LEED-AP-BD+C Exam Dumps - LEED AP Building Design + Construction (LEED AP BD+C)

According to the LEED Reference Guide for Building Design and Construction1, the Location and Transportation Credit, Bicycle Facilities, requires the project to provide short-term and long-term bicycle storage and a functional entry or bicycle storage within 200 yards of a bicycle network. The bicycle network is defined as any one of the following:

Off-street bicycle paths or on-street bicycle lanes that are physically marked and separated from motor traffic

Streets designed for a target speed of 25 mph (40 km/h) or less, with traffic calming features such as curb extensions, speed humps, raised crossings, narrowed traffic lanes, median islands, tight corner radii, roundabouts, or landscaping

Streets with a legal speed limit of 25 mph (40 km/h) or less that connect to a larger bicycle network

Therefore, among the given options, only slow speed roadways can define a bicycle network, as they can provide a safer and more comfortable environment for cyclists. One-way streets, bike share, and traffic lights are not sufficient to define a bicycle network, as they do not necessarily indicate the presence of bicycle paths, lanes, or low-speed streets.

Reducing the area planned for surface parking and replacing it with additional vegetated space can provide several benefits to the owner, such as:

Decreasing the amount of bicycle parking that must be provided, since there will be less demand for parking spaces for cyclists.

Increasing the overall SR (solar reflectance) of the hardscape area, which can reduce the cooling load and energy consumption of the building.

Decreasing the required amount of on-street parking that must be provided, since there will be less demand for parking spaces for cars.

However, one of the most significant benefits of this strategy is increasing the rainwater infiltration capacity, which can improve the water quality and quantity in the stormwater system. According to a study by Biondolilo1, integrating green space into parking lots can decrease stormwater runoff, mitigate the heat island effect, store carbon, improve air quality and may have social benefits as well. The study estimated that converting 30% of Manhattan’s parking into green space would decrease runoff and pollutants from parking lots1. Therefore, this strategy can help reduce water demand and environmental impact in arid climates.

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.

ASHRAE 62.1-2010 is the standard that an engineer should use when establishing minimum ventilation rates for a new mechanically ventilated space to earn Indoor Environmental Quality, Minimum Indoor Air Quality Performance. This is the standard referenced by the LEED v4 BD+C Reference Guide for this prerequisite. Local building code, International Mechanical Code 2012, and the ventilation code requiring the greatest volume of outside air are not acceptable alternatives for this prerequisite.References: LEED v4 BD+C Reference Guide, Indoor Environmental Quality Category, EQp Minimum Indoor Air Quality Performance, page 674.

The minimum scope of analysis for a product-specific declaration is cradle-to-gate, which means from raw material extraction to the factory gate. This option requires the use of at least 20 different permanently installed products sourced from at least five different manufacturers that have product-specific declarations.

The percentage of recycled content contributing to the credit is calculated based on the value of the recycled content relative to the total construction cost. The combined value of recycled content here is $1 million (post-consumer) + $1 million (pre-consumer) = $2 million. The percentage is then calculated as:

2,000,00010,000,000×100=20%\frac{2,000,000}{10,000,000} \times 100 = 20\%10,000,0002,000,000​×100=20%

Therefore, the recycled content accounts for 20% of the total material value for the project, contributing to the Materials and Resources Credit: Building Product Disclosure and Optimization - Sourcing of Raw Materials.

According to the LEED AP BD+C V4 reference guide for Healthcare, places of respite must be outdoors or located in interior spaces with views of nature, and have options for shade or indirect sun for a portion of seating spaces. The other options are either incorrect or not required by the credit. References: LEED AP BD+C V4 reference guide for Healthcare, Places of respite

The correct sequence for LEED certification is: Choose Rating System, Register, Submit documentation through LEED Online, Review, Certify (C). Projects begin by selecting the appropriate LEED rating system, then register with USGBC, followed by documentation submission for review. After review, certification is granted based on achieved points. This structured approach ensures accurate and consistent compliance with LEED standards.
