LEED (Leadership in Energy and Environmental Design Certification) LEED Process and Integration 5 — Questions and Answers
Question 1: What is the primary goal of the LEED 'Location and Transportation' credit category?
- To reduce the building's energy use for transportation systems within the building
- To encourage site selection that reduces vehicle miles traveled and supports alternative transportation (Correct answer)
- To require electric vehicle charging stations in all parking structures
- To mandate that projects be located within walking distance of a LEED-certified building
Correct answer: To encourage site selection that reduces vehicle miles traveled and supports alternative transportation
The Location and Transportation category incentivizes site selection near transit, infill development, and walkable areas to reduce occupant reliance on private vehicles.
Question 2: Under the LEED 'Integrative Process' framework, what is the recommended sequence for design decision-making?
- Select active mechanical systems first, then optimize passive strategies around them
- Reduce loads through passive strategies first, then right-size active systems to meet remaining demand (Correct answer)
- Design for occupant comfort first, then address energy and water efficiency separately
- Complete structural design before evaluating any sustainability strategies
Correct answer: Reduce loads through passive strategies first, then right-size active systems to meet remaining demand
LEED's integrative process prioritizes passive load reduction (orientation, envelope, daylighting) before sizing active systems, resulting in smaller, more efficient mechanical equipment.
Question 3: What is a 'Basis of Design' (BOD) document and when is it typically developed in a LEED project?
- A post-occupancy report summarizing actual energy performance versus projections
- A document developed during design that describes the design strategies, assumptions, and criteria used to meet the Owner's Project Requirements (Correct answer)
- A legal document establishing the project's zoning compliance baseline
- A construction-phase document listing all materials with environmental product declarations
Correct answer: A document developed during design that describes the design strategies, assumptions, and criteria used to meet the Owner's Project Requirements
The Basis of Design is created during design to explain the reasoning behind design decisions and how they address the Owner's Project Requirements, forming a key commissioning document.
Question 4: Which LEED credit category most directly addresses reducing the urban heat island effect?
- Water Efficiency
- Sustainable Sites (Correct answer)
- Indoor Environmental Quality
- Materials and Resources
Correct answer: Sustainable Sites
The Sustainable Sites category includes credits for using high-albedo paving, vegetated roofs, and shade trees to reduce heat absorption and mitigate the urban heat island effect.
Question 5: A project team registers a LEED project but later decides to change the rating system during design. What must the team do?
- Forfeit their registration fee and re-register under the correct rating system with a new fee
- Contact GBCI to update the registration to reflect the new rating system selection (Correct answer)
- Complete certification under the original rating system, then recertify under the new one
- No action is needed; GBCI automatically assigns the correct rating system at certification
Correct answer: Contact GBCI to update the registration to reflect the new rating system selection
Teams that need to change their rating system selection must contact GBCI to update the project registration before submitting for certification review.
Question 6: What is the purpose of 'Measurement and Verification' (M&V) in LEED Energy and Atmosphere credits?
- To verify material quantities used during construction match the approved submittals
- To establish a plan for ongoing monitoring of building energy use to confirm performance after occupancy (Correct answer)
- To measure the carbon footprint of the construction process itself
- To verify that the energy model assumptions match the architectural drawings
Correct answer: To establish a plan for ongoing monitoring of building energy use to confirm performance after occupancy
Measurement and Verification credits require a plan to monitor building energy systems post-occupancy, confirming that the building performs as predicted and enabling ongoing optimization.
Question 7: Which of the following scenarios illustrates successful 'integrated design' on a LEED project?
- The mechanical engineer selects HVAC equipment independently after the architectural design is finalized
- The architect, mechanical engineer, and lighting designer collaborate in early schematic design to optimize daylighting, reduce cooling loads, and right-size HVAC together (Correct answer)
- The owner selects LEED credits to pursue without input from the design team
- The contractor installs low-VOC materials as a substitution after the design is complete
Correct answer: The architect, mechanical engineer, and lighting designer collaborate in early schematic design to optimize daylighting, reduce cooling loads, and right-size HVAC together
Integrated design requires early and ongoing collaboration among all disciplines so that decisions in one system positively influence others, maximizing efficiency and credit achievement.
