Depends on you wall build...could you describe it? The tables in Appx A include for elements without insulation.
Two short questions about modeling the envelope:
1. For my proposed model, am I required to follow the tables from appendix A even when my project is outside the US? In Peru, our reality is that there is no insulation for envelope elements of buildings; so what would be my input data for tables A?
2. For my baseline model, is it ok if I model just one layer as long as it fits the U-value in the table 5.5-X?
Thanks in advance.
