Constructions need to accommodate more types of insulation values

[nealkruis]

Some rulesets characterize constructions with multiple R-values, for example:

• Cavity vs. Continuous R-values
• Slab edge vs. perimeter R-values

[JasonGlazer]

@nealkruis we currently have data elements:

• insulation_location which is a string but only because I wasn't sure of the proper enumeration
• r_value which is numeric

What if I make both lists and create a general enumeration of cavity, continuous, slab edge, perimeter. The enumeration and value correspond but can have as long of a list as necessary. What do you think?

We use the list of enumerations and values when we are describing mechanical efficiencies and stuff so it is not a new structure.

Maybe we should split continuous into exterior_continuous and interior_continuous, agree?

Can you think of any other enumeration values?

[nealkruis]

I think this is the right approach. There are a lot of possible combinations of foundation related insulation:

• Horizontal vs. Vertical
• Interior vs. Exterior
• Slab gap vs. slab edge
• Whole slab
• Different depths
• Partial wall insulation

Based on my somewhat limited knowledge in this area, I came up with the following enumeration. Please let me know what is still missing.

InsulationLocationOptions:
  Object Type: "Enumeration"
  Enumerators:
    ABOVE_GROUND_WALL_EXTERIOR_CONTINUOUS:
      Description: "Continous insulation on exterior of an above ground wall"
    ABOVE_GROUND_WALL_INTERIOR_CONTINUOUS:
      Description: "Continous insulation on interior of an above ground wall"
    ABOVE_GROUND_WALL_FULL_CAVITY:
      Description: "Insulation within the cavity of an above ground wall that fills the entire cavity"
    ABOVE_GROUND_WALL_PARTIAL_CAVITY:
      Description: "Insulation within the cavity of an above ground wall that fills only part of the cavity"
    SLAB_HORIZONTAL_PERIMETER:
      Description: "Insulation on underside of the slab covering the perimeter"
    SLAB_HORIZONTAL_FULL:
      Description: "Insulation fully covering the underside of the slab"
    SLAB_VERTICAL:
      Description: "Insulation applied vertically next to edge of slab"
    NONE:
      Description: "None"
    OTHER:
      Description: "Other"

@nealkruis if I am missing any enumerations that make sense, please open a new issue for them.
