Deconstruct Construction

- [source code]
Deconstruct an opaque or window construction into its constituient materials.

Inputs

  • constr [Required]
    An opaque or window construction to be deconstructed. This can also be text for an opaque or window construction to be looked up in the construction library.

Outputs

  • materials
    List of material objects that make up the construction (ordered from outside to inside).
  • layers
    List of material identifiers that make up the construction (ordered from outside to inside).
  • r_val_si
    R-value of the construction in m2-K/W. Note that R-values do NOT include the resistance of air films on either side of the construction.
  • r_val_ip
    R-value of the construction in h-ft2-F/Btu. Note that R-values do NOT include the resistance of air films on either side of the construction.
  • u_fac_si
    U-factor of the construction in W/m2-K. Note that U-factors include the resistance of air films on either side of the construction.
  • u_fac_ip
    U-factor of the construction in Btu/h-ft2-F. Note that U-factors include the resistance of air films on either side of the construction.
  • shgc
    The estimated solar heat gain coefficient (SHGC) of the construction. This value is produced by finding the solution to the relationship between U-value, Solar Transmittance, and SHGC as defined for the simple glazing system material in EnergyPlus.

  • t_sol
    The unshaded shortwave solar transmittance of the construction at normal incidence. Note that 'unshaded' in this case means that all blind + shade materials in the construction are ignored.
  • t_vis
    The unshaded visible transmittance of the window at normal incidence. Note that 'unshaded' in this case means that all blind + shade materials in the construction are ignored.
