Green Codes

As far as a green building goes, once the developer/client has agreed to a certain goal (LEED level or other standard), the responsibility lies in the hands of the GC for all aspects of the "construction submission" (as opposed to the "design submission" obviously in the hands of the arch & engineer). GC is in the perfect position to educate (from 1 on 1 discussion to regular meetings) and enforce (hold payments) the subs on these standards.]

I'd also like to add another note, which I hope people can respond to or comment on. In terms of planning and more specifically in terms of changing codes, I am presuming that new standards are never arbitrary, but based on the observation of prior accomplishments. For example, Bloomberg wouldn't have mandated some of his initiatives such as local law 86 (http://www.nyc.gov/html/dob/downloads/pdf/ll_86of2005.pdf) if i wasn't for so many completed LEED projects in NYC and in other cities. So then it's developers like Durst (Conde Naste bldg, 1 Bryant Park, Helena....) who can provide a template once again for raising the bar even further.

So here is the question I pose: Do progressive developers drive the movement for which the code then adopts, or should the code lead the way and force the developers to adapt?
