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


• 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
