17 Energy Conservation with investment Project 5 : Efficiency enhancing additives Efficiency enhancing additives for ductable and split ACs Investment of Rs. 1.6 lac Saving of 0.8 Lac kwh/annum ROI- 20 months HVAC

18 Energy Conservation with investment Project 6 :Updating of BMS to Equipment level monitoring Investment of Rs. 4.8 lac Saving of 0.54 Lac kwh/annum ROI- 34 months HVAC

19 Energy Conservation with investment Project 1 :Updating of BMS to Equipment level monitoring Before :- Chillers were not scheduled or sequenced After :-Able to do time scheduling and sequencing of chillers HVAC

20 Energy Conservation with investment Project 6 :Updating of BMS to Equipment level monitoring Before :- Manual intervention required for Chiller set point After :- Dynamic set point HVAC

21 Energy Conservation with investment Project 6 :Updating of BMS to Equipment level monitoring HVAC Staggering of Chiller temperature as per ambient temperature throughout the day

22 Energy Conservation with investment Project 6 :Updating of BMS to Equipment level monitoring Return air temperature monitoring CO 2 level monitoring

23 Energy Conservation with investment Project 7 : UPS Optimization Replacement of CRT PC monitors with Plasma monitors, hence reduction in IT load UPS under loaded hence less efficient. Consolidation of UPS possible with minor changes in UPS electrical distribution system.

24 Energy Conservation with investment Project 7 : UPS Optimization 3 rd & 4 th Floor load 200 kva 36% Load Removed 200 kva UPS 2 nd Floor load 160 kva 160 kva 1 st Floor load 29% Load 120 kva 24% Load 74% Load 120 kva 24% Load Investment of Rs. 1.5 lac Saving of 0.25 Lac kwh/annum ROI- 6 months Before After

25 PROJECTS-INNOVATION

26 Innovation Created a team for energy conservation as Floor Energy marshals Trained and educated them with importance of energy conservation with the help energy team and experts The energy marshal were given responsibility of energy conservation for there particular floors. Able to achieve some amount of saving by employee awareness about putting of lights, ACs whenever not required Saving of 0.1 Lac kwh

27 Innovation Team of energy marshal with pledge of Energy Conservation and Green India Each floor was designated with 8 marshals for 8 sections thus making 32 marshals

28 Innovation Floor Energy marshal being briefed and trained by our energy experts about the importance of energy conservation and how we can achieve it by taking smallsmall steps.

29 Innovation Contests and competition :- i 4 Energy Ideas for Energy conservation Best Energy marshal Quiz competitions on Energy conservation

30 Innovation POC for VFD on AHUs with temperature space sensors Conventional Design Innovative Design Saving of 0.28 Lac kwh

31 Innovation POC for VFD on AHUs VFD with temperature space sensors installed at work station area

32 Innovation Hot Desk space creation 400 SFT area is converted as hot desk-space with capacity of 16 work-stations Saving of 0.5 Lac kwh Creation of separate desk-space for Employees working in night and holidays.

33 Utilization of Renewable energy - Planned Installation of 500LPD solar water heater for Tower hot water requirement

34 Utilization of Renewable energy -Planned Installation of roof top solar power system of 20Kwp

35 Utilization of waste material as Fuel Wet waste from facility is given to Bio-Gas vendor for bio-gas production.

36 Utilization of waste material as Fuel
