (RECs)

Answer: D. A photovoltaic (solar) system on the project site

Tier 1 includes on-site generation, campus generation and qualifying social impact projects. The on-site photovoltaic system fits that tier. New off-site generation can qualify for Tier 2 when its conditions are met; other eligible off-site supply can qualify for Tier 3. Certification or a new contract alone does not determine a tier.

• Why not A: Green-e certification alone does not establish the location or project conditions for Tier 1.
• Why not B: A new off-site wind farm outside the excluded Tier 1 paths may qualify for Tier 2, subject to the credit’s conditions.
• Why not C: Offsets represent avoided emissions, not renewable electricity, so they aren't a renewable tier.

Answer: B. Direct (Scope 1) emissions from burning gas go away, but emissions tied to the purchased electricity (Scope 2) still count

EPA defines Scope 1 as direct emissions from sources an organization owns or controls, such as boilers, and Scope 2 as indirect emissions from purchased electricity, steam, heat or cooling. Electrification shifts emissions from one scope to the other; it doesn't erase them automatically.

• Why not A: Electrification alone does not establish zero operational emissions for the whole building.
• Why not C: Purchased electricity is Scope 2.
• Why not D: Manufacturing emissions are embodied carbon, not purchased energy.

Answer: C. Compare them using normalized benchmarking that accounts for size, use and weather

Benchmarking compares buildings fairly by normalizing for factors like floor area, operating hours and weather. Without that, raw totals can confuse differences in size and climate with differences in efficiency.

• Why not A: Raw totals ignore size, occupancy and climate.
• Why not B: Price doesn't measure energy performance.
• Why not D: One hour can't represent annual performance.

Review topic: Benchmarking. Source: GSA, Building energy security and efficiency

Answer: D. Schedule that load outside the 4-8 p.m. peak

Demand flexibility shifts suitable loads away from grid peaks. It reduces strain on the grid at critical hours even if total energy use stays about the same. LEED v5 BD+C includes a Grid Interactive credit in Energy and Atmosphere.

• Why not A: That adds to peak demand.
• Why not B: Shifting load can cut peak demand without changing total energy.
• Why not C: The scenario only works because the load is flexible.

Review topic: Load shifting. Source: GSA, Building energy security and efficiency; USGBC, LEED v5 BD+C — Rating-system scorecard

Answer: C. Not yet; it has to hold other assumptions constant before crediting the walls with the difference

To isolate one design choice in an energy model, keep every other assumption the same. Otherwise the result mixes the wall's effect with the schedule's effect.

• Why not A: The schedule change could explain some or all of it.
• Why not B: Changing variables at once makes it impossible to isolate one cause.
• Why not D: A label doesn't show how the assembly performs in this building.

Review topic: Energy modeling. Source: GSA, Building energy security and efficiency

Answer: A. 4 hours

Run time = energy ÷ power = 120 kWh ÷ 30 kW = 4 hours. This is an idealized exercise; real systems have losses, reserve limits and output limits.

• Why not B: That divides kW by kWh, the wrong way around.
• Why not C: That subtracts the load from the stored energy.
• Why not D: That multiplies the two numbers.

Review topic: Energy storage. Source: GSA, Building energy security and efficiency

Answer: B. Re-evaluate equipment sizing against the reduced load instead of keeping the original sizes

Reducing loads first can allow smaller equipment, which saves first cost and energy. LEED v5 BD+C also has a credit named Reduce Peak Thermal Loads in Energy and Atmosphere.

• Why not A: Oversized equipment can cost more and run less efficiently.
• Why not C: Floor area ignores the envelope improvement.
• Why not D: Models estimate performance; they don't guarantee it.

Answer: D. Cradle-to-gate (stages A1-A3)

The prerequisite asks for cradle-to-gate (A1-A3) global warming potential for each material, calculated as GWP per unit times quantity, or reported from LCA software.

• Why not A: Operational energy is handled in the Energy and Atmosphere category.
• Why not B: The prerequisite focuses on cradle-to-gate, not disposal.
• Why not C: Commuting isn't part of material embodied carbon.

Review topic: Embodied carbon scope. Source: USGBC, LEED v5 BD+C — Quantify and Assess Embodied Carbon

Answer: B. Concrete in the foundations and slabs

The minimum material list covers structure, enclosure and hardscape, including asphalt, concrete, masonry, structural steel, insulation, aluminum extrusions, structural wood, cladding and glass.

• Why not A: Furniture isn't in the prerequisite's structure, enclosure and hardscape scope.
• Why not C: Interior finishes aren't in the minimum scope.
• Why not D: Appliances aren't structure, enclosure or hardscape.

Review topic: Embodied carbon scope. Source: USGBC, LEED v5 BD+C — Quantify and Assess Embodied Carbon

Answer: A. Identify the top three sources and describe how project-specific strategies were considered to reduce them

Beyond the number, the prerequisite asks teams to find their biggest "hot spots" and show they considered ways to cut them. That turns measurement into design decisions.

• Why not B: Offsets aren't part of this prerequisite.
• Why not C: Not required by the prerequisite.
• Why not D: No single material swap is required.

Answer: D. Planning for Zero Waste Operations

v5 BD+C:NC has two MR prerequisites: Planning for Zero Waste Operations and Quantify and Assess Embodied Carbon. The other three names are from v4.1.

• Why not A: That was the v4.1 prerequisite name.
• Why not B: That was a v4.1 prerequisite; in v5, C&D waste diversion is a credit.
• Why not C: That was a v4.1 credit.

Review topic: v5 MR prerequisites. Source: USGBC, LEED v5 BD+C — Rating-system scorecard; USGBC, LEED v4.1 BD+C guide (historical)

Answer: C. Materials and Resources

v5 BD+C lists Low-Emitting Materials as an MR credit. That project-credit category is different from the exam's topic map: the current Green Associate handbook still lists low-emitting materials under Indoor Environmental Quality. A current EQ practice question about emissions is not automatically outdated.

• Why not A: That was the v4.1 BD+C credit category. The current exam still covers low-emitting materials in EQ, but this question asks for the v5 BD+C credit category.
• Why not B: Unrelated category.
• Why not D: Project Priorities covers regional, pilot and exemplary credits.

Answer: D. A Health Product Declaration (HPD)

HPDs report product contents and associated health information. EPDs report LCA-based environmental impacts within declared boundaries. Disclosure documents inform decisions; neither one certifies a product as safe.

• Why not A: EPDs report life-cycle environmental impacts, such as global warming potential, not ingredient health information.
• Why not B: Plaques apply to buildings, not products.
• Why not C: RECs relate to renewable electricity, not product contents.

Answer: A. Dropping the unnecessary finish

Source reduction, meaning not using material in the first place, sits above reuse and recycling because it avoids both the waste and the impacts of making the material.

• Why not B: Recycling manages waste after it's created.
• Why not C: Landfilling is the least preferred option.
• Why not D: Buying more to recycle more increases waste.

Review topic: Waste hierarchy. Source: EPA, Sustainable Management of Construction and Demolition Materials

Answer: C. Deconstruction for reuse

Reuse keeps a product in its original form and function, which generally saves more resources than recycling. Careful deconstruction is what makes reuse possible.

• Why not A: Recycling breaks materials down into raw material; these doors stay intact.
• Why not B: The doors are being kept in use.
• Why not D: Crushing destroys the doors' original form.

Review topic: Reuse vs. recycling. Source: EPA, Sustainable Management of Construction and Demolition Materials

Answer: C. 75%

Total waste = 18 + 27 + 15 = 60 tons. Kept from landfill = 18 + 27 = 45 tons. 45 ÷ 60 = 75%. This is an exercise ratio, not a LEED credit calculation.

• Why not A: That's the landfilled share (15 ÷ 60).
• Why not B: 45 is the tonnage kept from landfill, not the percentage.
• Why not D: That divides 45 by 15 instead of by the total.

Answer: B. VOC emissions testing results, from a third-party certification or qualified lab report

v5 bases compliance on VOC emissions testing (to the CDPH standard method), shown by third-party certification or a qualified lab report. How much VOC is in the can and how much it emits into the room are different questions.

• Why not A: The v5 credit is based on emissions testing, not content claims.
• Why not C: Recycled content doesn't show emissions performance.
• Why not D: Odor isn't a reliable measure of emissions.

Review topic: Low-emitting materials evidence. Source: USGBC, LEED v5 BD+C — Low-Emitting Materials

Answer: D. Embodied carbon comes from materials and construction over their life cycle; operational carbon comes from running the building

Embodied carbon covers emissions associated with construction materials over their life cycle, including manufacturing, transport, installation, maintenance and disposal; operational carbon covers emissions from energy use and refrigerants during operation. v5 requires embodied carbon accounting on every BD+C project, alongside its operational carbon planning. Its MR prerequisite uses a defined cradle-to-gate (A1-A3) boundary, which is narrower than the full embodied-carbon life cycle.

• Why not A: That swaps the two terms.
• Why not B: They cover different emission sources.
• Why not C: Renewable power affects future operations, not emissions that already happened in manufacturing.

Answer: B. At least 25 feet (7.5 meters)

Designated outdoor smoking areas must be at least 25 feet (7.5 meters) from entries, outdoor air intakes and operable windows, or as far as local codes allow.

• Why not A: Too close.
• Why not C: Fifty feet exceeds the stated minimum; it is not the minimum the question asks for.
• Why not D: One hundred feet exceeds the stated minimum; it is not the minimum the question asks for.

Review topic: No smoking. Source: USGBC, LEED v5 BD+C — No Smoking or Vehicle Idling

Answer: A. Prohibiting vehicle idling on site

v5 renamed the prerequisite No Smoking or Vehicle Idling and added an on-site vehicle-idling prohibition, communicated to occupants with enforcement or signage. In v4.1 it was Environmental Tobacco Smoke Control.

• Why not B: Indoor smoking is prohibited.
• Why not C: Outdoor smoking rules remain.
• Why not D: School projects prohibit all smoking on site.

Answer: B. Remove or replace the source of the fumes

EPA describes source control as usually the most effective way to improve indoor air quality. Removing or reducing the source beats diluting or masking it.

• Why not A: Masking adds more chemicals without removing the source.
• Why not C: Lighting doesn't affect air contaminants.
• Why not D: Particle filters don't remove most gases.

Review topic: Source control. Source: EPA, Improving Indoor Air Quality

Answer: D. No smoking, extreme heat protection, HVAC protection, source control, pathway interruption, housekeeping and scheduling

The v5 prerequisite lists those seven areas for the construction and preoccupancy phases. Its intent covers both construction workers and future occupants.

• Why not A: The prerequisite covers much more than dust.
• Why not B: Practices cover construction and preoccupancy.
• Why not C: Noise isn't one of the listed areas.

Answer: C. Have the facilities team follow its smoke-response plan, check air conditions, and adjust ventilation and filtration for the event

EPA's commercial-building guidance calls for smoke-event planning, indoor and outdoor air monitoring, appropriate HVAC and filtration adjustments, and keeping windows closed when outdoor smoke threatens indoor air. Settings depend on the building and event; the facilities team should follow its response plan. v5's climate resilience assessment explicitly lists wildfire smoke as a hazard to consider.

• Why not A: Outdoor air can be worse than indoor air during a smoke event.
• Why not B: That ignores normal ventilation needs.
• Why not D: Temperature doesn't measure smoke.

Answer: A. The filter is better at capturing particles in the tested size ranges

Minimum Efficiency Reporting Value (MERV) reports how well a filter captures particles between 0.3 and 10 microns. The higher the MERV, the better it traps those particle sizes.

• Why not B: MERV measures capture efficiency, not service life.
• Why not C: MERV rates particle capture, not gases.
• Why not D: MERV measures particle-capture efficiency, not fan-energy consumption.

Review topic: Filtration. Source: EPA, What is a MERV rating?

Answer: B. Shading and glare control, along with thermal comfort, rather than simply adding more glass

Daylight is valuable, but it has to be balanced with glare control and thermal comfort. The current exam specifications list glare control alongside daylight under lighting.

• Why not A: More glass can make glare and heat worse.
• Why not C: Light level alone doesn't capture glare or overheating.
• Why not D: That gives up daylight and views rather than balancing them with glare control and thermal comfort.

Answer: A. Sound isolation and acoustic privacy matched to how the meeting room is used

Acoustic design depends on the use of each space. A confidential room needs noise isolation from its neighbors; the exam specifications list acoustics and noise isolation under sound.

• Why not B: Different spaces have different acoustic needs.
• Why not C: Lighting doesn't change sound transmission.
• Why not D: Energy performance doesn't measure acoustics.

Answer: C. Views of outdoor greenery and live plants in occupied spaces

Biophilic design connects people with nature through things like live plants, natural materials and views. The current exam specifications list adaptable environments, live plants and quality of views under biophilic design.

• Why not A: RECs relate to energy, not occupant connection with nature.
• Why not B: That's a climate strategy.
• Why not D: That's a water management strategy.

Answer: D. Evaluating additional inclusive design strategies to address those barriers

v5 adds Accessibility and Inclusion as an EQ credit, encouraging design that goes beyond minimum code requirements. The exam specifications list inclusive design under that topic.

• Why not A: Meeting code doesn't remove every barrier people experience.
• Why not B: Their feedback is what identified the barriers.
• Why not C: A single feature doesn't address wayfinding and sensory needs.

Answer: C. No; school projects must prohibit all smoking on site

The v5 prerequisite has a specific rule for schools: prohibit all smoking on site. The 25-foot distance applies to designated smoking areas on other project types.

• Why not A: The 25-foot rule applies to other project types; schools prohibit smoking on site entirely.
• Why not B: Signage doesn't make on-site smoking acceptable at a school.
• Why not D: Covering the area doesn't change the school rule.
