Full-Fuel-Cycle Energy and Emission Factors for Building Energy Consumption –

The definition of FFC energy used throughout this report is as follows: Full-fuel-cycle energy is the energy consumed by an appliance, system, or building as measured at the building site plus the energy consumed in the extraction, processing, and transport of primary fuels such as coal, oil, and natural gas; energy losses in thermal combustion in power-generation plants; and energy losses in tran. [...] The definition of FFC energy used throughout this report is as follows: Full-fuel-cycle energy is the energy consumed by an appliance, system, or building as measured at the building site plus the energy consumed in the extraction, processing, and transport of primary fuels such as coal, oil, and natural gas; energy losses in thermal combustion in power-generation plants; and energy losses in tran. [...] On the other hand, full-fuel-cycle measurement of the energy consumption of appliances and the overall home from the point of extraction to the point of use does account for energy losses that occur (e.g., in the production of natural gas or in the generation of electricity). [...] Page 13 Full-Fuel-Cycle Energy and Emission Factors for Building Energy Consumption – 2013 Update The following sections provide a review and compilation of the latest available data for calculations of source-to-site energy efficiency and emission factors as well as overall FFC energy conversion factors for electricity and fossil fuels used in U. [...] Table 32 shows similar calculations for non-baseload power plants The results of the regional and national comparison indicate that the FFC energy consumption of the gas water heater was always less than the electric water heater, but the savings varied significantly depending on the electricity generation mix in the eGRID sub-region, and whether the analysis used average generation mix or non-bas.
