Automation of Commercial Building Using PLC

International reports show about 25 to 35% energy saving potential in commercial buildings.Many buildings in India, situated in different climatic zones are energy inefficient since they were not constructed following energy conservation building codes and techniques of solar passive architecture.It is impractical to redesign and reconstruct such buildings.In such cases retrofitting of utilities provides a cost effective solution than going for altering the existing building structures.The aim of our project is to present the results generated from a detailed energy audit study conducted in an commercial buildings to propagate the awareness of energy saving potentials in Indian buildings.Based on data collection and measurement undertaken, the present case study envisages many energy-saving measures to be considered for implementation towards achieving the energy saving potential in the identified areas.The identified areas were Air conditioning, Lighting, UPSs, Power factor improvement and installation of Energy Management System (EMS).Commercial Automation means automation of commercial building.Increasing profitability is the essence of the sustainability of a commercial building or space.There are different methods of commercial automation Microcontroller based, IOT based, IED based, and PLC based automation out of that we are considering Programmable Logic Controller (PLC) based automation.
