I am working on a project that is approx. 24,600sf which includes 11,600s.f. of major renovation with 13,000s.f new construction. We are using Option 1 Whole Building Simulation.
How do I select the threshold for the project from Table 1 in Reference Guide? Is it "New Construction" column since 53% of the project is new construction? Or Major Renovation?? Major Renovation column gives project more points? Prorated? That would complicate the heck out of energy modeling process!!!
For example:
24% New Construction = 10 points
24% Major Renovation = 11 points
Looking for feedback from fellow LEEDUsers that have already crossed this bridge with Reviewers.

When you have a combination of new and existing the thresholds for points are determined by a weighted average calculation. For example, one point is earned at 6% savings for new and 4% existing. If the new is 50% of the total the adjusted threshold would be 5%. You then go up in the same 2% increment for additional points. So in your case the threshold for the first point is 5.06% (2% x 0.53) + 4%.
