Sustainable transportation rate = the total percentage of occupants who traveled to the project by Equation 1. Calculating the sustainable transportation rate

Equation 1. Calculating the sustainable transportation rate

• Walked

• Cycled

the following active and shared modes of transportation:

• Took public transportation (e.g., bus, streetcar, subway, railroad, ferryboat)

• Carpooled/vanpooled (i.e., car, truck, or van with two or more people in the vehicle)

• Worked at home (telecommuted)

The transportation mode choices presented in the survey may be modified to reflect local options, provided all options are mapped to the list of modes above in the survey results.

OR

Option 2. Location Efficiency Score (1–6 points)

Demonstrate that the project location meets a location-efficiency score via Walk Score®. Points are awarded according to Table 2.

Table 2. Points for location efficiency

Walk Score®	Points
50–59	1
60–69	2
70–79	3
80–84	4
85–89	5
90–94	6

REQUIREMENTS EXPLAINED

For newly constructed buildings, project teams can consider how a chosen location may affect travel patterns for building occupants and the surrounding community. Although existing buildings don’t have this same opportunity, there are still important ways a project team can assess and enhance sustainable transportation performance for occupants. Project teams may wish to understand their occupants’ travel behaviors so they can improve them.

The Transportation Survey provides an opportunity to evaluate the Sustainable Transportation Rate (STR) of travel behavior. The STR survey focuses on modes of transportation rather than greenhouse gas emissions, simplifying calculations while emphasizing low-carbon travel modes.
