NEW QUESTION # 266
The intent of the Sustainable Sites Prerequisite, Construction Activity Pollution Prevention is to £
Answer: D
Explanation:
The intent of the Sustainable Sites Prerequisite. Construction Activity Pollution Prevention is to reduce pollution from construction activities by controlling soil erosion, waterway sedimentation and airborne dust generation. The LEED v4 Reference Guide for Building Design and Construction states that "construction activities can have significant negative impacts on the environment, both at the project site and beyond. Erosion and sedimentation can degrade water quality, damage aquatic habitats, and increase flooding risks. Airborne dust can affect air quality, human health, and visibility. Construction vehicles and equipment can generate noise, traffic, and greenhouse gas emissions"1. The project team must implement an erosion and sedimentation control (ESC) plan that conforms to the 2012 U.S. Environmental Protection Agency Construction General Permit or local equivalent, whichever is more stringent. The ESC plan must cover all construction activity on the project site, including clearing, grading, excavating, and demolition.

NEW QUESTION # 267
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?
Answer: B
Explanation:
ForLEED BD+C Energy and Atmosphere (EA) Prerequisite: Fundamental Commissioning and Verification, theCxA is responsible for verifying that building systems are properly installed and functioning correctly.
This ensures compliance with the Owner's Project Requirements (OPR)andbasis of design (BOD).
Developing a systems manual (Option D) is required for Enhanced Commissioning, not Fundamental Commissioning.
Reviewing the building after 10 months (Option B) is also part of Enhanced Commissioning, not Fundamental Commissioning.
Training verification (Option C) is beneficial but not a core responsibility for Fundamental Commissioning.
Verifying installation and performance (Option A) is the primary requirement for the CxA under Fundamental Commissioning.

NEW QUESTION # 268
The current facilities requirements (CFR) and operations and maintenance plan (OMP) required for Energy and Atmosphere Prerequisite, Fundamental Commissioning and Verification must include
Answer: B
Explanation:
The current facilities requirements (CFR) and operations and maintenance plan (OMP) are two documents that are required for the Energy and Atmosphere Prerequisite, Fundamental Commissioning and Verification. The CFR is a document that describes the owner's project requirements, such as the design intent, performance goals, and operational needs of the building. The OMP is a document that provides information and guidance on how to operate and maintain the commissioned systems and equipment. According to the LEED v4 Reference Guide for Building Design and Construction, the CFR and OMP must include the minimum outside air requirements, which are the minimum rates of outdoor air ventilation that are needed to provide acceptable indoor air quality and thermal comfort for the occupants1. The issue logs, functional performance tests, and installation verification (construction) checklists are not required to be included in the CFR and OMP, but they are part of the commissioning process and documentation.

NEW QUESTION # 269
A contractor is building a retirement community project. 30% of the building's product costs were derived from reused/salvaged materials or met recycled content criteri a. Which of the following credits can the LEED AP submit towards certification?
Answer: C
Explanation:
The Materials and Resources Credit, Building Product Disclosure and Optimization - Sourcing of Raw Materials rewards projects that use materials that have optimized extraction processes by limiting or eliminating the extraction of new resources, the reuse of materials or the use of recycled materials1. According to the LEED Reference Guide for Building Design and Construction2, the credit has two options: Option 1. Raw Material Source and Extraction Reporting and Option 2. Leadership Extraction Practices. Option 1 requires the project to use at least 20 permanently installed products from at least five different manufacturers that have publicly released a report from their raw material suppliers which include extraction locations, a commitment to long-term ecologically responsible land use, a commitment to reducing environmental harms from extraction and/or manufacturing processes, and a commitment to meeting applicable standards or programs voluntarily that address responsible sourcing criteria2. Option 2 requires the project to use products that meet at least one of the responsible sourcing criteria below for at least 25%, by cost, of the total value of permanently installed building products in the project:
Extended producer responsibility. Products purchased from a manufacturer (producer) that participates in an extended producer responsibility program or is directly responsible for extended producer responsibility.
Bio-based materials. Bio-based products must meet the Sustainable Agriculture Network's Sustainable Agriculture Standard. Bio-based raw materials must be tested using ASTM Test Method D6866 and be legally harvested, as defined by the exporting and receiving country. Exclude hide products, such as leather and other animal skin material.
Wood products. Wood products must be certified by the Forest Stewardship Council or USGBC-approved equivalent.
Materials reuse. Reused products must include salvaged, refurbished, or reused products.
Recycled content. Recycled content is the sum of postconsumer recycled content plus one-half the preconsumer recycled content, based on cost. Products meeting recycled content criteria are valued at 100% of their cost for the purposes of credit achievement calculation.
USGBC approved program. Other USGBC approved programs meeting leadership extraction criteria.
Therefore, among the given options, only Option A is relevant to the use of reused/salvaged materials or recycled content, as they can contribute to the materials reuse or recycled content criteria under Option 2. Option B is a prerequisite that requires the project to develop and implement a construction and demolition waste management plan that identifies the materials to be diverted from disposal and whether the materials will be sorted on-site or co-mingled2. Option C is a credit that requires the project to use at least 20 different permanently installed products from at least five different manufacturers that use any of the following programs to demonstrate the chemical inventory of the product to at least 0.1% (1000 ppm):
Health Product Declaration. The end use product has a published, complete Health Product Declaration with full disclosure of known hazards in compliance with the Health Product Declaration Open Standard.
Cradle to Cradle. The end use product has been certified at the Cradle to Cradle v2 Basic level or Cradle to Cradle v3 Bronze level.
REACH Optimization. The end use product is compliant with REACH Optimization criteria.
GreenScreen v1.2 Benchmark. The product's chemical ingredients are inventoried using the GreenScreen v1.2 Benchmark.
Declare. The Declare product label must indicate that all ingredients have been disclosed down to 1000 ppm.
Option D is a credit that requires the project to use at least 20 different permanently installed products that have environmental product declarations. The products must be sourced from at least five different manufacturers. The environmental product declarations must conform to ISO 14025, 14040, 14044, and EN 15804 or ISO 21930 and have at least a cradle-to-gate scope2.

NEW QUESTION # 270
A new athletic facility contains a laundry room which is adjacent to the locker rooms. Which strategy will contribute toward the Interior Cross-Contamination Prevention strategy in Indoor Environmental Quality Credit, Enhanced Indoor Air Quality Strategies?
Answer: C
Explanation:
The strategy that will contribute toward the Interior Cross-Contamination Prevention strategy in Indoor Environmental Quality Credit, Enhanced Indoor Air Quality Strategies is to provide a ventilation system specifically for the laundry facility that has no recirculating air. This is because the laundry facility is a space where hazardous gases or chemicals may be present or used, such as detergents, bleach, or fabric softeners.
According to theLEED V5Reference Guide for Building Design and Construction, the project must " sufficiently exhaust each space where hazardous gases or chemicals may be present or used (e.g., garages, housekeeping and laundry areas, copying and printing rooms), using the exhaust rates determined in EQ Prerequisite Minimum Indoor Air Quality Performance or a minimum of 0.50 cfm per square foot (2.54 l/s per square meter), to create negative pressure with respect to adjacent spaces when the doors to the room are closed.For each of these spaces, provide self-closing doors and deck-to-deck partitions or a hard-lid ceiling. "
1Therefore, option D is the correct answer. The other options will not prevent cross-contamination from the laundry facility to the locker rooms. Relocating the laundry facility to the basement (option A) may reduce the exposure of the occupants to the laundry chemicals, but it will not eliminate the possibility of cross- contamination to other spaces in the basement. Naturally ventilating the laundry space per ASHRAE 62.1-
2010 (option B) may not provide sufficient exhaust to create negative pressure and prevent cross- contamination, especially if the outdoor air quality is poor or the natural ventilation is not well designed.
Installing particle filters, with a MERV of 13 or higher or F7 (option C) may improve the air quality in the laundry space, but it will not prevent the hazardous gases or chemicals from escaping to the adjacent spaces through the ventilation system or the gaps in the doors or ceiling.References:LEED V5Reference Guide for Building Design and Construction, p.6881; ASHRAE Standard 62.1-2010, Section 6.2.52
