  5. SelectawalltypefortheKeystoneLibraryapplicationandjustifyyourchoice. 6. Includethenewwallconstructioninthebuilding3Darchitecturalmodel. 7. Createasectionview(inthearchitecturalsoftware)throughthenewwall.Label allbuildingcomponents.

 Conclusion 1. Explainwhythematerialsusedinaresidentialwallsystemaredifferentfroma commercialsystem. Residentialbuildingshavedifferentusesandpurposesthancommercial buildings.Alsoresidentialbuildingshavedifferentcodesaboutwhatmaterial touse.Suchas,residentialhomeswilllikelyusewoodandcommercial buildingswilluseconcretebecauseitissafer.    2. Whyisconcreteapopularcommercialconstructionmaterial? Cheap,lowmaintenance,safe,andoverallconvenienttouse.     3. Whatfactorsaffecttheselectionoftheexteriorfaçadeofacommercialstructure? Itdependsonthelookthattheyaregoingforandtheaestheticappealtheyare lookingfor.Itcouldalsodependontheweatherorclimate.
