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)

Okt 12, 2010 | Harald Schrom | Page 3 Smart networked home Envisioned solution:  Distributed embedded system  Low-power, Low-cost, long lifetime, easy to install  Dendritic networked structure – self organizing  Distributed operating system  Self-configuration, self-healing, update, maintenance  Safe and secure operation  One integrated heterogeneous system for all appliances (interfacing all other devices)  Mainly based on dependable wired links with integrated node-powering  Autonomous control system
