The whole campus was operational from 2014

In spite of increase in the occupancy for last three years (Approx. 33% Increase) we could maintain the same consumption pattern over the period of these years.

Following factors helped us to maintain the consumption:

Design Features

Operational controls

Equipment optimization

Various energy saving initiatives such

as ATCS for chillers, LED lightsFY 2015-16 FY 2016-17 FY 2017-18

INNOVATIVE PROJECTS IMPLEMENTED IN FY 2017-18

Initiative Before After

Replacement of AHU to

achieve environmental

conditions as per TCS

work environment

guidelines

**

Energy conservation and

improved work

environment conditions

(Cost – Rs. 8.8 Lakh)

• The work area temp was around

27 Deg Celsius, causing many

complaints of discomfort.

• Standard temp was achieved

with increased chiller operations

by reducing the set point

• The circulation pumps at

building level were operated on

higher frequency

• Higher frequency setting for VFD

• Limitation of existing AHU room

to accommodate higher capacity AHU of similar type

• The vertical AHU with higher

capacity blower for increased

CFM

• Achieved desired temp and

comfort to occupants without

reducing chiller set point.

• Approx 10% of total chiller consumption units were avoided

12

Initiatives Before After

Water level monitoring system( Cost – 14.9Rs Lakh )

• We have 7 major water storage tanks at SP with a total storage capacity of 53 Lac ltrs (including Fire tanks)

• Manual checking of water levels of each tank is avoided ,which is prone to errors

• Water level sensors have been installedin the tanks to get online water tank level status.

• Monitoring is done through iBMS system.

• Helps in providing online data of overall water quantity available at any given time.
