Scenario 1: Building Envelope-Related Design Decisions

  • Thermal Properties of Wall Surface (Wall Construction): R13 Wood to 14-inch ICF
  • Glazing % (Window-to-Wall Ratio) for each orientation (North, South): 0%
  • Glazing % (Window-to-Wall Ratio) for each orientation (East, West): 15%-40%
  • Thermal Properties of Glazing Surfaces for each orientation (East, West): TrpLoE
  • Window Shading amount for each orientation (East, West): 2/3 Win Height
