Criteria for GRIHA rating 65
Criterion 6 Enhance outdoor lighting system effi ciency and
use renewable energy system for meeting outdoor lighting
requirement
Objective
Enhance energy effi ciency of outdoor lighting and promote usage of renewable forms of energy to
reduce the use of conventional/fossil fuel based energy resources.
Commitment
6.1.1 Luminous effi cacy of external light sources used for outdoor lighting shall equal or exceed
as specifi ed.
6.1.2 All outdoor lighting to be fi tted with an automatic on/off switch.
6.1.3 A minimum of 25% of the total number or 15% of the total connected load of outdoor
lighting fi xtures (whichever is higher) to be powered by solar energy. Outdoor lighting
system includes
(i) security lighting,
(ii) street lighting,
(iii) landscape lighting,
(iv) façade lighting, and
(v) parking lighting.
6.2 Compliance
The following documents are to be submitted.
6.2.1 Luminous effi cacy of each type of lamp used in outdoor lighting.
Luminous effi cacy (lm/W) = {lamp lumen output (lm)}/{lamp wattage (W) + ballast power
loss (W)}.
6.2.2 Outdoor lighting layout with manufacturers’ details of lamps, ballasts, luminaires, and
automatic controls. Wiring diagram and placement of automatic switch(es) for outdoor
lighting.
6.2.3 Demarcate solar lighting systems for outdoor lighting in outdoor-lighting layout and give
details of the same.
6.3 Appraisal (maximum points –3)
6.3.1 Luminous effi cacy of 100% of lamps used in outdoor lighting meets the corresponding
lamp luminous effi cacy as per clause 6.2.1 (1 point).
6.3.2 Automatic controls for 100% of outdoor lights, as per clause 6.1.2 (1 point).
6.3.3 Percentage of total outdoor lighting fi xtures with solar lighting system, as per clause 6.1.3
(a minimum of 25% of total number or 15% of total connected load, whichever is higher
(1 point)
