This paper presents a competitive model for energy managment at the residential complexes in a city.This model includes cultural patterns and technical models together.The combination of culture and technology is improved energy managment at consumers side and decreased problems at utility side for energy supply. The consumer owned smart meter shared data with a control and monitoring center(CMC) through wire or wireless platform and on the other side, a data analyst application is enabled on the server and after analyzing and processing data received from the customers, the information are transmitted to a database(SQLite). A web application also uses the information stored in the database. The smart meters integrate different types of information coming from several electric or electronic devices present in buildings via ZigBee or WiFi platform.This information are shown to the building residents through graphical forms, tables and charts via web programming methods.
