81.

In order to meet the requirements of Option 1 of EA Credit–Enhanced Refrigerant Management, what is the maximum Global Warming Potential (GWP) allowed for refrigerants? 

  • Less than 50

  • At least 60

  • Less than 100

  • Greater than 40 

Correct answer: Less than 50

EA Credit–Enhanced Refrigerant Management, Option 1, requires project teams either to refrain from using refrigerants or to use only refrigerants that have an ozone depletion potential of 0 and a global warming potential of less than 50. 

Any GWP of 50 or greater would not meet the requirements for this credit. 

82.

Which of the following is true for a project team that is hoping to earn LT Credit–Reduced Parking Footprint but hasn't earned either LT Credit–Surrounding Density and Diverse Uses or LT Credit–Access to Quality Transit?

  • The team can earn LT Credit–Reduced Parking Footprint if they reduce their parking capacity by 20% from the baseline

  • The team cannot earn LT Credit–Reduced Parking Footprint

  • The team must earn LT Credit–Bicycle Facilities to be eligible for LT Credit–Reduced Parking Footprint

  • The team can earn LT Credit–Reduced Parking Footprint if they reduce their parking capacity by 10% from the baseline

Correct answer: The team can earn LT Credit–Reduced Parking Footprint if they reduce their parking capacity by 20% from the baseline

Projects that have not achieved LT Credit–Surrounding Density and Diverse Uses or LT Credit–Access to Quality Transit can still earn one point in LT Credit–Reduced Parking Footprint by reducing their parking capacity by 20% from the baseline. Reducing it by 40% would provide two points.

The team can earn LT Credit–Reduced Parking Footprint and isn't required to achieve LT Credit–Bicycle Facilities first. A reduction of 10% is not enough to earn LT Credit–Reduced Parking Footprint. 

83.

What is the purpose of the commissioning process?

  • To support the design, construction, and eventual operation of a project that meets the owner’s project requirements for energy, water, indoor environmental quality, and durability

  • To develop the OPR, BOD, and project design 

  • To reduce the environmental and economic harms of excessive energy use by achieving a minimum level of energy efficiency for the building and its systems

  • To reduce stratospheric ozone depletion

Correct answer: To support the design, construction, and eventual operation of a project that meets the owner’s project requirements for energy, water, indoor environmental quality, and durability

The intent of the commissioning process and of EA Prerequisite–Fundamental Commissioning and Verification is to support the design, construction, and eventual operation of a project that meets the owner’s project requirements for energy, water, indoor environmental quality, and durability.

The OPR, the BOD, and the project design should have already been created by the time of commissioning; one of the steps completed by the commissioning authority is to review these documents. Reducing the environmental and economic harms of excessive energy use by achieving a minimum level of energy efficiency for the building and its systems is the intent of EA Prerequisite–Minimum Energy Performance. Reducing stratospheric ozone depletion is the intent of EA Prerequisite–Fundamental Refrigerant Management. 

84.

To comply with EA Prerequisite–Fundamental Commissioning and Verification, which of the following is the commissioning authority not responsible for? 

  • Develop the OPR and BOD 

  • Review the OPR, BOD, and project design 

  • Develop and implement a CX plan

  • Develop a system test procedure 

Correct answer: Develop the OPR and BOD 

The OPR, or Owner's Project Requirements document, is developed by the owner. This document is then used by the team to develop the Basis Of Design (BOD). The commissioning authority is not responsible for completing either of these documents. 

The commissioning authority is responsible for reviewing the OPR, BOD, and project design as well as for developing and implementing a CX plan and developing a system test procedure.

85.

Which of the following is not an alternative to potable water?

  • Black water

  • Gray water

  • Rainwater

  • Municipally supplied reclaimed water

Correct answer: Black water

Black water, which is water that has come in contact with human waste, cannot be reused unless it is extensively treated. 

Alternatives to potable water include municipally supplied reclaimed water, gray water, rainwater, treated seawater, stormwater, and used process water. 

86.

What is required for spaces with hazardous gases or chemicals in IEQ Credit–Enhanced Indoor Air Quality Strategies?

  • Negative pressure 

  • A minimum MERV filter rating of 13 or higher 

  • Natural ventilation

  • An acceptable entryway system 

Correct answer: Negative pressure 

IEQ Credit–Enhanced Indoor Air Quality Strategies requires spaces that contain hazardous gases or chemicals to create negative pressure by having a minimum exhaust rate of 0.50 cfm per square foot (2.54 l/s per square meter). 

Natural ventilation and entryway systems are not required. A minimum MERV filter rating of 13 or higher is an option for the entire building to comply with this credit's requirements, not just for certain areas. 

87.

What does the IP ANSI Consensus National Standard Guide provide?

  • Step-by-step guidance and a methodology for improving building design, construction, and operations through a replicable, integrative process

  • Information about efficient water strategies

  • Requirements for sustainable building design through the use of the integrative process 

  • Methods for discovering potential sustainable project sites

Correct answer: Step-by-step guidance and a methodology for improving building design, construction, and operations through a replicable, integrative process

LEED recommends that project teams review the IP ANSI Consensus National Standard Guide as it provides step-by-step guidance and a methodology for improving building design, construction, and operations through a replicable, integrative process. This is especially important for projects hoping to achieve IP Credit–Integrative Process. 

This guide does not provide information about water efficiency, choosing a project site, or the requirements of sustainable buildings. 

88.

Which particulate removal systems are considered acceptable entryway systems according to IEQ Credit–Enhanced Indoor Air Quality Strategies? 

  • Permanently installed grates, grilles, slotted systems, rollout mats

  • Rubberized temporary mats

  • Hanging fabric barriers

  • Revolving doorways 

Correct answer: Permanently installed grates, grilles, slotted systems, rollout mats

IEQ Credit–Enhanced Indoor Air Quality Strategies requires acceptable entryway systems including permanently installed grates, grilles, slotted systems, and rollout mats or another system that is equally efficient or better.

Temporary systems do not qualify; they must be permanent. Hanging barriers do not qualify because they are not effective.  Revolving doors are not entryway systems. 

89.

To earn points in Option 3. Measurement of EQ Credit–Daylight, project teams must achieve illuminance levels between 300 lux and 3,000 lux. Achieving acceptable levels for what percentage of floor area can earn a project team two points for this credit option? 

  • 75%

  • 90%

  • 65%

  • 100%

Correct answer: 75%

Option 3 of EQ Credit–Daylight requires project teams to achieve illuminance levels between 300 lux and 3,000 lux. Achieving acceptable levels for 75% of the regularly occupied floor area can earn projects two points. 

Achieving acceptable levels for 90% of the regularly occupied floor area can earn projects three points. Achieving acceptable levels for 65% of the floor area is insufficient, and doing so for 100% would earn the project three points. 

90.

Which type of Environmental Product Declaration (EPD) is valued as one whole product for Option 1 of MR Credit–Building Product Disclosure and Optimization–Environmental Product Declarations?

  • Product-specific Type III EPD 

  • Industry-wide (generic) EPD 

  • Industry-wide Type III EPD 

  • Product-specific Type II EPD 

Correct answer: Product-specific Type III EPD 

Product-specific Type III EPDs are valued as one whole product in calculations for this credit. 

Industry-wide (generic) EPD products are valued as half of a product. An industry-wide Type III EPD doesn't exist. Product-specific Type II EPDs do not meet the requirements for this credit. 

91.

To earn exemplary performance in EQ Credit–Quality Views, project teams must meet the requirements of the credit for what percentage of all regularly occupied areas? 

  • 90% 

  • 75%

  • 85% 

  • 100% 

Correct answer: 90% 

To earn exemplary performance in EQ Credit–Quality Views, project teams must meet the requirements of the credit for 90% of all regularly occupied areas. 

To earn EQ Credit–Quality Views, 75% of the building's regularly occupied floor area must have a direct line of sight to the outdoors using vision glazing. Meeting this requirement for 85% of the floor area will earn the credit but not exemplary performance. Meeting the requirement for 100% would earn exemplary credit but is not necessary. 

92.

How do high-quality indoor environments benefit building owners?

  • Enhance productivity, decrease absenteeism, improve the building’s value, and reduce liability

  • Intensify stress, encourage circuitous navigation, elevate wear and tear, and amplify maintenance costs

  • Increase the aesthetics of the building, decrease boredom, improve the building's value, reduce liability 

  • Increase the quality of light and acoustics in the building to make the environment more pleasant 

Correct answer: Enhance productivity, decrease absenteeism, improve the building’s value, and reduce liability

The benefits of high-quality indoor environments are not as obvious as reducing energy or water usage, but they make a big difference to owners and tenants of a building. They enhance productivity, decrease absenteeism, improve the building’s value, and reduce liability. 

A high-quality interior does not intensify stress, encourage circuitous navigation, elevate wear and tear, amplify maintenance costs, or decrease boredom. Increasing the quality of light and improving acoustics in the interior are strategies to raise the quality of the interior. 

93.

At what height should the calculation grids for sDA and ASE be laid out across the regularly occupied area for EA Credit–Daylight, Option 1?

  • 30 inches (76 millimeters) above the finished floor

  • 35 inches (89 millimeters) above the finished floor

  • 20 inches (51 millimeters) above the finished floor

  • 25 inches (64 millimeters) above the finished floor

Correct answer: 30 inches (76 millimeters) above the finished floor

EQ Credit– Daylight, Option 1, requires project teams to demonstrate that they have achieved acceptable Spatial Daylight Autonomy (sDA) and Annual Sunlight Exposure (ASE). To calculate these figures, the sDA and ASE calculation grids should be no more than 2 feet (600 millimeters) square and have a height of 30 inches (76 millimeters) above the finished floor. 

Other than for extenuating circumstances, the height of the measurements may not be any more or less than 30 inches (76 millimeters) above the finished floor. 

94.

What must a project team do to achieve exemplary performance in Option 1 of MR Credit–Building Product Disclosure and Optimization–Sourcing of Raw Materials?

  • Source at least 40 products from five manufacturers 

  • Source at least 20 products from five manufacturers 

  • Source at least 30 products from six manufacturers 

  • Source at least 80 products from ten manufacturers 

Correct answer: Source at least 40 products from five manufacturers 

Project teams can achieve exemplary performance in Option 1 of MR Credit–Building Product Disclosure and Optimization–Sourcing of Raw Materials by sourcing at least 40 different products from five manufacturers. 

Sourcing at least 20 products from five manufacturers is the minimum for the credit. Sourcing at least 30 products from six manufacturers would earn the credit but not exemplary performance. Sourcing at least 80 products from ten manufacturers would earn exemplary performance but is not required. 

95.

What is the maximum allowed percentage of structure and enclosure materials in compliant building products that may be used in calculations for MR Credit–Building Product Disclosure and Optimization–Environmental Product Declarations?

  • 30% 

  • 50%

  • 100%

  • 200%

Correct answer: 30% 

Option 2 of MR Credit–Building Product Disclosure and Optimization–Environmental Product Declarations does not allow more than 30% of the structure and enclosure materials to be used in calculations. 

Third-party certified products that have impact reduction below the industry average in at least three of the impact categories are valued at 100% of their cost for this credit. Option 2 of the credit requires project teams to use products that comply with one of two options for 50% by cost of the total value of the permanently installed products. Products that are sourced within 100 miles of the project site are valued at 200% of their cost. 

96.

Defining an appropriate LEED boundary is an element in which of the following requirements? 

  •  MPRs 

  • LEED prerequisites 

  • CIRs 

  • LEED credits 

Correct answer: MPRs

The Minimum Program Requirements (MPRs) must be met for a project to qualify for LEED certification. These requirements include defining an appropriate LEED boundary, being a permanent fixture of the land, and complying with the size requirement of the desired LEED rating system.

LEED credits are not required. Prerequisites are required, but defining an appropriate LEED boundary is not one of the prerequisites. Credit Information Requests (CIRs) are not a set of requirements; they are a tool to help teams when they struggle to understand how to fulfill a credit or prerequisite. 

97.

Which of the following credits aims to discourage project teams from developing on inappropriate sites? 

  • LT Credit–LEED for Neighborhood Development Location 

  • IP Credit–Integrative Process

  • RP Credit–Regional Priority

  • WE Credit–Indoor Water Use Reduction

Correct answer: LT Credit–LEED for Neighborhood Development Location 

The intent of LT Credit–LEED for Neighborhood Development Location is to dissuade project teams from developing on inappropriate sites, reduce the distance of occupants' commutes, enhance livability, and improve human health by providing a walkable environment. 

IP Credit–Integrative Process encourages project teams to work in collaboration and perform initial analysis. RP Credit–Regional Priority encourages projects to prioritize the credits that are most impactful to the needs of the project's local environment. WE Credit–Indoor Water Use Reduction encourages project teams to reduce their indoor water use from the baseline. 

98.

A project that will hold over 65% of computer equipment, mostly storage systems for the company, wants to become LEED Certified. Which of the following rating systems would be best for this project? 

  • LEED ID+C: Commercial Interiors

  • LEED ID+C: Data Centers

  • LEED ID+C: Retail

  • LEED ID+C: Warehouses and Distribution Centers 

Correct answer: LEED ID+C: Commercial Interiors

Because this project is neither a hospitality nor a retail project, its only option in the ID+C rating system is ID+C: Commercial Interiors. 

LEED ID+C: Data Centers and LEED ID+C: Warehouses and Distribution Centers do not exist. Since this is not a retail project, it cannot use LEED ID+C: Retail. 

99.

What item of documentation is required only for projects using Compliance Path 2 of WE Prerequisite–Indoor Water Use Reduction? 

  •  Indoor water use calculator 

  • Product cutsheets, manufacturers' information 

  • Alternative water source calculations 

  • Plumbing system design drawings 

Correct answer: Indoor water use calculator 

The second compliance path is Usage-Based Calculation, and it requires project teams to use LEED's indoor water use calculator to calculate water use.

Product cutsheets and manufacturers' information are the documentation required for WE Prerequisite–Indoor Water Use Reduction, regardless of the path chosen. Alternative water source calculations and plumbing system design drawings are documentation required for WE Credit–Indoor Water Use Reduction. 

100.

What prerequisite or credit's purpose is to reduce stratospheric ozone depletion? 

  • EA Prerequisite–Fundamental Refrigerant Management 

  • There is no credit or prerequisite with this aim 

  • EA Credit–Enhanced Commissioning

  • EA Credit–Renewable Energy Production 

Correct answer: EA Prerequisite–Fundamental Refrigerant Management 

CFC-based refrigerants cause stratospheric ozone depletion. To reduce this depletion, LEED required projects to stop using CFC-based refrigerants. 

EA Credit–Enhanced Commissioning aims to further support the design, construction, and efficient operation of the project. EA Credit–Renewable Energy Production aims to encourage projects to use renewable energy rather than fossil fuels.
