Introduction (1/3)
EU Climate and Energy Package has set very ambitious targets for sustainable development (20‐20‐20).
“In 2006, urban areas accounted for 67 – 76 % of energy use and 71 – 76 % of energy‐related CO2 emissions.”
(IPCC, 2014)
“Cities and towns also produce over 70% of global energy‐related CO2 emissions.” (IEA, 2009)
“Cities consume as much as 80 percent of energy production worldwide and account for a roughly equal share of global greenhouse gas emissions”
(World Bank, 2010)
Urban GHGs emission facts

Introduction (2/3)
The term ”Smart City” is used to describe ICT solutions for cities and to highlight ICT importance and potential in helping the city to develop competitive advantages.
(Kramers A. et. al, 2014)
Smart Cities
City changes include:
smart transportation;
smart environment;
smart healthcare;
smart energy;
smart education;
smart safety etc.

Semantic Data Modeling
Implementation of a holistic interoperability solution using Semantic
Web technologies
Data Translation: Data from the original format into RDF according to a global ontology.
Data Communication: The RDF data are sent to the DSS using a publish‐and‐subscribe model (Ztreamy server).
Data Contextualization: The Semantic Service receives the RDF triples and processes them.
Data Storage: The Semantic Service uploads the final RDF triples on a triple store (e.g. Virtuoso server).

Web‐based DSS (5/10)
Prediction Models ‐ Inference Rules – Action Plans
Forecasting the behaviour of the buildings in an accurate manner becomes necessary for the implementation of the Action Plans provided by the DSS.
RapidMiner processes running on a RapidAnalytics server.
These processes can be invoked remotely as a web service.
Prediction Models
8th International Scientific Conference “Energy and Climate Change Contributing to Deep Decarbonization” 11
Web‐based DSS (6/10)
Prediction Models ‐ Inference Rules – Action Plans
Structured as a logical function (e.g. if/then) or as a mathematical model.
Able to describe the system (building, technical systems etc.) on the basis of an expert knowledge and provide the optimization criteria for a specific action.
Specific actions are associated to different strategies that allow optimizing, on one hand, a single indicator and, on the other hand, a combination of indicators.
