Someone Open to a Variety of Green Options
The gold standard in green construction is the LEED certification. The Leadership in Energy and Environmental Design certification is one which ensures that your building fits very strict standards in terms of sustainability and energy conservation. Your green contractor should know, at the very least, the ins and outs of the LEED system, and he should be able to fit his construction to the standards set forth by the LEED commission [source: U.S Green Building Council]. If following the LEED program seems either impossible or impractical, then your contractor should be able to provide you with some viable and comparable options to make sure that you're getting the best in sustainable building.
