message_ix_models.model.buildings.build.adapt_emission_factors

message_ix_models.model.buildings.build.adapt_emission_factors(data: MutableParameterData) → None[source]

Adapt relation_activity values in data that represent emission factors.

In MESSAGEix-GLOBIOM, relation_activity entries for, for instance, r=CO_Emission are computed as (emission factor for fuel, species) × (input efficiency of technology consuming the fuel). Because the MESSAGE-Buildings representation sets the latter to 1.0, the relation_activity entries must be recomputed.

This function updates the values in data["relation_activity"], assuming that data["input"] contains the original (base model, MESSAGEix-GLOBIOM) input efficiencies. Then it sets data["input"]["value"] to 1.0.

Todo

When available in message_ix_models, simply read the values for each (fuel, species) from a file, rather than performing this calculation.
