602.2.2 Onsite Nonrenewable Energy
JUMP TO FULL CODE CHAPTER
Emissions associated with the use of nonrenewable energy sources other than electrical power such as natural gas, fuel oil, and propane shall be calculated by multiplying the fossil fuel energy used by the building and its site at the utility meter by the national emission factors in Table 602.2.2 and the conversions required by this section. Emissions associated with fossil fuels not specified in Table 602.2.2 shall be calculated by multiplying the fossil fuel used by the building at the utility meter by 250. Emissions associated with purchased district energy shall be calculated by multiplying the energy used by the building at the utility meter by 150 for hot water and steam, and for district cooling, the factors from Table 602.2.2 based on the EPA eGRID Sub-region in which the building is located.
TABLE 602.2.2
FOSSIL FUEL EMISSION FACTORS
| EMISSION RATE (lb/MMbtu HHV) | NATURAL GAS AS STATIONARY FUEL | FUEL OIL AS STATIONARY FUEL | PROPANE AS STATIONARY FUEL |
| CO2e | 137.35 | 200.63 | 162.85 |
For SI: MMBtu = 1,000,000 Btu = 10 terms: HHV = High-heating value.
