USGBC Updated LEED-AP-BD+C Exam Questions and Answers by ayaz

For schools intended for grades eight and below (or ages 14 and below), Option 2. Pedestrian Access requires that at least 50% of the students live no more than a 3/4 mi. (1.20 km) walking distance from a functional entry of a school building. This option aims to encourage schools to locate in areas where students can walk or bike to school, reducing vehicle trips and emissions, and promoting physical activity and health. Option 2 is available only for projects that do not meet the requirements of Option 1. Transit-Served Location, which requires access to quality transit service within a 1/4 mi. (400 m) walking distance for at least 50% of the students. References :

Showers are addressed under Water Efficiency (WE) Prerequisite: Indoor Water Use Reduction and Location and Transportation (LT) Credit: Bicycle Facilities . Showers in indoor water use reduction help minimize potable water consumption, while in the Bicycle Facilities credit, they support cycling commuters by providing end-of-trip facilities. The other options refer to credits or prerequisites unrelated to shower facilities.

According to the LEED V5 : Building Design + Construction Guide, the Location and Transportation Credit, Bicycle Facilities has two options: Option 1. Bicycle Network and Storage and Option 2. Reduced Parking Footprint. Option 1 requires the project to provide short-term bicycle storage for at least 2.5% of all peak visitors, and long-term bicycle storage for at least 5% of all regular building occupants. Short-term bicycle storage must be within 100 ft (30 m) walking distance of any main entrance, and long-term bicycle storage must be within 300 ft (90 m) walking or bicycling distance of any functional entry. Option 2 requires the project to provide short-term bicycle storage for at least 2.5% of all peak visitors, and long-term bicycle storage for at least 5% of all regular building occupants, and also reduce the total parking capacity by at least 20% from the base ratios. Both options can earn one point under this credit 1 .

If a commercial building is considered to have 100 peak visitors in a day, the minimum number of short-term bicycle storage spaces that must be provided to earn one point under Option 1 or Option 2 is 2.5% of 100, which is 2.5, rounded up to 3. However, the project must also provide long-term bicycle storage for at least 5% of all regular building occupants, which is not given in the question. Therefore, the correct answer is C, five, which is the minimum number of short-term bicycle storage spaces that must be provided to earn one point under Option 1 or Option 2, regardless of the number of regular building occupants.

The scope of analysis in Materials and Resources Credit, Building Life-Cycle Impact Reduction, Option 4. Whole-Building Life-Cycle Assessment is a cradle-to-grave assessment. This means that the life cycle assessment (LCA) covers all stages of the building’s life cycle, from the extraction of raw materials (cradle) to the disposal or reuse of the building components at the end of their service life (grave) 1 . The LCA must include the following life cycle stages: product stage, construction process stage, use stage, and end-of-life stage 2 . The LCA must also account for the environmental impacts of the building’s structure and enclosure, as well as any other building elements that are permanently attached to and share service systems with the building 2 .
