Doors/windows and frames (1 point), as per GRIHA.
Responsibility: Architect
Energy: Renewable
Criterion 18 Renewable energy utilization
Commitment
Rated capacity of proposed renewable energy systems is equal to or more than 1% of internal
lighting and space conditioning connected loads and meets energy requirements for a minimum
of 5% of the internal lighting consumption (for general lighting or its equivalent from renewable
energy sources[solar, wind, biomass, fuel cell and others]). Energy requirements will be calculated
based on realistic assumptions which will be subject to verifi cation during appraisal (5 points).
Mandatory clause
Rated capacity of proposed renewable energy system is equal to or more than 1% of internal lighting
and space conditioning connected loads or its equivalent in the building (1 point–mandatory), as
per all compliance clauses.
Responsibility: Electrical Consultant
Optional clause
Rated capacity of proposed renewable energy system meets annual energy requirements of equal
to or more than 5% of internal lighting consumption or its equivalent in the building (1 point), as
per all compliance clauses.
Responsibility: Energy Consultant
Rated capacity of proposed renewable energy system meets annual energy requirements of equal
to or more than 10% of internal lighting consumption or its equivalent in the building (2 point), as
per all compliance clauses.
Responsibility: Energy Consultant
Rated capacity of proposed renewable energy system meets annual energy requirements of equal
to or more than 20% of internal lighting consumption or its equivalent in the building, as per all
compliance clauses (3 points).
Responsibility: Energy Consultant
Rated capacity of proposed renewable energy system meets annual energy requirements of equal
to or more than 30% of internal lighting consumption or its equivalent in the building, as per all
compliance clauses (4 points).
Responsibility: Energy Consultant
Note: Lighting design shall be based on minimum requirements as per NBC 2005 (BIS 2005d) (criterion 13.1.5).
Criterion 19 Renewable-energy-based hot water system
Commitment
Meet 20% or more of the annual energy required for heating water through renewable energy
based water-heating systems. (3 points)
