Summary

Universities’ campuses can be viewed as small towns due to their size, users and mixedcomplex activities, enclosing numerous actions that occur in urban districts. Energy wastage inseveral building uses, such as teaching auditoriums, working areas (offices, laboratories,computer rooms etc.) or living areas (dormitories), can be encountered. Furthermore, since theUniversity campuses comprise of buildings covered with artificial surfaces with undesirablethermal effects, along with the possible overheating by human energy release and absorption ofsolar radiation on dark surfaces of buildings, create an urban – kind climate. The energy andenvironmental impact of universities could be considerably reduced by applying organizational,technological and energy optimization measures. To design and operate a sustainable campus,it is essential to take into account – among other – the real time interaction between the indoorand outdoor environment, using sensors and metering equipment, local and global controlalgorithms and actuators to control heating, cooling, ventilation, lighting, shading and othertypes of systems. In the present work, existing Information & Communication Technology (ICT)is exploited to create a micro-grid by integrating sensors, actuators, control algorithms etc.,aiming at minimizing energy consumption of buildings and activities within the Campus. On thisbasis, the research project Camp-IT is expected to create new frontiers for research anddevelopment in energy management by considering the single building aspect as part of a“district” approach, where real time interaction of indoor and outdoor spaces is monitored andcontrolled. The aim of the Camp-IT project is to review the techniques of building modellingincorporating outdoor spaces as well as the control algorithms for energy load prediction, inorder to develop, test and validate an integrated and holistic indoor - outdoor Web basedEnergy management System for Campuses. Preliminary results indicate a potential reductionof annual energy consumption of approximately 30% due to reduction of energy waste.As a result, this project will contribute to a future smart grid community by deploying and testingof a decision support tool and optimization method for a web based energy managementsystem in real time conditions, taking into account indoor / outdoor environmental parametersand user preferences
