Dear all,
We have a retail mall in Malaysia targeting LEED EBOM v2009 rating. Under the portfolio manager our mall would fall under the "enclosed mall" space type, which is not eligible for the energy star certification or scoring and thus would lead us to the Case 2 offline calculator for this credit.
Under the Case 2 calculator, we've created a breakdown of all space types within the mall which pointed us to use Case 2 Option 1.
The baseline developed on there for the National Average Source EUI, is 315kBtu/sqft. However, the table does ask that international project insert an "Alternative Source EUI", which we assume would be the Malaysian national source EUI. But there is no such data available unfortunately.
As such, we were wondering if we could opt to develop our baseline using Option 2C instead which is our historic building data + comparable buildings?
Any guidance on this is much appreciated!

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.
