The LEED v4.1 O+M Beta Guide includes a table with the CO2e value for each mode of transit (in pounds/mile). The Arc platform will automatically apply the appropriate CO2e value to the survey responses.

The available transportation survey responses on Arc include: walk, bike, telecommute, motorcycle or scooter, light rail (trolley, tram, or streetcar), rapid transit (subway/metro), carpool (two to three people), alternative fuel vehicle, bus, and car (solo). We recommend reaching out to Arc/GBCI to determine how to account for other transit modes.

The survey must be conducted at least once per year.

The survey must be distributed to regular building occupants. Examples are employees, volunteers who regularly use the building, residents (including residents of a dormitory), primary and secondary school students, hotel guests, and inpatients. Visitors are encouraged to be surveyed, especially if the daily average is greater than the number of regular building occupants. Examples of visitors are retail customers, outpatients, volunteers, and higher-education students. See page 20 of the LEED v4.1 O+M Beta Guide for additional information on occupancy types.

According to the Data Management Guide for Buildings, the minimum response rate is typically 25% but could be less for high-occupancy buildings. The Arc platform will determine the minimum response rate needed to generate a score for your project, based on your occupancy inputs.

No, the transportation survey must be completed on the Arc platform.

The LEED v4.1 O+M Beta Guide states that survey must be completed in the Arc platform. Data from surveys conducted outside of the platform are not accepted at this time. However, you can opt to do a “lobby survey,” which will activate the survey for “in person” administration on a single device or multiple devices. This mode enables teams to collect survey responses from a lobby location.
