QUESTION: 17

A LEED Building Design and Construction: New Construction office building's HVAC system includes hot water from a central utility plant. The central utility plant is owned and operated by a management company. The office pays a flat fee for hot water, included as part of the lease. The management company does not meter or invoice for actual hot water consumption. For the project to meet the requirements for Energy and Atmosphere Prerequisite, Building-Level Energy Metering, an energy meter must be installed for

natural gas
hot water at the main service point
nothing, because the flat fee is included as part of the lease
nothing, because the energy source is outside of the project's scope

Answer(s): B

Explanation:

An energy meter must be installed for hot water at the main service point for the project to meet the requirements for Energy and Atmosphere Prerequisite, Building-Level Energy Metering. According to the LEED v4 BD+C Reference Guide, this prerequisite requires that "all energy sources used by the building must be metered or submetered" 1. The hot water from the central utility plant is an energy source used by the building, even if it is not directly paid by the office. Therefore, it must be metered at the point where it enters the building. The other options are incorrect because natural gas is not an energy source used by the building in this case, and the flat fee or the ownership of the energy source do not exempt the project from the metering requirement.

QUESTION: 18

LEED project boundaries that include multiple similar buildings which are all eligible for certification can be registered as which of the following?

Batch project
Group project
Master Site project
Neighborhood project

Answer(s): B

Explanation:

LEED project boundaries that include multiple similar buildings which are all eligible for certification can be registered as a group project. A group project allows multiple buildings (or interior spaces within multiple buildings) on a shared site to be certified as a single LEED project. These projects must meet the criteria outlined in the LEED Campus Guidance for Projects on a Shared Site, such as having the same construction contract, ownership, management, space type, rating system, and compliance paths. A group project will receive one certification and rating for the entire group.

QUESTION: 19

Which system is eligible for the Energy and Atmosphere Credit, Renewable Energy Production?

Ground-source heat pumps
Tidal-based electrical production
Municipal solid waste combustion
Passive solar and daylighting strategies

Answer(s): B

Explanation:

Tidal-based electrical production is eligible for the Energy and Atmosphere Credit, Renewable Energy Production. This credit rewards projects that use renewable energy systems to offset building energy cost. According to the LEED v4 BD+C Reference Guide, renewable energy systems are defined as "those that use resources that are naturally replenished within a 100-year or shorter cycle and that are greenhouse gas neutral on an annual basis" 1. Tidal-based electrical production meets this definition, as it uses the kinetic energy of the tides to generate electricity without emitting greenhouse gases. The other options are not eligible for this credit, as ground-source heat pumps are not considered renewable energy systems, municipal solid waste combustion is not greenhouse gas neutral, and passive solar and daylighting strategies do not offset building energy cost.

QUESTION: 20

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

Which of the following credits can the LEED AP submit towards certification?
Materials and Resources Credit, Building Product Disclosure and Optimization - Sourcing of Raw Materials
Materials and Resources Prerequisite, Construction and Demolition - Waste Management Planning
Materials and Resources Credit, Building Product Disclosure and Optimization - Material Ingredients
Materials and Resources Credit, Building Product Disclosure and Optimization - Environmental Product Declarations

Answer(s): A

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 materials. 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 criteria. 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-mingled. 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 scope.
