Dears, In our recent projects we are having some doubts about the “Building Footprint” definition.

The Project is composed of 2 separate buildings connected together with 2 floors of underground garage and 8 floors of skyway.

I´m working in a Project in Buenos Aires, Argentina, that is trying to achieve SSc5.1.

My C&S project has a terrace on the 1st floor (below there is only the parking garage). That terrace is only accessible by the Meeting Room, which is used by the building users.

Would a reclaimed land qualify as a Greenfield Site and can a project on such site earn SSc5.1 under case 1?

If there are city/state/federal restrictions on development such that development in certain areas is prohibited by law, can I include those areas in the LEED project boundary?

We are working on a winery project with an above ground winery building and connected underground wine storage caves.

I've heard recently that Sedum roofs are no longer being accepted as providing enough habitat to achieve 5.1. Is there any truth to this?

In our Project we have an underground floor with retail program that has a larger projection that the ground floor which is also retail.
