Solutions for monitoring and analysing for energy consumption — Energy management systems

This paper analyses the procedures of selection and installation of equipment that are the basis for energy monitoring, with accuracy and technical quality, essential to the liability of the collected data. Energy efficiency plays a key role in the development of modern societies. Environmental concerns combined with the high-energy costs have a direct impact on the economic development of communities. The intensive energy consumption is currently a major concern and all sectors of activity can act to reduce consumption, increase efficiency and productivity. The sustainability of the economy in each country is directly related to its energy dependence and all mechanisms should be used to identify waste and find energy conservation opportunities. Energy audits, imposed on intensive energy consumers and energy management systems (EMS), implemented by any company, are tools whose objectives are energy characterization and rationalization of consumption in a facility. These tools may be used to analyse just the bills of electric power or, in a more complex way, the bills and the monitoring logs. These energy management systems depend directly on data analysis, which involves the installation of measuring and monitoring equipment. The visualization of equipment consumption estimates helps to optimize the energy consumption cycle and allows the analysis of the data available in order to take preventive or corrective measures that reflect the correct characterization of the installation.
