Q1.What is an Environmental Product Declaration (EPD)?
A.A government label for products with recycled contentB.A third-party verified document disclosing a product's life cycle environmental impactsC.A manufacturer's self-certification that a product is environmentally friendlyD.An OSHA document listing chemical hazards in building materialsB. A third-party verified document disclosing a product's life cycle environmental impactsExplanation: An Environmental Product Declaration (EPD) is a standardized, third-party verified document (ISO 14025/EN 15804) that discloses quantified environmental information about a product's life cycle impacts — including global warming potential, acidification, eutrophication, and resource depletion.

Q2.What does LEED's Building Life-Cycle Impact Reduction credit reward?
A.Using materials with the highest recycled contentB.Choosing a historic renovation, abandoned building reuse, or demonstrating reduced life-cycle impacts through assessmentC.Purchasing all materials within 500 miles of the project siteD.Using zero volatile organic compound (VOC) productsB. Choosing a historic renovation, abandoned building reuse, or demonstrating reduced life-cycle impacts through assessmentExplanation: The Building Life-Cycle Impact Reduction (BLIIMR) credit encourages reuse of existing buildings and structures, which dramatically reduces the environmental impact of construction by avoiding the embodied carbon and resource extraction of new materials.

Q3.What is a Health Product Declaration (HPD)?
A.A report of indoor air quality test results after constructionB.A standardized disclosure of a product's contents, including hazardous chemicals, based on a priority chemical listC.A certification that a product is safe for occupant exposureD.An ASHRAE standard for product off-gassing limitsB. A standardized disclosure of a product's contents, including hazardous chemicals, based on a priority chemical listExplanation: An HPD (Health Product Declaration) discloses a product's full ingredient list and identifies any hazardous chemicals on priority chemical lists (e.g., REACH SVHC, California Prop 65, GreenScreen). LEED MR credits reward specifying products with HPDs to support transparency.

Q4.Construction waste diversion in LEED refers to:
A.Minimizing the amount of materials purchased to reduce leftover wasteB.Diverting construction and demolition debris from landfill through recycling, salvage, or reuseC.Documenting all material shipments to verify no hazardous waste was generatedD.Using pre-fabricated materials to reduce on-site waste generationB. Diverting construction and demolition debris from landfill through recycling, salvage, or reuseExplanation: LEED's Construction and Demolition Waste Management credit rewards projects for diverting construction waste from landfill by recycling, salvaging, or donating materials. Projects must achieve a minimum diversion rate (by weight or volume) and document quantities diverted.

Q5.What is the minimum percentage of recycled content required for a material to contribute to LEED's Building Product Disclosure credit?
A.LEED does not specify a minimum — the material must have a validated EPD or HPDB.At least 10% post-consumer recycled contentC.At least 20% total recycled contentD.At least 50% recycled content by weightA. LEED does not specify a minimum — the material must have a validated EPD or HPDExplanation: LEED's MR credits for product disclosure (EPDs, HPDs, sourcing) do not prescribe minimum recycled content percentages. Instead, they reward transparency — products must have third-party verified disclosures. Recycled content is one of many disclosure attributes but there is no minimum threshold required.
