Project background: Extensive renovation to historic two-story building including addition of two new stories above the existing two. Mixed occupancies: 1st floor restaurant, 2nd floor offices, 3rd & 4th floors will be residential units. IBC 2012 and IECC 2012. Location: Washington DC.
I'm trying to figure out the above grade wall construction I need to provide for two scenarios, that meet the IECC 2012 building envelope requirements:
Scenario 1) Existing two story masonry walls, the side walls of which are party walls right up against the adjacent buildings at the property line. What wall construction do I use to get proper insulation? Since they are party walls I have to insulate on the inside of the existing masonry walls. Where can I find the appropriate wall construction?
Scenario 2) New stories 3 and 4 will be metal framed exterior walls with a thin brick veneer on the outside. Per Table C402.2, I know I am Climate Zone 4A, I need R-13+ and R-7.5 continuous insulation on the exterior side of the studs. Where do I find the appropriate wall construction/composition to meet the energy requirements and for this condition?
