I would expect that the temperatures would not be exactly the same as my Corridor since they are not being directly controlled but I am surprised to see such low temperatures as 30F and am sure the spaces will not reach these temperatures in real world conditions. I am looking for some guidance on how to best model this scenario. Any help would be appreciated.<o:p></o:p></p></div><div><p class=MsoNormal>Thank you,<o:p></o:p></p></div><p class=MsoNormal><o:p> </o:p></p></div></div></body></html>
