LEED - Leadership in Energy and Environmental Design Integrative Process and Strategies Questions and Answers — Questions and Answers
Question 1: During the 'Discovery' phase of the Integrative Process, what is the primary purpose of performing a preliminary water budget analysis?
- To select specific water-efficient fixture models for procurement.
- To finalize the landscape irrigation system design and specifications.
- To inform the Owner's Project Requirements (OPR) and Basis of Design (BOD) by understanding water demand and potential non-potable sources. (Correct answer)
- To meet the requirements for the Outdoor Water Use Reduction prerequisite.
Correct answer: To inform the Owner's Project Requirements (OPR) and Basis of Design (BOD) by understanding water demand and potential non-potable sources.
The preliminary water budget analysis, conducted before the schematic design is complete, is a discovery tool. Its purpose is to quantify the project's potential water demand (indoor, outdoor, process) and assess available non-potable water sources. This early analysis helps the team identify synergies and inform the OPR and BOD with realistic, high-performance water-related goals.
Question 2: A project team is pursuing the Integrative Process (IP) credit. Before completing the schematic design, they must perform a 'simple box' energy model. Which of the following is a key objective of this analysis?
- To calculate the final Energy Use Intensity (EUI) for the building to demonstrate code compliance.
- To assess strategies related to massing, orientation, and basic envelope attributes to inform the design. (Correct answer)
- To select the specific HVAC system and renewable energy equipment.
- To generate construction documents for the building's thermal envelope.
Correct answer: To assess strategies related to massing, orientation, and basic envelope attributes to inform the design.
The 'simple box' energy model is a preliminary analysis used early in the design process (before schematic design is complete) to understand the building's energy loads and how major design decisions will impact energy consumption. It allows the team to assess and question default assumptions about massing, orientation, envelope, lighting, and other factors to find opportunities for energy load reduction.
Question 3: Which of the following best describes the relationship between the 'Discovery' and 'Implementation' phases of the Integrative Process credit?
- The 'Discovery' phase involves value engineering to cut costs, while the 'Implementation' phase focuses on achieving LEED points.
- The 'Discovery' phase is for architects and engineers, while the 'Implementation' phase is for contractors and subcontractors.
- The 'Discovery' phase is optional, but the 'Implementation' phase is required for credit achievement.
- The 'Discovery' phase involves analysis that informs the design decisions documented in the 'Implementation' phase. (Correct answer)
Correct answer: The 'Discovery' phase involves analysis that informs the design decisions documented in the 'Implementation' phase.
The LEED IP credit is structured into two main parts: Discovery and Implementation. The Discovery phase requires teams to perform analyses (like the simple box energy model and water budget analysis) to find opportunities for synergy and improved performance. The Implementation phase requires the team to document how the findings from the Discovery phase actually informed the project's design, including the OPR and BOD.
Question 4: A project team is holding its initial goal-setting workshop as part of the Integrative Process. Which of these activities is MOST critical to the success of this workshop?
- Finalizing the material specifications for the entire project.
- Ensuring all key project team members and stakeholders are present and engaged. (Correct answer)
- Presenting a fully completed schematic design for approval.
- Receiving binding cost estimates from the general contractor.
Correct answer: Ensuring all key project team members and stakeholders are present and engaged.
The intent of the Integrative Process is to foster collaboration and communication among all project stakeholders from the very beginning. The goal-setting workshop is a key event where findings from preliminary analyses are shared, performance targets are set, and responsibilities are identified. The success of this collaborative effort depends on having all principal team members and stakeholders engaged in the process.
Question 5: The LEED Integrative Process is based on a standard developed by which organization?
- American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE)
- U.S. Environmental Protection Agency (EPA)
- American National Standards Institute (ANSI) (Correct answer)
- International Organization for Standardization (ISO)
Correct answer: American National Standards Institute (ANSI)
The LEED v4 credit for Integrative Process is based on the principles outlined in the ANSI Consensus National Standard Guide 2.0 for Design and Construction of Sustainable Buildings and Communities. This guide provides the framework for practicing integrative design.
Question 6: In a scenario-based application of the Integrative Process for a new office building in a temperate climate, the energy analysis reveals significant potential for passive heating and cooling. How should this finding be documented to meet the IP credit requirements?
- By including the energy model output files in the final LEED submission.
- By issuing a change order to the mechanical engineer.
- By showing how the analysis influenced the building's orientation, massing, and window selection in the OPR and BOD. (Correct answer)
- By achieving at least 10% energy cost savings in the Optimize Energy Performance credit.
Correct answer: By showing how the analysis influenced the building's orientation, massing, and window selection in the OPR and BOD.
A core requirement of the Integrative Process is to document how the early analyses (Discovery) inform the project's design and operational decisions (Implementation). The findings from the energy analysis, such as the potential for passive strategies, must be shown to have influenced the Owner's Project Requirements (OPR) and the Basis of Design (BOD), specifically impacting decisions about the building's form and envelope.
