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. More information can be found at https://bigladdersoftware.com/epx/docs/9-5/engineering-reference/ on this partticular sub-page of the engineering reference: window-calculation-module.html#step-4.-determine-layer-solar-transmittance 
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.
