Calculate baseline building emissions (Equation 1)

Equation (1) of AMS-II.E consolidates baseline greenhouse gas emissions from thermal fuels and electricity consumption in buildings.

calculate_baseline_building_emissions(
  baseline_data,
  thermal_energy_col = "baseline_thermal_energy_gj",
  thermal_emission_factor_col = "baseline_thermal_emission_factor_tco2_per_gj",
  electricity_col = "baseline_electricity_mwh",
  electricity_emission_factor_col = "baseline_electricity_emission_factor_tco2_per_mwh",
  group_cols = NULL,
  output_col = "baseline_emissions_tco2e"
)

Arguments

baseline_data

A tibble describing counterfactual building energy use.

thermal_energy_col

Column storing baseline thermal energy demand (GJ). Set to NULL when thermal fuels are not part of the baseline scenario.

thermal_emission_factor_col

Column storing thermal emission factors (tCO2e per GJ). Required when thermal_energy_col is supplied.

electricity_col

Column storing baseline electricity consumption (MWh). Set to NULL to omit electricity emissions.

electricity_emission_factor_col

Column storing electricity emission factors (tCO2e per MWh). Required when electricity_col is supplied.

group_cols

Optional character vector of grouping variables to retain in the output.

output_col

Name of the resulting emission column.

Value

A tibble with grouped baseline emissions in tCO2e.

Examples

baseline <- tibble::tibble(
  building_id = c("Office_A", "Office_B"),
  baseline_thermal_energy_gj = c(420, 380),
  baseline_thermal_emission_factor_tco2_per_gj = c(0.056, 0.052),
  baseline_electricity_mwh = c(120, 95),
  baseline_electricity_emission_factor_tco2_per_mwh = c(0.62, 0.62)
)
