style='font-size:11.0pt;color:#1F497D'>Depending on your internal gains, the
increased levels of roofing insulation may make it more difficult for the
system to reject the heat. I generally find this response when modeling
auditoriums or rooms with high levels of internal gains. The system ends up
working overtime to displace the heat that would normally have escaped after
the internal loads subsided and/or ambient conditions cooled off. For instance,
on a 45 degree day, the building might break even with a high internal gain and
low roof insulation, but with the higher roof insulation, the internal gains
dominate and cooling is required. It really depends on the scenario, but
without more information, I can only say that it’s plausible. <o:p></o:p></span></font></p>
