4.2 Environmental Informatics Research Group (EIRG)

    ΓΕΝΙΚΑ

    Environmental Informatics produces and combines knowledge, methods, tools and techniques of Informatics and Environmental Engineering in order to effectively investigate the environmental status and behaviour of systems, and to solve environmental problems. It is a relatively new scientific area that touches on all activities of the Mechanical Engineer and provides solutions to problems in all areas of his/her field. It includes knowledge of Mechanical Engineering, Environmental Engineering and Computer Science to support any environmental management activity, and has strong interdisciplinary and cross-disciplinary characteristics.

    In our School, Environmental Informatics focuses particularly on (i) outdoor (urban) as well as indoor air quality issues, (ii) the design and development of information services to promote the quality of life of citizens, as well as (iii) the development of data-centric computational analysis and modelling processes using Computational Intelligence & Machine Learning to solve problems in industry. Thus, the EIRG contributes to one of the newest fields of knowledge in the Energy Sector of our School, that of Computational Intelligence in Engineering Systems and in Environmental and Energy Applications.
