SSc4: Alternative Commuting Transportation, focuses on documenting your building occupants’ use of alternative transportation modes for commuting to and from the project building. Option 3 allows you to comply with the credit requirements by conducting a survey of your regular building occupants’ commuting behavior over a five-day period. In practice, the majority of project teams who attempt this credit do so with the commuter survey.
It is important to make sure that your survey adheres to SCAQMD Rule 2202 procedures, a set of guidelines that helps you to properly structure your survey and ensure that the results capture an accurate assessment of occupant commuting behavior.
The following strategy will review best practices for developing, distributing, and conducting your commuting survey. You may also refer to the sample survey language in the SSc4 Documentation Toolkit to review a completed example.
We are working on a project that is a university Residence Hall on campus. I have found it difficult to find information on how to design a survey for alternative commuting for residential structures. I realize this is a unique situation, but we are interested in earning points for this credit. Any suggestions?
Erin - That's a question I would definitely recommend taking to GBCI in some form or fashion. I have heard rumblings from GBCI that they are not comfortable with residence halls assuming a baseline of 100% conventional vehicle use from which to assess reductions. There are differing opinions on how on-campus residence halls should be treated in SSc4; one school of thought is that by being on campus they effectively reduce commuting trips to zero (or near-zero) and are thus the height of good urban planning. The other school of thought is that we should be comparing dorms to dorms, not dorms to office buildings, and therefore use a different methodology to assign points. As far as I know, there is not yet anything public or firm on this debate - perhaps you can make your voice heard on the matter.
Thank you Dan. We are going to contact GBCI on the matter. I will be happy to share any information they provide.
Our building has a fair amount of telecommuters and employees who are on alternative work schedules (usually, every other Friday off). How do we capture those in the survey if they're not at work?!
Can you reach those folks with an email or online survey? Capturing telecommuters with an 'elevator survey' is a real challenge - if that is a substantial portion of your building population, another survey method might be a better bet. Folks on alternative schedules can be most easily reached by surveying on a Monday (and asking about behavior from the previous week), which is not perfect but certainly not a dealbreaker.
Hope this helps,
Thanks - took me awhile to get back here.
One building's survey pool size was determined to be ~500 out of ~1500 total occupants. Assume survey forms are to delivered to every third person passing into the elevator vestibules (the only ingress). This is the only means of ingress to tenant areas and the point where the tenant flow into the building has become homogenous, regardless of their mode of transportation (note that stairways are locked in the direction of ingress causing all occupants to pass through the lobbies). Is this a sufficiently random sample? How does one account for those telecommuting or otherwise not traveling to work under this scenario?
It is a viable strategy James - GBCI has approved the 'elevator survey' in this context and it works very nicely. One thing to be sure of is that you spread your survey out over an extended time period - even if you reach 500 respondents by 8am, the demographics of people arriving later could differ substantially from those arriving earlier (in a building I recently surveyed, financial folks all arrived before 7am, legal folks largely afterward - their survey responses weren't radically different, but they were noticeably so.)
The one down-side to the elevator survey is that you miss out on telecommuters. Just no good way to catch that in the survey tool.
Hope that helps a bit
