DIGITALIZATION AND IOT
FOR HEAT PUMPS
IoT = Internet of Things• connecting everyday objects to networks
to provide a range of services orapplications.
IoT enabled heat pumps• equipped with electronics, software,sensors and network connectivity• collect and exchange data

ENERGY TRANSITION IN THE EUExpectations for digital technologies in the energy transition:• unleash the full potential of flexible energy generation and consumption• provide system optimisation• substantial operational savings and savings in network infrastructure• support energy system integration by dynamic and interlinked flows of energy carriers• allow for more diverse markets to be connected with another• provide the necessary data to match supply and demand both at local or at systemwide level and close to real time.
• help optimising the use of the existing grid capacity and identifying bottlenecks quicker→ on-going development of an EU Action Plan for digitalisation in the energy system

IMPACT OF MITIGATION MEASURES

Digitalisation is included in
Avoided demand = energy
service demand changes
from technology
developments
Digitalisation and smart
controls enable efficiency
gains that reduce emissions
from the buildings sector by350 Mt CO2 by 2050.

MODELLING OF HEAT PUMPS
Semantic models• contain information on how data relates to the real world• information models, ontologies• Building Information Modelling (BIM)• consolidate the large number of different information
sources throughout the lifecycle of a building• planning, construction, operation, etc.
• covers architecture to building technology• upcoming: facility management
