Hello. i have a doubt about this credit.
We're working on a Children's Museum. One of the first decissions to make it more sustainable is to make all the museum underground, having the insulation of earth and opening it to a inner court to get light.
We have a reduced thermal load with this strategy.
When we're modelling the energy, the Modeler asked us it this stretegy could be modeled. So the Baseline should be in the same Geometry, but overground, and in de Design case is underground.
Since the Appendix G mentions that the geometry of the Envelope should be the same.

I think it will be very disspointing if this decission, which is major part of the design, and that will cost the client a lot, and it supplies a good thermal output, couldn't be modeled and rewarded by LEED points.

Could you please make some comment about that? How can I model this strategy?

Thanks in advance!!!
