PDCA Cycle as the Foundation of Integrated Management Systems with an Emphasis on the Energy Management System

Many organizations establish management systems that: – improves the quality of processes and process results, – improves the attitude towards the environment, – improve energy performance, etc., which represents a good path towards corporate social responsibility of the organization. All these systems are based on ISO standards, which are compatible, so they can be integrated into a single management system. The methodology on which all management systems are based is unique and is represented by the PDCA cycle. The paper will highlight the importance of the aforementioned methodology for management systems, with an emphasis on the energy management system, which leads to the improvement of energy performance: energy efficiency, energy use and consumption.Using the example of the heating and cooling system for a one shopping center, through the phases of the PDCA cycle, it will be shown how much savings i energy sources consumption and CO2 emission reduction can be achieved by using a heat pump water to water.
