message_ix_models.model.buildings.build.get_tech_groups

message_ix_models.model.buildings.build.get_tech_groups(spec: Spec, include='commodity enduse', legacy=False) → Mapping[str, Sequence[str]][source]

Return groups of buildings technologies from spec.

These are suitable for aggregation, e.g. in data preparation or reporting.

Parameters:

  • spec – The result of get_spec().

  • include (str or Sequence of str) –

    May include specific values to control what is returned:

    • ”commodity”: include keys like “resid gas”, where “gas” is a commodity, collecting technologies which consume this commodity.

    • ”enduse”: include keys like “comm other_uses”, where “other_uses” is a buildings energy end-use, collecting technologies which represent this end-use.

  • legacy – if True, apply mapping from commodity names to labels used in legacy reporting code; e.g. “electr” becomes “elec”.
