A Healthcare Project is constructing a new building adjacent to an existing LEED Certified hospital facility. The new building's location is on the same hospital campus as the certified facility. The entire hospital campus was analyzed with an Environmental Site Assessment (ESA) as part of the certified facility's project scope. The new building project needs to complete a new Phase I ESA if
Answer(s): D
. the local equivalent standard is more stringent than ASTM E1527-05 According to the LEED v4 Reference Guide for Building Design and Construction, a Phase I ESA is required for all projects, except for those located on previously developed land that has not been used for industrial, commercial, or agricultural purposes. The Phase I ESA must follow the ASTM E1527-05 standard or a local equivalent. However, if the local equivalent is more stringent than the ASTM standard, then the project must comply with the local equivalent. Therefore, if the new building project is located in a jurisdiction that has a more rigorous standard for Phase I ESA than ASTM E1527-05, then it must complete a new Phase I ESA, regardless of the previous ESA done for the certified facility.

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?
Answer(s): B
. ContractorThe 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.

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 decreases with ageThe 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.

Which of the following statements is correct when defining the project boundary?
Answer(s): C
. 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.

A project's massing and site orientation can have a direct impact on which of the following prerequisites?
Answer(s): A
. Minimum Energy PerformanceA 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.
