Normalized results

This method returns the normalized impact assessment result of the calculated product system. Mathematically, it is the impact assessment result \(h\) devided by the respective normalization values \(nv\):

$$ diag(nv)^{-1} * h $$

Examples

JSON-RPC via Fetch API

The example below shows the usage of this method using the JSON-RPC protocol via the Fetch API which is available in modern web-browsers or platforms like Deno.

  let resp = await fetch("http://localhost:8080", {
    method: "POST",
    body: JSON.stringify({
      jsonrpc: "2.0",
      id: 1,
      method: "result/total-impacts/normalized",
      params: {
        "@id": "15432ac4-7752-4066-a62d-31270f6a0dbd",
      }
    })
  });
  let v = await resp.json();
  console.log(v);
  //{
  //  jsonrpc: "2.0",
  //  result: [
  //    {
  //      impactCategory: {
  //        "@type": "ImpactCategory",
  //        "@id": "248a3f3f-933e-3c45-a799-fad9f956e03c",
  //        name: "Photochemical ozone formation",
  //        category: "EF 3.0 Method (adapted)",
  //        refUnit: "kg NMVOC eq"
  //      },
  //      amount: 0.0010466725460636012
  //    },

olca-ipc.py

The example below shows how to get normalized impact assessment results using olca-ipc.py:

import olca_ipc as ipc
import olca_schema as o

client = ipc.Client()

# get the impact assessment method
method = client.get(o.ImpactMethod, "bf665139-3159-45ef-9b00-f439251d2b5b")

# select the first normalisation & weighting set for the example;
# make sure the method has nw-sets
nwset = method.nw_sets[0]

# run a calculation
result = client.calculate(o.CalculationSetup(
    target=o.Ref(
        id="7d1cbce0-b5b3-47ba-95b5-014ab3c7f569",
        ref_type=o.RefType.ProductSystem,
    ),
    impact_method=method.to_ref(),
    nw_set=nwset.to_ref(),
))
result.wait_until_ready()

# print the normalized results
for nr in result.get_normalized_impacts():
    print(f"{nr.impact_category.name} :: {nr.amount}")

result.dispose()
