It's a very late reply but anyway, I would have said to you yes model a zone in the space between the two facades. The innermost will be considered internal though that's the only thing. But that's OK as long as all your U-values are correct. And then this zone should be "Unconditionned" I guess... <BR /> Then try one model without the double facade and compare it with the final design... <BR /> You can also play with the Infiltration values in the Structures tab of the Energy Model Review...<BR /> From a design perspective, I don't know which type of climate this design is based on but a full glass external skin might bring in a whole lot of heat in contact with the internal skin though... Anyway the reason I say this is you know can use the Sunscreen options or External Blind option in the Openings tab of the Energy Model Review to somewhat mitigate the effect, or model a screening device... Type of glazing also important obviously... Mon, 08 Jul 2019 01:09:58 GMT https://community.graphisoft.com/t5/Sustainable-design/Double-Facade-Evaluation/m-p/249113#M1070 chrrev 2019-07-08T01:09:58Z
