Tyler Thumma 7Group LEEDuser Expert 67 thumbs up February 21, 2025- 11:31 am 1. This issue would require troubleshooting of the modeling inputs which it outside the scope of this forum. I recommend contacting the software support team if you are unable to resolve this. 2. The Baseline system is determined using Table G3.1.1-3 based on building type/size and climate zone, with additional modifications for dehumidification as outlined by Section G3.1.3.18.  Log in or register to post comments Anurag Ghosh LEEDuser Basic Member February 22, 2025- 8:45 am Hi Tyler, I would like to reclarify whether such reheat coils...
