How many different permanently installed products should be used to earn MR Credit–Building Product Disclosure and Optimization–Environmental Product Declarations?

  • At least 20 different permanently installed products

  • At least 15 different permanently installed products

  • At least 25 different permanently installed products

  • At least 10 different permanently installed products

Correct answer: At least 20 different permanently installed products

Option 1 of MR Credit–Building Product Disclosure and Optimization–Environmental Product Declarations asks project teams to use at least 20 different permanently installed products sourced from at least five different manufacturers that meet one of three criteria. 

Only 10 or 15 products would not meet the minimum requirements. While 25 products would exceed the minimum requirements, it is not required to have 25 products to earn points in this credit. 

42.

What is excluded from the calculation for Option 1: Interior Reuse of MR Credit–Interiors Life-Cycle Impact Reduction? 

  • Hazardous materials

  • Metal materials 

  • Wood materials 

  • Glass materials 

Correct answer: Hazardous materials

Option 1: Interior Reuse of MR Credit–Interiors Life-Cycle Impact Reduction requires project teams to reuse or salvage materials for at least 50% of the surface area. When calculating this percentage, projects must exclude hazardous materials. 

Metal, wood, and glass materials are not hazardous, so they are not excluded. 

43.

In material ingredient optimization, product ingredients assessed with the full GreenScreen Assessment are valued at what percentage? 

  • 150%

  • 50%

  • 100%

  • 200%

Correct answer: 150%

In material ingredient optimization, any ingredients assessed with the full GreenScreen Assessment are valued at 150% of the cost for MR Credit–Building Product Disclosure and Optimization Material Ingredients. 

44.

What is the minimum requirement for Spatial Daylight Autonomy (sDA) to earn three points in EQ Credit–Daylight?

  • 75%

  • 60%

  • 55%

  • 90%

Correct answer: 75% 

EQ Credit–Daylight, Option 1, requires that project teams demonstrate that they have achieved an sDA of at least 55% for two points or 75% for three points. 

An sDA of 90% would earn the project three points, but this is not the minimum. An sDA of 60% would earn the project two points. 

45.

According to EQ Prerequisite–Minimum Indoor Air Quality Performance, what standard should project teams use to determine the minimum outdoor air intake flow for mechanically ventilated spaces?

  • ASHRAE 62.1–2010

  • ASHRAE 90.1–2010

  • ANSI/BIFMA e3-2011

  • ISO 14044

Correct answer: ASHRAE 62.1–2010

To comply with EQ Prerequisite–Minimum Indoor Air Quality Performance, mechanically ventilated spaces must meet the requirements set out in ASHRAE Standard 62.1–2010. 

ASHRAE 90.1–2010 is the standard for energy efficiency. ISO 14044 is used in MR Credit–Building Life-Cycle Impact Reduction. ANSI/BIFMA e3-2011 is the standard used in EQ Credit–Low-Emitting Materials.

46.

What is the maximum percentage of the value of compliant building products that structure and enclosure materials may constitute?

  • 30% 

  • 50%

  • 40%

  • 20%

Correct answer: 30%

Option 2 of MR Credit–Building Product Disclosure and Optimization–Sourcing of Raw Materials states that no more than 30% of the structure and enclosure materials may be included in the value of compliant building products. 

Values of 20% and 40% don't feature in this credit option. Products meeting extended producer responsibility criteria are valued at 50% of their cost. 

47.

What percentage of the total connected lighting load should have a rated life of at least 24,000 hours in EQ Credit–Interior Lighting, Option 2?

  • 75%

  • 95%

  • 85%

  • 65%

Correct answer: 75%

EQ Credit–Interior Lighting, Option 2, requires projects to choose four of the acceptable strategies. One of the strategies is to ensure that at least 75% of the total connected lighting load has a rated life of at least 24,000 hours. 

Meeting this requirement for 95% or 85% of the load would be acceptable, but neither of these is the minimum. Meeting the requirement for 65% of the load is not acceptable for this strategy. 

48.

What is the purpose of defining a reasonable LEED boundary?

  • To ensure accurate evaluation of the project

  • To give the project an advantage

  • To evaluate buildings and spaces

  • To allow project teams to exclude portions of the building 

Correct answer: To ensure an accurate evaluation of the project

To meet the MPRs, project teams must use a reasonable LEED boundary to define their project boundary. This requirement aims to ensure that the project is evaluated accurately and to prevent project teams from excluding portions of the building that may not qualify for LEED.

This will not give the project an advantage or disadvantage; it will just ensure an accurate evaluation. 

The MPRs come before the evaluation of the building/spaces. 

49.

EQ Credit–Daylight, Option 2: Simulation, requires project teams to demonstrate that the illuminance levels in their building are or will be between 300 lux and 3,000 lux for what time frame? 

  • 9 a.m. and 3 p.m.

  • 6 a.m. and 12 p.m.

  • 3 a.m. and 9 p.m.

  • 12 p.m. and 6 p.m.

Correct answer: 9 a.m. and 3 p.m.

EQ Credit–Daylight, Option 2: Simulation, requires project teams to demonstrate that the illuminance levels in their building are or will be between 300 lux and 3,000 lux for 9 a.m. and 3 p.m. 

50.

What is the recommended area-weighted average surface reflectance for walls in EQ Credit–Interior Lighting, Option 2?

  • 60%

  • 25%

  • 85%

  • 90%

Correct answer: 60%

EQ Credit–Interior Lighting, Option 2, requires projects to choose four of the acceptable strategies. One of the strategies is for project teams to meet or exceed the recommended threshold of 60% area-weighted average surface reflectance for walls for at least 90% of the regularly occupied floor area. 

Doing so for less than 90% of regularly occupied floor area is not enough for this strategy. The strategy for ceilings requires an area-weighted average surface reflectance of 85%. The area-weighted average surface reflectance required for floors is 25%. 

51.

 Which of the following credit categories offers four potential points? 

  • Regional Priority 

  • Innovation

  • Sustainable Sites

  • Integrative Process

Correct answer: Regional Priority 

The Regional Priority credit category offers up to four points to projects that achieve credits corresponding to local environmental concerns. 

Innovation offers a total of six possible points, Sustainable Sites offers a total of ten possible points, and Integrative Process offers a total of two possible points. 

52.

For which of the following would a project team be using ASHRAE Standard 55–2010 as guidance? 

  • Thermal Comfort Conditions for Human Occupancy

  • Designing a natural ventilation system 

  • Creating a construction air quality management plan 

  • Performing a flush-out before occupancy

Correct answer: Thermal Comfort Conditions for Human Occupancy

EQ Credit–Thermal Comfort, Option 1, requires project teams to design heating, ventilation, and HVAC systems to meet ASHRAE Standard 55–2010. 

The design of a natural ventilation system should follow the Chartered Institution of Building Services Engineers (CIBSE) Applications Manual AM10. Performing a flush-out before occupancy does not require a project team to follow one specific standard. Creation of a construction air quality management plan should conform to Sheet Metal and Air Conditioning National Contractors Association (SMACNA) IAQ Guidelines for Occupied Buildings under Construction.

53.

Once the water budget analysis is complete and the results have been documented, what should the team's next step be? 

  • Show how at least one on-site, nonpotable water supply was used to reduce the demand on the municipal water supply

  • The team has completed the requirements for this part of the credit, and nothing more needs to be done

  • Take samples for a simple water quality test

  • Install submeters

Correct answer: Show how at least one on-site, nonpotable water supply was used to reduce the demand on the municipal water supply

The team has not yet completed all the steps to this part of the credit. Having completed water budget analysis and documented the resulting effects on the building design, the team should next show how one or more on-site, nonpotable water supplies reduced the demand for municipal water. Submeters and water samples are not required for this credit. 

54.

When can waste-to-energy systems be considered waste diversion for MR Credit–Construction and Demolition Waste Management?

  • When a project cannot meet credit requirements using reuse and recycling methods

  • When a project is trying to achieve Option 1: Diversion

  • When a project is trying to achieve Option 2: Reduction of Total Waste Material 

  • When an international project is trying to earn MR Credit–Construction and Demolition Waste Management 

Correct answer: When a project cannot meet credit requirements using reuse and recycling methods

If a project cannot meet the requirements of MR Credit–Construction and Demolition Waste Management through reuse and recycling methods, waste-to-energy systems may be considered waste diversion. 

The project team's choice of credit options does not affect whether waste-to-energy systems can be considered diversion, nor does whether a project is international. 

55.

Projects can earn two points in EQ Credit–Daylight, Option 2: Simulation, by demonstrating that illuminance levels meet the requirements for what percentage of regularly occupied floor area? 

  • 90%

  • 75%

  • 55%

  • 60% 

Correct answer: 90% 

EQ Credit–Daylight, Option 2: Simulation, requires project teams to demonstrate that the illuminance levels in their building are or will be between 300 lux and 3,000 lux for 9 a.m. and 3 p.m. Projects that demonstrate that illuminance levels meet these requirements for 90% of regularly occupied floor area earn two points. 

Projects that demonstrate that illuminance levels meet these requirements for 75% of regularly occupied floor area earn one point. Meeting the requirements for 55% or 60% of floor area is not high enough to earn points in this credit option.  

56.

Wood products must be certified by what organization to be included in calculations for Option 2 of MR Credit–Building Product Disclosure and Optimization–Sourcing of Raw Materials? 

  • Forest Stewardship Council 

  • Sustainable Agriculture Network

  • Global Reporting Initiative 

  • Organisation for Economic Co-operation and Development 

Correct answer: Forest Stewardship Council 

Option 2 of MR Credit–Building Product Disclosure and Optimization–Sourcing of Raw Materials requires all wood products to be certified by the Forest Stewardship Council or a USGBC-approved equivalent to be included in the calculation for this credit. 

The Sustainable Agriculture Network sets the standard that all bio-based materials must meet for Option 2 of this credit. The Global Reporting Initiative and the Organisation for Economic Co-operation and Development provide CSR frameworks that are acceptable to use for Option 1 of this credit. 

57.

Which of the following is the minimum Cradle to Cradle certification level that a product needs to be considered for MR Credit–Building Product Disclosure and Optimization– Material Ingredients?

  • v2 Basic

  • v2 Gold 

  • v3 Silver

  • v3 Platinum 

Correct answer: v2 Basic

Cradle to Cradle products must be at least v2 Basic level or v3 Bronze level to qualify for Option 1 of this credit. 

While v2 Gold, v3 Silver, and v3 Platinum are excellent choices, a product is not required to have earned these to meet the minimum requirements of this credit. 

58.

How many different permanently installed products are required for raw material source and extraction reporting?

  • At least 20

  • At least 15

  • At least 25

  • At least 10

Correct answer: At least 20

MR Credit–Building Product Disclosure and Optimization–Sourcing of Raw Materials, Option 1, requires project teams to use at least 20 different permanently installed products from at least five different manufacturers that have publicly available reports on their raw material suppliers. 

Using 25 different products would be an excellent achievement but is not required to earn points. Using 15 or 10 products would not be enough to meet the minimum requirements for this credit option.  

59.

What is the minimum requirement for a project to qualify for LEED for Interior Design and Construction?

  • At least 60% of the project's gross floor area must be complete

  • At least 60% of the project's gross floor area must be incomplete

  • At least 40% of the project's gross floor area must be complete

  • More than 40% of the project's gross floor area must be incomplete

Correct answer: At least 60% of the project's gross floor area must be complete

To qualify for any of the rating systems within ID+C, a project must have its gross floor area at least 60% complete by the time of certification. 

BD+C: Core and Shell projects must be more than 40% incomplete by the time of certification. 

60.

What is an example of a programmatic solution for reducing plug and process loads? 

  • Implementing equipment and purchasing policies

  • Replacing exterior materials

  • Upgrading HVAC systems

  • Increasing insulation levels

Correct answer: Implementing equipment and purchasing policies

Projects can reduce plug and process loads through equipment and purchasing policies or layout options.

Replacing exterior materials, upgrading HVAC systems, and increasing insulation levels would not help with reducing the plug and process loads because these systems are not considered plug and process loads.
