1. Energy Management – The case of a strategic Initiative

2. Agenda
Let me take it up with Ramanujan IT City’s experience on EnMS with the following 3 questions
and its response……..
• WHY EnMS
• HOW did we implement the same
• WHAT IS THAT WE ACCHIEVED SO FAR..

3. Why EnMS – 50001 is a strategic
Intervention
• Ramanujan IT city is a multi tenanted complex where the operation cost is significant.
• Initial investment of 10% on project cost has been made on green initiatives at the
construction stage. But what is more important is the operation cost.
• Power is a major input resource for the TRILs function as a service provider for property and
infrastructure management..
• Generation and O&M of power is becoming increasingly critical as the major share in the
Operation cost is cost of power.

5. Why EnMS – 50001 is a strategic
Intervention
• 26 MW of installed Capacity , at full scale operation is expected generate CO2 emissions
around 63000 t / year.
• Sustainability is a critical issue that needs to be addressed.
• The strategic options available are …

7. Why EnMS – 50001 is a strategic
Intervention
.
• It is not suffice to look at alternate low carbon energy sources but to look at energy
efficiency.
• Investments in Energy efficiency is expected to result in a pay back of less than 5 years for
the developer end-user combine.
• EnMS is a decisive step in this direction.

8. HOW – The implementation Journey
• Ramanujan IT city / TRIL was certified for IMS in June 2011
immediately after which the EnMS was taken up.
• The EnMS certification was completed in march 2012.
• The EnMS was also integrated with the IMS.
• The scope was for Ramanujan IT city project which is of 4.5
million sft.

11. WHAT – IS ACHIEVED SOFAR
• Bench Marking for critical energy parameters started.
• Possibility too coach team members to contribute better for
energy efficiency
• Clarity of Roles and responsibilities and expectations
• Issues related to HVACs diagnosed and corrective taken.
• Focus n energy management has given better sales
advantage.
