Inquiry
Is a model required to use the prescriptive Tables 5.5-1 to 5.5-8 for the existing envelope thermal parameters for all spaces converted from unconditioned to conditioned, or in the baseline model, could you use the existing thermal parameters regardless of changes in space conditioning as per Appendix G Table3 G3.1.5 and LEED Reference Guide for Green Building Design and Construction?
Ruling
Section G3.1.5 assumes that the space type classification for the space has not changed. If the applicant is changing an unconditioned space to a conditioned space, the applicant must model a minimally compliant envelope as per tables 5.5-1 to 5.5-8 in the baseline models.
