Correct Answer: C
Explanation Discussing the project goals to help identify the credits and options that the team should attempt is an example of developing the LEED Scorecard.The LEED Scorecard is a tool that shows the potential points that a project can achieve under each credit category of the LEED rating system1.Developing the LEED Scorecard involves selecting the mostappropriate credits and options based on the project's goals, location, budget, and design2.The scorecard helps the project team track their progress and prioritize their actions throughout the design and construction process1.References: * LEED scorecard | U.S. Green Building Council * LEED v4: Building Design + Construction Guide - U.S. Green Building Council
Question 257
In order for a product to contribute to Materials and Resources Credit, Building Product Disclosure and Optimization, Environmental Product Declarations, Option 1. Environmental Product Declaration, the product needs to be
Correct Answer: D
The correct answer is D. critically reviewed life-cycle assessment conforming to ISO 14044. This is because: * Option 1 of this credit requires the use of products that have environmental product declarations (EPDs), which are documents that provide information about the environmental impact of a product throughout its life cycle1. * EPDs are based on life-cycle assessments (LCAs), which are systematic analyses of the environmental aspects and potential impacts of a product from raw material extraction to disposal2. * LCAs must conform to the international standard ISO 14044, which specifies the principles and framework for conducting and reporting LCAs3. LCAs must also be critically reviewed by an independent panel of experts to ensure their validity and reliability4. * The other options are not relevant for this credit. FSC certification is a label that indicates that a wood product comes from a well-managed forest5. Cradle-to-cradle certification is a label that indicates that a product is designed for circular economy, with minimal waste and toxicity. CSR is a report that discloses the social and environmental performance of a company.
Question 258
In the calculations for Water Efficiency Credit, Outdoor Water Use Reduction, food gardens
Correct Answer: C
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.

Question 259
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
Explanation 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.References: LEED v4: Building Design + Construction Guide, LEED Rating System Selection Guidance1
Question 260
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 and Atmosphere Prerequisite, Fundamental Commissioning and Verification. What is a required responsibility for the CxA to achieve the stated objective?
Correct Answer: D
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 site observations 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.
