Evaluation procedure 83
4) while calculating the energy consumption of internal lighting, the operating hours
considered may differ from the actual operating hours. the same should be verified from
the documentation of criterion 14.
Point allocation
if the rated capacity of the proposed renewable energy system is equal to or more than 1% of the
internal lighting and space-conditioning connected loads or its equivalent in the building, this
mandatory point can be awarded.
Appraisal 18.3.2, 18.3.3, 18.3.4, 18.3.5
18.3.2 rated capacity of proposed renewable energy system meets annual energy requirements
of equal to or more than 5% of internal lighting connected loads or its equivalent in the
building, as per all compliance clauses. (1 point)
18.3.3 rated capacity of proposed renewable energy system meets annual energy requirements
of equal to or more than 10% of internal lighting connected loads or its equivalent in the
building, as per all compliance clauses. (2 points)
18.3.4 rated capacity of proposed renewable energy meets annual energy requirements of equal
to or more than 20% of internal lighting connected loads or its equivalent in the building,
as per all compliance clauses. (3 points)
18.3.5 rated capacity of proposed renewable energy system meets annual energy requirements
of equal to or more than 30% of internal lighting connected loads or its equivalent in the
building, as per all compliance clauses. (4 points)
Required documentation
1) detailed calculations for renewable energy system performance including annual energy
generation.
2) Calculation of connected load for lighting and energy requirement for the same.
Review checklist
1) review the calculations of annual energy generation by the renewable energy system to
ensure that the procedure adopted for calculating the annual energy generation is correct.
Ensure that all the required parameters, such as eiciency of all the components, system
losses, and so on have been considered. values used for calculation should be cross checked
with the information provided by the manufacturer.
Possible errors
1) the value of annual energy requirement for internal lighting used in the calculations
for this appraisal may differ from the value mentioned in the documentation of criterion 14.
Point allocation
one point should be awarded if the proposed renewable energy system meets annual energy
requirements of equal to or more than 5% of internal lighting connected loads or its equivalent in
the building.
two points should be awarded if the proposed renewable energy system meets annual energy
requirements of equal to or more than 10% of internal lighting connected loads or its equivalent in
the building.
