Motivations

Smart Grid Energy Efficiency

Smart Cities

Our Vision: a Living Building Paradigm •  ABuilding/campus/neighborhoodthatcanautonomouslymanageitspowerconsump,on,genera,on,andcontrolasitisalivingorganisms.

•  ABuildingthatcanop,mizeenergyconsump:on•  ABuildingasMicrogrid.•  ABuildingthatiscontextaware:Itinteractswithitsoccupantsandadaptstotheirpreferences.

Living Metaphor

•  NervousSystem:madeofanetwork(wireless)ofsensors,actuators,andcompu:nginfrastructure.

•  Regulatory:BuildingControlalgorithms.•  Immunefunc,ons:Madeoffaulttolerantandfailureavoidanceanddetec:onalgorithms.

Building as a Cyber-Physical System
