This component calculates the environmental impact of a building element, connecting the Grasshopper definition with the Rhino model of the building.

INPUT:

  • The "Component Properties" input will take the already-defined components from the .

  • The "Thermal Resistivity" model differentiates between the scenarios of U-value calculations:

- In case of elements exposed to air, the value of 0.17 is added to the calculated U-value from the layers. this includes "Internal Walls", "External Walls", "Roofs", and "Ceilings". - In case of "Floors", the value of 0.13 is added to the calculated U-value from the layers. - In other cases, the U-value is calculated normally.

  • The "Surface Area" input is where the parametric model can be connected to the plugin, either by using the take-off script (in the example file) or other possible methods.

OUTPUT:

LCA Factors (Text) provides the impact headers and values together for better readability, and LCA Factors (Values) is the output that should be used through the workflow.

Additionally, the U-value output provides the thermal transmittance of the element.

the UA-value output provides the multiplication of the U-value with the element's surface area.
