QUESTION: 77

Which of the following project team members should be integrated early into the design phase to assist with earning the Materials and Resources Prerequisite, Construction and Demolition Waste Management Planning?

Owner
Contractor
Occupants
Facility manager

Answer(s): B

Explanation:

. Contractor
The contractor is the project team member who should be integrated early into the design phase to assist with earning the Materials and Resources Prerequisite, Construction and Demolition Waste Management Planning. The contractor is responsible for implementing the waste management plan, which includes estimating the types and quantities of waste materials, identifying the diversion strategies, selecting the waste haulers and recyclers, tracking and documenting the waste diversion performance, and training the subcontractors and workers. The contractor can provide valuable input on how to reduce, reuse, and recycle the construction and demolition waste, as well as identify potential challenges and opportunities for achieving the prerequisite requirements.

QUESTION: 78

The Sustainable Sites Credit, Heat Island Reduction takes into account both new and three-year aged Solar Reflectance Index (SRI) values for roofing material because

SRI generally increases with age
SRI generally decreases with age
SRI generally remains the same with age
SRI generally does not impact the Heat Island Effect

Answer(s): B

Explanation:

. SRI generally decreases with age

The Solar Reflectance Index (SRI) is a measure of the ability of a surface to reflect solar heat, as shown by a small temperature rise. It is calculated using the values of solar reflectance and thermal emittance of the surface. The higher the SRI, the lower the heat island effect. However, SRI generally decreases with age due to factors such as weathering, dirt accumulation, and biological growth. Therefore, the Sustainable Sites Credit, Heat Island Reduction takes into account both new and three- year aged SRI values for roofing material to ensure that the material maintains a high level of reflectance over time.

QUESTION: 79

Which of the following statements is correct when defining the project boundary?

The LEED project boundary cannot include non-contiguous land
The LEED project boundary cannot include more than one building
The land associated with the project supports typical operation
The gross floor area of the LEED project should be no less than 1% of the gross land area within the LEED project boundary

Answer(s): C

Explanation:

. The land associated with the project supports typical operations According to the LEED v4 Reference Guide for Building Design and Construction, the LEED project boundary must include all contiguous land that is associated with the project and supports its typical operations. This includes land altered as a result of construction and features used primarily by the project's occupants, such as hardscape (parking and sidewalks), septic or stormwater treatment equipment, and landscaping. Therefore, statement C is correct when defining the project boundary. Statement A is incorrect because the LEED project boundary must be contiguous. Statement B is incorrect because the LEED project boundary can include more than one building, as long as they are on the same site and share a common scope of work. Statement D is incorrect because there is no such requirement for the gross floor area of the LEED project to be a certain percentage of the gross land area within the LEED project boundary.

QUESTION: 80

A project's massing and site orientation can have a direct impact on which of the following prerequisites?

Minimum Energy Performance
Minimum Indoor Air Quality Performance
Construction Activity Pollution Prevention
Fundamental Commissioning and Verification

Answer(s): A

Explanation:

. Minimum Energy Performance
A project's massing and site orientation can have a direct impact on the minimum energy performance prerequisite, which requires projects to demonstrate a percentage of energy cost savings compared to a baseline building. Massing and orientation affect the amount of solar heat gain, daylight availability, natural ventilation potential, and wind exposure of the building, which in turn influence the heating, cooling, lighting, and ventilation loads and strategies. By optimizing the massing and orientation of the building, projects can reduce their energy consumption and improve their thermal and visual comfort.
