From a preliminary review, we received a comment regarding the Energy Modeling saying that the slab on grade floor of the proposed should be modeled using a F-factor, and not using the U-value as it was done. This is the first time we get this comment, even though in all previous certifications we always model the slab on grade floor of the proposed design using the U-value. For the baseline design we do use the F-factor. Any suggestions or ideas on how to reply to this?
Thanks in advance
