Free LEED AP Building Design Construction (LEED AP BD C) Exam Questions and Answers
LEED AP Building Design Construction (LEED AP BD C) is one of the USGBC tests covered here. Three organisations are involved and it is worth knowing which does what: USGBC develops the LEED rating system, IWBI develops the WELL Building Standard, and GBCI — a separate body from both — administers the exams. LEED Green Associate is the foundation credential and the only one with no prerequisite: 100 multiple-choice questions in two hours, needing 170 points out of 200, sat at a Prometric centre or online-proctored, and renewed with 15 continuing-education hours every two years. The specialty AP credentials sit above it and carry heavier continuing-education requirements.
If you searched for LEED AP Building Design Construction (LEED AP BD C) dumps, an ExamTopics discussion or a free PDF, this is the question bank for it: practice questions with verified answers and explanations, a timed practice test and updates whenever USGBC changes the exam.

Question #1
A project team is comparing a reinforced concrete frame with a mass timber frame for a 5-story residential building using a whole-building life-cycle assessment. The results are reported in kg CO2e per square foot of floor area. Which impact category do these results represent?
Correct answer: A
Explanation
Results expressed in carbon dioxide equivalents (CO2e) quantify global warming potential, the category used to represent embodied carbon in a whole-building life-cycle assessment. Acidification is reported in SO2 equivalents, eutrophication in nitrogen or phosphate equivalents, and ozone depletion in CFC-11 equivalents.

Question #2
What is the minimum gross floor area required for a project to pursue LEED BD+C certification under the minimum program requirements?
Correct answer: B
Explanation
The project size minimum program requirement for LEED BD+C is a gross floor area of at least 1,000 ft² (93 m²). Smaller buildings are not eligible regardless of their performance.

Question #3
A landscape architect is reviewing the plan for an office campus in a hot, arid climate. About 40% of the landscaped area is turf irrigated by spray heads using municipal potable water. The owner wants to reduce irrigation demand, not just the use of potable water. Which strategy would MOST reduce irrigation demand?
Correct answer: C
Explanation
Demand falls most when plants need less water to begin with, and efficient drip delivery to native plantings cuts it further. Harvested rainwater only changes the source and still meets the same turf demand. A controller or mulch trims waste but keeps the high-demand turf.

Question #4
A design team is demonstrating thermal comfort for a 20,000 ft² (1,858 m²) open office using ASHRAE Standard 55. Which set of factors must be addressed in the analysis?
Correct answer: C
Explanation
ASHRAE Standard 55 defines thermal comfort from six factors: air temperature, radiant temperature, air speed, humidity, metabolic rate and clothing insulation. Carbon dioxide relates to ventilation and illuminance relates to lighting, so neither belongs in a thermal comfort analysis.

Question #5
A design team is modeling a 90,000 ft² (8,360 m²) office building in a cold climate. The early energy model shows that space heating is the largest end use, driven mainly by losses through a curtain wall with a 55% window-to-wall ratio and poor air tightness. The mechanical engineer proposes specifying a condensing boiler with the highest efficiency available. Which action should the team take FIRST to improve energy performance?
Correct answer: B
Explanation
The stem says the heating load comes mainly from the glazed curtain wall and poor air tightness, so cutting that load comes first. A smaller load lets the team then pick smaller, efficient heating equipment. Choosing the boiler now would size it to a load that is too large. Energy recovery and photovoltaics do not touch the envelope losses that drive the problem.

Question #6
A school district is choosing among four sites for a new 60,000 ft² (5,575 m²) elementary school and wants to avoid developing sensitive land. Which site is the BEST choice?
Correct answer: A
Explanation
Protecting sensitive land means putting the development footprint on previously developed land rather than on prime farmland, wetlands or floodplains. The former retail site is already disturbed. Keeping a garden, an outdoor classroom or a raised floor level softens the impact but still develops sensitive land, which is the trap in the other three sites.

Question #7
During schematic design of a 120,000 ft² (11,150 m²) laboratory building, the owner asks the team to follow an integrative design process. Which approach BEST reflects that process?
Correct answer: B
Explanation
An integrative process brings the stakeholders together early so that options affecting several systems, such as massing, envelope and HVAC, are tested together before any are fixed. Fixing massing first, or reconciling separate targets later, makes the work sequential and misses the synergies. A constructability review of the construction documents is useful, but it comes too late to shape the design.

Question #8
A project team is preparing a site assessment for a four-story outpatient clinic on a 3-acre (1.2-ha) lot. The team wants the assessment to support later decisions on rainwater management. Which data should the assessment collect for this purpose?
Correct answer: C
Explanation
A site assessment records existing natural conditions, such as soils and hydrology, before design begins. Infiltration rates and depth to groundwater tell the team whether rainwater can be infiltrated on site. Irrigation demand, roof reflectance and light trespass depend on design choices not yet made, so they are not existing site conditions.
