101.

By how much should aggregate water consumption be reduced from the baseline?

  • 20%

  • 50%

  • 30%

  • 10%

Correct answer: 20%

WE Prerequisite–Indoor Water Use Reduction requires projects to reduce aggregate water consumption by 20% from the baseline. 

Reductions of 50% and 30% are acceptable but are not the minimum percentage required by the prerequisite. A reduction of 10% would not be acceptable. 

102.

What must be on newly installed aerators or flow restrictors added to private lavatories or showers?

  • WaterSense label

  • Energy Star certified 

  • USDA Organic 

  • Cradle to Cradle 

Correct answer: WaterSense label

WE Prerequisite–Indoor Water Use Reduction requires all newly installed fixtures and fixture fittings to be WaterSense labeled. This includes aerators and flow restrictors. 

Aerators and flow restrictors do not qualify for Energy Star certification or USDA Organic certification. Cradle to Cradle certification would not have an impact on the product's water efficiency. 

103.

Which products should be selected for all new fixtures within the project according to WE Prerequisite–Indoor Water Use Reduction?

  • WaterSense labeled products

  • Products made with recycled materials 

  • Energy Star products 

  • Products that exceed the baseline water use 

Correct answer: WaterSense labeled products

LEED recommends the use of WaterSense labeled (or local equivalent) fixtures and fixture fittings because these products ensure water efficiency and performance.

Energy Star products are not the focus of this prerequisite, but projects may install certain products, such as washing machines and dishwashers, that are Energy Star certified to help the project achieve greater energy and water efficiency. Products made with recycled materials are covered in the Materials and Resources credit category. 

104.

For how long are projects required to share their meter data with the USGBC?

  • Five years 

  • Four years 

  • Three years 

  • One year

Correct answer: Five years

Option 1 of EA Credit–Advanced Energy Metering requires project teams to install new or use existing tenant-level energy meters as well as commit to sharing their meter data with the USGBC for a five-year period. 

Sharing data for less than five years would not meet the requirements set out in this option of the credit. 

105.

In which of the following projects would an alternative gender ratio be more appropriate than the default gender ratio?  

  • A women's university that has a few male teachers and staff

  • A male-dominated Art Department building at a coed university

  • A government building

  • An office building of a women-owned company

Correct answer: A women's university that has a few male teachers and staff

Single-gender educational facilities are eligible to use an alternative gender ratio for full-time-equivalent occupants. 

Buildings that are dominated by one gender but are not single-gender facilities are not considered special circumstances. These buildings' imbalanced gender ratio is not a permanent status. Government buildings, coed schools, and office buildings should use the default gender ratio. 

106.

A team is starting a new construction project and is having a hard time choosing a rating system. The project's gross floor area is 38% retail and 62% office space. Which of the following rating systems should they use? 

  • ID+C: Commercial Interiors 

  • ID+C: Retail

  • ID+C: Office 

  • ID+C: Hospitality 

Correct answer: ID+C: Commercial Interiors 

Because the project is a new construction project and the retail space makes up only 38% of the gross floor area while 62% is office space, LEED ID+C: Commercial Interiors is the best choice. 

Not enough of the gross floor area is retail for the project to use ID+C: Retail as the rating system. ID+C: Office does not exist. None of the project's gross floor area consists of hospitality, so it should not use ID+C: Hospitality. 

107.

Project teams must reduce their baseline water use by at least what percentage to earn WE Prerequisite–Indoor Water Use Reduction? 

  • 20%

  • 15%

  • 10% 

  • 30% 

Correct answer: 20% 

Project teams must reduce their indoor water use by 20% from the baseline to earn this credit. All newly installed water fixtures must be WaterSense labeled. 

The BD+C WE Prerequisite–Outdoor Water Use Reduction requires a 30% reduction, but ID+C does not have this prerequisite. A reduction of 10% or 15% is not enough to earn WE Prerequisite–Indoor Water Use Reduction. 

108.

To meet the requirements of Option 1 of EA Credit–Enhanced Refrigerant Management, what is the allowed Ozone Depletion Potential (ODP) for refrigerants? 

  • 0

  • 7

  • 50

  • 30

Correct answer: 0 

Option 1 of EA Credit–Enhanced Refrigerant Management requires any refrigerants used in the project to have an ozone depletion potential of 0. 

ODPs greater than zero do not meet the requirements of Option 1 of this credit. 

109.

Which organization's standard must bio-based products meet to comply with MR Credit–Building Product Disclosure and Optimization–Sourcing of Raw Materials?

  • Sustainable Agriculture Network

  • Forest Stewardship Council 

  • UN Global Compact

  • Global Reporting Initiative Sustainability Report 

Correct answer: Sustainable Agriculture Network 

Option 2 of MR Credit–Building Product Disclosure and Optimization–Sourcing of Raw Materials requires all bio-based products to comply with the Sustainable Agriculture Network's Sustainable Agriculture Standard. 

Wood products must be certified by the Forest Stewardship Council. The UN Global Compact and the Global Reporting Initiative Sustainability Report are corporate sustainability report frameworks used in Option 1 of this credit. 

110.

A project team wants to leave their interior 50% incomplete so that renters can change the design to suit their purposes. Which of the following is true? 

  • This project does not qualify for ID+C rating systems

  • This project must use ID+C: Core and Shell 

  • This project should use ID+C: Commercial Interiors 

  • This project can use any ID+C rating system except ID+C: Hospitality, which requires interiors to be completed by the time of certification

Correct answer: This project does not qualify for ID+C rating systems

ID+C projects must have at least 60% of their interiors completed by the time of certification. Since this project plans on leaving 50% of its interior incomplete, it does not qualify. 

There is no such rating system as ID+C: Core and Shell. The project can't use ID+C: Commercial Interiors or any other ID+C rating system because, to be able to use ID+C rating systems, the project's interiors must be at least 60% completed by the time of certification. ID+C: Hospitality does not require projects to be fully completed by the time of certification; they have to be at least 60% completed, however. 

111.

A project team can ensure that a percentage of the nonstructural materials used in the building are reusable or recyclable. What percentage would make the team eligible to earn MR Credit–Interiors Life-Cycle Impact Reduction? 

  • 50%

  • 75% 

  • 40% 

  • 25% 

Correct answer: 50% 

To be eligible for Option 3 of MR Credit–Interiors Life-Cycle Impact Reduction, the project team must ensure that 50% of the nonstructural materials by cost used in the building are reusable or recyclable.

Ensuring 75% of materials are reusable or recyclable is an excellent accomplishment but is not required to earn points for this credit. On the other hand, 40% and 25% do not meet the minimum requirement. 

112.

 Which of the following is this team aiming to achieve if they are working to reduce their water use by 20% from the baseline?

  • WE Prerequisite–Indoor Water Use Reduction 

  • WE Credit–Indoor Water Use Reduction 

  • WE Credit–Outdoor Water Use Reduction 

  • WE Prerequisite–Outdoor Water Use Reduction 

Correct answer: WE Prerequisite–Indoor Water Use Reduction 

To achieve WE Prerequisite–Indoor Water Use Reduction, project teams must reduce their indoor water use by at least 20%. 

ID+C does not cover outdoor water use. WE Credit–Indoor Water Use Reduction requires lowering indoor water use from the baseline; the minimum reduction is 25% for one point. 

113.

What is the purpose of reducing plug and process loads?

  • To lower energy consumption

  • To increase occupant comfort

  • To improve indoor air quality

  • To maximize daylighting

Correct answer: To lower energy consumption

Plug and process loads include computers, printers, shredders, and anything else that can be plugged in that is included in the everyday use of the space. Reducing these loads can significantly reduce energy consumption. 

Reducing plug and process loads would not affect the indoor air quality, occupant comfort, or amount of daylight. 

114.

What is not considered construction, demolition, or renovation waste according to MR Prerequisite–Construction and Demolition Waste Management Planning?

  • Land-clearing debris

  • Concrete scraps

  • Timber

  • Metal reinforcements

Correct answer: Land-clearing debris

Land-clearing debris and ADC (Alternative Daily Cover) do not qualify as construction waste diverted from the landfill for this prerequisite. 

Concrete scraps, timber, and metal reinforcements are acceptable construction or renovation waste. 

115.

According to MR Credit–Construction and Demolition Waste Management, what is excluded from calculations when recycling and salvaging construction and demolition materials?

  • Excavated soil and land-clearing debris

  • Wood waste converted to fuel

  • Alternative daily cover

  • Nonhazardous demolition materials 

Correct answer: Excavated soil and land-clearing debris

Excavated soil and land-clearing debris must be excluded from calculations for MR Credit–Construction and Demolition Waste Management.

Wood waste converted to fuel, alternative daily cover, and nonhazardous demolition materials should be included in the calculations. 

116.

Project teams who plan to operate permanently installed air-handling equipment during construction must use a filtration system with at least what MERV rating? 

  • 8

  • 7

  • 13

  • 10

Correct answer: 8

Air hanging systems that are being used during construction must have a MERV rating of at least 8 or a class of F5 or higher according to EQ Credit–Construction Indoor Air Quality Management Plan. 

A MERV rating of 7 is too low to meet the minimum requirements. A MERV rating of 10 or 13 would meet this requirement but is not the minimum. 

117.

To earn a project one point in Option 2: Diverse Uses of LT Credit–Surrounding Density and Diverse Uses, a project's main entrance must be within a 1/2-mile walking distance from how many diverse uses? 

  • Four to seven

  • Eight to ten

  • Three to six

  • Six to eight

Correct answer: Four to seven

For the second option of LT Credit–Surrounding Density and Diverse Uses, the project’s main entrance must be within a 1/2-mile walking distance of four to seven diverse uses to earn one point and within a 1/2-mile walking distance of eight or more diverse uses to earn two points. 

There is no cap on the number of diverse uses a project team can be near; any number above seven will earn a project team two points. Three diverse uses won't earn a project team any points.

118.

What should be conducted for retail projects for MR Prerequisite–Storage and Collection of Recyclables? 

  • Waste stream study

  • Air quality assessment 

  • Construction and demolition waste audit 

  • Water budget analysis 

Correct answer: Waste stream study

Retail projects are required to perform a waste stream study to identify their top five recyclable waste streams. 

An air quality assessment is performed in the Environmental Quality credit category. A construction and demolition audit is not required, but a construction waste management plan is. A water budget analysis should have been performed early in the project for the Integrative Process credit category. 

119.

Under what circumstances can an alternative gender ratio be justified?

  • Projects specifically designed for an alternative gender ratio

  • Projects with a larger population

  • Projects with a smaller population

  • Projects with no designated gender areas

Correct answer: Projects specifically designed for an alternative gender ratio

Projects that are specifically designed for an alternative gender ratio may use a gender ratio that suits the project. For example, a women's college will need a gender ratio that reflects the higher number of women than men.

Projects' populations have no impact on the required gender ratio. Projects with no designated gender areas should use the default gender ratio.

120.

How much of a parking reduction from its base ratios does a project need to achieve to earn one point if it has earned LT Credit–Surrounding Density and Diverse Uses or LT Credit–Access to Quality Transit?

  • 40%

  • 20%

  • 30%

  • 10%

Correct answer: 40% 

Projects that are able to earn either LT Credit–Surrounding Density and Diverse Uses or LT Credit–Access to Quality Transit should not need as much parking as other projects. Therefore, the percentage of parking reduction they must achieve is higher. These projects need to achieve a 40% reduction to earn one point and a 60% reduction to earn two points.

A 20% parking reduction is the requirement for projects that have not achieved either LT Credit–Surrounding Density and Diverse Uses or LT Credit–Access to Quality Transit. Reductions of 30% and 10% are not high enough for projects that have achieved either of these credits.
