Summary

GHG emission reduction

Reduction of electricity and fossil fuel consumed by existingmeasuresfacilities is achieved by replacing or substituting these facilities
with high efficiency equipment defined in Table 1 of theeligibility criterion 1.

Calculation of reference

Reference emissions are calculated by multiplying electricity

emissionsand fossil fuel consumption of the project by the ratio ofefficiency of reference and project equipment, and emission
factors of electricity and fossil fuel.
For the installation of high efficiency lighting, reference2

JCM_VN_F_PM_ver01.0

emissions are calculated using rated electricity consumption ofthe lighting multiplied by operation hours.
Calculation of project

Project emissions are calculated based on monitored electricity

emissionsand fossil fuel consumption in the project.

Monitoring parameters

Electricity and fossil fuel consumption of the high efficiency
equipment
Operating hours of the high efficiency equipment and auxiliary
equipment, where applicable

D. Eligibility criteria
This methodology is applicable to projects that satisfy all of the following criteria.
Criterion 1

The project involves implementation of one or more energy efficiency measures
categorized in Table 1 by using high efficiency equipment at an existing facility.
Projects involving installation of high efficiency lighting need to be coupled withanother energy saving measure(s) in order to be eligible under this methodology.
High efficiency equipment introduced by the project replaces the existing
equipment or substitutes the output of the existing equipment, and it is includedin the applicable technologies as shown in Table 1:

Criterion 2

If the existing equipment is a chiller containing CFCs, HFCs, or HCFCs and isremoved due to the project, a plan to prevent release of refrigerant used for theexisting chiller into the atmosphere is prepared. Execution of the prevention plan3JCM_VN_F_PM_ver01.0

is checked at the time of verification, in order to confirm that the refrigerant used
for the existing chiller is not released to the air.
Criterion 3

High efficiency equipment in the project guarantees a better performance than
the reference equipment for a minimum of one year.
The performance level can be confirmed by comparing the efficiency or rated
electricity consumption between the high efficiency equipment and the reference
equipment, with an evidence of either a manufacturer’s performance guarantee
or energy saving company’s (ESCO) energy saving guarantee of high efficiencyequipment. Where such evidence is not available for the reference equipment,high efficiency equipment in the project guarantees a better performance than thedefault efficiency values provided in the methodology.

F. Establishment and calculation of reference emissions
F.1. Establishment of reference emissions
Reference emissions are calculated by multiplying electricity (ECREF,i,p) and fossil fuel
(FCREF,i,p) consumption of the project by the ratio of efficiency of reference and projectequipment, and emission factors of electricity and fossil fuel. Individual electricity and fossil
fuel consumption are derived from monitored fuel and electricity consumption by the high4

Energy efficiency measures

The methodology ensures net emission reductions by the followings:
1) Adopting conservative default efficiency values for calculation of reference emissions-Boilers: applying CDM default efficiency for new boilers;-Chillers: design efficiency of models sold by dominant manufacturers in the chiller market
in Vietnam2) Implementation of multiple measures
Among the three measures introduced in this methodology, one measure (installation of highefficiency lighting) may have a possibility where the calculation result will not demonstrate net
emission reductions due to the way the equation is formulated. In order to ensure the net
emission reductions, the methodology requires to implement together with other energy
efficiency measure(s) stated in table 1 under the eligibility criteria.

G. Calculation of project emissions
Project emissions are calculated as a sum of emissions from electricity (ECPJ) and fossil fuel(FCPJ) consumption in the project. The emission from electricity consumption is calculated bymultiplying electricity consumed by the project (ECPJ,i,p) by the CO2 emission factor ofelectricity (EFCO2,ELEC). The emission from fuel consumption is calculated by multiplying fuelconsumed by the project (FCPJ,i,j,p) by the emission factor of the fuel (EFCO2,j).
