Intent

To reduce pollution and land development impacts from automobile use for commuting.

Requirements

Reduce the number of commuting round trips made by regular building occupants using single occupant, conventionally powered and conventionally fueled vehicles. For the purposes of this credit, alternative transportation includes at a minimum, telecommuting; compressed workweeks; mass transit; rideshare options1; human-powered conveyances; carpools; vanpools; and low-emitting, fuel-efficient2 or alternative-fuel vehicles; walking or bicycling.

Performance calculations are made relative to a baseline case that assumes all regular occupants commute alone in conventional automobiles. The calculations must account for seasonal variations in the use of alternative commuting methods and, where possible, indicate the distribution of commuting trips using each type of alternative transportation.

Points are earned for reductions in conventional commuting trips during the performance period according to the following schedule:

Demonstrated percentage reduction in
conventional commuting trips
Points
10% 3
13.75% 4
17.50% 5
21.25% 6
25.00% 7
31.25% 8
37.50% 9
43.75% 10
50.00% 11
56.25% 12
62.50% 13
68.75% 14

1 Rideshare is a transit service that involves sharing a single vehicle with multiple people, excluding large-scale vehicles such as buses and trains. The rideshare transit facility must include a signed stop and a clearly defined waiting area. Additionally, the rideshare must include an enclosed passenger seating area, fixed route service, fixed fare structure, continuous daily operation, and the ability to pick up and drop off multiple riders.
2 Low-emitting vehicles and fuel-efficient vehicles are defined as vehicles that are classified as zero-emission vehicles (ZEVs) by the California Air Resources Board or that have achieved a minimum green score of 40 on the American Council for an Energy Efficient Economy annual vehicle-rating guide.

What does it cost?

Cost estimates for this credit

On each BD+C v4 credit, LEEDuser offers the wisdom of a team of architects, engineers, cost estimators, and LEED experts with hundreds of LEED projects between then. They analyzed the sustainable design strategies associated with each LEED credit, but also to assign actual costs to those strategies.

Our tab contains overall cost guidance, notes on what “soft costs” to expect, and a strategy-by-strategy breakdown of what to consider and what it might cost, in percentage premiums, actual costs, or both.

This information is also available in a full PDF download in The Cost of LEED v4 report.

Frequently asked questions

The LEEDuser survey template asks for the occupant’s home zipcode. Some of our occupants won’t want to provide this sort of personal information. Do we have to collect this data?

The answer to this question is available to LEEDuser premium members. Start a free trial »

(If you're already a premium member, log in here.)

The LEED Reference Guide says that the survey should not be announced in a way that might generate skewed responses or encourage unrepresentative behavior. We’ve been educating our occupants for several months on the LEED process. What should we do?

The answer to this question is available to LEEDuser premium members. Start a free trial »

(If you're already a premium member, log in here.)

The LEED Reference Guide says that survey results can be extrapolated to all nonrespondents if the survey response rate is 80%, but I also saw this was true for a 60% response rate. Which is correct?
