LEED-AP-BD+C Exam Dumps - LEED AP Building Design + Construction (LEED AP BD+C)

For Energy and Atmosphere (EA) Credit: Advanced Energy Metering, any individual energy end uses that represent 10% or more of the total annual energy consumption must be metered (A). This credit promotes ongoing energy management and helps identify large energy-consuming systems for efficiency improvements. Metering data from major end uses can provide insights into energy patterns, facilitating targeted actions to reduce consumption.

According to the LEED v4: Building Design + Construction Guide, the owner or an owner’s representative must be a member of the integrated project team for the Integrative Process Prerequisite, Integrative Project Planning and Design. The owner or an owner’s representative is responsible for establishing the project’s vision, goals, budget, and schedule, as well as defining the owner’s project requirements (OPR) and participating in the design charrettes and reviews1. The owner or an owner’s representative also plays a key role in ensuring the continuity and alignment of the project’s performance and environmental objectives throughout all phases of the project1.

The other choices are not mandatory members of the integrated project team, although they may be involved in the integrative process depending on the project’s scope and needs. The general contractor is typically hired after the design phase and may not be involved in the predesign and schematic design analyses required by the prerequisite1. A LEED AP is a professional who has demonstrated knowledge and experience in applying the LEED rating system, but is not required to be part of the integrated project team, although it is recommended and rewarded by the LEED credit, Integrative Process1. The project’s mechanical engineer is one of the possible design consultants who may contribute to the integrative process, especially for the energy-related systems analysis, but is not required to be part of the integrated project team1.

An economic advantage of the infill site is that it reduces the need for new utility infrastructure. This is because the infill site is located within an existing urban area that already has access to water, sewer, electricity, and other utilities1. The developer can save on the costs of extending or installing new utility lines and services to the rural greenfield site, which may not have adequate or reliable utility infrastructure2. The other options are not economic advantages, but rather environmental benefits of the infill site. Protecting greenfields and farmland, preserving habitat and natural resources, and reducing potential damage to an existing stream are all positive outcomes of avoiding development on the rural greenfield site, but they do not directly translate into monetary savings for the developer3.

Average number of occupants standing or seated

To identify the regularly occupied spaces on a project, the LEED consultant should consider the average number of occupants standing or seated in each space, as this is the criterion used by the LEED Reference Guide for Green Building Design and Construction, 20091. Regularly occupied spaces are defined as areas where workers are seated or standing as they work (or perform regular tasks) inside a building2. The typical duration of occupancy in each space per day is not necessarily relevant, as some spaces may be used intermittently but still qualify as regularly occupied2. The rate of outdoor air provided per person and the fire ratings of installed wall and ceiling assemblies are not related to the definition of regularly occupied spaces, but rather to other credits such as Indoor Environmental Quality or Fire and Life Safety.

The commissioning (Cx) agent must have completed the commissioning process activities for a minimum of two similar projects in order to meet the minimum qualifications for Energy and Atmosphere Prerequisite, Fundamental Commissioning and Verification. This is stated in the LEED v4 Building Design + Construction Guide, under the section “Energy and Atmosphere Credits Overview”. The guide also provides examples of similar projects that can be used as references for commissioning.

Rainwater collected from the building roof would be the most appropriate nonpotable water source for use in a cooling tower. This is because rainwater is generally cleaner than other nonpotable sources and does not require extensive treatment before use. Additionally, using rainwater can help to reduce stormwater runoff, providing an additional environmental benefit.References: LEED AP Building Design + Construction (LEED AP BD+C) V4 resources 1

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.

How to choose the right materials for a LEED project? - GBCE

If a transporter lacks chain-of-custody (CoC) certification for certified wood products, the design team should recalculate the percentage of certified wood and classify the affected wood as non-certified (B). This approach follows LEED's requirements for accurate reporting on certified materials. LEED requires all certified wood to maintain CoC certification from the forest to the project site, so any deviation affects credit calculations. Submitting a CIR (A) isn’t needed as the LEED rules are clear on this matter, and removal (D) may not be feasible or cost-effective.
