In this thesis a complete methodology for efficiently managing energy resources in modern buildings is presented. The proposed methodology deals with the problem of energy management in buildings in two main directions.The first direction demonstrates a control model of a building capable of resolving functional requirements during the everyday operation including user requests, spatial variations and electromechanical equipment specification. In addition, the requirements for the assurance of the necessary thermal comfort, visual comfort and indoor air quality are fulfilled, especially in the prevailing situation of conflicting, multiple desirable conditions. The proposed methodological framework utilizes expert systems, self adaptation and knowledge engineering techniques, in order to assure the operational needs with the minimum possible energy cost and the environmental protection.The second main direction of the proposed methodology is focused on the overall energy management and energy conservation measures that can be taken in order to improve a typical building's efficiency. In this context, an innovative intelligent model for the integrated energy management of a typical building is presented. The proposed framework provides the means for the systematical analysis for all the data that are associated with building's energy consumption (loads, current operation demands, user requirements, finds) and take into account a series of external parameters (rate of interest, operational cost, funding possibilities etc) in order to propose measures, interventions and investments for energy efficiency optimization of the controlled building.The proposed overall methodology was implemented in to an information system and tested under supervision on a real office building. The findings of the experimental operation were analyzed and compared to previous energy consumption measurements indicating that the proposed framework provides one more innovative and useful tool to the problem of optimizing energy efficiency in modern buildings.
