I’m modeling the indoor temperatures during a heat wave for an old two-story apartment building in Los Angeles (passive design), and I’m having some issue trying to simulate an 18" crawlspace condition below a wood frame floor assembly.
I’ve tried modeling the crawlspace as its own separate room; however, the indoor temperatures of the Level 1 apartment unit don’t seem to be picking up any heat transfer from the crawlspace area below. Is there a better way to model a crawlspace ground condition? Has anyone had any luck trying to build a custom assembly that mimics a crawlspace?
Thank you.
