    A new office project will have 200 employees and anticipates an estimated 30 visitors / day. During peak periods, the building will be occupied by 210 occupants. The project team is trying to achieve SS Credit 4.2 Alternative Transportation: Bicycle Storage & Changing Rooms.  How many secure bicycle storage spaces will be required? 

    • A.

      2

    • B.

      10

    • C.

      11

    • D.

      12

    • E.

      21

    Correct Answer
    C. 11
    Explanation
    The number of secure bicycle storage spaces required can be calculated by taking into account the number of employees, visitors, and peak occupancy. Since the project will have 200 employees, it is reasonable to assume that at least some of them will use bicycles. Additionally, with an estimated 30 visitors per day, it is possible that some of them may also use bicycles. Therefore, the total number of potential bicycle users can be calculated as 200 employees + 30 visitors = 230 potential bicycle users. Considering that the building will be occupied by 210 occupants during peak periods, it is safe to assume that not all potential bicycle users will be present at the same time. Therefore, it is reasonable to provide secure bicycle storage spaces for at least 11 bicycles to accommodate the potential demand.
