The developed algorithm consists of predicted models for outdoor/indoor air temperature using artificial neural networks, multi-step optimization using genetic algorithms and Real Time control using fuzzy techniques. The algorithm is developed in Matlab™ environment and is implemented to the existing BEMS of the Hospital, using a specialized web-based energy management and control system (Web-EMCS). The implementation of the BOC algorithm is realized by developing a “.net assembly” code, which interconnects the Web-EMCS with the existing conventional hospital's BEMS, without the need of Matlab™. The annual primary energy efficiency achieved is almost 36%.Δημοσίευση σε επιστημονικό περιοδικόhttp://creativecommons.org/licenses/by/4.0/Energy and Buildings9845–55 Sotirios Papantoniou Παπαντωνιου Σωτηριος Kolokotsa Dionysia Κολοκοτσα Διονυσια Kalaitzakis Konstantinos Καλαϊτζακης Κωνσταντινος Elsevier Building optimization Fuzzy control Neural networks
