Service-oriented architecture for smart building energy management

Energy consumption in the residential sector is a considerable source of a wide range of environmental problems. It has been mentioned that the energy consumption in this sector represents 46% of total energy consumption and 23% of greenhouse gas emissions. Technology and services can help consumers manage the energy generated by their renewable or traditional electric grid. Service oriented architecture (SOA) has recently become very popular. SOA is an approach to build distributed systems that deliver application functionality as services to end-user applications or to build other services We adopt an approach to formulate the problem of managing energy in the building in a general form of linear programming by optimizing three criteria: environmental, economic and user comfort. First, we formulate this problem into an integer linear programming (ILP) problem. A round-up heuristic algorithm which is based on linear programming relaxation is presented.
