Figures needed to determine total building energy consumption:
Performance Year Baseline Year
Grid-purchased electricity 446380 MMBtu 337660 MMBtu
Electricity from on-site renewables 0 MMBtu 0 MMBtu
District steam/hot water (sourced from offsite) 0 MMBtu 0 MMBtu
Energy from all other sources (e.g., natural gas, fuel oil, propane/LPG, district chilled water, coal/coke, biomass) 638583 MMBtu 471872 MMBtu
Total 1084963 MMBtu 809532 MMBtu
