Concrete SR Test Didn't Pass

Hi Mike, Let me ask a few seemingly obvious questions to make sure you've already covered the basics. I'm guessing you already use the actual credit form to plug in the roof and site reflectance info/SF, and any qualifying shaded areas to see how you fared, and were not able to meet the thresholds needed? The weighted aspect of the calcs can skew some project's results to where they still meet the requirements, though individual areas don't comply with the minimums as written in the Guide. Since you mentioned you have such a large paving area, sounds like it just overpowers the other compliant areas contributing to the calcs. v4 projects are allowed to use the standard reflectance values like in the past, but it hasn't been confirmed for sure for v4.1. Is your project fully registered under 4.1 and therefore must use this version, or has someone chosen to use the 4.1 update instead of the v4 one (for a v4-registered project)? 
If fully v4.1, have you emailed LEEDCoach to see if they can confirm if past LEED Interpretations can still apply? If the above aspects have been exhausted, the only other thing on my radar is potentially applying a higher reflectivity concrete coating to enough area to comply. I have not personally had this on a project, but I know the products exist and should have several manufacturers as options, depending on what the area is being used for, and probably project location may play into product selection, too.

I would definitely email LEED Coach and ask for guidance on being able to use the previous rulings and default reflectance values on a 4.1 effort, too, before moving to anything else.

I totally agree with Emily's comments. The LEEDonline form layout can be a little confusing when it comes to determining if a project has met the weighted calculation. When you look at "Summary of Heat Island Reduction Measures Table: Summary of nonroof and roof" as long as the value under "Weighted sum of nonroof and roof measures" in the "Total Weighted Area" column is greater than the value under "Sum of project paving and roof area" in the "Total Standard Area" column you have met the credit requirement.
