The buildings' users comfort requirements are fulfilled and regulated using a fuzzy controller. The fuzzy controller's structure is adjusted to the users' requirements that are monitored via a smart card system. The IEEMS is installed in two buildings in Athens and in Crete, both in Greece. The energy conservation achieved by the IEEMS operation is more than 30% compared to the existing control system. © 2004 Elsevier B.V. All rights reserved." }
