Four sampling groups are used for determination of baseline and project
emissions. Two groups serve for determination of baseline and for project
emissions (baseline and project sample groups), with another two serving to
cross-check the results achieved (baseline and project cross-check groups;
these are re-established by random choice at the start of each monitoring
interval): The minimum size of the groups at the start of the project is 100
households, and CERs cease to accrue if the size of a group falls below 60.
Buffer groups can be established to prevent a fall of the group size under
the critical threshold. The distribution of sample group households across
project areas shall be proportional to the lamp distribution pattern across
project areas. Members of the project sample group should not receive
more information than other households and should not be particularly
encouraged to participate in the project. Measurement equipment shall
be installed in all sampled households, either to measure all lamps in the
households or only those in the living areas. This metering equipment, which
can either be an electricity or a run-time meter, has to be attached to the
lamp or the cable, not the socket to prevent that project participants are
involuntarily keeping the lamps distributed by the project. Run-time meters
can only be used if all lamps sold in the host country perform according to
the standards IEC60064 (incandescent lamps) and IEC60901 (CFLs), if the
power rating is measured on site or if the lowest power rating found in the
baseline sample group and the highest power rating found in the project
sample group is used for the calculation. Moreover, a power correction factor
has to be applied that takes into account that lamp electricity use depends
on the actual grid voltage achieved.
Monitoring shall be conducted as follows.
Ex ante
• Power rating of each lamp type distributed, through laboratory
measurements
• Grid voltage
• GPS data to define the project areas;
• Household name, address, GPS data, applicable project area, for all sample
groups;
• Electricity consumption of sample group households according to
electricity invoices
• Date when the household has been added to the sample groups;
• Date of first spot check in sample groups;
• Place and number of lamps found during a first spot checks in the
household/ in its living area;
• Clear identification of each lamp found during a spot check;
• Type of measurement equipment installed for each of those lamps and
date of its installation
• Information whether the lamp and its measurement equipment is working
appropriately,
