<DIV><FONT face=Arial size=2><SPAN class=593553613-14092009>I am working on a
LEED job comparing a 2FDD system to a VAVRH system using A90 Appendix G. The
humidification load on the 2FDD uses the room total cfm for sizing where the
VAVRH uses the minimum OA for sizing. 200,000 cfm verses 50,000 cfm. The 2FDD
humidification load is nearly four times the VAVRH. Per Trace Help both
humidification coils are at the same location as the cooling
coil.</SPAN></FONT></DIV>
