Smart Cities have been defined in many ways. The urban urban migration leading to vertical growth in city landscape is a necessity in any smart city. Smart cities lays a lot of emphasis on Green Building and Energy Efficiency. The concept paper on Smart Cities neatly sums up the energy concerns “Good areas to focus energy efficiency measures would be the building material used, the transport system, sewerage and water supply systems, street lighting, air-conditioning systems and energy consumption in buildings.”
Building Management System (BMS) is an intelligent management system involving integration of software and hardware with the objective to manage varied electrical and mechanical systems of the Green buildings. BMS manages heating, ventilation, air-conditioning (HVAC), access control, security, lifts, transformers, DG sets, LT switchgears, water pumps, blowers and lighting requirement of any building. the systems are so designed and networked that one can get detailed drill down information about various equipment working in the building along withe their energy usages.
