International Project - Case 2 Option 1 or Option 2

A couple of thoughts on your situation. Based on your description, I would think that the entire building would be classified as a "retail-mall" as the equivalent to Portfolio Manager's enclosed mall space type. Per the Portfolio Manager glossary, the floor area associated with the mall should include Gross Floor Area should include all space within the building(s), including retail stores, offices, food courts, restaurants, storage areas, staff break rooms, atriums, walkways, stairwells, and mechanical rooms. Given that I don't think you should break out spaces unless they are distinct from a typical mall space. With respect to the alternative source EUI, that is only relevant if your team intends to use an alternative baseline that aligns with your project location. If not, you can use the default baseline EUI. With respect to Option 2c, I think you could potentially pursue that path if you can make the case that the default EUI for a retail-mall is not an appropriate benchmark for your facility. But, I would suggest making this case to GBCI via LEED Interpretation prior to submitting the project for review.
