Buildings today are becoming more and more advanced and the demands on building services are increasing. A modern building is expected to provide a number of services with high security, energy efficiency and convenience. For a building with complex requirements due to the activity, such as a hospital, the services provided are even more advanced and the requirements on them are higher. This implies for the need of a building automation system. These systems come with a cost and have some drawbacks. This paper will take on the task to study how to benefit from the possibilities with building automation systems while minimizing the drawbacks. The aim is to find guidelines for how to design, procure and manage a building automation system in residential in an effective way. The building energy management systems its control and automation in buildings has significant role. These systems can play an important role in regular energy monitoring and management and therefore to save the possible energy and cost. The key point of the building automation market is focused upon better facilitation to the user in terms of comfort at reduced operation cost. Energy efficiency improvement will also contribute to environmental protection. Therefore there have been regulations and rating systems made that mandates the requirement of energy monitoring and control in a building. For example, the above mentioned building utilities and equipment control and automation plays an integral role in achieving the green building rating points from certifying authorities such as GRIHA and IGBC. The proposed system is to control the active systems such as lighting including artificial lighting (on/off & dimming control), air conditioners and safety features like fire alarm & gas alarm. In future the existing idea can be implemented for the whole building, i.e. various rooms or areas and then all of them can be integrated on a common platform for monitoring and control of different equipment.
