I simulated with adiabatic wall vs constructions with very very low thermal transmittance for a single zone example. I got more realistic results with second option construction. What´s the e+ way to create zero heat flux boundary conditions for exterior surfaces? thanks

From the Input Output Reference, the "Adiabatic" outside boundary condition will not transfer heat out of the zone, but will still store heat in thermal mass. So, a very lightweight adiabatic wall should result in near-zero heat transfer in/out of the wall.
