LEED Integrative Process and Strategies 3 — Questions and Answers
Question 1: Under LEED's Integrative Process credit, teams must analyze how water-related systems interact. Which of the following cross-system interactions is specifically encouraged?
- Using stormwater to offset potable irrigation and link that demand reduction to mechanical system sizing (Correct answer)
- Replacing all potable fixtures with greywater systems regardless of local code
- Eliminating irrigation entirely to comply with Water Efficiency prerequisites
- Metering only domestic hot water to track Energy and Atmosphere performance
Correct answer: Using stormwater to offset potable irrigation and link that demand reduction to mechanical system sizing
LEED's IP credit asks teams to analyze how reducing site water demand (e.g., via stormwater reuse) can reduce the size of mechanical systems that treat or heat water.
Question 2: What is the correct sequence of the LEED Integrative Process credit activities?
- Design → Discover → Implement → Occupy
- Discover → Design → Implement → Occupy (Correct answer)
- Implement → Design → Discover → Occupy
- Occupy → Discover → Design → Implement
Correct answer: Discover → Design → Implement → Occupy
LEED's integrative process flows from Discovery (pre-design analysis) through Design, then Implementation, and finally Occupancy and performance feedback.
Question 3: A design team is evaluating natural ventilation strategies. Which integrative process action most supports identifying whether natural ventilation is feasible?
- Reviewing the final mechanical submittal for damper schedules
- Conducting a pre-design analysis of prevailing winds, site obstructions, and outdoor air quality (Correct answer)
- Specifying MERV-13 filters in lieu of a site analysis
- Deferring the decision to the contractor's value engineering phase
Correct answer: Conducting a pre-design analysis of prevailing winds, site obstructions, and outdoor air quality
Pre-design analysis of local climate data, wind patterns, and outdoor air quality is necessary to determine whether natural ventilation is viable before design commences.
Question 4: Which LEED v4 prerequisite directly requires an Owner's Project Requirements (OPR) and Basis of Design (BOD) document?
- EA Prerequisite: Fundamental Commissioning and Verification (Correct answer)
- WE Prerequisite: Indoor Water Use Reduction
- SS Prerequisite: Construction Activity Pollution Prevention
- MR Prerequisite: Storage and Collection of Recyclables
Correct answer: EA Prerequisite: Fundamental Commissioning and Verification
The EA Fundamental Commissioning prerequisite requires that the OPR and BOD be developed and used to verify that systems meet owner intent.
Question 5: An integrative process team discovers that a green roof could reduce stormwater runoff by 60% and also cut cooling loads by 8%. This discovery exemplifies:
- A single-benefit design strategy
- A multi-benefit strategy generating synergies across Sustainable Sites and Energy categories (Correct answer)
- A prerequisite compliance shortcut
- An indoor environmental quality improvement only
Correct answer: A multi-benefit strategy generating synergies across Sustainable Sites and Energy categories
A green roof that simultaneously manages stormwater and reduces cooling load is a classic multi-benefit strategy spanning Sustainable Sites and Energy and Atmosphere categories.
Question 6: Which metric is typically set during the discovery phase of an integrative process to guide energy-related design decisions?
- Final LEED scorecard point total
- Energy use intensity (EUI) reduction target (Correct answer)
- Construction waste diversion percentage
- Occupant satisfaction survey baseline
Correct answer: Energy use intensity (EUI) reduction target
Setting an EUI reduction target early in discovery gives the team a quantitative goal that drives decisions about envelope, systems, and renewable energy throughout design.
Question 7: During an integrative process charrette, the lighting designer suggests reducing plug loads through occupant behavior programs. Why is this relevant to HVAC sizing in an integrative process?
- Plug load reductions are unrelated to HVAC sizing
- Lower internal heat gains from plug loads reduce cooling loads, potentially allowing smaller cooling equipment (Correct answer)
- Behavior programs are addressed only in Operations and Maintenance manuals
- Plug load reductions only affect the electrical panel schedule
Correct answer: Lower internal heat gains from plug loads reduce cooling loads, potentially allowing smaller cooling equipment
Reducing internal heat gains from plug loads lowers cooling demand, which in an integrative process analysis can justify downsizing HVAC equipment and reducing capital cost.
