Why SMART Buildings ?
Energy efficiency for buildings (40% of total energy usage) and districts (Smart Grid)
Retrofitting buildings (100 years lifetime) / new buildingsincremental change on existing technologies (migration strategies)
List of Sub-Systems: HVAC (Heating, Cooling, Ventilation)
Lighting
Blinds / Windows
Water supply
Solar Panels
Elevators
External Measurements
Communication with external grid
Protection (fire / intrusion detection / admission control)
