2. Okt 12, 2010 | Harald Schrom | Page 2 Why SMART Buildings ? Energy efficiency for buildings (40% of total energy usage) and districts (Smart Grid) Retrofitting buildings (100 years lifetime) / new buildings  incremental 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)
