Section Env-A 4708.06 - Emissions Baseline Determination(a) The emissions baseline shall be determined in accordance with this section, based on energy usage in MMBtu by fuel type for each energy conservation measure, derived using historic fuel use data from the most recent calendar year for which data are available, and multiplied by an emissions factor and oxidation factor for each respective fuel.(b) The emission and oxidation factors shall be as specified in Table 4708- 1, below: Table 4708-1 Emissions and Oxidation Factors
| Fuel | Emissions Factor (lbs. CO2/MMBtu) | Oxidation Factor |
| Natural Gas | 116.98 | 0.995 |
| Propane | 139.04 | 0.995 |
| Distillate Fuel Oil | 161.27 | 0.99 |
| Kerosene | 159.41 | 0.99 |
(c) The baseline energy usage of the application to be targeted by the energy conservation measure shall be isolated in a manner consistent with the provisions of Env-A 4708.08(e).(d) Annual baseline energy usage shall be determined as follows: (1) "BEUAECM" means the annual pre-installation baseline energy use by fuel type in MMBtu attributable to the application(s) to be targeted by the energy conservation measure(s). If applicable building codes or equipment standards require that equipment or materials installed as part of the offset project meet certain minimum energy performance requirements, baseline energy usage for the application shall assume that equipment or materials are installed that meet such minimum requirements. For offset projects that replace existing combustion equipment, the assumed minimum energy performance required by applicable building codes or equipment standards shall be that which applies to new equipment that uses the same fuel type as the equipment being replaced;(2) "A" means adjustments, determined in accordance with the applicable requirements of Env-A 4708.08, to account for differing conditions during the 2 time periods, pre- installation and post-installation, such as weather, building occupancy, and changes in building use or function; and(3) Energy usage shall be the product of the annual pre-installation baseline energy use by fuel type times the adjustments, as shown in the following equation: Energy Usage (MMBtu) = BEUAECM x A
(e) Annual baseline emissions shall be determined as follows: (1) "i" means the type of fuel;(2) "BEUi" means the annual baseline energy usage for each fuel type in MMBtu, determined in accordance with Env-A 4708.08;(3) "EFi" means the emissions factor in lbs. CO2/MMBtu for each fuel type, from Table 4708-1;(4) "OFi" means the oxidation factor for each fuel type, from Table Env-A 4708-1; and(5) The annual baseline emissions is the sum for all fuel types of the product of the annual baseline energy usage times the emissions factor times the oxidation factor, as shown in the following equation: Emissions (lbs. CO2) = [SIGMA]n BEUi x EFi x OFi
i = 1
