Dynamic Manager for Electrical Energy Efficiency in Buildings

This paper studies a management model for electrical energy efficiency that allows the integration of several alternatives energy generation sources such as wind, photovoltaic and fuel cell power in order to minimize the power consumption in a building. An intelligent approach is presented to manage the power consumption of appliances. This approach takes into account variables such as temperature, luminance and presence. The integration of several Demand Side Management (DSM) criteria are carried out through dynamic and intelligent selections according to variable performance and customer´s preferences, operation based on comfort or based on consumption. Likewise, a diagnosis analysis through energy audit is carried out to evaluate electrical appliances proficiency and customer habits. Finally, the design of a fuzzy logic-based manager is presented. This manager selects which electrical source and what proportion of energy is needed to satisfy power consumption.

Energy savings between 27% and 33% can be achieved with the proposed dynamic manager and energy audit process.
