My project is not located in the U.S. Should I still use the emissions factors from the Energy Star program listed in the Reference Guide, or find something closer to home?

International projects can calculate emissions through the World Resource Institute’s Greenhouse Gas Protocol tools.

The LEED Reference Guide says we need to account for seasonal variations in commuting behavior. What should I do?

Submitted by on

The geographic location of your project will likely determine how this will be addressed. Consider how the weather influences commuter choices in your area, and how you can modify your survey timing or strategy accordingly. For example, if you have plenty of parking capacity, occupants may switch their commuting mode per weather conditions or season. A few ideas to consider include: 

Do we have to collect home zip code data in our survey?

Submitted by on

Gathering zip code information is optional. It’s a useful data point for organizations that are thinking of implementing more ambitious or targeted transportation planning for employees. Zip code data would allow an organization to identify demand for targeted programs addressing geographic areas that are underserved by existing alternative transportation options.

What if we already participate in a local transportation survey? Can we use those results?

Submitted by on

The LEED Reference Guide states: “Projects that participate in a local or regional program can use the raw data from those survey results and complete the credit calculations to determine the alternative transportation rate; no additional survey is required. The raw data from a local or regional program can be used only if they are specific to the project building and the results are collected during the performance period.”
