Page 60 Management of JK White Cement Works, Gotan appreciate every initiative taken to task force for energy saving in all areas were constructed to implement innovations by out of the box thinking. All these initiatives support to achieve target of sustainable development of JK Cement Ltd and net zero carbon emission commitment of nation in reduced around 10 KWH/Ton Cement in last 3 years. To continue our journey, we have recognized with Rajasthan Energy Conservation Award-2020 by RRECL, Jaipur, SNEMA gold award-2021 and CII award for Power quality. Air Conditioning System- expansion projects implemented time to time. VFD & PLC panels are located at various locations and for cooling of panels decentralized air conditioning units are being used. volume (VRV) system used for our Administration building. In a building Energy audit reports and literature review indicates a typical break up of Table 1. Table 1: Energy consuming areas in Commercial Building 55% 25% 15% 5% Area of Comsumption HVAC System Percentage Break-up Lighting Other auxiliaries Heating, Ventilation and Air Conditioning system (HVAC) are energy guzzlers in any air conditioned commercial buildings and panel rooms. Some of the reasons for high power system (oversize or undersize equipment), manual control of system, aged system poor in summer and more loads on AC. With improper insulation, the heat gain from the copper tubes can be increased up to 2- 5% based upon the ambient conditions. Scenario before implementation diagram- Sick Air Conditioner Low ISEER ratio Insulation degradation Room temperature sensor unavailability for exact temp monitoring Irregular temperature setting irrespective of heat dissipation Uncontrolled Manual operation of AC in VFD & PLC Panel Rooms Air Conditioner low Temp Settings Low temperature settings up to 18 Deg C AC running continuous in absence of occupancy sensor Uncontrolled Manual High Energy Consumption
