The performance of a network is strongly influenced by the location and deployment of the sensor nodes. It is judged on the yardsticks of accuracy in data sensing and reliability in communication. Hence, deployment planning must be done meticulously. It is the stepping stone to structuring a successful and viable network infrastructure. To facilitate effective management of energy consumption in structures and buildings, retrofitting or deployment of BMS (building management systems) has to be done. Existent BMSs are dependent on wired sensors for perceiving the environment. A Wireless Sensor Network (WSN) is best-suited for this task because it is more economical and faster to install or set up. Further, WSN also provides a characteristic flexibility. However, such a network doesn't fare well on grounds of reliability and network lifetime. Careful study of the environment is required before designing a WSN. This paper presents a research on the same. The paper aims at assisting a Building Management System's deployment by using wireless sensors and actuators. This is attained by developing a WSN design and using optimization software tools to support system integrators and designers when undertaking the daunting task of deploying WSN with an aim of effective energy management.
