Has anyone used Grasshopper for energy simulation and successfully submitted for LEED certification?

I have not personally seen any Grasshopper energy models submitted for LEED. It is unclear whether it meets the simulation program requirements of Section G2.2.

FAQs about EAp2:

Do the required savings for this prerequisite (and credit) need to come only from building energy, or also process loads?

Our project doesn't have enough energy savings to earn the prerequisite. Can we get there by incorporating onsite renewables?

Our proposed design has insulation R-values that are below those prescribed by ASHRAE 90.1-2010. Can we still meet the prerequisite?
