CERTH/ITICERTH/ITIINERTIA FP7 ProjectINERTIA FP7 Project
• INERTIA, Integrating Active, Flexible and Responsive Tertiary Prosumers into a Smart Distribution Grid, FP7 EU Project
• Pilot Site at CERTH Building in Thessaloniki, Greece
• Multi-sensorial installation collecting Energy
34th Workshop on Smart Appliances Presentation, Brussels - Belgium, April 2015
• Multi-sensorial installation collecting Energy Consumption, Environmental and Occupancy Information
• DER monitoring and control through REST interfaces based on INERTIA Device ontology built for the scope of the project
• Use-case examples for the saref ontology implementation and possible extensions identified

INERTIA Device OntologyINERTIA Device Ontology--Existing Existing Approach Approach (1/2)(1/2)
• INERTIA Ontology describes three main domains addressed in the building context:
�Location
�Devices
�Occupants�Occupants
• Refers to the Energy-related BIM model and correlates Distributed Energy Resources with Sensors/Actuators
• Describes DERs such as HVACs, Lightning etc.
• Describes the WSN with a wide set of SensorActuator sub-classes representing the installed equipment.
• Application-based ontology to cover specific needs of the project

– Extension of available subclasses to address a wider variety of instances (complex devices, generation units)
– Parameters such as Temperature, utilization rates, could affect Energy profiles of other devices i.e. HVAC systems, thermostatic appliances

Possible ExtensionsPossible Extensions--ConclusionsConclusions
– Extension of Units of Measurement (Humidity units, C02 rate, occupant units etc.) for environmental and occupancy sensors
– Property saref:consistsOfDevice could be more generic (e.g. saref:hasDevice) to address the concept of different sensors/actuators attached to DERs e.g. A light monitored and controlled by a dimming sensor
– Extension of available functions/services (e.g. add phase delays for Washing Machines)
– Occupancy aspects could be taken into consideration
