6 Load Distribution of the Building 56% HVAC 3 x 250 TR Air cooled VSD MCX coils 1.08 ikw/tr 18% IT 350 kva UPS TFT Desktops MFM printers Hub rooms 16% Other Canteen Elevators Pumping Stand alone AC 10% Lighting LED 0.6 W / Sq.ft Pull cords

7 Annual Energy consumption Annual Energy Consumption Lac kwh % savings in last 3 years FY 2015 FY 2016 FY 2017 FY Lac kwh Savings 770 Tons of CO 2 emissions avoided

8 Specific Energy Consumption EPI normalized for 11 hrs National Benchmark FY 2015 FY 2016 FY 2017 FY 2018 TCS Kochi 25.41% reduction in SEC 5 STAR Warm & Humid zone

9 Internal benchmarking EPI as on Mar

10 EnCon projects implemented in FY 2016 Equipment based monitoring & control Trimming of AHU & chiller plant operation timings by 30 mins. Set point increased to 10 Deg C VFD on secondary pumps made operational Choking of condenser coils identified Savings 2.30 Lac kwh UPS optimisation Before kva After 350 kva Savings 0.78 Lac kwh Investment Rs. 50 Lacs Savings 3.08 Lac kwh EPI reduced from 130 to 115

11 EnCon projects implemented in FY 2017 Pull Cords EC Motor DC Fans Energy Valve on AHU * Individual lighting control * Savings of 0.28 lac kwh p.a. * Investment Rs. 14 Lacs * Payback 50 months * 50% reduced motor capacity * Savings of 0.42 lac kwh p.a. * Investment Rs Lacs * Payback 23 months * 60% reduced motor capacity * Savings of 0.03 lac kwh p.a. * Investment Rs Lacs * Payback 19 months * Dynamic balancing right flow at all times * Savings of 0.03 lac kwh p.a. * Investment Rs Lacs * Payback 19 months

12 EnCon projects implemented in FY 2017 Total Savings 4.20 lac kwh BMS Intervention * Auto operation of plant * Dynamic set point enabled * Optimised control & efficiency * Savings of 2.80 Lac kwh p.a. Wastage elimination * No Traffic during Night. * Operating Temp range of Switches is up to 42 o C * Maintaining Temp. of 28 o C in Hub Rooms * Savings of 0.64 Lac kwh p.a. Total Investment Rs Lac EPI reduced from 115 to 100 No Investment

13 Planned EnCon projects in FY 2018 Sr. Description Remarks Status 1 Separate Standalone AC system for 24 x 7 Working Areas Less Chiller efficiency on very low Loads. 2 HVLS Fans For Atrium 3 VAV & VFD for All Ceiling Suspended AHU s Simultaneous Control of Chilled water & Air Completed Evaluated & dropped Evaluated & dropped

14 Innovative Project implemented in FY18 Day time ikw/tr 0.97 Night time ikw/tr 1.37 Night 42% higher ikw/tr 350 kwh

15 Action taken & savings 23 TR load during night time & full day on holidays. Poor efficacy of chillers on low load Unitary system provided ( Split AC ) & fans Investment Rs Lacs Total Annual Savings 60,000 kwh & Rs Lacs Simple Payback 16 months

16 Innovative Project implemented in FY18 Background Training facility on 2 nd floor Peak Occupancy 200 Requests for lowering the temp. set points Although AHU set point lowered, cooling was not achieved hence Chiller outlet set point was reduced by 1 to1.5 Deg C Other floor occupants experiencing chillness In case of less occupancy, cooling was wasted Occupant dis-comfort & Energy wastage

17 Innovative solution deployed VFD acts as DDC panel with all intelligence stand-alone User can set temperature & VAV will modulate As VAV operates, AHU speed is controlled by VFD VFD also controls Chilled Water valve to control flow 90% control on Air & 10% control on chilled water 6% savings achieved 0.10 Lac kwh Collaboration with OEM

18 Projects evaluated in 2018 & dropped HVLS fan - Payback was 5.5 years - Aesthetics - Safety - CAPEX & OPEX both were high VAV & VFD for all AHU - Duct layout demanded more than 1 VAV - Variation in speed of Fan was low - Payback was 5 years

19 Summary of EnCon projects Sr. No. Description Lac kwh Savings Investment Lac Rs. Year of action 1 Equipment based monitoring & control 2.30 Nil FY UPS optimisation 0.78 Nil FY EC Blower for AHU 8 nos FY Pull chords for lighting control FY DC fans in Canteen FY Energy valve for AHU FY Chiller sequencing 2.80 Nil FY Hub room AC switched OFF 0.64 Nil FY Stand-alone AC for night operations FY VAV/VFD for Training rooms FY 2018 Grand Total EPI reduced from 130 to 97

20 Plans for reduction in SEC i.e.epi Sr. No. Activity 1 UPS replacement 2 Hot desk concept for extended & holiday working hrs 3 Replacement of AHU blowers with PM motors in AHU Target to achieve savings of 1.25 Lac kwh & reduction in EPI by 5 points

21 Utilisation of renewable energy sources Open Access PPA 1.5MWp Solar power contract Lac kwh in FY kwp Roof top Solar OPEX based 0.81 Lac kwh in FY 2018 Solar water heating 750 LPD capacity Utensil washing 0.05 Lac kwh Total 17.3 Lac kwh 63% energy from Solar 1418 Tons CO 2 saved

22 GHG emission quantification & certification Financial Year FY FY FY FY CO 2 emission (Tons) As a responsible Corporate, we have quantified, verified & certified the GHG emissions due to Chandivli operations. These emissions were reported in public portal.
