Assuming it's new construction, of course.

Ramana,

Per Table G3.1 section 5b, the baseline is always a steel-framed wall for Appendix G modeling. So you get to take credit for additional thermal mass.

Dear all,

For a LEED EAp2/EAc1 energy model, does the following above-grade wall situation fall under a mass wall or a steel-framed wall in the baseline?

8" CMU wall (load bearing) with steel studs to the interior just to create a cavity for the batt insulation etc.

Thanks,
Ramana Koti.
