SEEMPUBS: maximum energy savings with minimum intervention for historic buildings
Europe’s historic buildings draw visitors from all over the world. But keeping them energy-efficient without having to carry out significant construction work can be a struggle. The EU-funded projectSEEMPUBS plans on using a new ICT-based monitoring, visualisation and control system to reduce these buildings’ energy consumption, cope with the already-installed energy systems and avoid possible damages caused by important building interventions.
The FP7-funded SEEMPUBS project has developed a new computer-based system that can control lighting, heaters, air conditioners and other environmental units in large buildings. The SEEMPUBS technology includes a central control software system connected wirelessly to energy structures placed in different parts of a building or even a number of buildings.
Professor Enrico Macii of the Polytechnic University of Turin says that ‘beyond any actual hardware, the most significant result has been the elaboration of an energy-efficient model for existing buildings and public spaces. This model can be applied to many different historic buildings where legacy energy systems are already in place, avoiding expensive construction work, disruption and possible damage.’
The functionality of this system is already being demonstrated on existing buildings at the Politecnico Campus, and the Valentino Castle. By comparing reference and test rooms, average weekly savings ranging from 27% to 36% have been observed in heating energy in winter period. These savings ranged from 63% to 74% for cooling energy in summer period.
