[EnergyPlus_Support] purchased air

[teklay Weldeabzgi <teklay1979@xxxxxxxxx>]

 i am trying to see the annual cooling load reduction
using roof and wall insulation. my model is purchased
air model. and when i see the results from the
simulation; with insulation in roofs the sensible
cooling energy reduces while the latent heat gain
increase. this result is seen in the reports Purchased
Air Sensible Cooling Energy[J]and Purchased Air Total
Cooling Energy[J]. the result shows the saving from
Purchased Air Sensible Cooling Energy[J] is greater
than the saving from Purchased Air Total Cooling
Energy[J]in using insulation. but i can't understand
why insulation increases the latent load. is there any
reason for this.
