<DIV> Hi, <BR>very simple question im sure, but im new to ESP-r,
<BR>modelling an industrial units energy consumption.<BR><BR>Is it possible to
have a child surface in a zone which is just an open hole,<BR>such as a vent
hole? i have tried using the "ficticious" material, <BR>but it seems to make no
difference to the heat lossed from the building.<BR><BR>Thanks for any help,
