Dear All, I am modeling (in eQUEST) a simple building with a multi-zone layout. Some zones are mechanically cooled while few zones are naturally ventilated and I am looking forward for a LEED submission. I could model the proposed building for energy performance (Appendix G) including naturally ventilated zones. In modeling the baseline case HVAC system, irrespective of type of cooling (i.e. mechanical cooling or natural ventilated), I have selected the HVAC system as per the Appendix G. Can anybody throw some light on the use of same baseline HVAC system for naturally ventilated occupied zones as well and acceptability of the same to LEED reviewing. Thanks in advance Anura
