Table1. Somepossible scenarioswithourproposedsmartbuildingsystem Example Concernedentities Comfort: The temperature in a floor is detected as high. In this case, the smart building system should automatically turn on the air conditionner to an appropriate temperature, especially if there are inhabitants in the same location. The same action should be donewhen a high level of humidity or CO2 isdetectedwithin thebuilding Sensor (e.g., tempera- ture); Device (e.g., air conditioner); User (e.g., PublicData);Location Safety:Astrong storm started suddenly. The smart building system should automaticallysecureall theareasbylockingwindows,doorsandtherooftop. Also,analarmmustbe triggeredsuggestingthe inhabitants tostay insideand go to their respectivehouses Sensor (e.g., wind mea- surement);Actuator (e.g., windows); User (e.g., PublicData);Location Energy saving:Theweather suddenly becomes rainy after itwas sunny. In this case, the solar platesmust be stored tomake space forwater tanks for water collection Sensor (e.g., sun, rain); Device (e.g., solarpanels, water tanks) Security:Apersonwhich is not allowed to access thebuilding (e.g., a non- inhabitant, an uninvited and unaccompanied guest) is localized inside the building (e.g., garage, a floor). The building should be locked waiting for identityverificationandactivate the securityalarm Sensor (e.g., presence); Device (e.g., alarm),User (e.g.,PublicData) • Variable: is a constantor an inconstant todeclare forusewithin the system(e.g., clock for the time,boolean). • Thing:definedbya timeanda location. It canbeeither anapplianceorauser. • Time: the timewhenauser is located inanewlocationoranactionoccurswithin thebuilding (e.g., detectionof a sensor, change in adevice state) or outside (e.g., change in theexternal environment). It canbeaspecific time tioradelay [t1...t2]. • Location:user’s location (e.g., elevator, garage)oranappliance (e.g., rooftop). • Appliance:a smart appliance in thebuilding. It canbesensor, actuatorordevice. • Device: a smart devicewhich canbeusedby the residents or automatically initi- atedbyanactuator afterdataprocessing. • Actuator: in chargeof initiatingautomatic action(s). It is installedonobjectsnot equippedwithelectronics (e.g., door,window). • Sensor: inchargeofdetectingdifferent informationabout thebuildingfor thedata processingphase. • User: the resident profilewhich represent its information. It is definedbypublic dataandprivatedata. • PublicData: the public information about the resident such as his family name, apartmentnumber, access level andprivileges. • PrivateData: the private information about the resident such as his first name, dateofbirthandstatus.

RelatedWork In this section,we present a state of the art about design and implementationmethod- ologies of smart building systems.This domain has known some interestingworks and development in the last decades.Most of theworks focus on the energy saving aspect since, in such spaces, it is themost concern goalwith the high consumption of energy and therefore, other aspects suchcomfort,assistance, safetyand securityareneglected.
