In this paper, we depict a framework that comprises a set of attributes agents to control and monitor a building infrastructure for its energy utilization. It utilizes the energy power lines for communication between the agents and the electrical devices of the building infrastructure, i.e., ventilation, sensors and actuators for lights, heating etc. The paper proposed a multi-agents methodology that is embedded through the development and usage of the product. The agents are defined to present the attributes of building like heating agent will present the Heating attributes such as solar panel and boiler. These agents are given various standards which prompt the required control strategies of the building conditions. All the Simulations are done in Matlab tool. The results of proposed work are showing improved energy efficiency in terms of energy consumption and comfort level of users.
