Hello everyone. I'm now working on a project under certification, according to LEED v2009 NC. The project includes the restoration of an historical rural building, uninhabited and abandoned from lo

I have a large building with an arena at the second level. I am retaining the slab on grade on the first level except for some small cuts to run piping.

Our project is a major renovation to a historic building, and preliminary calcs are showing that we are reusing 99.1% of existing walls/floors/roof.

With regard to Credit MRc1.1-Exisitng walls, floors and roof: I have a building which has a fake mansard around its perimeter.

Hi, We are designing a 36,000sf addition to a 55,000sf school. This school addition will be an extension of the existing school buildings wing.

I'm working on behalf of a GC on a complicated historic renovation and new construction project that's being done in several phases with separate contracts between Owner and GC.

We have basement level rooms that extend beyond the above-grade building footprint. Effectively, the terrace serves as the roof for these below-grade rooms.

My building has several windows that are less than 10 years old. They are in excellent shape.

Would a curtain wall be considered exterior wall or glazing for this credit? Thanks!
