Hello,

Can someone explain to me how much power I should use to size my HVAC system for my needs in Designbuilder? I have three different values in the DesignBuilder report. I have a value in "ZoneHVAC:IdealLoadsAirSystem", and two others in "HVAC Sizing Summary".

I have another question, how to have one and the same block for the roof and the walls? Currently, they are separate and I have to set up the roof and wall parts separately.

Thanks in advance
