Baseline System Configurations:

1.    Compared to a solid CMU wall with 2.5” thick XPS, R value = 12.5 with metal Z girts 16” oc.
Effective R-value of 4.6 (U=.2174)

2.    Compared to typical 4 ½” thick gypsum-based wall with 3 1/2 metal studs, R-11 fiberglass batt and 5/8″ exterior sheathing.
Effective R-value of R-6.09 (U=.1639)

3.    Compared to a typical 7” thick gypsum-based wall with 6” metal studs, R-19 fiberglass batt insulation and 5/8” exterior sheathing.
Effective R-value of 10.9 (U=.0917)

Building model parameters:

Window areas are not included. The height of the model building walls is 14′ per story, with a total of three stories. The study assumed natural gas furnace for heating with 90 percent efficiency and utilization of electricity for cooling with a SEER of 10.Calculations are based on average heating and cooling degree-day data located at ncdc.noaa.gov. Calculations are based on opaque wall area with conductive heat loss.

U values of SMARTci systems for sample cities:

  •        Ft Lauderdale and San Francisco are .0793
  •       Houston are .045825
  •       New York, Chicago are .0401
  •       Minneapolis, Fargo and Fairbanks are .0357
