Energy Consumption Monitoring and Building Performances in a Commercial Building: Case Study

Abstract

Our paper is based on a big size commercial building in Romania, in relation to the energy consumption monitoring, to the building energy performances and to the monitoring data analysis. It contains data which will allow us to compare an existing building with the retail industry norms in terms of the building energy consumption and energy costs. The building management system (BMS) is based on SAIA Burgess Controllers with IP interface, with input/output modules both analog and digital and remote I/O modules with S-NET interface collecting signals integrated in the entire building. Based on the monitoring and data analysis, the paper's objectives are to present few action plans to implement them into this kind of buildings to achieve a better building energy efficiency. Additionally, to the main outcomes, the reduced energy costs obtained from the applied measures to improve the building energy efficiency building, there are mentioned other benefits arisen from the energy efficiency investments in building, like reducing energy use for space heating/cooling and water heating, improving interior thermal comfort, enhancing the property value, reducing the operational requirements and reducing the electrical energy for lighting, office machinery and other appliances. Some recommendations are provided to control better and efficiently the building energy use and its consumption and reducing the avoidable waste while providing to the customers the services to achieve better interior thermal comfort conditions.
