FAQs about MRc1.1 :

What building elements get included in this calculation and what can be excluded?

Should I base my calculations on plan or elevation?

How do you calculate the existing building structure reuse?

How do exterior elements, such as a covered dock, get counted? Would that be considered a slab or exterior hardscape and not part of the building?

Is a large curtain wall to be considered as exterior wall or glazing for this credit? Thank You!

Sara, See response to Janice above. Additionally, if your project in question is a full curtain wall glazed facade, I believe you can qualify this material as exterior envelop. As long as you remain consistent in your approach, you should be able to comply as either windows or envelop. Lastly, I'm curious if the existing curtain wall was to be maintained, how the building would meet energy minimums - but that's another story and different LEED credit! :-)
