10 Investment Measures Optimization of AC Load Employee Awareness Savings of 1.24 Lakh kwh in FY Temperature Control Optimize UPS FY14 to FY17 Filter Cleaning Harnessing of Daylight Prevent air leakage

11 Investment Measures FY FY FY Lac kwh 10.1 Lac kwh 8.90 Lac kwh 1 Secondary Pump 1 Condenser Pump New AHUs with VFD 10 nos 2 Condenser Pumps 1 Secondary Pump 3 Primary Pumps Actuator Valves Cooling Towers NRV Installed LED Installation BMS integration HVAC & Lights Savings of 2.8 Lac kwh Savings of 1.2 Lac kwh

12 Investment Project : LED Lighting Retrofit 1750 light fittings replaced into LEDs with required LPD Investment of Rs. 12,24,708 ROI= 10 months Savings of 1,40,000 kwh per year

13 Innovation Projects

14 Innovation 1 : Day Light Harvesting Daylight harvesting in the building Energy Savings 19,000 kwh / year LED lights around the periphery inside the building are switch off.

15 Innovation 2 : Reducing AC Flow in Passages 8 % Savings in Electrical consumption of AHU due to VFD

16 Chillers Performance vs Ageing Oil level, return Oil system & refrigerant level Operation of lube system, motor & starter and Leak checks Voltage and current balance Abnormal sound & vibration Water flow switches Operating parameters, Condenser descaling Timely Replacement of oil filter, drier core & Coolant ATCS installation Eddy current testing of condenser and evaporator

17 Replacement of HVAC Pumps Condenser Primary Secondary Old Capacity of Pump (KW) Power consumed (KW) Efficiency New Outcome Capacity of Pump (KW) Power consumed (KW) Efficiency KW Saving (Annually) Running at a time Total Saving (KWH/Year) 65,664 19,354 16,992 Consolidated Saving of Pumps(KWH) 102,010 Total Saving of (INR) 755, , ,408 Contributed majorly to EnCon

18 Encon Projects Automatic Tube Cleaning System (ATCS) ATCS is hydro-mechanical system Circulates sponge balls through condenser s tubes and keeps them absolutely and Permanently clean. Helps to maintain the condenser approach & pressure thereby saving of air-conditioning s energy consumption. Reduces maintenance and chemical cost. Prevents chillers compressor wear. Improved efficiency of Chillers contributing to Encon

19 Pictures Improvements in AC System Cooling Towers Energy Efficient Pumps (with VFD)

20 Encon Projects Upgrading of BMS Better analysis of data Able to compare and analyze equipment efficiencies HVAC High side & low side, UPS, Lighting load have been segregated and monitored Entire HVAC system has been sequenced Rescheduling of lighting and AHUs Environmental Index maintained at 95. Set point increased from 44 to 55 F Steps to become a smart building

21 Dashboard & Reports AHU Summary Chiller Plant AHU in Detail Cooling Tower

22 Monitoring and Control PPM Schedule Log Sheet PPM Checklist Service Report

23 Encon Projects AC optimisation Chillers Switched off after Office Hours Optimisation of AC by installing Split ACs in Certain meeting rooms and Cabins

24 Journey So Far kwh Specific Energy Consumption % reduction FY 17 over FY FY 14 FY 15 FY 16 FY 17

25 Internal benchmarking EPI as on Mar We are here We were there

26 Involvement & Training Awareness Knowledge Sharing Preventive Mantenance On the Job Training

27 Environment Projects

28 Indoor & Outdoor Plantations More than 250 indoor oxygen generating plants Approx 60 trees including jamun, peepal, sheesham being maintained Trees requiring revival have been identified

29 Reduced Paper Consumption E-statement letters Image based processing Use of electronic format Duplex printing and reuse of paper Use of soft copies for reviews Waste Disposal 1.42 Ton waste FY 2015 reduced to 1.01 Ton FY E waste disposed through registered vendors Reduction of 29% in Waste

30 Solar Renewable Energy 30 kwp Solar roof top Installed Approx. 42,000 kwh generated / annum. Solar generation is 5% of total Energy consumed. Solar roof top Panel is being Maintained and Monitored on daily basis for the units generated.

31 Water Consumption Average per capita consumption : 43 ltrs / day Ensured... Zero discharge Zero leakages Awareness Aerators on Taps

32 GHG Inventory & certification Year FY 2017 tco 2 e

33 Best Practices replicated LED lights replacement - in NCR branches 5 star & energy efficient ACs - procurement in Delhi Zonal Branches Load optimization of UPS all branches/offices APFC panels - installed in large office & branches Energy meters - for monitoring consumption Monthly review meets and sharing of success stories Quarterly Reviews with All Vendors IGBC AP - 5 nos.

34 Summary Encon Projects (3 years) Projects with No Investment Optimization of HVAC, lighting & IT operation Periodic AHU filter cleaning based on equipment based monitoring. Temperature at 24 deg. C Use of Chillers during the office hrs. only Managed Peak & Lean hrs. Avoiding cooling loss Projects With Investment / Innovative Projects Replacement of FTL with LEDs Replacement of HVAC pumps. Replacement of Cooling towers with CTI approved. Replacement of Old AHUs with higher efficiency AHUs with VFDs Water pump replacement Equipment Level Monitoring & control. Environment and Safety Solar generation is 5% of total energy consumed 10 % saving in water consumption 29 % reduction in waste. Total Savings 5 Lac kwh ( 36% ) in last 3 years.
