High Latent Loads

Question

Hello, 
 I am working on a open plant office project however some of the locations seem to have very high latent gains. The design criteria is pretty standard, 1Person/10m2, 12L/s/p, Casual Gains 90/50W, Small Power Gain 25W/m2, Lighting Gains 8W/m2. Good U-values generally, but some rooms have latent loads > sensible loads.

Hi Grant, the latent loads themselves are calculating fine - the reason they seem comparatively large in relation to the sensible gains is that temperature rise of 2 degrees has been allowed. 
 The effect of this is to reduce the Sensible load - eg see below for room G05, with Temperature Rise allowed and disabled:

You can find further info on the effect of this setting here .
