Hi, It's the first time I use ecotect and I have a big problem: increasing the thickness of the thermal insulation layer in the external wall the MONTHLY HEATING LOAD decreases, but MONTHLY COOLING LOAD increase! I think it's a very strange thing...
Someone can help me?
You also might look into your zone settings. Verify the occupancy level and the activity, as this might be internal load dominated space and that extra layer of insulation (wall thickness) is preventing building to cool off during the diurnal cycle. Heat is being trapped within that specific zone. You might modify the infiltration rate, size of the opening or the amount of sensible heat being released within that zone.
