  "text": "The relative CO2 reduction potential ΔCO2(t) for different parking times shall be calculated using formula 5 with the following input data:\ndecay constant of the eco-innovation vehicle without an engine compartment encapsulation (baseline vehicle): dB [1/h]. This value shall be calculated with formula 1;\ndecay constant of eco-innovation vehicle with an engine compartment encapsulation: dE [1/h]. This value shall be calculated with formula 1;\nHot Start Benefit: HSB. This value shall be calculated with formula 2;\nparking time distribution (share of vehicle stops): SVS. Table 2 (below) shall be used;\nCO2 type-approval value: TACO2 [g CO2/km], i.e. CO2 mass emissions combined.\nFormula 5: ΔCO 2 = 1,443 × ln e − d E × t + 1 e − d B × t + 1 × HSB\nThe calculation results shall be given in the following Table 1:\nTable 1\nRelative CO2 reduction potential ΔCO2(t) for different parking times\nParking time [h]\n0,5\n1,5\n2,5\n3,5\n4,5\n5,5\n6,5\n7,5\n8,5\n9,5\n10,5\n11,5\nΔCO2(t) [%]\nParking time [h]\n12,5\n13,5\n14,5\n15,5\n16,5\n17,5\n18,5\n19,5\n20,5\n21,5\n22,5\n23,5\nΔCO2(t) [%]\nThe total CO2 savings, weighted by the parking times (pt) shall be calculated using formula 6.\nFormula 6: C CO 2 = TA CO 2 × ∑ pt = 1 24 ΔCO 2 t pt × SVS pt\nWhere the values for parking time [h] and SVS [%] shall be those in Table 2:\nTable 2\nParking time distribution (share of vehicle stops)\nParking time [h]\n0,5\n1,5\n2,5\n3,5\n4,5\n5,5\n6,5\n7,5\n8,5\n9,5\n10,5\n11,5\nSVS [%]\n36\n13\n6\n4\n2\n2\n1\n1\n3\n4\n3\n1\nParking time [h]\n12,5\n13,5\n14,5\n15,5\n16,5\n17,5\n18,5\n19,5\n20,5\n21,5\n22,5\n23,5\nSVS [%]\n1\n3\n3\n2\n1\n1\n1\n1\n1\n1\n1\n1\nThe CO2 savings shall be the type-approval value (CO2 mass emissions combined) multiplied by a factor of x. The value of x is equal to the term ∑ ΔCO 2 t pt × SVS pt of formula 6.\nWhere an existing vehicle type is equipped with the innovative technology the following formula shall be used:\nFormula 7: C CO 2 = x * TA CO 2 baseline vehicle\nwith:\nCCO2 CO2 savings [g CO2/km]\nTACO2 baseline vehicle type-approval value of the eco-innovation vehicle without an engine compartment encapsulation [g CO2/km]\nWhere the innovative technology is installed on a new vehicle type and the type-approval CO2 value has been determined with the innovative technology installed, the following formula for calculating the CO2 savings shall be used:\nFormula 8: C CO 2 = x ∕ 1 − x *TA CO 2 new vehicle type\nwith:\nCCO2 CO2 savings [g CO2/km]\nTACO2 new vehicle type type-approval value of the new vehicle type equipped with the innovative technology [g CO2/km]",
