A commercial new construction project consists of mixed space usage. When deciding which LEED rating system to use, the LEED AP should follow which of the following rules?
Correct Answer: D
According to the LEED v4: Building Design + Construction Guide, the 40/60 rule provides guidance for making a decision when several rating systems appear to be appropriate for a project. To use this rule, first assign a rating system to each square foot or square meter of the building, and then choose the most appropriate rating system based on the resulting percentages. The entire gross floor area of a LEED project must be certified under a single rating system and is subject to all prerequisites and attempted credits in that rating system, regardless of mixed construction or space usage type. If a rating system is appropriate for less than 40% of the gross floor area of a LEED project building or space, then that rating system should not be used. If a rating system is appropriate for more than 60% of the gross floor area of a LEED project building or space, then that rating system should be used. If an appropriate rating system falls between 40% and 60% of the gross floor area, project teams must independently assess their situation and decide which rating system is most applicable1.

Question 132
The energy-related systems analysis for Integrative Process credit for Core and Shell projects should include all system loads and occupants required by which Energy and Atmosphere prerequisite?
Correct Answer: C
Detailed The energy-related systems analysis must align with the requirements of the Minimum Energy Performance prerequisite. This prerequisite ensures that energy systems are modeled to optimize performance and meet baseline criteria outlined in ASHRAE 90.1-2010 (or applicable standard). Including all system loads and occupants provides a comprehensive understanding of energy demands.
Question 133
The design team and project owner decided not to pursue Energy and Atmosphere Credit, Enhanced Commissioning, but would hire a Commissioning Authority (CxA) to oversee the requirements for Energy andAtmosphere Prerequisite, Fundamental Commissioning and Verification. What is a required responsibility for the CxA to achieve the stated objective?
Correct Answer: D
Explanation According to the LEED v4: Building Design + Construction Guide, the Energy and Atmosphere Prerequisite, Fundamental Commissioning and Verification, requires the project to hire a Commissioning Authority (CxA) to oversee the commissioning process for the mechanical, electrical, plumbing, and renewable energy systems and assemblies. The CxA must have documented commissioning authority experience in at least two building projects, and must not be an employee of the design or construction firms, although they may be contracted through them.The CxA must report the results, findings, and recommendations directly to the owner1. One of the required responsibilities for the CxA to achieve the prerequisite is to verify installation and performance of the commissioned systems.This includes conducting siteobservations and spot-checking of equipment installation, performing functional performance testing of the systems, verifying system performance by reviewing testing and balancing reports, and preparing a summary commissioning report of the activities and results1. The other choices are not required responsibilities for the CxA to achieve the prerequisite, but they are additional responsibilities for the CxA to achieve the Energy and Atmosphere Credit, Enhanced Commissioning, which goes beyond the prerequisite by including more systems, more verification activities, and more documentation.These additional responsibilities are2: * Verify that training requirements are completed. This includes reviewing training plans, agendas, and materials, and verifying that the training delivery and documentation are completed and consistent with the owner's project requirements (OPR). * Develop systems manual for the commissioned systems. This includes compiling and reviewing the systems manual that provides the necessary information for operating and maintaining the commissioned systems. * Review contractor submittals for the commissioned systems. This includes reviewing the design intent and basis of design documentation, and providing feedback on the contractor submittals related to the commissioned systems, such as shop drawings, product data, and samples.

Question 134
In the calculations for Water Efficiency Credit, Outdoor Water Use Reduction, food gardens
Correct Answer: C
Explanation Food gardens may be included or excluded from the calculations for Water Efficiency Credit, Outdoor Water Use Reduction, as per the project team's discretion. If included, food gardens must be calculated using 100% potable water. If excluded, food gardens must be irrigated with 100% captured rainwater, recycled graywater, or water treated and conveyed by a public agency specifically for nonpotable uses.References: * Outdoor Water Use Reduction credit in LEED BD+C: New Construction v4.1 - LEED v4.11 * LEED v4 BD+C WE Guide2
Question 135
What are the three phases within the Integrative Process Credit, Integrative Process?
Correct Answer: B
The Integrative Process credit under the LEED BD+C v4 rating system encourages the coordination of all the project team members, starting from the predesign phase, to discover unique opportunities for project design, enhanced building performance, and green features. The three phases within the Integrative Process Credit are: Discovery phase: This involves investigating at least two energy-related and several water-related sustainable design strategies prior to the end of schematic design1. Design and Construction (implementation) phase: This requires the project teams to turn their findings into reality2. Occupance, Operations, and Performance Feedback phase: This phase involves the evaluation of the implemented strategies and their effectiveness3.
