2 A. Title of the methodology Introduction of room air conditioners equied with inverters to ublic sector buildings, Version 01.0 B. Terms and definitions Terms Room air conditioner (RAC) Inverter Public sector buildings Energy efficiency ratio (EER) Cooling seasonal erformance factor (CSPF) Definitions A single slit tye air conditioner. A device included in RACs and other motor-oerated aliances, whose function is to vary the seed of the comressor motor in line with different load demand, to enable variable refrigerant flow to otimally regulate the temerature. Buildings owned or administered by national or local government. The ratio of total cooling caacity to rated inut ower in secified conditions. Energy efficiency of RACs factoring into the seasonal temerature variation. Ratio of the total annual amount of heat that the RAC can remove from the indoor air when oerated for cooling active mode to the total annual amount of energy consumed by the equiment during the same eriod. C. Summary of the methodology Items GHG emission reduction measures Calculation of reference emissions Calculation of roject emissions Summary Energy saving achieved by introduction of RACs equied with inverters to ublic sector buildings. GHG emissions associated with electricity consumtion of reference RACs are calculated based on the monitored electricity consumtion of roject RACs, the ratio of the energy efficiency of reference and roject RACs, and the CO 2 emission factor of the electricity consumed by roject RACs. GHG emissions associated with electricity consumtion of roject RACs are calculated based on the monitored electricity 2

Electricity consumtion of roject RACs Project energy efficiency (CSPF of roject RACs) Reference energy efficiency (CSPF of reference RACs) D. Eligibility criteria This methodology is alicable to rojects that satisfy all of the following criteria. Criterion 1 The roject newly introduces RACs equied with inverters, or relaces existing non-inverter RACs by inverter RACs. Criterion 2 This methodology is alicable to ublic sector buildings. Criterion 3 Rated cooling caacity of a roject RAC is within the alicable range of the Vietnamese national standard TCVN7831:2012. Criterion 4 Ozone Deletion Potential (ODP) of the refrigerant used for roject RAC is zero. Criterion 5 Plans to revent release of refrigerants into the atmoshere at the time of RAC removal are reared for both roject RACs and the existing RACs relaced by the roject. In the case of relacing existing RACs by roject RACs, execution of the revention lan is checked at the time of verification, in order to confirm that refrigerant used for the existing RACs removed by the roject is not released to the air.

Establishment and calculation of reference emissions F.1. Establishment of reference emissions 3

4 Reference emissions are established as the roduct of monitored electricity consumtion of roject RACs, the ratio of the energy efficiency of reference and roject RACs, and the CO 2 emission factor of the electricity consumed by roject RACs. The methodology rovides following stewise rocedures to set energy efficiency values of the reference and roject RACs, ex-ost. In the rocedures, reference RACs are conservatively set to results in a net reduction of emissions. Ste 1: Determine reference RACs that lead to net emission reduction Select a reference RAC for each model of roject RAC which meets the following conditions: Not equied with inverters. Categorized as Grade 4 of the energy efficiency grades by EER as outlined in Table 3 of Vietnamese national standard TCVN7830. Cooling caacity of the reference RAC selected for the urose of calculating reference emissions belongs to the same rated caacity class as the roject RAC, based on the three rated caacity classes in Table 3 of TCVN7830. Reference RAC is reviously unused and is currently available in the market at the time of CSPF determination. Ste 2: Determine CSPF of reference RACs CSPF values of selected reference RACs by ste 1 are determined at a third arty testing facility which is equied with a calorimeter caable of determining CSPF in line with ISO5151, following the testing rocedures and conditions outlined in the Vietnamese National Standard TCVN 7831:2012. Ste 3: Determine CSPF of roject RACs CSPF values of roject RACs are determined at a third arty testing facility which is equied with a calorimeter caable of determining CSPF in line with ISO5151, following the testing rocedures and conditions outlined in the Vietnamese National Standard TCVN 7831:2012. Ste 4: Calculate ratio of CSPF of reference and roject RACs for each model For each model, divide the CSPF value of roject RAC by the CSPF value of the relevant reference RAC. Ste 5: Select the reference and roject energy efficiency (CSPF) values for the roject For a given grou of RACs whose electricity consumtion is measured together, select the CSPF values of the reference RAC and the roject RAC calculated in Ste 4 which yields the 4

5 lowest ratio (h PJ / η REF in equation 1) as the reference and roject CSPF values for the roject during the roject life. This ste ensures that ratio of CSPF values used for the urose of calculating reference emissions is conservatively derived for the roject. F.2.
