Hi all,

I am using E+ for the thermal simulation of a room having double skin facade (DSF) in south direction. In order to determine the temperature of each surfaces of the DSF and more, I have considered it as a separate thermal zone. However, the size (HLW) of this thermal zone is only 2501801.3 cm. Here 1.3 cm is air cavity thickness between two facades. In the literature thermal zone of size (HLW), 2017020 cm can found where E+ has been used. For example: http://www. sciencedirect.com/science/ article/pii/S0378778814001571 The question is up to what minimum zone size the E+ can simulate accurately? Is there any reference document in this regards? The considered thermal zone has natural air flow facility.

Thank you in advance

In order to determine the temperature of each surfaces of the DSF and more, I have considered it as a separate thermal zone. However, the size (HLW) (HxLxW) of this thermal zone is only 2501801.3 250x180x1.3 cm. Here 1.3 cm is air cavity thickness between two facades. In the literature thermal zone of size (HLW), 2017020 (HxLxW), 20x170x20 cm can found where E+ has been used. For example: http://www. sciencedirect.com/science/ article/pii/S0378778814001571 used (example).

The question is up to what minimum zone size the E+ can simulate accurately? Is there any reference document in this regards? regards?
