Which of the following is an example of a nonroof measure for Sustainable Sites Credit, Heat Island Reduction?
Correct Answer: B
Explanation A vegetated shading structure is an example of a nonroof measure for Sustainable Sites Credit, Heat Island Reduction. The heat island effect is the phenomenon of urban areas having higher air temperatures than surrounding rural areas due to the absorption and emission of heat by human-made surfaces, such as buildings, roads, and pavements. The heat island effect can have negative impacts on the environment, human health, and energy consumption. One of the strategies to reduce the heat island effect is to use nonroof measures that provide shade, reflectivity, or evapotranspiration for at least 50% of the site hardscape, such as parking lots, walkways, plazas, and courtyards1. A vegetated shading structure is a type of nonroof measure that consists of a trellis or pergola that supports climbing plants or vines that provide shade and cooling for the underlying surface. A vegetated shading structure can also enhance the aesthetic and ecological value of the site2. The other options are not examples of nonroof measures for Sustainable Sites Credit, Heat Island Reduction. A playground with artificial turf is not a nonroof measure, but a roof measure, as it is considered as part of the building envelope. Artificial turf is also not a compliant roof measure, as it does not meet the minimum solar reflectance index (SRI) or vegetated roof requirements1. A shade structure with a three-year aged SRI value of 0.2 is not a compliant nonroof measure, as it does not meet the minimum SRI value of 29 for nonroof surfaces1. A paving material with a three-year aged SRI value of 0.2 is also not a compliant nonroof measure, as it does not meet the minimum SRI value of 29 for nonroof surfaces1.

Question 72
What are the Storage and Collection of Recyclables requirements for only Retail projects under the Materials and Resources Prerequisite?
Correct Answer: A
Retail projects must conduct a waste stream audit for the duration of the project in an existing location or make projections based on historical data for similar establishments. Identify the top-five recyclable waste streams while stating the top-four waste streams where both collection and storage space will be provided. This is the requirement for Retail projects under the Materials and Resources Prerequisite, Storage and Collection of Recyclables, according to the LEED v4 BD+C Reference Guide1. The purpose of this prerequisite is to facilitate the reduction of waste generated by building occupants that is hauled to and disposed of in landfills1. The prerequisite applies to all LEED BD+C projects, but Retail projects have a different approach than other project types because of their unique waste streams and operational characteristics1. Retail projects must conduct a waste stream audit for the duration of the project in an existing location or make projections based on historical data for similar establishments. The audit or projection must identify the top-five recyclable waste streams by weight or volume using consistent metrics throughout1. The waste stream study period must be a minimum of 24 hours1. Retail projects must also provide dedicated areas that serve the entire building and are accessible to waste haulers and building occupants for the collection and storage of materials for recycling for at least four of the top-five recyclable waste streams identified by the audit or projection1.

Question 73
For a bicycle network to demonstrate compliance with Location and Transportation Credit, Bicycle Facilities, the bicycle network must connect to
Correct Answer: D
According to theLEED V5: Building Design + Construction Guide, the bicycle network must connect to a rapid transit stop that is within 3 mi. (5 km) biking distance of the project boundary. This is one of the options to meet the requirement for Option 1: Bicycle Network and Storage. The other options are to connect to at least 10 diverse uses or to connect to a school or employment center that is within 3 mi. (5 km) biking distance of the project boundary.

Question 74
A commercial new construction project consists of mixed space usage. When deciding which LEED rating system to use, the LEED AP should follow which of the following rules?
Correct Answer: D
According to theLEED V5: Building Design + Construction Guide, the 40/60 rule provides guidance for making a decision when several rating systems appear to be appropriate for a project. To use this rule, first assign a rating system to each square foot or square meter of the building, and then choose the most appropriate rating system based on the resulting percentages. The entire gross floor area of a LEED project must be certified under a single rating system and is subject to all prerequisites and attempted credits in that rating system, regardless of mixed construction or space usage type. If a rating system is appropriate for less than 40% of the gross floor area of a LEED project building or space, then that rating system should not be used. If a rating system is appropriate for more than 60% of the gross floor area of a LEED project building or space, then that rating system should be used.If an appropriate rating system falls between 40% and 60% of the gross floor area, project teams mustindependently assess their situation and decide which rating system is most applicable1.Reference:LEED V5: Building Design + Construction Guide, LEED Rating System Selection Guidance1
Question 75
A school wants to incorporate natural daylighting in classrooms on all sides of the building. What can the project design team explain to the school district about how this strategy will affect the operational energy cost?
Correct Answer: B
Natural daylighting can reduce the electricity use for artificial lighting, which is one of the major components of operational energy cost for buildings. By having the lights off or dimmed when sufficient daylight is available, the project can save energy and money. The other options are not necessarily true or relevant for natural daylighting. Heat gain and passive solar heating depend on the orientation, shading, and insulation of the windows, not just the amount of daylight.Reduction in lighting fixture use may reduce re-lamping, but that is not a significant factor in operational energy cost compared to electricity use.Reference: EA Credit Optimize Energy Performance, EQ Credit Daylight,LEED V5Reference Guide for Building Design and Construction123
