They always see much much higher than predicted/designed infiltration and higher energy cost/comfort issues but not always significantly (5% is significant to me but not to all) higher cost in heavy cooling areas due to what seems to be both the infiltration that occurs when the conditioned air is cooler/less humid on the interior and the comparatively low cost to cool. <o:p></o:p></span></font></div><div style="margin-top: 0in; margin-right: 0in; margin-left: 0in; margin-bottom: 0.0001pt; font-size: 11pt; font-family: Calibri; "><font size="2" color="navy" face="Arial"><span style="font-size: 10pt; font-family: Arial; color: navy; "><o:p> </o:p></span></font></div><div style="margin-top: 0in; margin-right: 0in; margin-left: 0in; margin-bottom: 0.0001pt; font-size: 11pt; font-family: Calibri; "><font size="2" color="navy" face="Arial"><span style="font-size: 10pt; font-family: Arial; color: navy; ">We have very limited experience in industrial but in office, commercial, retail, and similar have seen from James numbers (his range is mostly the low end we have seen) to 5 times them and even more. The numbers tend to go completely crazy when we have tried to look at real world effects and apply parameters such as actual in use conditions for office, commercial or retail buildings. We have never seen an existing building that was at the ‘design parameters’. I am not saying that as a negative toward anyone who did or does design nor about the assumptions in the models but am saying that it needs to be looked at as we need to end up saving most of our energy, carbon, cost, whatever all you care about through work on existing structures.
