1. Simple Steps
to Save Energy

2. Current Status

• November 5,177,814.70 235,417.00
• December 5,207,974.20 237,062.00
• Average Electricity Cost per Month (Rs./Month) = 5,184,614.61
• Average Unit Consumption per Month (kwh/Month) = 236,631.92

3. Usable Area
• Tower II
• 1st to 5th Floor = 14,100.84 x 5 sq.ft
• 6th to 11th Floor = 10,118.16 x 6 sq.ft
• Tower I
• 1st to 10th Floor = 2,408 x 10 sq.ft
• 11th Floor = 2,258 sq.ft
• Kingfisher Floor = 1,540 sq.ft
• Mezzanine Floor = 446 sq.ft
• Total Usable Floor Area = 159,537.16 Sq. ft.
= 14,821.49 m2

4. Overall Status
• Approximate cost per
unit area per month = 32.50 Rs/(Sq.ft, Month)
= 349.80 Rs/(m2, Month)
= 4,197.60 Rs/(m2, Year)
• Approximate unit consumption per
unit area per month = 1.48 kwh /(sq. ft, month)
= 15.97 kwh /(m2, month)
= 191.64 kwh /(m2, Year)
• Accepted Green Building
Standards = 1.25 -1.41 kwh/(Sq ft, month)
= 161.46 – 182.13 kwh / (m2, Year)

5. Air Conditioning
• More than 50% of total electricity cost has
being used for the cooling purpose.
 Recommendation:
 Minimum usage of the chiller on Sunday, Poya day, and after working
hours.
 Switch off the FCU (Fan Coil Unit) during lunch hour and after working
hours.
 The solar film can be pasted on the windows that adjacent to the cubicle

6. Lighting
• Main Lobby, Service lobbies and toilets are
designed for natural lighting.
 Recommendations:
 Toilets, passages to be switched off when ever it is not necessary.
 Switch off unnecessary lighting during non working hours.
 Designate a personnel take care of the lighting saving.

7. Raw Power And UPS
Energy Consumptions:
• Desk Top: 60-250W
• On Screen : 60-250W
• Sleep stand by: 1-6W
 Recommendations:
 Policy to implement Hibernate/Sleeping/Power economy option as
mandatory.
 Switch off all computers after work. We have identified that the night
time consumption is higher that expected.
 Switching off Photocopiers when not in use.
 Use water dispensers and fridges efficiently.
 Look for energy star rating when purchasing the equipment.

8. Energy Audit
• Preliminary Energy Audit could be carried out by us with the
assistance of the floor energy representatives.
• New Analyzers will be fixed which will give a more precise
measurement.
