Increasing energy efficiency in existing public buildings through the implementation of a Building Management System based on interoperable networks

This paper presents the results of the first phase of the 3 year project “Smart Energy Efficient Middleware for Public Spaces (SEEMPubS)” that addresses reduction in energy usage and CO2 footprint in existing Public buildings and Spaces, through an intelligent ICT-based service monitoring and managing the energy consumption. The main activities were: selection of some case-studies to be used as demonstrators; definition of suitable control strategies; development of the main software infrastructure to connect sensors and to manage the interoperability between networks produced by different manufacturers. For each case study dynamic simulations were run to estimate the annual energy demand for lighting and HVAC systems and the potential energy savings due to more efficient control strategies. The interoperability between Building Information Model tools and energy simulation tools was also addressed as part of this research
