With all due respect it sounds I think you have this backwards.  I'm assuming you don't have much knowledge or experience in green build so as a LEED GA and Architect-in-Training let me try and share my knowledg.  Please don't hesitate to let me know if you have any questions.

Builders don't profit off of long-term ROI, they would likely lose money or possibly break even. Most builders sell the property off either to individuals or to another owner who rents it out thus  the theory, mostly of the left, is that builders don't care about "life-cycle cost" they only care about up front cost which would mean things like green roofs and solar panels don't get built.  I think that shows a nieve lack of understanding as any competent buyer would study the O&M (Operations and Maintenance) costs and take those life-cycle costs into account which would of course influence their offer price to purchase the property so that builders, in fact, do have an incentive to do things like green roofs.
